Medicaid Program Description and Legislative History
The following are brief summaries of complex subjects. They should be used only as overviews and general guides to the Medicare and Medicaid programs. The views expressed herein do not necessarily reflect the policies or legal positions of the Centers for Medicare & Medicaid Services (CMS) or the Department of Health and Human Services (HHS). These summaries do not render any legal, accounting, or other professional advice, nor are they intended to explain fully all of the provisions or exclusions of the relevant laws, regulations, and rulings of the Medicare and Medicaid programs. Original sources of authority should be researched and utilized.1
Title XIX of the Social Security Act is a federal and state entitlement program that pays for medical assistance for certain individuals and families with low incomes and resources. This program, known as Medicaid, became law in 1965 as a cooperative venture jointly funded by the federal and state governments (including the District of Columbia and the Territories) to assist states in furnishing medical assistance to eligible needy persons. Medicaid is the largest source of funding for medical and health-related services for America's poorest people.
Within broad national guidelines established by federal statutes, regulations, and policies, each state (1) establishes its own eligibility standards; (2) determines the type, amount, duration, and scope of services; (3) sets the rate of payment for services; and (4) administers its own program. Medicaid policies for eligibility, services, and payment are complex and vary considerably, even among states of similar size or geographic proximity. Thus, a person who is eligible for Medicaid in one state may not be eligible in another state, and the services provided by one state may differ considerably in amount, duration, or scope from services provided in a similar or neighboring state. In addition, state legislatures may change Medicaid eligibility, services, and reimbursement during the year.
Basis of Eligibility and Maintenance Assistance Status
Medicaid does not provide medical assistance for all poor persons. Under the broadest provisions of the federal statute, Medicaid does not provide health care services even for very poor persons unless they are in one of the groups designated below. Low income is only one test for Medicaid eligibility for persons within these groups; their resources also are tested against threshold levels (as determined by each state within federal guidelines).
States generally have broad discretion in determining which groups their Medicaid programs will cover and the financial criteria for Medicaid eligibility. To be eligible for federal funds, however, states are required to provide Medicaid coverage for certain individuals who receive federally assisted income-maintenance payments, as well as for related groups not receiving cash payments. In addition to their Medicaid programs, most states have additional "state-only" programs to provide medical assistance for specified poor persons who do not qualify for Medicaid. Federal funds are not provided for state-only programs. The following enumerates the mandatory Medicaid "categorically needy" eligibility groups for which federal matching funds are provided:
- Individuals, in general, who meet the requirements for the Aid to Families with Dependent Children (AFDC) program that were in effect in their state on July 16, 1996
- Children under the age of 6 whose family income is at or below 133 percent of the federal poverty level (FPL)
- Pregnant women whose family income is below 133 percent of the FPL (services to these women are limited to those related to pregnancy, complications of pregnancy, delivery, and postpartum care)
- Supplemental Security Income (SSI) recipients in most states (some states use more restrictive Medicaid eligibility requirements that predate SSI)
- Recipients of adoption or foster care assistance under Title IV of the Social Security Act
- Special protected groups (typically individuals who lose their cash assistance because of earnings from work or from increased Social Security benefits but who may keep Medicaid for a period of time)
- All children under the age of 19, in families with incomes at or below the FPL
- Certain Medicare beneficiaries (described later)
States also have the option of providing Medicaid coverage for other "categorically related" groups. These optional groups share characteristics of the mandatory groups (that is, they fall within defined categories), but the eligibility criteria are somewhat more liberally defined. The broadest optional groups for which states will receive federal matching funds for coverage under the Medicaid program include the following:
- infants up to the age of 1 and pregnant women not covered under the mandatory rules whose family income is no more than 185 percent of the FPL (the percentage amount is set by each state);
- children under the age of 21 who meet criteria more liberal than the AFDC income and resources requirements that were in effect in their state on July 16, 1996;
- institutionalized individuals eligible under a "special income level" (the amount is set by each state—up to 300 percent of the SSI federal benefit rate);
- individuals who would be eligible if institutionalized, but who are receiving care under home and community-based services (HCBS) waivers;
- certain aged, blind, or disabled adults who have incomes above those requiring mandatory coverage but below the FPL;
- recipients of state supplementary income payments;
- certain working-and-disabled persons with family income less than 250 percent of the FPL who would qualify for SSI if they did not work;
- tuberculosis-infected persons who would be financially eligible for Medicaid at the SSI income level if they were within a Medicaid-covered category (however, coverage is limited to tuberculosis-related ambulatory services and tuberculosis drugs);
- certain uninsured or low-income women who are screened for breast or cervical cancer through a program administered by the Centers for Disease Control and Prevention (the Breast and Cervical Cancer Prevention and Treatment Act of 2000 [Public Law 106-354] provides these women with medical assistance and follow-up diagnostic services through Medicaid);
- "optional targeted low-income children" included within the State Children's Health Insurance Program (SCHIP) established by the Balanced Budget Act (BBA) of 1997 (Public Law 105-33); and
- medically needy persons (described below).
