How to Check State Medicaid Exclusion Lists
By Keelstar Team · Updated June 1, 2026
The short answer
Identify which state Medicaid programs your organization bills or where your patients and vendors operate, then search each applicable state exclusion or sanction list using legal names and aliases. State exclusions do not always appear on the OIG LEIE immediately. Document every search with date and result, and include state checks in your employee and vendor re-screening schedule.
Why state lists exist separately from OIG
States administer Medicaid and can exclude providers for fraud, abuse, licensing violations, or patient harm — sometimes before or instead of federal action. Payer contracts and state survey requirements increasingly ask for proof of state list screening, not just OIG.
Which states to check
At minimum, screen the state where your organization is licensed and bills Medicaid. Also consider states where remote staff are licensed, where agency nurses are placed, and where billing vendors process claims. Telehealth expanded this footprint for many practices.
Employees vs vendors
Apply state screening to licensed clinicians, billing staff touching state claims, and vendors performing Medicaid-billable services. A physician excluded in one state may still hold privileges elsewhere until action propagates — state checks catch gaps OIG timing misses.
Operational challenges
There is no single federal portal for all state lists. Formats vary — some states offer searchable databases, others publish PDF bulletins. Manual programs often skip states beyond the home state; that is a common audit finding for regional health systems and staffing firms.
Reduce false positives
Like OIG, state lists are name-based. Compare NPI, license number, date of birth, or address when resolving potential matches. Document false-positive dispositions with the identifiers you compared.
Integrate with onboarding
Add state list checks to the same vendor packet gate as OIG — no PO, no system access, no schedule until complete. For employees, run state checks at hire and on the same re-screen cadence as federal lists.
Frequently asked questions
- Do I need every state if we only operate in one?
- Screen the state(s) where you bill Medicaid and where vendors perform services. Multi-state telehealth and locum programs often need multiple state lists.
- Where do I find state lists?
- Most states publish a Medicaid exclusion or provider sanction list on their health department or Medicaid agency site. Some participate in multistate data sharing, but do not assume one search covers all states.
