Medicaid Eligibility, Enrollment Simplification, and Coordination under the Affordable Care Act:
A Summary of CMS’s August 17, 2011 Proposed Rule and Key Issues to Consider
Executive Summary
The Affordable Care Act (ACA) increases access to health insurance beginning in 2014 through a coordinated
system of “insurance affordability programs,” including Medicaid, the Children’s Health Insurance Program
(CHIP), premium tax credits for coverage provided through new Affordable Insurance Exchanges (Exchanges),
and optional state-established Basic Health Programs. On August 17, 2011, the Centers for Medicare and
Medicaid Services (CMS) issued a proposed rule to implement the ACA provisions relating to Medicaid
eligibility, enrollment simplification, and coordination. This brief summarizes the major provisions of CMS’s
proposed rule.
Medicaid Eligibility Under Reform
CMS’s proposed rule implements the ACA provisions that expand Medicaid eligibility and simplify existing
eligibility groups. Most existing eligibility categories are collapsed into three broad groups: parents, pregnant
women, and children under age 19. As of January 2014, states must extend eligibility to a new “adult group,”
which includes all non-pregnant individuals ages 19 to 65 with household incomes at or below 133% FPL.
Further, beginning in January, 2014, states may choose to cover non-elderly individuals, including pregnant
women and children, with incomes above 133% FPL.
Under the ACA, Medicaid financial eligibility for most groups will be based on modified adjusted gross
income (MAGI), as defined in the Internal Revenue Code. The proposed rule generally adopts MAGI methods
for counting household income, eliminating all of the various income exclusions and disregards currently used
by states. CMS also proposes to generally align references to “family size” in the current Medicaid rules with
the MAGI definition of “household” and proposes household composition rules for individuals, such as non-tax
filers, who are not addressed by MAGI methods. The change to MAGI methods will result in some individuals
losing Medicaid eligibility. Certain groups are exempt from the use of MAGI and will continue to have their
financial eligibility determined based on existing Medicaid rules. CMS also proposes to amend the definition of
state residency for adults and children to simplify the language and coordinate with the Exchanges.
Under the ACA, Medicaid eligibility remains based on monthly income at the time of application, while
eligibility for premium tax credits for Exchange coverage is based on annual income. The proposed rule
provides states new options to assess continuing Medicaid eligibility based on projected annual income or by
taking into account anticipated changes in income, which would minimize coverage gaps and transitions
between Medicaid and Exchange coverage due to small income fluctuations.
Application, Enrollment and Renewal Procedures
The ACA requires the Secretary to develop a single streamlined application for all insurance affordability
programs. The application must be available for individuals to submit online, by telephone, by mail, in person,
and by fax. In addition, certain information about the Medicaid program must be made available via a website
as well as orally and in writing. Non-applicants (seeking Medicaid coverage for someone other than
themselves) may not be required to provide a Social Security number or information regarding citizenship,
nationality or immigration status. CMS proposes that state Medicaid agencies must provide assistance to
applicants in person, by telephone, and online.

Page 2
2
The Medicaid eligibility determination process will begin with a MAGI screen. If an individual is not
found eligible for a MAGI group, the state must collect necessary information and determine eligibility
under all other Medicaid eligibility categories (i.e., MAGI-exempt groups) and potential eligibility for
premium tax credits in an Exchange. CMS proposes that it develop a set of performance standards in
collaboration with the states for eligibility and enrollment in addition to the existing rule requiring non-
disability based eligibility determinations to be completed within 45 days.
States will rely, to the maximum extent possible, on electronic data matches with trusted third party
sources to verify information provided by applicants. The Secretary will establish an electronic
verification system to enable states to verify information with other federal agencies. States are
expressly permitted to accept attestation of all Medicaid eligibility criteria, except for citizenship and
immigration status, which must be verified. If information provided by an individual is “reasonably
compatible” with information obtained from other trusted sources, the agency may not request
additional information, including paper documentation, from the individual.
The rule proposes a 12-month renewal period for MAGI-based Medicaid beneficiaries. The rule further
proposes that state agencies seek to renew eligibility first based on available information. To avoid
unnecessary reapplications, CMS proposes a reconsideration period for individuals who lose coverage
because a renewal form is not returned timely, but who respond within a reasonable period of time
after coverage terminates. CMS contemplates adding a provision (not included in the proposed rule) to
extend Medicaid coverage until the end of the month in which the termination notice period ends. CMS
does not propose to extend the changes in the redetermination process to MAGI-exempt populations.
Coordination Between Medicaid and Exchanges
State Medicaid agencies will enter into one or more agreements with an Exchange and other
insurance affordability programs to coordinate eligibility determinations and enrollment. The state
Medicaid agency must ensure that any individual who is determined ineligible for Medicaid is screened
for potential eligibility for benefits available through an Exchange. The state Medicaid agency must
determine Medicaid eligibility “promptly and without undue delay” for any individual determined
potentially Medicaid-eligible by an Exchange. If an Exchange finds an individual eligible for Medicaid
under MAGI, the state agency must enroll the individual “promptly and without undue delay,” as if the
decision had been made by the state Medicaid agency. CMS proposes allowing the state Medicaid
agency to delegate MAGI eligibility determinations to Exchanges that are public agencies and seeks
comment on how to address this issue for private entity Exchanges.
Proposed Methodologies for Applying Increased Federal Medical Assistance Percentage (FMAP)
CMS proposes to allow states to choose among three methodologies to determine newly eligible
individuals whose expenditures are eligible for increased FMAP. The proposed rule also specifies the
federal matching rates for newly eligible individuals as well as the increased FMAP for expansion states
that already had opted to cover certain adults prior to the implementation of health reform.
Looking Ahead
The proposed Medicaid rule seeks to create a simple, streamlined enrollment experience for individuals.
The proposed regulations are subject to revision based upon input received during the comment period.
In reviewing the rules, it will be important for stakeholders to consider a number of issues, including the
balance of preserving Medicaid eligibility versus promoting simplicity of administration, areas where
differences in program rules or processes remain, state options versus national standards, potential
implementation challenges, as well as areas that require further information.

