The Question · Mental health · Medicaid work requirements
Your patients' work rule exemption will be read from your claims.
From January 1, 2027, adults 19 to 64 in covered Medicaid groups must show 80 hours a month of work or other activity. People with a substance use disorder or a disabling mental disorder can be exempt as medically frail. States check that against 12 months of claims, including yours.

The question we asked on LinkedIn
Medicaid work requirements start January 1, 2027. Should your BH clinic help patients prove the medically frail exemption, or leave it to the state?
Monthly activity requirement
Work, education or community service, ages 19 to 64, from January 1, 2027
Claims look-back for frailty
Paid, pended and denied claims plus encounter data, per the June 2026 IFC
SUD recovery cut-off
People in stable recovery 5 or more years are not medically frail under the IFC
Court ruling on the test
A Massachusetts federal court struck the added impairment test
How a state decides a BH patient is exempt
Under 42 CFR 435.554 as issued in the interim final rule, data comes first and paperwork second.
Claims check
The state searches 12 months of adjudicated claims and encounter data for a qualifying condition.
Category match
SUD, disabling mental disorder, disability, blindness or a serious or complex condition.
Attestation if no data
Allowed through 2027. From January 1, 2028 only once per enrollment period.
Re-check
Frailty is re-verified at least every 12 months, even for conditions unlikely to change.
The five medically frail categories
From the regulation text at 42 CFR 435.554(c)(5) in CMS-2454-IFC, 91 FR 33348.
| Category | What the rule says | BH billing note |
|---|---|---|
| Substance use disorder | Qualifies, except stable recovery of 5 or more years | SUD diagnoses on claims in the last 12 months show it |
| Disabling mental disorder | Qualifies as a category | Specific diagnosis codes help more than unspecified ones |
| Blind or disabled | As defined in section 1614 of the Act | Usually already known to the state |
| Physical, intellectual or developmental disability | Must limit one or more activities of daily living | Document function, not only diagnosis |
| Serious or complex medical condition | A long list of acuity tests | Often co-occurs with SMI |
Where the rule stands
- Jun 3, 2026
CMS-2454-IFC published at 91 FR 33348.
- Jul 31, 2026
IFC effective and comments close.
- Oct 29, 2026
Massachusetts federal court strikes the added impairment test; upholds the 12-month look-back and attestation limit.
- Jan 1, 2027
Work requirements apply. Date unchanged by the ruling.
- Jan 1, 2028
Self-attestation of frailty limited to once per enrollment period.
What the court changed, and what it left
The ruling sets aside one test nationwide. The injunction and a 6-month enforcement stay cover the 25 plaintiff states and DC.
Struck down
- A second test that the condition seriously limits the ability to comply
- Extra functional proof on top of the five statutory categories
Still in force
- The 12-month limit on claims used as evidence
- One self-attestation per enrollment period from 2028
- The January 1, 2027 start date
- The 80-hour monthly requirement
Why this lands on BH revenue
Coverage loss is a denial
A patient who loses Medicaid mid-treatment turns next month's visits into eligibility denials or self-pay. See six-month redeterminations.
Denied claims still count
The rule counts paid, pended and denied claims. A claim denied for a billing error still shows the diagnosis to the state.
Inpatient stays can pause it
Inpatient psychiatric and IMD stays fall under the short-term hardship rules in the IFC.
Is your clinic ready for January 1?
Tick what is true today.
The medically frail exemption is decided mostly from claims. Code SUD and mental health diagnoses to full specificity, keep claims flowing for every active patient, and ask about exemption status at every intake.
Questions operators ask next
Are people with substance use disorder exempt from Medicaid work requirements?
In most cases, yes: The statute and CMS interim final rule list substance use disorder as a medically frail category, which exempts the person from the 80-hour monthly requirement. The rule excludes people in stable recovery, defined as 5 or more years. States verify the condition using claims and encounter data from the preceding 12 months.
What did the October 29, 2026 court ruling change?
A federal district court in Massachusetts set aside the IFC requirement that a medically frail person's condition must also seriously limit their ability to comply. The court upheld the 12-month claims look-back and the one-time self-attestation limit. It did not delay the January 1, 2027 start date. Watch for an appeal.
How do states verify medically frail status?
The IFC tells states to try reliable data first, including adjudicated claims from the preceding 12 months and encounter data. If no data exists, the person can self-attest through 2027. From January 1, 2028, attestation is allowed only once per enrollment period, and status is re-verified at least every 12 months.
Who must meet Medicaid work requirements in 2027?
Adults ages 19 to 64 in the expansion group and certain waiver groups must show 80 hours a month of work, education or community service, starting no later than January 1, 2027. Exemptions include medically frail individuals, pregnancy, caregivers and people meeting SNAP or TANF rules, among others.
