Medicare eligibility for immigrants is shrinking to four groups, and the Social Security Administration has begun telling current enrollees who fall outside them that their coverage may end on Feb. 1, 2027. In a Nov. 10 letter to advocates, SSA said that this week it would start applying the new rules in Section 71201 of the 2025 reconciliation law (Public Law 119-21) to new Medicare applications and notify beneficiaries whose eligibility it cannot confirm.
The law, enacted July 4, 2025, ends a long-standing rule under which most noncitizens who were lawfully present and met the work or residence requirements could get Medicare. Going forward, SSA says, a person may be entitled to or enrolled in Medicare only as a U.S. citizen or national, a lawful permanent resident, a Cuban-Haitian entrant, or a citizen of Micronesia, the Marshall Islands or Palau lawfully residing in the United States under a Compact of Free Association. The change does not touch Social Security retirement or disability checks, the agency said.
Who loses Medicare eligibility
Read against that list, the people who lose access are lawfully present noncitizens without a green card: refugees and asylees who have not yet adjusted status, Temporary Protected Status holders, humanitarian parolees and people granted withholding of removal, among others. Some have worked and paid Medicare payroll taxes for years. A work permit does not help on its own; SSA lists Form I-766 only as one kind of evidence of immigration status, not as a qualifying status.
The timing makes USCIS a central player. A refugee who has applied for a green card but is still waiting stays outside the eligible groups until the I-485 is approved, and USCIS’s hold on many refugee green card cases is now being challenged in a federal class action. For those beneficiaries, whether Medicare survives into February may depend less on SSA than on how fast an adjudicator in another agency clears a file.
Eligible people will get letters too
The notices go to anyone whose eligibility SSA “cannot confirm,” which is broader than the people the law excludes. SSA’s records may not reflect a later naturalization or a green card approved after a person first enrolled, so citizens and permanent residents may receive a letter they must answer. Medicare is sending its own warning on pink paper, the “Medicare disenrollment warning notice” (CMS Product No. 12238), which Medicare.gov says will arrive in December 2026 and which states that unconfirmed coverage “will end February 1, 2027.”
SSA’s instructions are concrete. Beneficiaries can upload proof through a my Social Security account using “Upload Documents,” take documents to a local office, or call 1-844-507-7131. Acceptable evidence includes a U.S. passport, a Certificate of Naturalization, a Permanent Resident Card (Form I-551), an I-94 record or an employment authorization document. Coverage generally stays in effect through Jan. 31, 2027. Anyone who receives a decision letter they believe is wrong must appeal in writing within 60 days, using SSA’s online Non-Medical Appeal form or Form SSA-561-U2, Request for Reconsideration.
Neither SSA nor CMS has published how many current enrollees will be cut off. When the bill passed, the Congressional Budget Office projected that the Medicare provision would leave about 100,000 more people uninsured in 2034 and cut federal spending by $5.1 billion, according to a KFF summary of CBO’s estimates. Those are long-range budget projections, not a count of who will lose coverage in February.
What happens after Feb. 1
People who later obtain an eligible status, most commonly a green card, may apply for Medicare at that point, subject to the program’s other requirements, SSA said. The practical risk is the gap in between. Medicare enrollment runs on fixed windows, so a beneficiary dropped in February who gets a green card in, say, June may face questions about when coverage can restart that the agencies have not yet answered publicly.
The Medicare cutoff is the latest in a run of status-verification requirements tied to the same law and related rules, including ACA subsidy verification, state Medicaid terminations and HUD’s final mixed-status housing rule. Each turns on the same question: whether a federal database can match a person’s current status. Errors in that match, rather than the eligibility rules themselves, are where most disputes are likely to arise.
Key dates for Medicare enrollees
- Now: SSA letters to beneficiaries whose eligibility it cannot confirm, and new rules applied to new applications.
- December 2026: Medicare’s pink disenrollment warning notices.
- Jan. 31, 2027: last day of coverage for those who have not established eligibility.
- Feb. 1, 2027: terminations take effect; the 60-day written appeal window runs from receipt of each decision letter.