The medically needy (MN) option allows states to extend Medicaid eligibility to additional persons. These persons would be eligible for Medicaid under one of the mandatory or optional groups, except that their income or resources or both are above the eligibility level set by their state. Persons may qualify immediately or may spend down by incurring medical expenses that reduce their income to or below their state's MN income level.
Medicaid eligibility and benefit provisions for the medically needy do not have to be as extensive as for the categorically needy and may be quite restrictive. Federal matching funds are available for MN programs. However, if a state elects to have a MN program, there are federal requirements that certain groups and certain services must be included, for example, children under the age of 19 and pregnant women who are medically needy must be covered, and prenatal and delivery care for pregnant women, as well as ambulatory care for children, must be provided. A state may elect to provide MN eligibility to certain additional groups and may elect to provide certain additional services within its MN program. As of 2003, 36 states plus the District of Columbia have elected to have a MN program and are providing at least some MN services to at least some MN beneficiaries. All remaining states utilize the special-income-level option to extend Medicaid to the near poor in medical institutional settings.
The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (Public Law 104-193)— known as the welfare reform bill—made restrictive changes regarding eligibility for SSI coverage that had an impact on the Medicaid program. For example, legal resident aliens and other qualified aliens who entered the United States on or after August 22, 1996, are ineligible for Medicaid for 5 years. States have the option of providing Medicaid coverage for most aliens entering before that date and coverage for those eligible after the 5-year ban; emergency services, however, are mandatory for both of these alien coverage groups. For aliens who lose SSI benefits because of the new restrictions regarding SSI coverage, Medicaid coverage for them can continue only if these persons can be covered under some other eligibility status (again with the exception of emergency services, which are mandatory). Public Law 104-193 also affected a number of disabled children, who lost SSI as a result of the restrictive changes; however, their eligibility for Medicaid was reinstituted by Public Law 105-33, the BBA.
In addition, welfare reform repealed the open-ended federal entitlement program known as Aid to Families with Dependent Children (AFDC) and replaced it with Temporary Assistance for Needy Families (TANF), which provides states with grants to be spent on time-limited cash assistance. TANF generally limits a family's lifetime cash welfare benefits to a maximum of 5 years and permits states to impose a wide range of other requirements as well—in particular, those related to employment. However, the impact on Medicaid eligibility has not been significant. Under welfare reform, persons who would have been eligible for AFDC under the AFDC requirements in effect on July 16, 1996, are generally still eligible for Medicaid. Although most persons covered by TANF receive Medicaid, it is not required by law.
Title XXI of the Social Security Act, known as the State Children's Health Insurance Program (SCHIP), is a program initiated by the BBA. In addition to allowing states to craft or expand an existing state insurance program, SCHIP provides more federal funds for states to expand Medicaid eligibility to include a greater number of children who are currently uninsured. With certain exceptions, these are low-income children who would not qualify for Medicaid on the basis of the plan that was in effect on April 15, 1997. Funds from SCHIP also may be used to provide medical assistance to children during a presumptive eligibility period for Medicaid. This is one of several options from which states may select to provide health care coverage for more children, as prescribed within the BBA's Title XXI program.
Medicaid coverage may begin as early as the third month before application—if the person would have been eligible had he or she applied during that time. Medicaid coverage generally stops at the end of the month in which a person no longer meets the criteria of any Medicaid eligibility group. The BBA allows states to provide 12 months of continuous Medicaid coverage (without reevaluation) for eligible children under the age of 19.
