Federal court strikes down CMS medical frailty "impairment clause"

Key Takeaways

On October 29, a U.S. District Court struck down the "impairment clause" for Medicaid medical frailty exemptions that was included in the Centers for Medicare and Medicaid Services (CMS) final rule implementing the Medicaid community engagement and work requirements under H.R. 1. The ruling prevents an administrative burden for county eligibility officers and provides more clarity on eligibility status for chronically ill beneficiaries. Though the ruling exclusively targets the definition of medical frailty, the overall Medicaid work requirements scheduled to take effect on January 1, 2027, remain intact. 

In addition to D.C., the states that brought the lawsuit were Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, Washington and Wisconsin.

What is the "impairment clause"?

Under H.R. 1, individuals with serious or chronic medical conditions are statutorily exempt from the 80-hour monthly work requirement under the "medically frail" exception. However, CMS added an additional hurdle in its implementing regulations: enrollees had to 1) prove that they had a qualifying diagnosis, and 2) submit paperwork showing that their condition "significantly impaired" their functional ability to work.

A coalition of Democratic-led states and D.C. sued, arguing this extra test exceeded the clear statutory language of H.R. 1. The judge agreed and directed CMS to strip the impairment clause.
In practice, the medical frailty exemption still exists, but it is now much easier to obtain. Enrollees no longer need to pass an evaluation proving how their illness limits their daily capacity to work, and showing clinical proof of a qualifying diagnosis or medical condition can now be sufficient. 

What did the court uphold?

Though the court struck down the impairment clause, the judge sided with the federal government on several other administrative provisions in the CMS rule:

•  The court upheld the requirement that states must reject proof of a patient's medical frailty, such as a hospital admission or diagnosis, that is more than 12 months old. States argued this will lead to procedural disenrollments because frail individuals often go longer than a year between major health events.

• Starting in 2028, Medicaid expansion enrollees nationwide can self-attest to their exemption once, but must provide formal medical documentation during their next renewal. Eight states have already rejected the single-year self-attestation period and will require full paperwork starting in 2027 to prevent fraudulent enrollments. The court rejected the states' argument that CMS should have mandated universal self-attestation.

  
  What is the county impact?

  
  The court’s ruling impacts county governments in a number of ways. When chronically ill beneficiaries lose Medicaid coverage due to complicated paperwork requirements, they do not stop needing medical care. Instead, they turn to county-operated hospitals, health departments and emergency rooms, often leaving county taxpayers to absorb the costs of uncompensated care. Striking down the additional hurdle of the impairment clause helps keep vulnerable individuals connected to coverage and stable care.

  
  This also prevents a major administrative burden for county eligibility workers. Requiring caseworkers to evaluate whether a medical condition "significantly impairs" someone's functional ability to work can be incredibly labor intensive for counties that process Medicaid applications. Reverting to standard medical diagnosis documentation keeps the verification process straightforward for frontline staff.

  
  While the overall January 1, 2027, rollout date for H.R. 1's work requirements remains unchanged, the court granted a six-month hold-harmless period exclusively to the 25 plaintiff states and D.C. This temporary buffer protects counties in these jurisdictions from federal compliance penalties or accidental coverage terminations while eligibility offices update IT infrastructure, train staff, and recalibrate verification workflows. However, because the grace period applies only to the litigants, non-suing states must adapt to the new medical frailty standards without this operational safety net.

  
  What’s next?

  
  The federal government is almost certain to appeal the ruling, which could re-introduce administrative uncertainty for states, counties and beneficiaries as the 2027 implementation deadline approaches. As states implement these changes, NACo will continue to monitor the impacts on counties.
