CMS Directs States to Audit and Revalidate Medicaid Providers
Summary
CMS Administrator Mehmet Oz announced on April 21, 2026 at Politico's Public Health Care Summit that all 50 states will be required to submit Medicaid provider revalidation plans within 30 days. States must immediately audit and verify providers paid by their Medicaid programs, focusing on high-risk areas to confirm provider legitimacy, using advanced technology and data analytics. CMS is instructing states to continue leveraging data analytics tools, with further details on the initiative to be announced.
“On April 21, Centers for Medicare & Medicaid Services (CMS) Administrator Mehmet Oz announced that all 50 states will be required to submit provider revalidation plans within 30 days.”
Medicaid-enrolled providers, particularly those in high-risk service categories such as home health, personal care, and durable medical equipment, should audit their enrollment records and billing documentation now in anticipation of intensified state-level revalidation reviews. The 30-day window for state plan submissions means that increased audit activity at the state level could follow rapidly.

What changed
CMS has announced a new enforcement initiative requiring all 50 state Medicaid agencies to submit provider revalidation plans within 30 days, announced by Administrator Mehmet Oz at Politico's Public Health Care Summit on April 21, 2026. The initiative builds on existing federal regulations requiring provider revalidation at least every five years but demands immediate demonstration of compliance, with states instructed to use advanced data analytics to identify fraud.
Healthcare providers enrolled in Medicaid should proactively review their enrollment records for accuracy and completeness and self-audit their billing and documentation practices. State Medicaid agencies face a 30-day deadline to submit their revalidation plans to CMS and should prepare for heightened scrutiny of high-risk provider categories.
What to do next
- State Medicaid agencies must submit revalidation plans within 30 days
- State Medicaid agencies must immediately audit and verify providers paid by their state's Medicaid program
- State Medicaid agencies must focus audits on high-risk areas using advanced technology and data analytics

CMS Directs States to Audit and Revalidate Medicaid Providers
The federal government is escalating its crackdown on Medicaid fraud and every state has been placed on notice.
On April 21, Centers for Medicare & Medicaid Services (CMS) Administrator Mehmet Oz announced that all 50 states will be required to submit provider revalidation plans within 30 days. Speaking during Politico’s Public Health Care Summit, Oz said that states will be called on to immediately audit and verify providers paid by their state’s Medicaid program. Oz said the revalidation audit must focus on “high risk” areas, with the goal of confirming that all Medicaid providers are “legitimate.”
Under existing federal regulations, state Medicaid agencies are required to revalidate providers at least every five years. With this initiative, CMS is requiring that states demonstrate compliance immediately. To aid this effort, CMS is instructing states to continue to use advanced technology and data analytics. “Data clues us in to where the fraud is,” Oz said. Further details on this initiative will be announced later this week.
With this announcement, it is clear that the government’s coordinated effort to root out Medicare and Medicaid fraud is not slowing. To get ahead, providers should ensure that their enrollment records are accurate and complete and should self-audit their billing and documentation practices.
