Federal Agency Publishes Implementation Guidance for Medicaid Work Rules

The Centers for Medicare & Medicaid Services this week released an interim rule spelling out how states must document employment status for adults enrolled in Medicaid, establishing a hard deadline of January 1, 2027, for full compliance. The guidance covers roughly 20 million adults who gained Medicaid eligibility through expansion under the Affordable Care Act.

To satisfy the new mandate, expansion enrollees must show at least 80 hours each month of work, formal schooling, vocational training, or community service. The rule carves out exceptions for people classified as medically frail and for current students.

Idaho Enacted Its Own Work Verification Law Earlier This Year

Idaho moved ahead of the federal timeline when Governor Brad Little signed House Bill 913 into law this year. That statute requires Medicaid applicants to show a three-month employment history before coverage begins and compels current enrollees to verify their employment status on a twice-yearly basis.

About 80,000 Idaho residents receive benefits through the state’s Medicaid expansion. Projections from state analysts indicate the verification process could strip coverage from as many as 34,000 of those individuals — roughly 44 percent of Idaho’s expansion population — depending on enforcement and the scope of exemptions applied.

State administrators will now need to evaluate whether Idaho’s existing framework satisfies the CMS interim rule or whether additional adjustments are required before the federal deadline arrives.

Administration and Critics Offer Sharply Different Assessments

CMS Director Dr. Mehmet Oz defended the policy as a pathway to self-sufficiency. “This rule helps Americans build skills and independence through work, education, job training, or community service, creating new opportunities for themselves and their families,” he said in an accompanying statement.

A bloc of six Democratic governors formally asked the Trump administration last week to slow the rollout. Oregon Governor Tina Kotek articulated the coalition’s core concern: “States are being asked to carry out a complicated federal mandate without clear rules, without enough time, and with the risk that eligible people lose health care because of paperwork problems and system failures.”

Arkansas Experience Clouds the Policy Debate

Arkansas was the first state to put Medicaid work requirements into practice, doing so in 2018. Before a federal judge stepped in to stop the program less than a year later, around 18,000 adults in the state had already lost their coverage. Research conducted after the program’s suspension found no evidence that the requirements produced measurable employment gains among those subject to them.

The new federal rule reaches across the 40 states — along with the District of Columbia — that expanded Medicaid eligibility; two additional states carried out partial expansions. According to the Kaiser Family Foundation, expansion enrollees make up approximately 30 percent of the entire Medicaid population. The Urban Institute has estimated that between 3 million and 7 million people nationally could lose coverage once work requirements are in force, a range that reflects uncertainty about how individual states will administer exemptions and handle verification failures.

What Comes Next for Idaho and Other States

With the interim rule now in effect, state health agencies face an 18-month window to build or update eligibility systems capable of processing work verification on the scale required. Idaho’s Department of Health and Welfare will need to determine how closely House Bill 913 aligns with the federal framework and whether any gaps require legislative or administrative remedies before the 2027 effective date.

Even states broadly supportive of work requirements have flagged the compressed implementation window as an administrative challenge. How Idaho resolves any differences between its own statute and the CMS standard could determine how many of the roughly 80,000 affected residents remain covered when the requirements take hold.
