States challenge CMS's medically frail exemption test; the agency defends its authority
States challenged CMS's requirement that medical frailty significantly impair a person's ability to meet Medicaid work requirements. CMS defended the test. An October 29 ruling struck that added condition while upholding two other challenged provisions.

Case period:
Published by The Dispute Index editorial teamPublished Updated
Overview
Congress listed categories of people included in the medically frail exemption. CMS added a requirement tying an individual's condition to their ability to comply with the community-engagement requirement. The states argued that this narrowed the statutory exemption; the government argued that the listed categories did not require every person within them to qualify.
The October 29 opinion vacates the added impairment condition and permanently enjoins its enforcement. It upholds a twelve-month claims-data lookback and a limit on self-attestation. A six-month enforcement stay applies to the plaintiff states' determinations of medical frailty while they change their verification systems to implement the ruling. It does not postpone the January 1, 2027 start of work requirements as a whole.
