Medicaid applications filed on or after Jan. 1, 2027 can reach back only two months for most people 65 and older, down from three. Adults covered through Medicaid expansion get one month. The cut comes from Section 71112 of H.R. 1, Public Law 119-21, the 2025 budget law, and it changes how far back Medicaid will pay for care received before a person applied.
Retroactive coverage is the rule that lets Medicaid pay bills from the months before the application month, as long as the person met the program’s requirements then. Families often use it after a hospital stay or a move into a nursing home, when the application is filed weeks after the care began. Each month trimmed from the reach is a month of bills that no longer qualifies.
Anyone planning a Medicaid application for a parent, a spouse or themselves has a date to weigh: an application filed in December falls under the three-month rule, and one filed in January falls under the shorter one. The state Medicaid office handles the filing and sets the application date, so the filing date on the paperwork is the one that counts.

Two months for most applicants and one month for expansion adults
Justice in Aging, a legal advocacy group for older adults, describes the new limit as two months before the application month for most applicants, including people 65 and older and people with disabilities. For adults enrolled through Medicaid expansion, the limit drops to one month before the application month. Under the prior rule, coverage could reach back up to three months.
California’s Department of Health Care Services put the same split into a March 2026 county letter. It says retroactive coverage is limited to one month for the adult expansion group and two months for all other groups. The letter cites Section 71112 of H.R. 1, Public Law 119-21.
The month of application is still the starting line
One piece of the old system does not change. Under 42 C.F.R. 435.915, Medicaid coverage is counted from the application month, not the month an application is approved. Justice in Aging notes that retroactive coverage counts back from that application month.
In practice, a 67-year-old who enters a nursing home in January and applies in March 2027 can have bills from January and February considered, if Medicaid eligibility was met in those months. The same person applying in March 2026 could have had December bills considered too. The one month the law removes is the one furthest from the application.
Applications filed before Jan. 1 keep the three-month reach
California’s letter says applications with an application date before Jan. 1, 2027 must still be decided under the current policy, which allows up to three months. Washington’s Health Care Authority publishes the same schedule: one month for adults ages 19 to 64 and two months for all other programs, starting Jan. 1, 2027, with the current three-month rule found in state rule WAC 182-504-0005.
The state letters are guidance for those states’ own programs. California says its letter is preliminary and may change, so the details can vary where a state has added its own rules. The federal limits of two months and one month are the federal ceiling every state faces from January.
What the shorter reach means for care bills
A Medicaid application that is ready on the day care begins loses nothing under the new rule, because the application month itself is covered. The risk sits with applications that wait. A family that spends several months sorting out paperwork or assets before filing will find fewer of the early bills eligible, while the rest remain the family’s to pay.
Justice in Aging says the rollback hits adults under 65 hardest, since expansion coverage is the group cut to one month. For older adults, the change is smaller on paper, one month, but a nursing-home month is a large bill.
Is a Medicaid application for a parent or spouse waiting past the end of the year?
A shorter retroactive window raises the cost of a late start. Medicaid also looks at what a person gave away, and families who file after a fall or a diagnosis often learn about both rules at once.
“Protect Your Savings From Care Costs” is a 10-page guide that covers Medicaid’s 5-year look-back before anything is given away, and what Medicare pays for nursing care and what it won’t. Its 2026 figures page shows how the at-home spouse is protected, with the numbers set out for a couple.
