CMS Rule Requires Doctors to Prove Illness 'Significantly Impairs' Ability to Work Before Medicaid Exemption

A tighter bar for medical exemptions

Since Congress passed H.R. 1 in the summer of 2025, imposing new work reporting requirements on many Medicaid enrollees as part of more than $1 trillion in healthcare cuts, the fight has moved from the law itself to how it gets carried out. In June 2026, the Centers for Medicare & Medicaid Services released an interim final rule spelling out how states must verify who is exempt from those requirements for medical reasons, according to a physician's op-ed published in MedPage Today.

Under the new rule, a diagnosis alone is not enough. State Medicaid programs must confirm that a patient's condition "significantly impairs" their ability to meet work requirements, the pulmonologist writes. That is a subjective standard with no clear process attached to it yet.

'Will physicians be expected to make these determinations?'

The op-ed's author, a practicing pulmonologist, says the rule leaves basic operational questions unanswered. Chief among them: who decides whether a condition "significantly impairs" a patient, the treating physician or a state caseworker? "Many providers, like me, may feel these determinations are outside of our areas of expertise," the doctor writes, adding that it would pile a new administrative burden onto physicians already drowning in prior authorization paperwork and insurance denials.

The patients most exposed, according to the op-ed, are people managing lung cancer, COPD, and pulmonary fibrosis. These conditions already require frequent hospital visits and ongoing treatment. Requiring them to repeatedly document and re-document that their illness meets a vague federal threshold adds friction to care that is already complicated.

The author points to a specific case: a woman named Carla, who lost her job weeks before being diagnosed with lung cancer and told members of Congress in April 2025 that Medicaid coverage let her get the biomarker testing and treatment that saved her life. The op-ed argues lawmakers promised patients like her would be shielded from losing coverage over paperwork technicalities, and that the June 2026 rule undercuts that promise.

The case for work requirements, stated fairly

Supporters of Medicaid work requirements argue the policy is basic accountability: a program funded by taxpayers should prioritize people who are working, looking for work, or genuinely unable to, not able-bodied adults who simply opt out. That is a mainstream conservative position and a reasonable one. Verifying medical exemptions, rather than accepting blanket claims, is consistent with that goal, and CMS has an obligation to make sure exemptions aren't rubber-stamped.

The problem the op-ed raises isn't the existence of a verification standard. It's that CMS built the standard without specifying who applies it or how, leaving doctors and state agencies to sort it out while sick patients wait.

The bureaucracy isn't unique to Medicaid

This fits a much bigger pattern documented outside the health policy world. Research cited by author writing for Lit Hub, drawing on estimates from Washington and the work of public administration scholars Pamela Herd and Donald Moynihan, puts the total time Americans spend filling out government paperwork, taxes, Medicaid applications, driver's license renewals, and loan forms at 12 billion hours a year. At prevailing wages, that unpaid labor is worth roughly $430 billion annually. Herd and Moynihan's framework breaks that burden into three types of cost: learning what programs exist, applying for them, and complying with ongoing rules. This is exactly the kind of compliance friction the new Medicaid exemption standard adds.

Political scientist Elizabeth Cohen, also cited in that piece, argues that burning people's time through red tape is itself a barrier to equal treatment under government programs, since lower-income Americans interact with these systems far more often than anyone else.

What's unresolved

CMS has not published detailed guidance on who makes the "significant impairment" determination or what documentation will satisfy it. The rule is an interim final rule, meaning it took effect without the standard notice-and-comment process, though a comment period can still shape a final version. Whether Congress, which the MedPage Today op-ed calls on directly, will step in to force clearer exemption standards before state Medicaid agencies start enforcing the rule remains an open question.