Introduction
The Affordable Care Act (ACA) increases access to health insurance beginning in 2014 through a
coordinated system of “insurance affordability programs,” including Medicaid, the Children’s Health
Insurance Program (CHIP), premium tax credits for coverage provided through new Affordable Insurance
Exchanges (Exchanges), and optional state-established Basic Health Programs. On August 17, 2011, the
Centers for Medicare and Medicaid Services (CMS) issued a proposed rule to implement the ACA
provisions relating to Medicaid and CHIP eligibility, enrollment simplification, and coordination.1 It also
proposed several methodologies to determine the increased federal matching payments that will be
available for state expenditures for “newly eligible” individuals and “expansion states.” Simultaneously,
the Department of Health and Human Services issued a proposed rule regarding eligibility for premium
tax credits and cost-sharing reductions and enrollment in Exchanges, and the Department of the
Treasury issued a proposed rule regarding the health insurance premium assistance tax credit.
This brief summarizes the major provisions of CMS’s proposed rule regarding Medicaid eligibility,
enrollment simplification, coordination and the proposed federal matching payment methodology.2
(This brief does not address provisions specific to the CHIP program or the provisions included in the
Exchange and Treasury proposed rules, except as they are referenced by the Medicaid provisions.)
Medicaid Eligibility Categories Under Reform
The current Medicaid eligibility system is complex with numerous eligibility categories and associated
technical criteria. These eligibility groups include both federal core groups that states are required to
cover as a condition of receiving federal Medicaid matching funds, as well as state expansion groups
that states may choose to cover with
federal funds. Until the passage of the
ACA, states could not receive federal
Medicaid matching funds to cover low-
income non-disabled, non-elderly adults
without dependent children, unless the
state obtained a waiver. Under the
current system, states have largely
expanded coverage of children and
individuals in need of institutional care.
However, income eligibility limits for
parents remain low and, in the large
majority of states, other non-disabled
adults are not eligible for Medicaid,
regardless of their income (Figure 1).
One major component of the ACA is the expansion of Medicaid eligibility to low-income adults who
were previously excluded from the program. Effective April 2011, the ACA provided a new option for
states to cover these adults. Moreover, beginning in 2014, it establishes a new minimum eligibility floor
of 133% of the federal poverty level (FPL) for adults.

Page 4

CMS’s proposed rule implements the ACA provisions that expand eligibility and consolidate most
existing Medicaid eligibility groups into broader simplified categories (Table 1). Specifically, under the
proposed rule:
Most existing Medicaid eligibility categories are collapsed into three broad groups: parents, pregnant
women,3 and children under age 19. States would set income eligibility standards for these three
groups, subject to federally specified minimums and maximums. The movement to these groups is not
intended to change current eligibility levels for these populations, but rather to streamline and
consolidate existing eligibility categories.4
As of January 2014, states must extend eligibility to a new “adult group,” which includes all non-
pregnant individuals ages 19 to 65 with household incomes at or below 133% FPL. The new adult
group effectuates the ACA’s “Medicaid expansion.” Moreover, it includes parents, adults who do not live
with dependent children, and individuals with disabilities with incomes below 133% FPL who are
currently covered at state option. Parents enrolling under this category must have their children
enrolled in Medicaid, CHIP, or other “minimum essential coverage.”
Further, beginning January 2014, states may choose to cover non-elderly individuals, who are not
otherwise eligible for Medicaid, including pregnant women and children, with incomes above 133%
FPL. Under this category, states may cover individuals up to a maximum standard set by the state.
Pursuant to an approved state plan amendment, states may phase-in coverage of the new group by
category (e.g., pregnant women, children), provided that the state does not cover people with higher
incomes before people with lower incomes are covered.5 Moreover, as with the new adult group
described above, any parents enrolled under this category must have their children enrolled in
Medicaid, CHIP, or other “minimum essential coverage.”

