If you or someone in your family relies on Medicaid -- or if you have Medicare and Medicaid both, which applies to about 12 million Americans -- 2026 brought a set of changes that are worth understanding clearly. The headlines have been big and sometimes alarming. The actual situation is more nuanced, but the practical effects on real people are real.
Here is an honest breakdown of what changed, who is affected, and what to watch for.
The One Big Beautiful Bill Act: What It Did
In July 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. Among a wide range of policy changes, it made several significant modifications to Medicaid. The Kaiser Family Foundation and the American Medical Association have both published detailed analyses of the law's health coverage implications. The Congressional Budget Office projected that over time, the combined changes could result in millions of additional Americans without health coverage.
For the purposes of this article, I want to focus on the changes most likely to affect seniors and people approaching Medicare age, not the full sweep of Medicaid policy.
Work Requirements: What They Are and Who They Apply To
The OBBBA requires states to implement what are officially called "community engagement requirements" -- in practice, this means Medicaid eligibility for certain adults is now conditioned on working, participating in job training, volunteering, or other approved activities for a minimum number of hours per month.
The requirements do not apply to everyone. People who are elderly, disabled, pregnant, or caring for a young child are generally exempt. The requirements target able-bodied adults between 18 and 64 who receive Medicaid through the ACA expansion.
According to KFF, Nebraska became the first state to begin enforcing work requirements under this law, starting May 1, 2026. Other states are at various stages of implementation, with a federal deadline set for January 2027.
If you are approaching 65: If you currently have Medicaid and are turning 65 soon, you will transition to Medicare. The work requirements apply to the ACA expansion population, not to elderly beneficiaries. But the transition process itself requires attention -- contact your state Medicaid office and Social Security well before your 65th birthday to coordinate coverage.
More Frequent Eligibility Checks
One of the changes with the most immediate practical impact is the shift from annual to semi-annual eligibility redeterminations for certain Medicaid beneficiaries. States are now required to check eligibility every six months rather than once a year for some populations.
Why does this matter? Because eligibility reviews generate paperwork, and paperwork sometimes gets lost, mailed to old addresses, or not responded to in time. During the post-pandemic Medicaid "unwinding" process in 2023 and 2024, millions of people lost Medicaid coverage -- many of them still eligible -- simply because the administrative process broke down on one side or the other.
More frequent reviews mean more opportunities for that to happen. If you or a family member is on Medicaid, the single most important protective step you can take is making sure your current mailing address, phone number, and email are on file with your state Medicaid office. Most states allow online updates through their Medicaid portal. Do this now, not when a renewal notice arrives.
Reduced Federal Funding for Expansion States
Under the Affordable Care Act, states that expanded Medicaid received enhanced federal matching funds -- the federal government covered a higher percentage of expansion costs than non-expansion costs. The OBBBA reduces the federal match rate for expansion states, meaning those states must now cover a larger share of expansion costs themselves.
The practical effect varies by state. Some states have signaled they will find ways to maintain current coverage levels. Others are facing budget pressures that could eventually affect benefits, provider reimbursement rates, or eligibility thresholds. This is a situation to watch over the next year to two years, particularly in states with tight budgets.
What This Means for Dual Eligibles
People who have both Medicare and Medicaid -- called dual eligibles -- deserve special attention here. For this population, Medicaid is not just healthcare coverage; it often pays Medicare premiums, deductibles, and cost-sharing that would otherwise be significant out-of-pocket expenses.
The OBBBA's changes primarily target the ACA expansion population, which skews younger. Most elderly dual eligibles qualify for Medicaid through different pathways -- generally by meeting income and asset thresholds for low-income seniors -- and are less directly affected by the work requirements specifically. However, the broader budget pressures on state Medicaid programs could eventually affect the benefits and assistance available to dual eligibles over time.
If you are a dual eligible and your financial or living situation changes, report it to your state Medicaid office promptly. Gaps in Medicaid can mean losing the cost-sharing protection that makes your healthcare affordable.
Getting Help Navigating This
Medicaid rules are administered at the state level within federal guidelines, which means the specific impact of these changes varies considerably depending on where you live. The best resource for understanding how your state is implementing the new requirements is your state's Medicaid agency directly.
For unbiased guidance on how Medicaid changes interact with your Medicare coverage, your state's SHIP (State Health Insurance Assistance Program) counselors are also a good starting point. They are free, do not work on commission, and deal with exactly these intersection questions regularly.
Bottom Line
The 2026 Medicaid changes -- work requirements, more frequent eligibility checks, and reduced federal funding for expansion -- primarily affect the ACA expansion population rather than elderly Medicare-Medicaid dual eligibles directly. But the administrative effects (more frequent renewals, potential state-level benefit changes) can affect seniors too. Keep your contact information current with your state Medicaid office and check in with your SHIP counselor if you have questions about how these changes affect your specific situation.