The Ticket to Work and Work Incentives Improvement Act of 1999 (Public Law 106-170) provides or continues Medicaid coverage to certain disabled beneficiaries who work despite their disability. Beneficiaries with higher incomes may pay a sliding-scale premium based on income.
The Deficit Reduction Act (DRA) of 2005 (Public Law 109-171) refined eligibility requirements for Medicaid beneficiaries by tightening standards for citizenship and immigration documentation and by changing the rules concerning long-term care eligibility—specifically, the look-back period for determining community spouse income and assets has been lengthened from 36 months to 60 months, individuals whose homes exceed $500,000 in value are disqualified, and the states are required to impose partial months of ineligibility.
Scope of Medicaid Services
Title XIX of the Social Security Act allows considerable flexibility within states' Medicaid plans. However, some federal requirements are mandatory if federal matching funds are to be received. A state's Medicaid program must offer medical assistance for certain basic services to most categorically needy populations. These services generally include the following;
- inpatient hospital services
- outpatient hospital services
- prenatal care
- vaccines for children
- physician services
- nursing facility services for persons aged 21 or older
- family planning services and supplies
- rural health clinic services
- home health care for persons eligible for skilled-nursing services
- laboratory and X-ray services
- pediatric and family nurse practitioner services
- nurse-midwife services
- federally qualified health center (FQHC) services and ambulatory services of an FQHC that would be available in other settings
- early and periodic screening, diagnostic, and treatment (EPSDT) services for children under the age of 21
States may also receive federal matching funds to provide certain optional services. Following are the most common of the 34 currently approved optional Medicaid services:
- diagnostic services
- clinic services
- intermediate care facilities for the mentally retarded (ICFs/MR)
- prescribed drugs and prosthetic devices
- optometrist services and eyeglasses
- nursing facility services for children under the age of 21
- transportation services
- rehabilitation and physical therapy services
- home and community-based care to certain persons with chronic impairments
The BBA included a state option known as Programs of All-inclusive Care for the Elderly (PACE). PACE provides an alternative to institutional care for persons aged 55 and older who require a nursing facility level of care. The PACE team offers and manages all health, medical, and social services and mobilizes other services as needed to provide preventive, rehabilitative, curative, and supportive care. This care, provided in day health centers, homes, hospitals, and nursing homes, helps the person maintain independence, dignity, and quality of life. PACE functions within the Medicare program as well. Regardless of source of payment, PACE providers receive payment only through the PACE agreement and must make available all items and services covered under both Titles XVIII and XIX, without amount, duration, or scope limitations and without application of any deductibles, copayments, or other cost sharing. The individuals enrolled in PACE receive benefits solely through the PACE program.
Amount and Duration of Medicaid Services
Within broad federal guidelines and certain limitations, states determine the amount and duration of services offered under their Medicaid programs. States may limit, for example, the number of days of hospital care or the number of physician visits covered. Two restrictions apply: (1) limits must result in a sufficient level of services to reasonably achieve the purpose of the benefits, and (2) limits on benefits may not discriminate among beneficiaries on the basis of medical diagnosis or condition.
In general, states are required to provide comparable amounts, duration, and scope of services to all categorically needy and categorically related eligible persons. There are two important exceptions: (1) medically necessary health care services that are identified under the EPSDT program for eligible children, and that are within the scope of mandatory or optional services under federal law, must be covered even if those services are not included as part of the covered services in that state's plan, and (2) states may request waivers to pay for otherwise uncovered home and community-based services (HCBS) for Medicaid-eligible persons who might otherwise be institutionalized. As long as the services are cost effective, states have few limitations on the services that may be covered under these waivers (except that, other than as a part of respite care, states may not provide room and board for the beneficiaries). With certain exceptions, a state's Medicaid program must allow beneficiaries to have some informed choices among participating providers of health care and to receive quality care that is appropriate and timely.
