Medicaid work requirements start January 2027. Is your family member exempt?
Eighty hours a month, ages 19 to 64, starting January 1, 2027. Your adult child is almost certainly exempt. Arkansas proved that being exempt and being able to prove it are two different things.
The rule directs states to check existing claims and administrative data before asking you for anything. That means the fight is won or lost inside your adult child’s billing history, before you are ever contacted. Ask the treating physician to document the qualifying condition explicitly at the next visit, using the diagnostic language and codes that carry it: intellectual or developmental disability, disabling mental disorder, blindness or disability, or a serious or complex medical condition. A diagnosis coded this year is an automated exemption next year.
Who it hits
Non-pregnant adults ages 19 to 64 who are not enrolled in Medicare, in states that expanded Medicaid.
Who is exempt
Medically frail individuals, including people with physical, intellectual, or developmental disabilities, disabling mental disorders, blindness or disability, substance use disorder, and serious or complex medical conditions.
18,000
The Arkansas lesson
When Arkansas ran work requirements, roughly 18,000 people lost coverage in a matter of months. Many of them qualified for an exemption they could not document in time.
30
The 30-day window
When the automated check fails, you get 30 days to demonstrate compliance or prove an exemption. Thirty days, by mail, to a family that may not open the letter for two weeks.
Self-attestation ends
Self-attestation is permitted only temporarily, through January 2028, and only once per continuous enrollment when automatic verification fails. At renewal, provider certification or medical records become required.
Already started
Nebraska began May 1, 2026. Montana, Arkansas, and Iowa followed on various 2026 dates. States may start earlier than the federal date.
The exemption categories, verbatim

Pregnancy, tribal members, former foster youth, disabled veterans
In Arkansas the letters went to addresses people had moved away from, describing an online reporting portal that closed at nine at night, in a state where a lot of the affected population did not have reliable internet. Roughly 18,000 people lost coverage. The state did not decide they were ineligible. It decided they had not proven otherwise, in time, in the format required.
Build the exemption file in 2026, not 2027
Do these before January
- 1Confirm your adult child’s current Medicaid category.
- 2Ask the physician to document the qualifying condition.
- 3Confirm the diagnosis codes are in current claims data.
- 4Update the mailing address on file with the state.
- 5Add an authorized representative to the case.
- 6Calendar the renewal date and open every envelope.
What proves medically frail
- Physician letter naming the qualifying condition
- Current diagnosis codes in active claims history
- Functional impairment described, not just diagnosed
- SSI or SSDI award letter, if applicable
- Recent hospitalizations, ER visits, crisis contacts
- Behavior support plan or psychiatric records
- The IPOS or waiver plan showing support hours
- Two copies of everything, one in the binder
The state is required to check its own data first. Your job in 2026 is to make sure its data already says what you would otherwise have 30 days to prove.
The letter will not say your adult child is losing Medicaid. It will say something procedural about community engagement requirements and reporting, and it will include a deadline, and if you are the kind of tired that comes with caregiving you may put it on the counter with the other mail. That is what happened in Arkansas. Roughly 18,000 people lost coverage, and a lot of them were exempt the entire time.
What the rule requires
CMS issued an interim final rule, CMS-2454-IFC, on June 1, 2026, implementing the Medicaid community engagement requirement. The compliance date is January 1, 2027, and states may start earlier. Several already have. Nebraska began May 1, 2026, with Montana, Arkansas, and Iowa following on various 2026 dates.
The requirement itself is 80 hours per month of qualifying work, education, job training, volunteer service, or similar activity, for non-pregnant adults ages 19 to 64 who are not enrolled in Medicare. States must verify compliance at application, at renewal, and at state option more frequently than that.
If you are reading this because you have an autistic adult child, the requirement almost certainly does not apply to them. The exemption almost certainly does. The rest of this post is about the gap between those two sentences.
The exemptions, and the one that matters most
The rule lists several excepted groups. Former foster care youth. American Indians and Alaska Natives. Parents, guardians, and caretaker relatives caring for children 13 and under or for disabled individuals. Veterans with a total disability rating. People in drug or alcohol rehabilitation programs. Inmates of public institutions. Pregnant and postpartum individuals. People already meeting SNAP or TANF work requirements.
And the category that covers most of the people this site is written for: medically frail or otherwise having special medical needs that significantly impair the ability to comply.
The rule identifies five qualifying conditions under medical frailty, each requiring functional impairment. Blindness or disability. Substance use disorder. Disabling mental disorders. Physical, intellectual, or developmental disabilities. Serious or complex medical conditions, with cancer, HIV/AIDS, end-stage renal disease, heart disease, multiple sclerosis, and Parkinson’s named as examples.
Read the third and fourth of those again. Intellectual and developmental disabilities are named. Disabling mental disorders are named. If your adult child has a documented autism diagnosis with functional impairment, they are inside the exemption as written.
Note the phrase “requiring functional impairment.” The diagnosis alone is not the test. The diagnosis plus documented functional impairment is the test. That distinction is going to decide a lot of cases.
How the verification actually works, and why 2026 is the year that counts
This is the part that changes what you should do, so I want to be precise about it.
States must first use existing Medicaid claims or administrative data to verify whether someone is exempt. They are required to develop auditable ICD-10 code lists aligned with the federal definitions. In plain language: before anyone contacts you, a computer looks at your adult child’s billing history and asks whether the codes in it match the exemption list.
If that automated check clears, most families will never hear about any of this. If it does not clear, you get 30 days to demonstrate compliance or prove an exemption.
Self-attestation, meaning you simply say your adult child is exempt, is permitted only temporarily, through January 2028, and only once per continuous enrollment period when automatic verification fails. At renewal, documentation such as provider certification or medical records becomes required.
What Arkansas actually taught us
Arkansas implemented Medicaid work requirements and roughly 18,000 people lost coverage before a court stopped it.
The instructive part is not that the state was hostile. It is that the failure was administrative. Notices went to old addresses. Reporting had to happen through an online portal. People who were exempt did not know they had to report that they were exempt, or could not navigate the system that let them say so.
Coverage was not lost because people refused to work. It was lost because a paperwork process ran on a schedule that real human lives do not run on.
Every family reading this should assume the same failure mode. Not malice. Mail, deadlines, portals, and a thirty-day window that starts whether or not you opened the envelope.
That is a fixable risk, and the fix is boring. Update your address. Add an authorized representative so notices reach a second person. Open the mail. Calendar the renewal date. Make sure the diagnosis is coded correctly before anybody asks.
Your practical next steps
This month. Call your state Medicaid office or check the online account and confirm the mailing address, phone, and email on your adult child’s case. Add yourself as an authorized representative if you are not already listed. A notice that reaches nobody is the single most common way coverage is lost.
At the next medical appointment. Ask the physician to document the qualifying condition explicitly, with functional impairment described, not just the diagnosis code. Ask for a letter and keep two originals.
Before the end of 2026. Confirm the diagnosis appears in current, active claims data. A diagnosis in a 2014 evaluation that has not been billed since does not help an automated check that reads recent claims.
If a notice arrives. Read the date. You have 30 days. Respond in writing, attach the physician documentation, and keep a copy with the postmark or the confirmation. Do not rely on a phone call.
Your adult child is exempt. That is not the question. The question is whether the state’s computer knows it in December, or whether you find out in a January envelope with a thirty-day clock already running.
