CMS Is Hunting Down 1.2 Million Overlapping Medicaid Enrollments — and Nursing Homes Are Asking What It Means for Their Bottom Line

Washington, District of Columbia — Federal health officials have identified roughly 1.2 million people each month whose Medicaid or CHIP coverage overlaps across state lines, and the agency in charge is now moving to clean it up. For nursing homes, the question is what that cleanup means for payments already stretched thin.

Medicaid Director Dan Brillman laid out the effort during a recent press briefing, saying the Centers for Medicare and Medicaid Services is working with states to resolve existing cases and build a national system for more consistent enrollment checks. Starting in January, states will be required to regularly verify beneficiaries’ addresses.

“We have a system of 50 different systems that are operating in silos that don’t speak to each other,” Brillman said.

Why providers are watching closely

The push arrives alongside a broader anti-fraud campaign and a wave of new Medicaid eligibility and work requirements, plus more frequent routine verifications. Those changes have already stirred concern across the long-term care sector — specifically, how quickly residents will get their Medicaid coverage approved and whether facilities will be left holding more bad debt in the meantime.

There’s more. The Department of Health and Human Services has also published a notice granting CMS new power to remove providers, insurers and suppliers from federal health programs over fraud concerns. Previously, that exclusion authority sat solely with the HHS inspector general. Officials say the change aligns enforcement responsibilities within CMS; it doesn’t strip the inspector general of existing authority.

The cross-state problem

CMS didn’t announce any nursing home-specific requirements during the briefing. But the stakes are easy to see. Medicaid is the largest payer of nursing facility care in the country, and federal rules generally require coverage for people who meet the eligibility criteria. Under the planned system, CMS wants to help states spot current enrollment overlaps, block new ones, and eventually let coverage transition more smoothly when beneficiaries move between states.

The movement numbers are bigger than many realize. Census Bureau data estimates about 3.15 million American adults 65 and older move each year, and nearly one in five of them crosses a state line.

What remains unclear is whether tougher eligibility checks or state-level enrollment corrections will slow payment timelines, add administrative workload, or complicate coverage transitions for residents admitted from out of state. CMS has not detailed how the national enrollment system would interact with nursing home admissions or billing systems, and providers aren’t the only ones asking — the same verification push follows a federal report showing nursing home fines fell sharply even as deficiencies rose, another sign that oversight machinery is being retooled across the board.

For an industry where a single delayed Medicaid approval can mean weeks of uncovered care, the answers can’t come soon enough.
