HHS inspector general flags $200M errors
- HHS-OIG audits in 2024 through 2026 found Indiana, Wisconsin, Maine, and Colorado made at least $197.9 million in improper Medicaid autism-service payments. - The biggest single finding was Colorado — at least $77.8 million improper, with every one of 100 sampled enrollee-months showing improper or potentially improper claims. - The wider fight is over oversight, not one scam — and Ohio’s separate Medicaid audits are adding more pressure.
Medicaid oversight is having a rough month. The cleanest version of the story is this: federal auditors did not uncover one giant national autism-services bust, but they did stack up a series of state audits that point in the same direction — weak controls, bad documentation, and lots of money paid out anyway. Add those audits together and four states alone account for at least $197.9 million in improper Medicaid payments tied to autism services. ### What actually got flagged? HHS’s inspector general audited fee-for-service Medicaid payments for autism-related services in Indiana, Wisconsin, Maine, and Colorado. The services were mostly applied behavior analysis, or ABA, plus Maine’s broader rehabilitative and community support services. In every state, auditors said payments did not fully comply with federal and state rules. In every state, all 100 sampled enrollee-months contained at least one improper or potentially improper claim line. (oig.hhs.gov) ### How big is the total? The state-by-state numbers are pretty stark. Indiana came in at at least $56 million. Wisconsin came in at at least $18.5 million. Maine came in at at least $45.6 million. Colorado came in highest at at least $77.8 million. Add them up and you get $197.9 million — basically the “about $200 million” figure now circulating. (oig.hhs.gov) ### Why do these audits keep finding the same thing? Because the problem looks less like one fake-provider ring and more like a payment system that approves claims without enough proof behind them. The audit recommendations repeat almost verbatim across states: refund the federal share, tighten provider guidance, and run post-payment reviews. That tells you the weak point is administrative control — documentation standards, billing rules, credentialing checks, and after-the-fact review. (oig.hhs.gov) ### Why is Colorado getting so much attention? Colorado is the largest single finding so far, and the growth in spending was fast. Its fee-for-service Medicaid payments for ABA rose from $60.1 million in 2019 to $163.5 million in 2023. Auditors then estimated at least $77.8 million in improper payments and recommended that Colorado refund $42.6 million as the federal share. When spending rises that quickly, even ordinary control failures get expensive fast. (oig.hhs.gov) ### Was Maine the new trigger? Pretty much. Maine’s report landed in January 2026 with a press release, so it gave the issue a fresh hook. That audit said Maine made at least $45.6 million in improper payments for 2023 autism-related rehabilitative and community support services, and recommended a $28.8 million federal refund. But Maine was not the start of the story — it followed Indiana in December 2024 and Wisconsin in July 2025, then Colorado in February 2026. (oig.hhs.gov) ### Where does Ohio fit in? Ohio is a separate lane, but politically it blends into the same “Medicaid integrity” argument. One Ohio audit said the state made more than $1 billion in managed-care payments over four years for people concurrently enrolled in multiple states, with a potential financial impact above $200 million. Another Ohio audit on electronic visit verification said the state spent about $2 billion on personal care and home health services in 2022 while EVV was used for only 44% of paid claims. (oig.hhs.gov) Ohio Medicaid disputes parts of that picture, especially the methodology and the headline numbers. ### Does “improper” mean fraud? Not necessarily — and that distinction matters. “Improper” can mean unsupported, undocumented, miscoded, or otherwise noncompliant, not automatically criminal. But the practical effect is the same for policymakers: once auditors keep finding the same control failures, states get pushed toward tighter prior authorization, tougher documentation, more post-payment review, and more aggressive provider screening.

The bottom line is simple — the federal government is signaling that home- and community-based Medicaid spending, especially fast-growing services for vulnerable patients, is headed for much closer scrutiny.
