A federal judge declined on July 29 to pause the rule that determines which Medicaid enrollees can be excused from work requirements on medical grounds. For people managing serious chronic illness, the documentation process is now going forward, and the first state mailings are due within four weeks.
States must notify enrollees about the changes by August 31, 2026. Requirements take effect January 1, 2027, in most states, with several already running them.
The exclusion is not automatic. Under the interim final rule, a serious diagnosis is not by itself enough. A person generally must show that the condition significantly impairs the ability to complete the required activity hours.
The Ruling Left the Rule Standing but Not Settled
Twenty-five states and the District of Columbia sued the Centers for Medicare and Medicaid Services on June 29 over the interim final rule published June 3, in a case jointly led by the attorneys general of California, Massachusetts and New Jersey. Some accounts count the coalition as 26 states.
The suit challenges three provisions in particular: the rule's inclusion of a work-related limitation in the definition of medically frail, its use of a 12-month look-back period when evaluating medical frailty, and its imposition of a work requirement on a short-term hardship exemption tied to emergency declarations.
U.S. District Judge Richard Stearns denied the states' motion for a preliminary injunction in Commonwealth of Massachusetts et al. v. Oz et al., finding they had not shown they were likely to suffer irreparable harm. He noted that CMS has agreed to reimburse 90 percent of state implementation costs, said he was not convinced states could not cover the remaining 10 percent, and pointed out that the deadline was set by Congress rather than by the agency.
The denial was issued without prejudice, meaning the states may renew the request. Stearns wrote that the questions raised are ones that should be made on a developed record of the kind that informs a decision at summary judgment, and STAT reported that the litigation will proceed toward a fuller hearing on the merits.
For an enrollee, the operative fact is simpler. No stay is in place, so preparation should not wait on the courts.
Which Conditions the Rule Actually Covers
The 2025 reconciliation law exempts people who are medically frail, a category that statutorily includes serious physical or intellectual disabilities, complex medical conditions, behavioral health conditions, and substance use disorder.
The interim final rule narrows how that is applied by tying medical frailty to a person's capacity to meet the requirement rather than to diagnosis alone. That is the change at the center of the lawsuit. In their complaint, the states argued that after months of regular communication with CMS and preliminary guidance on which they had based implementation plans, the agency adopted a rule that dramatically narrowed the categorical exclusions Congress established for some of the most vulnerable members.
Other categories are excluded regardless of health status: people under 19, people enrolled in Medicare, pregnant and postpartum individuals, former foster youth under 26, and veterans with a total disability rating.
Records Worth Gathering Before the Notices Arrive
States are expected to check available data first, including diagnosis and procedure codes, disability determinations, and prescription records.
Where data are incomplete, the burden shifts to the enrollee. The rule permits self-declaration when reliable data are unavailable, but only through 2027, and restricts auditable self-declarations for the medically frail exclusion in most circumstances.
That makes clinician documentation central. Useful records to assemble now include a letter from a treating clinician describing the condition and its functional effects on sustained activity, recent visit notes, hospitalization or emergency department records, current medication lists, dialysis or infusion schedules, therapy records for behavioral health or substance use treatment, and any existing disability determination.
Attestation authority varies by state and may extend beyond physicians to nurse practitioners, physician assistants, licensed clinical social workers, and behavioral health providers. Enrollees should confirm with their state Medicaid agency which clinicians it accepts before requesting a letter.
Verification is not one-time. States must reverify medical frailty at least every 12 months, even for conditions unlikely to change, and may do so more often.
The People Most Likely to Fall Through
Risk does not fall evenly. The enrollees most exposed are those whose conditions are serious but episodic, including people with multiple sclerosis, lupus, inflammatory bowel disease, severe mental illness and chronic pain conditions, where a good week on paper can undercut a claim built on a bad month.
Others at elevated risk include people whose address is out of date with the state agency, people without a consistent clinician able to attest, people in rural counties with limited eligibility assistance, and people whose primary language is not English. Adults in active recovery from substance use disorder should confirm their state's current treatment of that category rather than assume prior practice carries over.
Coverage loss under work requirements historically stems more often from paperwork failures than from failure to work. That is why the address on file with the state agency matters as much as the medical letter.
Dates That Matter Between Now and January
August 31, 2026 is the deadline for states to notify enrollees, and the requirements then take effect on January 1 in most states. Nebraska, Montana, and Arkansas have already begun implementation. Separately, eligibility redeterminations shift from annual to every six months beginning at the end of 2026.
The litigation continues, and the states may renew their injunction request if implementation produces concrete evidence of harm. A change in the medical frailty standard remains possible, which is a reason to keep documentation rather than discard it.
Anyone who receives a notice and believes it is wrong should ask the state agency about appealing and request a fair hearing within the stated deadline. Legal aid and health law advocacy groups assist at no cost. Do not stop prescribed medication or cancel appointments in anticipation of a coverage change that has not happened.
Frequently Asked Questions
Did the court stop the rule? No. The judge denied a preliminary injunction on July 29 without prejudice. The rule remains in effect, and the lawsuit continues.
Does a serious diagnosis automatically exempt me? Not under the interim final rule. The standard generally requires showing that the condition significantly impairs your ability to complete the required hours.
When will I hear from my state? States must notify enrollees by August 31, 2026. Confirm your mailing address with your state Medicaid agency now.
What documents should I gather? A clinician letter describing functional limits, recent visit and hospital records, medication lists, treatment schedules, and any disability determination.
Who can sign the attestation? That varies by state and may include nurse practitioners, physician assistants, and behavioral health providers. Ask your state agency before requesting a letter.
How often will I have to prove it again? At least every 12 months, and more often if your state chooses.
What if I am denied? Ask the state agency about appealing and request a fair hearing within the stated deadline. Legal aid and health law advocacy groups can help at no cost.
