Medicaid is moving adults in the expansion group from yearly renewals to renewals every six months. The Centers for Medicare & Medicaid Services says the change applies beginning with renewals scheduled on or after January 1, 2027. A second change in the same law limits how far back coverage can reach for a new application to one month.

Who has to renew every six months?

The six-month cycle is for the Medicaid adult group, the people covered under the expansion. A CMS slide deck from April 2026, issued with State Medicaid Director Letter #26-001, says it covers almost all people in that group whose eligibility is based on income, including those covered only through a state waiver that gives equivalent coverage to every adult in the group.

Several groups are left out. Certain American Indians and Alaska Natives are exempt. So are people in other income-based groups, people in groups not based on income, and residents of the territories. The change comes from section 71107 of Public Law 119-21.

What was the rule before, and when does it change?

CMS says current rules require renewals every 12 months. For income-based groups, states may not check eligibility more often than once every 12 months. The new law lifts that for the adult group, so a state must complete a renewal about every six months.

People already in a 12-month period on January 1, 2027 do not all switch at once. CMS gave states two options. A state can reschedule renewals so periods run as close to six months as feasible, which could mean a large number of renewals starting in January 2027. Or it can let the 12-month period run out and begin the six-month period after the renewal already scheduled for 2027.

Anyone moving from a 12-month period to a six-month one must get at least 10 days’ advance notice and the right to a fair hearing. Renewals are individual, so a state may not shorten or extend one person’s period to match another household member.

For adults on expansion Medicaid asking how often proof will be needed, the answer is every six months, starting with the first renewal scheduled in 2027. The state sends the notice. CMS says states must first try to confirm eligibility from data it already has, send a prepopulated renewal form if needed, and allow at least 30 days to respond. Adults who get a form should treat that 30-day window as the working deadline and watch the mail and any online account closely.

How far back does a new application reach?

Section 71112 of the same law shortens retroactive coverage. For applications made on or after January 1, 2027, adults in the expansion group get a maximum of one month of retroactive eligibility before the month of application.

Retroactive coverage is what lets Medicaid pay medical bills from the weeks before someone applied. With a one-month limit, a bill from earlier than the month before the application month falls outside coverage for these adults. CMS’s deck does not set out retroactive rules for other eligibility groups, and the agency says it expects to issue additional guidance on section 71112.

What are states doing to get ready?

States that cover the adult group under their state plan must file a state plan amendment attesting to six-month renewals. CMS is building an online reviewable unit for those filings, targeted for the second half of 2026, and says states may submit by March 31, 2027 to comply by January 1, 2027. States with waiver coverage are told to contact their CMS project officer.

CMS also tells states to clear their application, renewal and fair hearing backlogs now, and plans further guidance on how the community engagement requirement will affect renewals. Medicaid’s main site, Medicaid.gov, is the federal starting point, and each state’s agency sends the actual notices. The open question for adults on expansion Medicaid is which of CMS’s two transition options their own state picks, because that decides whether the first six-month renewal lands in January 2027 or later in the year.

Ready for a Medicaid renewal every six months?

An adult on expansion Medicaid who misses one of the new six-month renewals can lose coverage, and the 30-day response window CMS describes leaves little room to hunt for pay stubs or letters. Starting January 2027, the paperwork comes around twice as often.

The SNAP & Medicaid Renewal Organizer has a renewal document checklist, a renewal and reporting calendar and 51 state packs, plus the 90-day window after coverage is dropped. The calendar is built for exactly the kind of repeating dates a six-month cycle creates.