Payment for Medicaid Services
Medicaid operates as a vendor payment program. States may pay health care providers directly on a fee-for-service basis, or states may pay for Medicaid services through various prepayment arrangements, such as health maintenance organizations (HMOs). Within federally imposed upper limits and specific restrictions, each state for the most part has broad discretion in determining the payment methodology and payment rate for services. Generally, payment rates must be sufficient to enlist enough providers so that covered services are available at least to the extent that comparable care and services are available to the general population within that geographic area. Providers participating in Medicaid must accept Medicaid payment rates as payment in full. States must make additional payments to qualified hospitals that provide inpatient services to a disproportionate number of Medicaid beneficiaries and to other low-income or uninsured persons under what is known as the disproportionate share hospital (DSH) adjustment. From 1988 to 1991, excessive and inappropriate use of the DSH adjustment resulted in rapidly increasing federal expenditures for Medicaid. Under legislation passed in 1991, 1993, and again within the BBA of 1997, the federal share of payments to DSH hospitals was somewhat limited. However, the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act (BIPA) of 2000 (Public Law 106-554) increased DSH allotments for 2001 and 2002 and made other changes to DSH provisions that resulted in increased costs to the Medicaid program.
States may impose nominal deductibles, coinsurance, or copayments on some Medicaid beneficiaries for certain services. The following Medicaid beneficiaries, however, must be excluded from cost sharing: pregnant women, children under the age of 18, and hospital or nursing home patients who are expected to contribute most of their income to institutional care. In addition, all Medicaid beneficiaries must be exempt from copayments for emergency and family planning services. Under the DRA, new cost sharing and benefit rules provide states with the option of imposing new premiums and increased cost sharing on all Medicaid beneficiaries except for those mentioned above and for terminally ill patients in hospice care. The DRA also established special rules for cost sharing for prescription drugs and for nonemergency services furnished in emergency rooms.
The federal government pays a share of the medical assistance expenditures under each state's Medicaid program. That share, known as the Federal Medical Assistance Percentage (FMAP), is determined annually by a formula that compares the state's average per capita income level with the national income average. States with a higher per capita income level are reimbursed a smaller share of their costs. By law, the FMAP cannot be lower than 50 percent or higher than 83 percent. In fiscal year 2006, the FMAPs varied from 50.0 percent in 12 states to 76.0 percent in Mississippi and averaged 56.7 percent overall. The BBA also permanently raised the FMAP for the District of Columbia from 50.0 percent to 70.0 percent and raised the FMAP for Alaska from 50 percent to 59.8 percent through 2000. The BIPA of 2000 further adjusted Alaska's FMAP to a higher level for fiscal years 2001 to 2005, as did the DRA for fiscal years 2006 and 2007. The Jobs and Growth Tax Relief Reconciliation Act of 2003 (Public Law 108-27), to bring about state fiscal relief in a troubled economy, made three temporary modifications to the states' FMAP calculation: (1) the FMAP for the last two quarters of 2003 equaled the greater of the current law FMAPs for 2002 or 2003; (2) the FMAP for the first three quarters of 2004 equaled the greater of the current law FMAPs for 2003 or 2004; and (3) for the last two quarters of 2003 and first three quarters of 2004, the newly calculated (under 1 and 2 above) FMAP increased by 2.95 percentage points. For children covered through the SCHIP program, the federal government pays states a higher share, or enhanced FMAP, that averages about 70 percent for all states as compared with the general Medicaid average of 56.7 percent.
The federal government also reimburses states for 100 percent of the cost of services provided through facilities of the Indian Health Service, provides financial help to the 12 states that furnish the highest number of emergency services to undocumented aliens, and shares in each state's expenditures for the administration of the Medicaid program. Most administrative costs are matched at 50 percent, although higher percentages are paid for certain activities and functions, such as development of mechanized claims processing systems.
Except for the SCHIP program, the Qualifying Individuals (QI) program (described later), and DSH payments, federal payments to states for medical assistance have no set limit (cap). Rather, the federal government matches (at FMAP rates) state expenditures for the mandatory services, as well as for the optional services that the individual state decides to cover for eligible beneficiaries, and matches (at the appropriate administrative rate) all necessary and proper administrative costs. The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 1999 (as incorporated into Public Law 106-113, the appropriations bill for the District of Columbia for fiscal year 2000) increased the amount that certain states and the territories can spend on DSH and SCHIP payments, respectively. The BIPA set upper payment limits for inpatient and outpatient services provided by certain types of facilities.
