A federal judge rejected the federal government’s new definition of “medical frailty” and ruled that states did not have adequate time or resources to overhaul eligibility systems.

The details: The judge ruled that the federal regulations were too restrictive and said that the lawsuit successfully demonstrated that implementation of the work requirements, as written, would cause “irreparable harm.”

The main point: The ruling blocks the CMS interim final rule published in June that narrowed the definition of “medically frail.” But the broader Medicaid work requirements remain in place, with enforcement beginning Jan. 1.

Meanwhile: CMS also issued new guidance for states highlighting potential solutions to a list of nearly two dozen anticipated problems in implementing Medicaid work requirements, as many states acknowledge that their systems are not yet capable of handling the new requirements. But some of the mitigation steps outlined would add to workload or costs, including by asking states to create temporary work-arounds or expand call centers’ capacity. It remains unclear whether states can deploy these stopgaps by the start of the year, and questions about oversight remain.