Table notes:
Under the proposed rule, the minimum standards will not be converted to MAGI-equivalents based on income disregards used
by the state. However, the maximum limits that are tied to states effective income levels as of March 23, 2010 (or December 31,
2013 if higher) will be converted to MAGI-equivalent thresholds that include income disregards.
The minimum standards for pregnant women and infants under age 1 will be higher for some states that had higher limits in
effect on December 19, 1989, or had authorizing legislation to do so as of July 1, 1989.

Determining Medicaid Eligibility Based on Modified Adjusted Gross Income (MAGI)
In addition to expanding Medicaid eligibility and consolidating existing eligibility categories, the ACA will
also change how financial eligibility is determined for Medicaid. As of January 2014, financial eligibility
will be based on modified adjusted gross income (MAGI) methods, as defined in the Internal Revenue
Code. The move to MAGI will result in some changes from current Medicaid rules related to calculating
family size and income and will largely align Medicaid financial eligibility determinations with the
standards used to determine eligibility for advance payments of premium tax credits and cost-sharing
reductions through the Exchanges. With regard to determining eligibility, CMS also proposes to amend
the definitions of state residency for adults and children to simplify the language and coordinate with
the Exchanges. As put forth in the proposed rule:
Medicaid financial eligibility for most eligibility categories will be based on the MAGI definition of
household income. Certain groups are exempt from use of MAGI and will continue to have their
financial eligibility determined based on existing Medicaid rules (Text Box 1). CMS proposes that states
must use MAGI methods at the next regularly scheduled eligibility determination after December 31,
2013, or March 31, 2014, whichever is later, if the individual would lose eligibility as a result of the
change to MAGI. The preamble to the proposed rule indicates that CMS may allow states to convert to
MAGI methods under a Section 1115 waiver prior to 2014.
Although MAGI is determined on an annual basis, states still must determine Medicaid eligibility
based on income as of the point in time of application. Thus, initial Medicaid eligibility for new
applicants and other individuals not receiving Medicaid at the time of their eligibility determination will
continue to be based on the current income actually available to an individual in a given month. For
current Medicaid beneficiaries subject to MAGI, CMS proposes that states may elect to base financial
eligibility determinations on either current monthly income or projected annual income, taking into
account reasonably anticipated changes in income. Actual changes in income still must be reported by
applicants and beneficiaries and acted upon by the state Medicaid agency. The option to rely on
projected annual income for current beneficiaries enables states to align Medicaid income counting
rules with the rules used to determine eligibility for premium tax credits through the Exchanges. This
would, if adopted by states, prevent coverage gaps and minimize individuals cycling between programs
Text Box 1:
Individuals Exempt from MAGI
Individuals eligible for Medicaid on a basis that does not require the determination of income by the
Medicaid agency (e.g., SSI beneficiaries)
Individuals age 65 and older
Individuals who qualify for Medicaid as blind/disabled (if income exceeds 133% FPL, and they, therefore, do
not fall into the new adult group)
Individuals whose Medicaid eligibility is based on the need for institutional or home and community-based
long-term care services, including nursing home or another level-of-care equivalent (if income exceeds
standards for new MAGI eligibility groups)
Individuals eligible for Medicare cost-sharing assistance (only for determining eligibility for Medicare cost-
sharing assistance)
Medically needy individuals (only for determining eligibility for the medically needy category)

based on small income fluctuations. CMS notes, however, that if a state does not take up this option,
individuals could be determined both ineligible for Medicaid as well as for tax credits as a result of
income fluctuations. For example, an individual employed as a landscaper can reasonably anticipate that
his income will be higher in the summer and lower in the winter. Accounting for these seasonal
fluctuations would help ensure that such individuals have continuous coverage.
The proposed rule generally adopts MAGI methods for counting household income6 and eliminates all
of the various income exclusions and disregards currently used by states.7 In addition, there are no
resource tests under MAGI. Using MAGI methods, household income will be the sum of the income of
every individual who is in the household, minus a standard income disregard of 5 percentage points of
the FPL for the applicable family size. To account for the elimination of income disregards, states must
convert their current income standards for existing Medicaid eligibility groups to MAGI-equivalent
income standards. CMS will issue separate guidance on how to make this conversion.
CMS proposes to generally align references to “family size” in the current Medicaid rules with the
definition of “household” under MAGI. CMS has determined that there are a small number of situations
in which MAGI rules and current Medicaid rules result in different household compositions. In some of
these cases, CMS has proposed to adopt the MAGI rules, noting that doing so will result in some
individuals losing Medicaid eligibility (while likely becoming eligible for coverage through an Exchange),
but promote simplicity of administration. In other cases, CMS has proposed retaining the current
Medicaid rules.8 Groups that may lose Medicaid eligibility as a result of the transition to MAGI include
children age 21 or older whose parents claim them as tax dependents; families with step-parents and
step-children in states where step-parents are not legally required to support step-children; and families
in which one or more children are required to file a tax return, where the child’s income would not
count under existing Medicaid rules. CMS also has proposed household rules for non-tax filers and
individuals who are not claimed as tax dependents, who are not addressed by MAGI methods in the
Internal Revenue Code.9
Application, Enrollment, and Renewal Procedures
In addition to the changes in eligibility categories and the eligibility determination rules, the ACA
includes requirements designed to create a simple, streamlined integrated enrollment process for
Medicaid, CHIP, and Exchange coverage. The proposed rule addresses a number of provisions related to
Medicaid application, enrollment, and renewal procedures to achieve this new system.
Applications and Application Assistance
The ACA requires the Secretary to develop and provide states with a single streamlined application for
all insurance affordability programs. CMS’s proposed rule does not address the contents of the single
streamlined application; rather, the preamble indicates that the Secretary will develop the data
elements for the application in consultation with states and consumer groups. CMS also proposes that
states may develop and use an alternative single streamlined application for all insurance affordability
programs, subject to the Secretary’s approval, that is no more burdensome than the Secretary’s
application. Future guidance will address issues related to accessibility of the application for people with
Limited English Proficiency and people with disabilities. For applicants who are not eligible under a MAGI
category, the proposed rule offers two options for gathering necessary additional information, including
using supplemental forms or developing an alternative application, subject to Secretarial approval.

