A landmark federal agreement to dramatically reduce the cost of GLP-1 medications and open the door to Medicare coverage has generated cautious optimism among millions of older adults living with obesity. But even as the White House frames the deal as a breakthrough, health equity advocates warn that disparities in access could deepen before they improve, particularly for communities already carrying the heaviest burden of chronic disease.

The announcement, released in November 2025 through negotiated agreements with Eli Lilly and Novo Nordisk, marks the first time Medicare has established a pathway to cover GLP-1 drugs specifically for obesity. Until now, federal law prevented Medicare from covering weight-loss medications, limiting reimbursement to cases in which the drugs were used for other approved conditions such as diabetes or cardiovascular disease. Under the new pricing structure, Medicare will be able to purchase GLP-1 medications for approximately $245 per month, with beneficiaries in participating plans paying no more than $50 out of pocket. Lilly stated publicly that coverage could begin as early as April 1, 2026, pending federal guidance.

The shift comes amid growing evidence about the medical value of GLP-1 therapies. Recent studies published in journals including The Lancet and The New England Journal of Medicine have shown significant reductions in cardiovascular risk, diabetes progression, and all-cause mortality among certain patients using GLP-1 medications. Public health leaders, including researchers at the National Institutes of Health, have increasingly emphasized that obesity is a chronic, relapsing disease influenced by biology, environment, and inequities in access to care, rather than individual choice.

Despite the milestone, however, the policy’s implementation will not be immediate or uniform. Federal officials have confirmed that Medicare will rely on two demonstration projects to begin offering coverage. The first is expected to launch as early as spring 2026 and would allow participating Medicare Advantage and Part D plans to begin covering GLP-1s without waiting for the 2027 plan-year cycle. Participation in this initial demonstration will be voluntary, which analysts say is likely to create geographic and insurer-by-insurer disparities in availability. A larger model from the Center for Medicare and Medicaid Innovation is planned for 2027 and is expected to standardize coverage among participating plans, though insurers must still opt in. Both demonstrations preserve the negotiated price and the maximum $50 monthly copay.

Uneven State Decisions Could Widen Medicaid Gaps

While the Medicare timeline is becoming clearer, the future of GLP-1 access in Medicaid remains uncertain. Under the new agreement, states may purchase the medications at the same reduced federal price, but coverage decisions remain voluntary and subject to state-by-state policy debates. Medicaid currently covers weight-loss medications inconsistently across the country, and early advocacy statements suggest that the new flexibility may lead to greater variation rather than alignment. States with historically restrictive Medicaid formularies or limited budgets may continue to limit coverage for obesity treatment, even as research shows that low-income individuals and communities of color face higher rates of obesity-related illness. According to the Centers for Disease Control and Prevention, Black and Latino adults experience disproportionately higher rates of obesity and related chronic conditions such as hypertension and diabetes, raising concerns that unequal implementation could reinforce existing disparities.

Patient advocates say the mixed landscape has created a blend of hope and hesitation. National organizations representing older adults have welcomed the announcement but caution that beneficiaries will need to monitor their coverage closely, particularly during the first year of the demonstration. Because insurers must opt in, access may depend on the type of plan a person holds, their geographic region, and whether their insurer is prepared to absorb the administrative changes required to offer coverage in 2026. Health policy researchers note that some beneficiaries may ultimately need to switch plans to obtain coverage, an option that could be limited by enrollment windows.

The Medicare announcement follows a period of intense scrutiny of GLP-1 pricing and accessibility. In 2024 and 2025, congressional committees held hearings examining the costs of obesity care, and federal watchdogs analyzed how high GLP-1 prices were affecting state Medicaid budgets. Bipartisan pressure has grown as new clinical data show not only weight-loss benefits but also major improvements in cardiovascular outcomes. In November 2023, the American Heart Association highlighted GLP-1s as a promising tool in reducing deaths from heart disease, the nation’s leading cause of mortality.

Experts say the administration’s new agreement reflects a broader shift in how policymakers understand obesity. Rather than viewing obesity solely through behavioral or lifestyle frameworks, the new policy acknowledges the biological, systemic, and environmental contributors that shape health outcomes. Yet they also caution that execution will determine whether the policy becomes a driver of equity or a source of further fragmentation. States must decide whether to cover the drugs in Medicaid, insurers must choose whether to participate in demonstrations, and regulators must finalize guidance that determines how plans will operationalize the benefit.

Officials at the Centers for Medicare and Medicaid Services are expected to release detailed instructions early in 2026. Until then, beneficiaries, clinicians, and advocates will be watching closely to see which insurers opt in and how states approach Medicaid decisions. For now, the federal agreement marks a turning point in obesity care. Whether it ultimately reduces disparities or reinforces them will depend on decisions made in the months ahead, but many patients say it is the first time they have seen a clear path toward meaningful, long-term access.
