There is no single provision in federal law that concisely sets forth the entitlement to coverage. Judicial interpretations of the federal Medicaid law have generally grounded the entitlement in section 1902(a) (8), Title XIX of the Social Security Act, 42 USC.1396(a)(8).

By contrast, smaller public coverage programs (for example, separate, non-Medicaid, SCHIP programs) and other public programs that help pay for medical services (such as the Ryan White program, the Maternal and Child Health block grant program, and various pharmacy benefit programs) do not extend a legal entitlement to coverage. SmithB. and RosenbaumS., State SCHIP Design and the Right to Coverage, Center for Health Services Research (Washington, D.C.: George Washington University, 2001). As a result, the number of people provided services under these programs can be capped, waiting lists can be formed, and enrollment can be closed for budget or other reasons.

For example, federal program data show that there were 13 million beneficiaries in 1968; program data for 2001 show enrollment above 47 million. The Congressional Budget Office projects that enrollment will reach 52.4 million in 2004. Health Care Financing Administration (HCFA) data for 1968 provided by the Kaiser Commission on Medicaid and the Uninsured; 2001 data from Georgetown University Health Policy Institute's analysis of the 2001 Medicaid Statistical Information System (MSIS) data; 2004 data from Congressional Budget Office's March 2004 Medicaid Baseline.
This is based on the “regular” matching rates in effect in fiscal year 2004. Enhanced rates, which ended as of June 30, 2004, lowered state contributions to twenty to forty-seven percent. The federal matching rate varies by state, with poorer states having a lower state spending requirement.

As discussed above, originally, Medicaid eligibility was linked to welfare eligibility and childless adults did not fit under either of the two major welfare programs — the Aid to Families with Dependent Children program and the Aid to Aged, Blind and Disabled program (the precursor to the federal Supplemental Security Income, or SSI, program). Under the law, states can cover adults who are pregnant, living with a child, elderly or disabled.
56.
This imbalance is mirrored at the Federal level in the consideration of legislation to require States to offer home- and community-based care. The Medicaid Community-based Attendant Services and Support Act (Mi-CASSA) has been introduced and re-introduced in the Congress for many years, but its consideration has been haunted by cost-estimates that are predicated on an assumption that more people would use such care than use institutional services. See GlazierR., “The Re-invention of Personal Assistance Services,”Disability Studies Quarterly21, no. 2 (2001), available at <http://63.240.118.142/_articles_html/2001/Spring/dsq_2001_Spring_12.html> (last visited July 1, 2004).

For example, in 1997, federal law was amended to provide states more authority to set rates for institutional providers (nursing homes and hospitals) and to require Medicaid beneficiaries, under certain conditions, to enroll in managed care. In that same year, states were allowed new options to presumptively enroll children in Medicaid and to keep children enrolled for up to twelve months regardless of changes in financial circumstances; See Yellowbook, supra note 3.

Since August 2002, the Bush Administration has released three major waiver initiatives: the Health Insurance Flexibility and Accountability (HIFA) initiative, see, Centers for Medicaid and Medicare Services Website, at <http://www.cms.hhs.gov/hifa/> (last visited June 24, 2004); Pharmacy Plus, at <http://www.cms.hhs.gov/medicaid/1115/pharmacyplus.asp> (last visited June 24, 2004); and Independent Plus, at <http://www.cms.hhs.gov/independenceplus/> (last visited June 24, 2004). Each encourages states to submit section 1115 demonstration waiver requests that meet the guidelines set forth in these initiatives. The Administration has consistently cited waivers as a key policy tool to provide states greater programmatic flexibility; See, U.S. Department of Health and Human Services, News Releases, Statement By Tommy G.

For example, Oregon, has adopted a series of very deep reductions in coverage; it eliminated the portion of its program that covered people impoverished by their medical expenses and instituted new premium policies for poor adults that have caused about half of those adults to drop out of the program, See Oregon Health Research & Evaluation Collaborative Website, at <http://www.ohpr.state.or.us/OHREC%20welcome2.htm> (last visited June 24, 2004).

All of the presidential candidates who had a broad-based health care reform proposal included a substantial role for Medicaid (or a program with similar elements), with some anticipating a considerably expanded role as compared to today, see, “Side-by-Side Summary of Presidential Candidates' Proposals for Expanding Health Insurance Coverage,”Kaiser Commission on Medicaid and the Uninsured (Washington, D.C.: Kaiser Family Foundation, 2003); CollinsS.R.DavisK., and LambrewJ., “Health Care Reform Returns to the National Agenda: The 2004 Presidential Candidates' Proposals,”Commonwealth Fund671 (2004): 7–10.

73.
Tax credits have been advanced as one possible way to help low-income people afford private coverage, and refundable tax credits have been proposed as a way to extend this subsidy to the millions of Americans whose incomes are too low to owe income tax (or to owe an amount of tax that would exceed the potential subsidy amount). A number of structural issues would have to be resolved for a refundable tax credit system to work well as a way to finance health insurance for low-income people; see BlumbergL., Health Insurance Tax Credits: Potential for Expanding Coverage (Washington, D.C.: The Urban Institute, 2001). To date, the refundable tax credit created under the recent Trade Act has had limited take up, in part due these structural problems; as of the end of 2003, only about 3.6 percent of the workers who were potentially eligible had enrolled in the advance credit.

Some new tools could help states contain Medicaid costs without compromising the quality of care; for example, disclosure to state Medicaid agencies of drug pricing that would allow states to improve their ability to set drug prices. Some changes would need to occur within the Medicaid program while other measures go beyond Medicaid and would help Medicaid as well as other payers contain costs.

“Churning” refers to loss of coverage, often due to administrative requirements, followed by re-enrollment in the program. This not only disrupts coverage and care, but also results in added costs.

States should, of course, be permitted to adopt procedures that assure program integrity. States have generally found that streamlined processes do not interfere with states' ability to take a variety of measures (including data matches, using information from other state programs, and random audits) to assure that people who are enrolled are eligible for the program.

Research has repeatedly shown that premiums and cost sharing, if set too high, will deter low-income people from enrolling in coverage and accessing necessary care; See, HudmanJ. and O'MalleyM., “Health Insurance Premiums and Cost-Sharing: Findings from the Research on Low-Income Populations,”Kaiser Commission on Medicaid and the Uninsured (Washington, D.C.: Kaiser Family Foundation, 2003); KuL., Charging the Poor More for Health Care: Cost-Sharing in Medicaid, (Washington, D.C.: Center on Budget and Policy Priorities, 2003); TamblynR., “Adverse Events Associated with Prescription Drug Cost-Sharing among Poor and Elderly Persons,”Journal of the American Medical Association285, no. 4 (2001): 421–429; HRSA State Planning Grant Consultant Team, Income Adequacy and Affordability of Health Insurance in Washington State (University of Washington Health Policy Analysis Program, Rutgers University Center for State Health Policy, RAND, William M. Mercer, Inc., The Foundation for Health Care Quality, 2002). The recent experience in Oregon where more than half of the poor adults who were subject to premiums dropped out of the program shows that even relatively modest premiums (in this case, premiums ranged from six dollars to twenty a month) can be too high for poor people; McConnellJ. and WallaceN., Impact of Premium Changes in the Oregon Health Plan (February 2004), Oregon Health Research & Evaluation Collaborative, at <http://www.ohpr.state.or.us/OHREC%20welcome2_files/Reports%20and%20Briefs/Impacts%20of%20Premiums%20-%20FINAL.pdf> (last visited July 1, 2004).