Page 8
8
The application must be available for individuals to submit online, by telephone, by mail, in person,
and by fax. Moreover, states must accept applications signed electronically, including telephonically
recorded signatures, by fax, and other electronic means. Information on Medicaid eligibility
requirements, covered services, and applicant/beneficiary rights and responsibilities also must be made
available via a website as well as orally and in writing. The information must be provided in “simple and
understandable terms” and be accessible to people with disabilities and people with Limited English
Proficiency. The website must allow individuals to obtain information about, apply for, enroll in, and
renew eligibility for Medicaid and other insurance affordability programs and other activities as
appropriate
Non-applicants (seeking Medicaid coverage for someone other than themselves) may not be required
to provide a Social Security number or information regarding citizenship, nationality, or immigration
status. However, states may request Social Security numbers from non-applicants on a voluntary basis,
so long as the information is safeguarded and used only for purposes directly connected to
administration of the state Medicaid plan, such as to determine the non-applicant’s potential Medicaid
eligibility. Medicaid applicants and beneficiaries must supply Social Security numbers. Current Medicaid
regulations provide that Medicaid agencies must assist applicants with obtaining a Social Security
number if they do not have one.
CMS proposes that state Medicaid agencies must provide assistance to applicants in person, over the
telephone, and online. Such assistance must be accessible to people with disabilities and people with
Limited English Proficiency. Specifically, the proposed regulations require the state Medicaid agency to
assist “any individual seeking help with the application or redetermination process.” CMS will provide
additional sub-regulatory guidance and technical assistance in this area, and notes that the ACA includes
a directive for states to conduct outreach to vulnerable underserved populations, with a particular focus
on the newly eligible, people with disabilities, and underserved minorities.
Streamlined Enrollment Process
The Medicaid eligibility determination process will begin with a MAGI screen (see Figure 1, next page).
For every individual who submits an application and meets the non-financial eligibility criteria, the state
Medicaid agency first must assess whether the individual has household income at or below the
applicable MAGI standard. Based on this initial screen, the state must provide Medicaid “promptly and
without undue delay” to individuals with household income at or below the applicable MAGI standard. If
the state provides coverage to the new optional group of individuals with household income above
133% FPL, it must determine individuals eligible under that group, unless the state can determine
eligibility for another optional coverage group (e.g., disability, level of care, resources) based solely on
the information available in the application.
If an individual is not found eligible for a MAGI group, the state must then collect the necessary
information and determine eligibility under all other Medicaid eligibility categories (i.e., MAGI-
exempt groups) and potential eligibility for premium tax credits in an Exchange. Medicaid eligibility
determinations based on blindness or disability status should occur at the same time as the state
Medicaid agency’s assessment of potential eligibility for premium tax credits in an Exchange. Those
determined eligible through another Medicaid category must be provided benefits “promptly and
without undue delay.” For those found to be potentially eligible for premium tax credits in an Exchange,
the state Medicaid agency must provide the individual’s electronic account to the other program

Page 9

“promptly and without undue delay.” If eligible, individuals should receive premium tax credits while
their eligibility for Medicaid based on disability status is being determined.
CMS proposes that it collaborate with states to develop performance standards and metrics for the
streamlined coordinated eligibility and enrollment system, which are not contained in the proposed
rule. While the existing rule that state agencies must determine eligibility on a Medicaid application
within a maximum of 45 days for non-disability-based applicants is retained (and redesignated) in the
proposed rule, that standard does not explicitly apply as an outside limit for enrolling eligible applicants,
nor is it clear that the existing standard applies to MAGI populations.

