The One Big Beautiful Bill Act (OBBBA), Public Law 119-21, dominated 2025 and 2026 headlines mostly for its Medicaid and ACA marketplace changes, but it also touches Medicare in five specific ways. None of them remove a covered service from Original Medicare Part A or Part B, yet several change who can enroll, how much low-income beneficiaries get in assistance, and how much providers get paid in 2026.
Five Medicare-specific provisions of the 2026 law matter most: the temporary physician pay bump, the immigrant eligibility restriction, the Medicare Savings Program freeze, the PAYGO sequester scare and its 2026 waiver, and what to do if you're personally affected.

Coverage Breakdown
| Medicare Provision | What Changed | 2026 Status | Effective Date |
|---|---|---|---|
| Medicare Physician Fee Schedule (Part B) | One-year 2.5% payment increase to offset a scheduled formula cut | Temporary increase | January 1 to December 31, 2026 |
| Medicare eligibility by immigration status | Refugees, asylees, TPS holders, and other lawfully present immigrants lose new-enrollment eligibility | Eligibility restricted | New enrollment restricted July 4, 2025; current beneficiaries disenrolled January 1, 2027 |
| Medicare Savings Programs (QMB, SLMB, QI) | Nine-year freeze on CMS rules that would have simplified enrollment for low-income beneficiaries | Improvements frozen | 2026 through 2034 |
| Part D drug price negotiation (IRA) | Orphan drugs for rare diseases are exempted from Medicare's negotiation authority | Negotiation scope narrowed | Ongoing, applies to the 2026 negotiation cycle |
| Nursing home minimum staffing rule | The 2024 CMS staffing mandate for skilled nursing facilities is delayed | Delayed to 2035 | Delayed from a 2026 phase-in to January 1, 2035 |
| PAYGO 4% Medicare sequester | OBBBA's deficit impact triggered an automatic 4% provider payment cut under Statutory PAYGO | Waived for 2026 only | Waived November 12, 2025 through the end of 2026; the separate 2% BCA sequester continues |
The 4% PAYGO sequester and the 2% Budget Control Act sequester are two different mechanisms. Congress waived only the new 4% PAYGO cut for 2026 in a stopgap funding bill; the permanent 2% BCA sequester on Medicare provider payments, in place since 2013, was not affected and still applies in 2026.

Direct Answer: Does the Bill Cut Medicare Benefits?
It depends. The One Big Beautiful Bill Act, signed July 4, 2025, does not cut Medicare benefits for most enrollees, but it restricts Medicare eligibility for certain immigrants starting January 2027, freezes improvements to Medicare Savings Programs for nine years, and originally triggered a 4% PAYGO sequester that Congress waived for 2026 only. A temporary 2.5% Medicare physician pay increase also took effect in 2026.
What Is the One Big Beautiful Bill Act?
The One Big Beautiful Bill Act, formally Public Law 119-21, is the budget reconciliation law President Trump signed on July 4, 2025. It combined roughly $4.5 trillion in tax cuts with more than $1 trillion in health program reductions, most of them aimed at Medicaid and ACA marketplace subsidies rather than Original Medicare. Medicare beneficiaries feel the law mainly through five specific mechanisms rather than a direct benefit cut.
- Medicare Physician Fee Schedule: a temporary 2.5% payment increase for 2026 only.
- Immigration-based eligibility: Original Medicare enrollment restricted to citizens, green card holders, and a few other categories, with disenrollment of current beneficiaries effective January 1, 2027.
- Medicare Savings Programs: a nine-year freeze on CMS rules that would have simplified QMB, SLMB, and QI enrollment.
- Medicare Part D drug price negotiation: orphan drugs for rare diseases are now exempt from Inflation Reduction Act negotiation.
- Nursing home staffing rule: the federal minimum staffing mandate for skilled nursing facilities is delayed to 2035.
Medicare Physician Payments Get a Temporary 2.5% Boost in 2026
Before the law passed, Medicare Part B physician payments were scheduled for a formula-driven cut in 2026 under the existing Medicare Physician Fee Schedule methodology. The One Big Beautiful Bill Act authorized a one-year 2.5% payment increase instead, applying to Original Medicare Part B physician claims and indirectly influencing the rates many Medicare Advantage plans negotiate with in-network providers.
The increase is temporary and expires after December 31, 2026, unless Congress passes new legislation to extend it. It does not change the standard 2026 Part B monthly premium ($202.90) or the 2026 Part B annual deductible ($283), which are set through a separate CMS actuarial formula each fall.
Medicare Eligibility Restrictions for Immigrants Start January 2027
As of July 4, 2025, new enrollment in Original Medicare Part A and Part B is limited to U.S. citizens, lawful permanent residents (green card holders), Cuban and Haitian entrants, and individuals lawfully residing under a Compact of Free Association. This is a narrower list than the immigration statuses Medicare previously recognized.
People already enrolled in Medicare under a now-excluded status, such as refugees, asylees, Temporary Protected Status holders, trafficking survivors, domestic violence survivors, and humanitarian parolees, keep coverage temporarily. CMS must identify and notify them by July 2026, and their Medicare coverage ends effective January 1, 2027. The Center for Medicare Advocacy estimates about 100,000 lawfully present immigrant seniors will lose Medicare this way, many of whom paid Medicare payroll taxes for decades.
| Immigration Status | Medicare Eligibility |
|---|---|
| U.S. citizens | Full eligibility, unchanged |
| Lawful permanent residents (green card holders) | Full eligibility, unchanged |
| Cuban and Haitian entrants | Full eligibility, unchanged |
| Compact of Free Association (COFA) migrants | Full eligibility, unchanged |
| Refugees and people granted asylum | Lose eligibility; enrolled beneficiaries disenrolled January 1, 2027 |
| Temporary Protected Status (TPS) holders | Lose eligibility; enrolled beneficiaries disenrolled January 1, 2027 |
| Trafficking and domestic violence survivors | Lose eligibility; enrolled beneficiaries disenrolled January 1, 2027 |
| Humanitarian parolees | Lose eligibility; enrolled beneficiaries disenrolled January 1, 2027 |
The restriction on new enrollment applies as of July 4, 2025. Disenrollment of current beneficiaries in excluded categories is effective January 1, 2027, after a CMS notification process required by July 2026.
