Judge denies the 26-state bid to pause the Medicaid work-requirement rule — CMS-2454-IFC takes effect July 31 with the 'sick enough' test intact, and the August 31 notification clock is fully live

On July 29, 2026 — one day after the July 28 hearing — Judge Richard G. Stearns (D. Mass.) DENIED the preliminary injunction in Commonwealth of Massachusetts v. Oz (1:26-cv-12962), the 25-state-plus-DC challenge to CMS's Medicaid work-requirement interim final rule.

Per reporting on the ruling, the denial rested on the states' failure to show irreparable harm — the court noted CMS has agreed to reimburse 90% of states' implementation costs — and it was issued WITHOUT PREJUDICE, with Judge Stearns signaling he intends to reach the merits of the narrowed 'medically frail' exemption before the January 1, 2027 implementation date.

The practical consequence is immediate: this was the last off-ramp before CMS-2454-IFC's July 31 effective date, so the rule takes full legal effect with the 'sick enough' test (42 CFR 435.554(c)(5)(i)) intact, the August 31 state member-notification deadline fully live, and the 80-hour/month requirement on track for ~5.6M community health center patients on January 1, 2027.

The AMA and Massachusetts Medical Society had been granted amicus status supporting the injunction on July 21. Implementation is already staggering state by state: per KFF's July 24 implementation analysis, 36 states plan a 1-month lookback for verifying the 80-hour/$580 requirement, while Idaho and Indiana plan 3-month lookbacks that forced them to begin enrollee notices in July 2026 — the earliest notice wave in the country.

For FQHC eligibility and clinical teams the message is: stop waiting for the courts. Documentation workflows for the frailty exemption need to exist before the notices land in patients' mailboxes.