Verification of Eligibility
CMS’s proposed rule streamlines and simplifies the eligibility verification process, seeking to minimize
burdens on states and applicants. However, CMS reaffirms that nothing in the proposed rule shall
prevent states from acting to ensure program integrity.
States will rely, to the maximum extent possible, on electronic data matches with trusted third party
data sources to verify information provided by applicants. Before a request for a third party data
source is initiated, the individual must receive notice of the information being requested and its use.
The ACA provides that state Medicaid agencies must conduct electronic data matches to obtain income
information from state quarterly wage reports, unemployment compensation, the IRS and the Social
Security Administration, if such information would be useful to verify Medicaid eligibility as determined
by the Secretary. CMS proposes delegating to the states the Secretary’s discretion regarding whether
information would be useful to verify Medicaid financial eligibility and therefore must be requested.
Moreover, the proposed rule eliminates a number of current prescriptive provisions regarding when and
how often states must query certain data sources and deletes current language requiring independent
verification of information “if determined appropriate by agency experience.”
The Secretary must establish a secure electronic verification system through which all insurance
affordability programs can verify certain eligibility information with other federal agencies. At a
minimum, this system will allow for verification of household income and family size with the IRS,
citizenship with the Social Security Administration, and immigration status with the Department of
Homeland Security. CMS proposes that, to the extent available, states must access needed financial and
non-financial information through the Secretary’s system. Information not available through the
Secretary’s system may be obtained directly from the agency or program housing the information.
States are expressly permitted to accept attestation of all Medicaid eligibility criteria, except for
citizenship and immigration status. Attestation may be by the applicant/beneficiary or by a parent,
caretaker, or other person acting responsibly on the individual’s behalf. To ensure program integrity,
states must request information from trusted data sources when useful to verify financial eligibility.
Pregnancy should be verified by self-attestation, unless the state has other information, such as claims
history, that is not reasonably compatible. The proposed rule also specifies that documents that provide
information regarding immigration status may not alone be used to determine lack of state residency,
because some temporary or time-limited statuses may be routinely renewed.
If information provided by an individual is “reasonably compatible” with information obtained from
other trusted sources, the agency may not request additional information from the individual. The
proposed rule does not define “reasonably compatible.” However, the preamble explains that it does
not necessarily mean an identical match, but only that the information is generally consistent, and that
states will have flexibility in applying the standard, which may vary depending upon particular
circumstances. If the agency is unable to obtain information electronically, or if the information
obtained is not reasonably compatible with that provided by the individual, the agency may contact the
individual and accept the individual’s reasonable explanation of the discrepancy without further
documentation, or the agency may request and provide the individual with a reasonable amount of time
to supply additional information, including paper documentation. The agency shall not deny or
terminate eligibility based on information it has received from another source unless the agency has
sought additional information from the individual and provided the individual with proper notice and
hearing rights.

Medicaid Eligibility Redeterminations
The rule proposes a 12-month renewal period for Medicaid beneficiaries whose eligibility is based on
MAGI. However, eligibility should be redetermined more frequently if a beneficiary reports a change in
circumstances that may affect eligibility or if the agency obtains information, such as through a data
match, that indicates the need for review. CMS proposes deleting the existing standard requiring agency
action within 45 days of the date new information is received, and instead proposes that the agency
redetermine eligibility “promptly” when it receives information about changes in a beneficiary’s
circumstances that may affect eligibility and “at the appropriate time” when it receives information
about anticipated changes in circumstances.
The rule further proposes that state agencies seek to renew eligibility first by evaluating information
from the individual’s electronic account or from other more current reliable data sources. If the
available information is sufficient to determine continued Medicaid eligibility, coverage shall be
renewed, and the agency would send an appropriate notice without requiring the individual to sign and
return the notice. Beneficiaries must correct any inaccurate information in the notice online, in person,
by telephone or by mail. If the agency cannot determine that the individual remains eligible based on
available information, it must then provide the individual with a pre-populated form containing the
information relevant to renewal that is available to the agency, and a reasonable period of time, at least
30 days, for the individual to provide the necessary information and correct any inaccuracies online, in
person, by telephone or by mail. The agency is to verify the information reported by the individual,
including a state option to rely on self-attestation.
To avoid unnecessary reapplications, CMS proposes a reconsideration period for individuals who lose
coverage because the renewal form is not returned timely, but who respond within a reasonable
period of time after coverage terminates. CMS is considering a 90 day reconsideration period but has
not specified a particular time period in the proposed regulations.
CMS has not proposed amending the redetermination process for MAGI-exempt Medicaid
beneficiaries. Instead, the proposed rule retains the provision that eligibility must be redetermined “at
least every 12 months” for non-MAGI groups. However, the agency is seeking comment on whether the
new proposed renewal procedures described above also should apply to MAGI-exempt beneficiaries.
CMS’s proposed rule does extend the new change reporting methods (online, by telephone, by mail, and
in person) to MAGI-exempt populations.
CMS contemplates adding a provision (which is not included in the proposed rule) to extend Medicaid
coverage until the end of the month in which the Medicaid termination notice period ends. Current
law requires the state agency to provide at least 10 days advance notice of termination actions. Under
the proposed Exchange rule, individuals who lose Medicaid eligibility can enroll in an Exchange on the
first day of the month following the date of Medicaid termination and determination of Exchange
eligibility. However, if the individual loses Medicaid eligibility and is determined eligible for an Exchange
after the 22nd day of the month, enrollment through the Exchange would begin on the first day of the
second month following such date. The proposed rule invites comment on extending Medicaid coverage
until the end of the month in which the Medicaid termination notice period ends to prevent gaps in
coverage for those receiving notice after the 22nd of the month.