Summary and Trends
Medicaid was initially formulated as a medical care extension of federally funded programs providing cash income assistance for the poor, with an emphasis on dependent children and their mothers, the disabled, and the elderly. Over the years, however, Medicaid eligibility has been incrementally expanded beyond its original ties with eligibility for cash programs. Legislation in the late 1980s assured Medicaid coverage to an expanded number of low-income pregnant women and poor children and to some Medicare beneficiaries who are not eligible for any cash assistance program. Legislative changes also focused on increased access, better quality of care, specific benefits, enhanced outreach programs, and fewer limits on services.
In most years since its inception, Medicaid has had very rapid growth in expenditures. This rapid growth has been due primarily to the following factors:
- the increase in size of the Medicaid-covered populations, as a result of federal mandates, population growth, and economic recessions
- the expanded coverage and utilization of services
- the DSH payment program, coupled with its inappropriate use to increase federal payments to states
- the increase in the number of very old and disabled persons requiring extensive acute and long-term health care and various related services
- the results of technological advances to keep a greater number of very low-birth-weight babies and other critically ill or severely injured persons alive and in need of continued extensive and very costly care
- the increase in drug costs and the availability of new expensive drugs
- the increase in payment rates to providers of health care services, when compared with general inflation
As with all health insurance programs, most Medicaid beneficiaries incur relatively small average expenditures per person each year, and a relatively small proportion incurs very large costs. Moreover, the average cost varies substantially by type of beneficiary. National data for 2003, for example, indicate that Medicaid payments for services for 26.8 million children, who constitute 52 percent of all Medicaid beneficiaries, average about $1,550 per child (a relatively small average expenditure per person). Similarly, for 12.6 million adults, who make up 24 percent of beneficiaries, payments average about $2,215 per person. However, certain other specific groups have much larger per-person expenditures. Medicaid payments for services for 4.4 million aged, constituting 8 percent of all Medicaid beneficiaries, average about $13,220 per person; for 8.3 million disabled, who make up 16 percent of beneficiaries, payments average about $12,855 per person. When expenditures for these high- and lower-cost beneficiaries are combined, the 2003 payments to health care vendors for 52.0 million Medicaid beneficiaries average $4,485 per person.
Long-term care is an important provision of Medicaid that will be increasingly utilized as our nation's population ages. The Medicaid program paid for over 41 percent of the total cost of care for persons using nursing facility or home health services in 2003. National data for 2003 show that Medicaid payments for nursing facility services (excluding ICFs/MR) totaled $40.4 billion for more than 1.7 million beneficiaries—an average expenditure of $23,880 per nursing home beneficiary. The national data also show that Medicaid payments for home health services totaled $4.4 billion for more than 1.2 million beneficiaries—an average expenditure of $3,725 per home health care beneficiary. With the percentage of our population who are elderly or disabled increasing faster than that of the younger groups, the need for long-term care is expected to increase.
Another significant development in Medicaid is the growth in managed care as an alternative service delivery concept different from the traditional fee-for-service system. Under managed care systems, HMOs, prepaid health plans (PHPs), or comparable entities agree to provide a specific set of services to Medicaid enrollees, usually in return for a predetermined periodic payment per enrollee. Managed care programs seek to enhance access to quality care in a cost-effective manner. Waivers may provide the states with greater flexibility in the design and implementation of their Medicaid managed care programs. Waiver authority under sections 1915(b) and 1115 of the Social Security Act is an important part of the Medicaid program. Section 1915(b) waivers allow states to develop innovative health care delivery or reimbursement systems. Section 1115 waivers allow statewide health care reform experimental demonstrations to cover uninsured populations and to test new delivery systems without increasing costs. Finally, the BBA provided states with a new option to use managed care. The number of Medicaid beneficiaries enrolled in some form of managed care program is growing rapidly, from 32 percent of enrollees in 1995 to 63 percent in 2005.
