The Centers for Medicare & Medicaid Services has told every state Medicaid agency, plus the District of Columbia, that a specific group of enrollees will soon have to prove their eligibility twice as often. Under guidance issued in March 2026, adults who qualify through Medicaid’s expansion group move from a 12-month renewal cycle to a six-month cycle, starting with any renewal a state schedules on or after January 1, 2027. For adults in their fifties and early sixties who rely on expansion Medicaid as a bridge to Medicare, the switch means twice the paperwork and twice the risk of a coverage gap if a renewal form goes unanswered.
A Statutory Mandate From the 2025 Tax Law
The change traces back to Section 71107 of the “Working Families Tax Cut” legislation, the name federal officials use for the tax and spending law signed on July 4, 2025. That provision amends section 1902(e)(14) of the Social Security Act to require states to complete eligibility redeterminations once every six months, rather than once every 12, for most adults enrolled in the Medicaid group created by the Affordable Care Act’s expansion option. The Centers for Medicare & Medicaid Services spelled out the operational details in a State Medicaid Director letter, numbered SMD #26-001 and dated March 6, 2026, addressed to all 50 states and the District of Columbia.
The letter walks through a hypothetical to show how the new cycle plays out. In the example, a beneficiary who applies for Medicaid in June 2027 and is found eligible for the expansion group gets a six-month eligibility period running through late November 2027; if he remains eligible at his next renewal, the state grants him another six months rather than a full year. That pattern repeats for anyone newly determined eligible in the group after January 1, 2027.

The Adult Expansion Group and Its Exemptions
According to the CMS letter, the six-month requirement applies to people enrolled under a state plan in the Medicaid adult group described at section 1902(a)(10)(A)(i)(VIII) of the Social Security Act, plus people who get equivalent coverage through a section 1115 demonstration waiver. It does not apply to certain American Indians and Alaska Natives, who stay on 12-month renewals under a separate exemption written into the same statute. It also leaves untouched every other Medicaid eligibility category, including children, pregnant women, and people who qualify through non-income-based pathways tied to age or disability, all of whom keep their current 12-month renewal schedule.
The letter flags a related change arriving the same day: beginning January 1, 2027, many people in the newly affected group will also have to demonstrate compliance with Medicaid community engagement requirements created by a separate section of the same 2025 law. States will fold that documentation into the same renewal process, adding another layer to what a beneficiary has to submit every six months.
Two State Paths for Shifting the Renewal Clock
Because the statute’s effective-date language can be read two ways, the letter gives states a choice for beneficiaries already enrolled in a 12-month eligibility period as 2027 begins. Under what CMS calls Option 1, a state can shorten those existing periods and move a beneficiary’s renewal initiation date up, but never earlier than January 1, 2027, in practice January 4, 2027, the first business day of the year. Under Option 2, a state can leave an already-scheduled 2027 renewal date untouched and simply grant a six-month period, instead of 12, the next time that beneficiary’s renewal comes due. States choosing Option 1 are, in CMS’s own terms, shortening someone’s coverage period, an action that requires at least 10 days’ advance notice and fair hearing rights before it takes effect.
The March 2027 Deadline for State Plan Amendments
States that cover the expansion group through their Medicaid state plan, rather than only through a waiver, must formally attest to the new six-month cycle by submitting a state plan amendment through a CMS filing system called MACPro. The March 2026 letter sets a submission deadline of March 31, 2027, and notes that CMS is still building the specific reviewable unit states will use to file that amendment, with release targeted for the second half of 2026. States that cover the group only through a section 1115 waiver are told to work directly with their demonstration project officer instead of filing a state plan amendment.
The Medicare-Side Program the Same Agency Handles
The state Medicaid agencies that will run expansion renewals every six months are the same agencies that take applications for the Medicare Savings Programs, which cover the Part B premium for retirees under the income limits. Adults who use expansion Medicaid as a bridge to 65 can file paperwork with that office for years without ever being told the Medicare-side program exists. It is opt-in, and a renewal notice does not mention it.
That program and ten others are set out in a 63-page guide, with a 50-state directory of the offices that take the applications and the documents each one asks for.