Coordination Between Medicaid and Exchanges
State Medicaid agencies must participate in the coordinated eligibility and enrollment system under the
ACA. The proposed rule addresses a number of provisions related to how Medicaid will coordinate with
eligibility for premium tax credits in the Exchanges10 to determine eligibility and enroll individuals in
coverage.
The state Medicaid agency must determine Medicaid eligibility promptly and without undue delay for
any individual determined potentially Medicaid-eligible by an Exchange. The Medicaid agency may
not request any information already obtained or duplicate any eligibility verifications already performed
by an Exchange and included in the individual’s electronic account. Once the Medicaid determination is
complete, the state Medicaid agency should notify the Exchange of the individual’s Medicaid eligibility
or ineligibility. Future rule-making will address notices about coordinated eligibility.
If an Exchange finds an individual eligible for Medicaid based on the applicable MAGI standard, the
state agency must enroll the individual promptly and without undue delay, as if the decision had been
made by the state Medicaid agency. The preamble clarifies that, in such circumstances, the state
Medicaid agency shall not make any further determination. The state agency must establish procedures
to receive, via secure electronic data interface from an Exchange, the finding of Medicaid eligibility and
the individual’s electronic account, including all application information. While an actual data transfer
may not occur if the Medicaid agency and Exchange use a shared electronic eligibility system, legal
responsibility for the electronic account and for taking further action would transfer from the Exchange
to the state Medicaid agency.
The state Medicaid agency must ensure that any individual who is determined ineligible for Medicaid
upon an initial application or at redetermination is screened for potential eligibility for premium tax
credits, cost-sharing reductions, and enrollment in a qualified health plan through an Exchange.
Absent an agreement through which the state Medicaid agency makes Exchange eligibility
determinations, the state Medicaid agency must promptly transfer the electronic account of individuals
screened as potentially eligible to an Exchange so that such individuals can receive an immediate
eligibility determination by the Exchange and, if eligible, enroll without delay. The electronic account
information transferred should include the Medicaid ineligibility determination, all information provided
on the single streamlined application and any appropriate verifications obtained by the state Medicaid
agency. An Exchange or other entity with delegated authority to render Medicaid eligibility decisions
cannot reverse a determination of Medicaid ineligibility made by the state Medicaid agency. Individuals
determined ineligible for Medicaid based on MAGI, for whom the Medicaid agency is evaluating
eligibility under blindness or disability, may enroll in a qualified health plan under an Exchange while the
final Medicaid determination is pending. If the individual is ultimately found Medicaid eligible, the other
coverage would terminate in favor of Medicaid.
To implement these arrangements, state Medicaid agencies will enter into one or more agreements
with the Exchanges and other insurance affordability programs that determine Medicaid eligibility. In
the preamble to the proposed rule, CMS envisions three broad options for the design of such
agreements: one or more entities could agree to have some or all of the responsibilities of each to be
performed by one or more of the others; a single integrated entity that performs all responsibilities
could be established; or each entity could fulfill its own responsibilities and establish strong connections
to the other entities to ensure the seamless exchange of information and data. Regardless, the single
state Medicaid agency must retain authority to administer and supervise the Medicaid program and