More than 52.0 million persons received health care services through the Medicaid program in fiscal year 2003 (the last year for which beneficiary data are available). In fiscal year 2005, total outlays for the Medicaid program (federal and state) were $317.7 billion, including direct payment to providers of $226.2 billion, payments for various premiums (for HMOs, Medicare, etc.) of $58.9 billion, payments to disproportionate share hospitals of $15.6 billion, administrative costs of $15.5 billion, and $1.3 billion for the Vaccines for Children program. Outlays under the SCHIP program in fiscal year 2005 were $7.3 billion. With no changes to either program, expenditures under Medicaid and SCHIP are projected to reach $455.6 billion and $7.4 billion, respectively, by fiscal year 2011.
The Medicaid-Medicare Relationship
Medicare beneficiaries who have low incomes and limited resources may also receive help from the Medicaid program. For such persons who are eligible for full Medicaid coverage, the Medicare health care coverage is supplemented by services that are available under their state's Medicaid program, according to eligibility category. These additional services may include, for example, nursing facility care beyond the 100-day limit covered by Medicare, prescription drugs, eyeglasses, and hearing aids. For persons enrolled in both programs, any services that are covered by Medicare are paid for by the Medicare program before any payments are made by the Medicaid program, since Medicaid is always the payer of last resort.
Certain other Medicare beneficiaries may receive help with Medicare premium and cost-sharing payments through their state Medicaid program. Qualified Medicare Beneficiaries (QMBs) and Specified Low-Income Medicare Beneficiaries (SLMBs) are the best-known categories and the largest in numbers. QMBs are those Medicare beneficiaries who have resources at or below twice the standard allowed under the SSI program and incomes at or below 100 percent of the FPL. For QMBs, Medicaid pays the Hospital Insurance (HI, or Part A) and Supplementary Medical Insurance (SMI, or Part B) premiums and the Medicare coinsurance and deductibles, subject to limits that states may impose on payment rates. SLMBs are Medicare beneficiaries with resources like the QMBs but with incomes that are higher, though still less than 120 percent of the FPL. For SLMBs, the Medicaid program pays only the Part B premiums. A third category of Medicare beneficiaries who may receive help consists of disabled and working individuals. According to the Medicare law, disabled and working individuals who previously qualified for Medicare because of disability, but who lost entitlement because of their return to work (despite the disability), are allowed to purchase Medicare Part A and Part B. If these persons have incomes below 200 percent of the FPL but do not meet any other Medicaid assistance category, they may qualify to have Medicaid pay their Part A premiums as Qualified Disabled and Working Individuals (QDWIs).
For Medicare beneficiaries with incomes above 120 percent and less than 135 percent of the FPL, states receive a capped allotment of federal funds for payment of Medicare Part B premiums. These beneficiaries are known as Qualifying Individuals (QIs). Unlike the QMBs and SLMBs, who may be eligible for other Medicaid benefits in addition to their QMB/SLMB benefits, the QIs cannot be otherwise eligible for medical assistance under a state plan. The QI benefit is 100 percent federally funded, up to the state's allotment. The QI program was established by the BBA for fiscal years 1998–2002 and has been extended several times. The current extension will expire at the end of fiscal year 2007.
The Centers for Medicare & Medicaid Services (CMS) estimates that in 2005 Medicaid provided some level of supplemental health coverage for about 6.8 million Medicare beneficiaries.
Starting January 2006, a new Medicare prescription drug benefit provides drug coverage for Medicare beneficiaries, including those who also receive coverage from Medicaid. In addition, individuals eligible for Medicare and Medicaid receive the low-income subsidy for the Medicare drug plan premium and assistance with cost sharing for prescriptions. Medicaid no longer provides drug benefits for Medicare beneficiaries.
Since the Medicare drug benefit and low-income subsidy replace a portion of state Medicaid expenditures for drugs, states will see a reduction in Medicaid expenditures. To offset this reduction, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (Public Law 108-173) requires each state to make a monthly payment to Medicare representing a percentage of the projected reduction. For 2006, this payment was 90 percent of the projected 2006 reduction in state spending. After 2006, the percentage will decrease by 1 2/3 percent per year to 75 percent for 2014 and later.
Note: Medicaid data are based on the projections of the Mid-Session Review of the President's Fiscal Year 2007 Budget and are consistent with data received from the states on Forms CMS-2082, MSIS, CMS-37, and CMS-64.
