CMS has until June 1, 2026 to issue an interim final rule defining who qualifies as "medically frail" under Medicaid work requirement exemptions. That's 18 days from today. Once the definition drops, it becomes the federal floor for every state implementing work requirements, and states can only expand it, not narrow it.

Right now, patient advocacy groups for sickle cell disease, HIV, and other chronic conditions are actively lobbying CMS to get their conditions explicitly included in the guidance before the June 1 deadline. If you have a family member with a chronic condition that isn't covered by the statutory exemption list, the window to act is now. After June 1, the definition is set.

What the Statutory Exemption List Says

The law exempts people who are:

• Blind
• Disabled (as defined under SSI or state disability determination standards)
• Have a physical disability
• Have an intellectual or developmental disability
• Have a substance use disorder
• Have a disabling mental disorder
• Have a serious and complex medical condition

The problem is that "medically frail" itself isn't fully defined in statute. CMS has discretion to interpret what counts as a "serious and complex medical condition" and what meets the threshold for "disabling mental disorder." That interpretation matters because it determines whether conditions like fibromyalgia, chronic pain, long COVID, or serious mental illness qualify for automatic exemption or require state-by-state determination.

Where the Gaps Are

If your family member receives SSI or SSDI, they're covered under the "disabled" category.

If they don't receive disability benefits but have a diagnosed condition, you're in the gray zone. CMS's early guidance suggested "medically frail" would include people with chronic conditions requiring ongoing treatment, multiple medications, or frequent hospitalizations. That's broad. The June 1 rule could narrow it.

Conditions that advocacy groups are pushing to keep explicitly protected:

• Sickle cell disease
• HIV
• End-stage renal disease
• Cystic fibrosis
• Cancer (active treatment or survivorship with complications)
• Hemophilia
• Multiple sclerosis
• Cerebral palsy (adults aging out of pediatric Medicaid)
• Severe asthma requiring daily medication and emergency care
• Type 1 diabetes with complications

If your family member's condition isn't on this list and doesn't meet the statutory categories, the June 1 guidance will determine whether they're protected or whether you'll need to request an exemption manually after the rule drops.

Why the Federal Definition Matters

States can be more expansive than the federal floor, but they can't be more restrictive. If CMS defines "medically frail" narrowly on June 1, states that wanted to offer broader protections can still do so, but states that wanted to be strict can't go below the federal standard.

That means the June 1 rule sets the minimum nationwide. If CMS excludes a condition from the medically frail definition, families in states that implement the bare minimum will lose automatic protection.

What to Do Now

1. Get Physician Documentation

Call your family member's primary care physician or specialist and request written documentation of their disabling condition. You want:

• A letter stating the diagnosis
• How the condition limits major life activities (working, walking, self-care, communication)
• Current treatment plan (medications, therapies, frequency of appointments)
• Prognosis or expected duration of the condition

Ask the physician to explicitly state whether the condition is "serious and complex" and whether it meets the standard for "disabling." Those terms appear in the statutory exemption list, and having them in the physician's letter now saves time later.

2. Check Your State's Medicaid Work Requirement Status

Not all states have implemented work requirements yet, but 41 states are rolling them out. If your state is on the list, assume you'll need to request an exemption once the June 1 guidance is issued.

Check your state Medicaid agency's website or call the eligibility office and ask:

• When work requirements take effect in your state
• What documentation is required to request a disability or medically frail exemption
• Whether the state has issued its own definition of medically frail (some states moved ahead of federal guidance)

3. File the Exemption Request as Soon as the Rule Drops

The moment CMS issues the June 1 interim final rule, read it. If your family member's condition is explicitly covered, file the exemption request immediately using the physician documentation you already have.

If the condition isn't explicitly covered but you believe it meets the "serious and complex medical condition" standard, file anyway. Include the physician letter, treatment records, and a written statement explaining how the condition limits your family member's ability to meet work requirements.

States must process exemption requests within 30 days under CMS rules. Filing early protects your coverage while the request is pending.

Appeal Rights If Denied

If your state denies the exemption, you have the right to appeal. The appeal process varies by state, but you typically have 60 days from the denial notice to file.

Your appeal should include:

• A copy of the denial notice
• Updated physician documentation
• Records of hospitalizations, emergency room visits, or frequent medical appointments in the past 12 months
• A written statement from the family member or caregiver explaining how the condition prevents compliance with work requirements

States must hold a hearing and issue a decision within 90 days of the appeal filing. During that time, your Medicaid coverage continues if you file the appeal within 10 days of the denial.

Resources

The American Medical Association (AMA) published guidance for physicians on documenting disability and medically frail status for Medicaid work requirement exemptions. Share it with your doctor if they're unfamiliar with the process: AMA Medicaid Work Requirement Guidance.

The Center on Budget and Policy Priorities (CBPP) tracks which states have defined medically frail and how they're interpreting the federal exemption categories: CBPP Medicaid Work Requirements Tracker.

If your family member has a rare disease or a condition with an active patient advocacy organization, contact that organization now. Many are coordinating comment submissions to CMS before June 1 and can connect you with sample exemption request language.

What Happens After June 1

Once the interim final rule is published, CMS typically opens a public comment period (30–60 days). Comments won't change the interim rule, but they influence the final rule, which could be issued months later. If the June 1 guidance excludes your family member's condition, submit a comment explaining why it should be included in the final rule.

The interim rule is enforceable immediately. That means states will use it to process exemption requests starting June 1, even if the final rule isn't published until later in 2026.

Final Note

The statutory exemption list is clear on disability status, blindness, intellectual and developmental disabilities, and substance use disorders. If your family member fits one of those categories, you're covered. The ambiguity is in "medically frail" and "disabling mental disorder." Those are the terms CMS will define on June 1, and those are the categories where families need documentation ready now.

You can't control what CMS publishes, but you can control whether you have the paperwork in hand when the guidance drops. Get the physician letter now. Don't wait until June 2.