Page 15
15
ensure that an Exchange or other entity performing delegated functions acts consistently with the state
Medicaid agency’s rules. Moreover, state Medicaid agencies must certify the criteria necessary for an
Exchange to use when determining Medicaid eligibility under MAGI, including income standards and
criteria for determining satisfactory immigration status. CMS invites comment on other rules that should
be so certified.
The scope of final Medicaid eligibility determinations made by Exchanges is limited to MAGI groups.
The preamble notes that, in certain circumstances, the state may establish procedures whereby an
Exchange will undertake Medicaid eligibility determinations on other bases, and the proposed Exchange
rules provide that all applicants have the right to request and receive a full determination for eligibility
on bases other than MAGI from the state Medicaid agency.
CMS proposes allowing the state Medicaid agency to delegate MAGI eligibility determinations to
Exchanges that are public agencies. In these cases, the Medicaid agency would retain discretion for
administering and supervising the state Medicaid plan and implementing quality control and oversight
procedures. For Exchanges that are non-governmental entities, the preamble notes that Medicaid state
workers may need to be co-located at the Exchange or other accommodations may be necessary to both
meet the ACA’s coordination requirements and to fulfill the single Medicaid state agency requirements,
including that state Medicaid plans be administered pursuant to merit based personnel standards. CMS
solicits comments on whether a private entity Exchange should conduct Medicaid eligibility
determinations, which historically have not been permitted as they involve discretion that is inherently
governmental in nature.
Proposed Methodologies for Applying Increased Federal Matching Rates
The ACA provides a significant increase in the federal medical assistance percentage (FMAP) for federal
matching funds for newly eligible individuals. For 2014 through 2016, states would receive an FMAP of
100% for newly eligible individuals, which would phase down to 90% in 2020 and beyond. A separate
match rate formula applied to “expansion states” (certain states that had opted to cover parents and
childless adults with incomes at or above 100% of poverty on March 23, 2010).
The proposed rule specifies the federal matching rates for newly eligible individuals as well as the
increased FMAP for expansion states. There are some differences in how newly eligible individuals have
been defined in the proposed rule versus the legislation, which could result in fewer individuals
qualifying as newly eligible and receiving the increased FMAP.
CMS proposes to allow states to choose among three methodologies to determine newly eligible
individuals whose expenditures are eligible for increased FMAP. The first proposed methodology
assesses whether individuals are “newly eligible” based on an approximation of the state’s 2009
eligibility standards that have been converted to a MAGI-equivalent standard. The second proposal uses
a statistically valid sampling methodology across individuals in the new adult group and their related
Medicaid expenditures to make a statistically valid extrapolation of which individuals are newly eligible.
The third proposal calculates the proportion of individuals covered under the new adult group who are
newly eligible, as compared to December 2009 eligibility standards, by extrapolating from reliable data
sources, such as the MEPS or MSIS. CMS seeks comments on alternative methods that should be
considered, if it is advisable to allow states to choose a method or if HHS should identify a single method
for all states and on methods or proxies that could be used in identifying new versus current eligible for
matching purposes related to assets and disability determinations. The goal is to establish a system for

Page 16
16
determining the appropriate matching rates for states without interfering with other goals of simplifying
and streamlining the enrollment process.
An increased FMAP also is available to expansion states that already had opted to cover certain adults
as of March 2010. The expansion state enhanced FMAP is determined by increasing the expansion
state’s base FMAP by a specified “transition percentage,” multiplied by the difference between the
newly eligible FMAP available in 2014 and the expansion state’s base FMAP, with a goal of reaching a 90
percent enhanced FMAP in both newly eligible and expansion states by 2020. Expansion states also are
eligible for a 2.2 percent increase in their base FMAPs for all Medicaid expenditures (not only those for
newly eligibles) in 2014 and 2015.
Looking Ahead
Overall, the proposed rule from CMS implements the ACA’s vision of a simplified, integrated enrollment
system for all insurance affordability programs that is technology-driven and relies on electronic data-
matching to the greatest extent possible. The rule effectuates the ACA’s transformative change to
Medicaid eligibility rules and enrollment and renewal processes, which will have significant impacts on
applicants, enrollees, and state Medicaid agencies. In examining the potential impacts of the rule, there
a number of key issues to consider, including the following:
Balancing interests to preserve Medicaid coverage and promote simplicity of administration. As
noted in the preamble to the proposed rule, the transition to the new Medicaid eligibility categories
and to MAGI methods to determine financial eligibility is not intended to affect the eligibility status
of existing populations. However, some individuals will lose Medicaid coverage as a result of the
transition, while likely becoming eligible for premium tax credits in an Exchange. CMS notes that in
developing the proposed rule, it sought to balance the sometimes competing interests of preserving
existing Medicaid eligibility with its goal of promoting simplicity of administration through
coordination and alignment of Medicaid rules and processes with the Exchanges. As such, in
reviewing the proposed rule, it will be important to consider what may happen to groups losing
Medicaid eligibility under the proposed rule and whether their loss of coverage is balanced by the
benefits of administrative simplicity.
Differences in program eligibility and enrollment rules. The overarching goal of the proposed
Medicaid rule, along with the accompanying Exchange and Treasury rules, is to create an integrated
and aligned eligibility and enrollment system. However, there are a number of areas in which
distinctions and differences in processes and rules remain. For example, within Medicaid, a number
of the proposed changes and simplifications will apply to MAGI-groups but not to groups exempt
from MAGI. Moreover, under the ACA, Medicaid eligibility remains based on monthly income at the
time of application, while eligibility for premium tax credits for Exchange coverage is based on
annual income. The proposed rule seeks to address this distinction in timing by providing states
options to assess income eligibility for Medicaid in ways that more closely align to annual income.
However, if states do not take up these options, there is the potential for some individuals to be
determined ineligible simultaneously for both Medicaid and Exchange coverage as a result of the
distinction in the time period for financial eligibility. As the proposed rule is reviewed, it will be
important to identify areas in which differences exist and assess the potential impacts of these
differences and whether there are any opportunities for further alignment and/or coordination.

