The CMS Interim Final Rule published June 3, 2026 (CMS-2454-IFC) revealed something most coverage of Medicaid work requirements missed: six states opted out of accepting self-attestation for the "medically frail" disability work exemption.

If you're enrolled in Medicaid expansion in Arkansas, Hawaii, Indiana, Montana, North Carolina, or Utah, and you have a disability but don't receive SSI, SSDI, or Medicare, you can't simply tell your state Medicaid agency you're disabled and exempt from work requirements. You need formal medical documentation before January 2027 work requirements go live.

The general guidance released by CMS said all states must accept self-attestation through December 31, 2027, giving families time to gather formal documentation. That's true in 44 states but not in these six. Here's what you need to do if you're in one of them.

Who This Affects

This documentation requirement applies to Medicaid expansion enrollees who:

• Have a disability or chronic condition that substantially limits daily functioning
• Do not receive SSI (Supplemental Security Income)
• Do not receive SSDI (Social Security Disability Insurance)
• Are not enrolled in Medicare

If you receive SSI, SSDI, or Medicare, you're automatically exempt from Medicaid work requirements nationwide. You don't need additional documentation. When your state sends an outreach notice, confirm your exemption status through the provided channel, but you won't need medical records.

If you're a parent or caretaker of a child under 6, you're automatically exempt from work requirements under a separate provision. You don't need to prove medically frail status unless you're claiming exemption based on your own disability.

This six-state opt-out affects people with disabilities who aren't enrolled in federal disability programs but qualify under CMS's broader "medically frail" definition: disabling mental disorders, substance use disorders, intellectual or developmental disabilities, physical disabilities, or serious chronic medical conditions.

What the Six States Require Instead

The IFR gives states two options for verifying medically frail status: self-attestation or third-party verification. Forty-four states are accepting self-attestation for at least the first year, but Arkansas, Hawaii, Indiana, Montana, North Carolina, and Utah require formal medical documentation from a licensed provider:

• A letter from your treating physician, psychiatrist, or specialist on letterhead confirming your diagnosis
• A statement that your condition substantially limits one or more major life activities or requires ongoing treatment
• Recent medical records from the last 12 months showing treatment history

Self-attestation in these states won't work. Checking a box that says "I have a disability" on a state Medicaid form will not exempt you from work requirements. You need documentation from a provider.

What Conditions Qualify as Medically Frail

CMS's June 1 interim final rule established five categories for medically frail status. These apply nationwide, including in the six opt-out states:

1. Blind or disabled individuals: Anyone receiving SSI or SSDI automatically qualifies.
2. Disabling mental disorder: Serious mental illness that substantially impairs daily functioning, including major depressive disorder, bipolar disorder, schizophrenia, and PTSD when documented by a mental health provider.
3. Substance use disorder: Active diagnosis or participation in treatment within the past 12 months.
4. Intellectual, developmental, or physical disability: Includes cerebral palsy, spina bifida, muscular dystrophy, Down syndrome, autism spectrum disorder, and physical impairments requiring assistive devices or substantial accommodation.
5. Serious or complex medical condition: Chronic conditions requiring ongoing treatment and substantially limiting one or more major life activities, including diabetes with complications, congestive heart failure, COPD, epilepsy, chronic kidney disease, and cancer.

The rule also includes a sixth open-ended category: "any other condition that CMS determines meets the statutory definition." CMS is currently evaluating whether specific high-acuity conditions like ventilator dependence, tracheostomy care, and dialysis confer permanent exemption without annual redetermination.

What Likely Won't Qualify

The IFR includes guidance on conditions that don't automatically meet the medically frail definition. This matters in the six opt-out states, because families with these conditions can't rely on self-attestation and need to prove substantial functional limitation through formal documentation.

CMS specifically notes that the following conditions don't automatically qualify unless they substantially limit major life activities or require complex ongoing treatment:

• Uncomplicated asthma
• Controlled hypertension
• Obesity without complicating conditions
• Type 2 diabetes without complications

If you have one of these conditions and you're in one of the six opt-out states, you'll need documentation from your provider that specifically describes how the condition limits your daily functioning or requires ongoing specialist care. A diagnosis alone isn't sufficient. The documentation needs to show functional limitation.

For example, if you have asthma that requires daily controller medication, limits physical activity, and necessitates quarterly pulmonologist visits, that may qualify. Your provider's letter needs to state that, not just list the diagnosis.

What to Ask Your Provider

When you request documentation, be specific. Tell your provider you need a letter for Medicaid medically frail exemption that includes:

• Your diagnosis
• A statement that your condition substantially limits one or more major life activities (walking, standing, lifting, concentrating, working, caring for yourself)
• Confirmation that your condition requires ongoing treatment or specialist care
• Recent treatment history (appointments, medications, procedures within the last 12 months)

Ask your provider to reference the CMS interim final rule (CMS-2454-IFC) and the five medically frail categories published June 1, 2026. Most providers won't be familiar with this yet. Bringing the rule reference helps them understand what CMS requires.

