CMS Medicaid provider enrollment and revalidation

Steps

1. Enroll in each state Medicaid program separately through the state's provider enrollment portal — there is no federal single-enrollment system for Medicaid (unlike Medicare's PECOS).
2. Submit required enrollment data including NPI, taxonomy code, tax ID, practice location, ownership information, and state-required supporting documents (license, DEA, malpractice proof).
3. Monitor revalidation deadlines: 42 CFR Part 455 requires states to revalidate all provider enrollments at least every five years; some states revalidate higher-risk provider types more frequently.
4. Track revalidation notices from each state Medicaid agency; failure to respond to a revalidation request within the state's deadline results in automatic disenrollment and payment suspension.
5. Use each state's Medicaid Management Information System (MMIS) provider portal for enrollment status queries — some states expose enrollment status through a public provider lookup tool.
6. For multi-state practices, maintain a state-by-state enrollment matrix tracking enrollment date, revalidation due date, enrolled locations, and authorized services for each state.