State options versus nationwide standards and processes. There are also some areas of the
proposed rule that provide states options with regard to eligibility and enrollment processes. While
providing options gives states flexibility to implement processes in ways that meet their specific
interests or situations, it also results in increased state variation in rules and processes, which can
contribute to increased administrative complexity and have implications for individuals. For
example, relying on projected annual income to assess Medicaid eligibility is an option for states,
which some states may choose to utilize while others may not. As noted in the preamble to the rule,
in states that do not take up the option, individuals will be more likely to experience coverage gaps
due to small fluctuations in income. Moreover, providing states options with regard to the
methodology used to track newly eligible individuals for federal matching purposes would likely
result in significant administrative complexities.
Potential implementation challenges. While the proposed rule creates an eligibility and enrollment
process that is designed to be simple and streamlined for individuals, achieving that system will
require state Medicaid agencies, working with the Exchanges, to make significant process and
systems changes and to create systems that can operationalize and automate the new eligibility
determination rules. Application of the new rules is dependent on a number of factors including a
person’s tax filing status, household composition, and the program for which eligibility is being
assessed. As such, operationalizing and automating the rules may present challenges and
complexities that will be important to identify and help states develop methods to address.
Provisions requiring further clarification and information. There are a number of provisions in the
proposed rule that require further information and clarification. For example, the proposed
regulations direct states to convert their existing maximum income standards for Medicaid and CHIP
eligibility groups to MAGI-equivalents, but more guidance is needed regarding how states will make
this conversion. Moreover, the proposed rule eliminates certain timeliness standards to be replaced
with performance standards that have not yet been developed. In addition, CMS proposes a
“reasonable compatibility” standard that governs when states may request additional information,
including documentation, from individuals to verify eligibility criteria. While this proposal seeks to
minimize burdens on states and individuals, it could be subject to various interpretations, and CMS’s
explanation of what it considers “reasonably compatible” is not included in the proposed rule. In
some cases, further information on the provisions is necessary to understand the full implications of
the proposed policies and/or changes. Finally, while the proposed rule generally does not address
the benefits individuals will receive, it is important to note that eligibility rules and processes may
have a significant impact on individuals’ benefits, since states may choose to provide individuals in
some eligibility categories more limited benefit packages.
In conclusion, CMS’s proposed Medicaid eligibility and enrollment rules are an important step forward in
the ACA implementation process. The final regulations are subject to revision based upon input received
during the comment period. In reviewing the proposed rules, it will be important for stakeholders to
consider a number of issues, including the balance of preserving Medicaid eligibility versus promoting
simplicity of administration, areas where differences in program eligibility rules or enrollment processes
remain, state options versus national standards, potential implementation challenges facing states, as
well as areas that require further clarification or information.

2 Note that CMS’s proposed CHIP regulations apply to states with separate CHIP programs, while state CHIP
programs that are part of a Medicaid expansion are governed by the applicable proposed Medicaid regulations.
3 CMS’s proposed rule addresses only one area related to the benefits package to be provided to Medicaid
beneficiaries under the new system. Currently, states may limit Medicaid coverage to only pregnancy-related
services for pregnant women at higher incomes. CMS’s proposed rule would provide full Medicaid coverage to all
pregnant women, unless the state elects to provide only pregnancy-related, or enhanced pregnancy-related,
services to pregnant women with incomes above a certain limit established by the state in accordance with
specified federal minimum and maximum standards.
4 For a summary of how current mandatory and optional groups would be moved into the proposed new groups,
see Table 1 at 76 Fed. Reg. 51153.
5 The preamble to the proposed rule provides that if a state currently covers children with household incomes
above 133% FPL in a separate CHIP program and elects this new optional Medicaid eligibility group, the state must
transition the affected children from CHIP to Medicaid but still would be able to claim the enhanced CHIP FMAP for
those children.
6 CMS recommends retaining the current Medicaid income counting rules in three instances: lump sum payments
would continue to be counted as income in the month received rather than in the year received; scholarships and
grants for educational purposes, and not living expenses, would continue to be excluded from countable income;
and certain types of American Indian and Alaskan Native income would continue to be excluded from countable
income.
7 Because each state’s net countable income standard converted to a MAGI-equivalent will be lower than its
current gross income standard (at or below 185% of the state’s consolidated standard of need for the AFDC
program as of July 16, 1996), the gross income test for parents/caretaker relatives also is eliminated under MAGI.
8 For more detail on the specific groups affected, see 76 Fed. Reg. 51157-58 and proposed 42 C.F.R. § 435.603(f)(1),
(2).
9 Specifically, CMS proposes to include spouses living together and spouses/parents (including step-parents) and all
children (including step-children and step-siblings) under age 19 (or if a full-time student, under age 21), who live
together in the same household. Non-tax filers, other than spouses or biological, adoptive or step-parents, children
or siblings, are not included in the same household.
10 Coordination also is required between Medicaid, a separate CHIP program, and the Exchanges.