The letter doesn't need to be long. One page confirming diagnosis, functional limitation, and ongoing treatment is sufficient.

When to Submit Documentation

Most states will conduct outreach to Medicaid expansion enrollees between June 30 and August 31, 2026. That's when you'll submit documentation.

Montana starts work requirements July 1, 2026. Arkansas soft-launches July 1 with no disenrollment penalties until January 2027. The national work requirement deadline is January 1, 2027.

If you're in one of the six opt-out states and you haven't gathered documentation by the time your state's outreach window opens, you're subject to work requirements by default. That means 80 hours per month of work, job training, community service, or education. If you don't meet the requirement for three consecutive months, you lose Medicaid coverage.

Don't wait for the outreach notice. Get documentation from your provider now. If your state sends a notice in July and you don't have documentation ready, you'll be scrambling to get an appointment, wait for records, and submit everything before a deadline that may be 30 days out.

What to Do If Your State Denies a Medically Frail Exemption

If you submit documentation and your state denies your medically frail exemption, you have the right to appeal. Medicaid appeals processes vary by state, but most allow 30 to 60 days to request a hearing.

When you appeal, submit additional documentation that addresses the specific reason for denial. If the state said your condition doesn't meet the functional limitation threshold, get a more detailed letter from your provider that describes exactly how your condition limits daily activities. If the state said your treatment history doesn't show ongoing care, submit appointment logs, prescription records, or specialist referral notes.

You're entitled to continue Medicaid coverage during the appeal process if you request the hearing within the appeal window. That's called "aid continuing" or "continuation of benefits." Make sure you request it explicitly when you file the appeal.

What to Do If You're Already Subject to Work Requirements

If you're in Montana (work requirements started July 1), and you received a work requirement notice but didn't document a disability, you can still claim medically frail exemption retroactively. Submit documentation to your state Medicaid agency with a cover letter referencing the CMS interim final rule published June 3, 2026. If you were incorrectly flagged for work requirements, your exemption should be processed and your status corrected.

If you've already been disenrolled for failure to meet work requirements, submit a new application with medically frail documentation. Most states allow a one-time reinstatement window if you can prove you were exempt all along.

Why These Six States Opted Out

The IFR gave states discretion to choose between self-attestation and third-party verification for the first 18 months of implementation. After December 31, 2027, all states must accept third-party verification, but self-attestation is optional.

Arkansas, Hawaii, Indiana, Montana, North Carolina, and Utah cited concerns about fraud and program integrity as reasons for requiring documentation upfront. CMS approved these state plans in May 2026, but the details weren't publicly available until the June 3 IFR publication.

This matters because most advocacy groups, legal aid organizations, and news coverage of Medicaid work requirements have emphasized that self-attestation is available nationwide through 2027. That's accurate for 44 states. It's not accurate for these six.

The Timeline

• June 3, 2026: CMS publishes IFR revealing six-state opt-out (today)
• June 30 to August 31, 2026: Most states conduct outreach to Medicaid expansion enrollees
• July 1, 2026: Montana work requirements begin; Arkansas soft-launch with no disenrollment
• January 1, 2027: National Medicaid work requirement deadline; Arkansas begins enforcing penalties
• December 31, 2027: Self-attestation period ends nationwide; all states require third-party verification after this date

If you're in one of the six opt-out states, the practical deadline for gathering documentation is before your state's outreach window opens. For Montana enrollees, that was yesterday. For the other five states, it's late June or early July.

What to Do This Week

If you're enrolled in Medicaid expansion in Arkansas, Hawaii, Indiana, Montana, North Carolina, or Utah, and you have a disability or chronic condition that substantially limits your daily functioning, call your provider this week.

Request a letter for Medicaid medically frail exemption. Tell them you need it to include your diagnosis, a statement about functional limitation, and confirmation of ongoing treatment. Ask them to reference CMS-2454-IFC published June 1, 2026.

If you can't get an appointment within two weeks, ask if your provider can write the letter based on your existing medical records. Many providers will do this for established patients with documented conditions.

If your provider refuses or doesn't understand what you need, contact your state Medicaid agency and ask for the specific documentation requirements for medically frail exemption. Every state is required to publish this information as part of its work requirement implementation plan. Get it in writing, then bring it to your provider.

The self-attestation rule most families have heard about doesn't apply in these six states. If you wait until your state's outreach notice arrives and assume you can check a box, you'll lose time you can't get back. Get formal documentation now.
