How to Screen Pharmacy Vendors for OIG
By Keelstar Team · Updated July 11, 2026
The short answer
Pharmacy vendors — including retail pharmacies, specialty pharmacies, compounding pharmacies, and pharmacy benefit managers — require OIG LEIE screening before contracting and on a recurring schedule when they dispense or manage medications billable to Medicare or Medicaid. Screen legal entity names, DBAs, and individual pharmacists or owners when your policy requires principal screening. Pharmacy is a high-enforcement OIG category; excluded pharmacies and pharmacists appear frequently on the LEIE. Document each search with date, list version, names searched, and result. Re-screen monthly or quarterly given direct Part D and Medicaid claims exposure. Include pharmacy vendors in onboarding packets and block formulary or network enrollment until screening clears.
Pharmacy exclusion risk profile
OIG excludes pharmacies and pharmacists for kickbacks, fraudulent billing, and controlled substance violations. Claims for medications dispensed by excluded pharmacies create direct CMP exposure.
Entity and pharmacist screening
Search pharmacy legal name, NCPDP identifiers cross-referenced to name, and DBAs. For independent pharmacies, screen owner-pharmacists individually.
- Pharmacy legal entity and DBA names
- Pharmacist-in-charge for small operations
- PBM entity for managed pharmacy benefits
- State Medicaid exclusion lists
Network and formulary onboarding gates
Complete LEIE screening before adding pharmacies to preferred networks or formularies. Block enrollment until screening clears or false positive is documented.
340B and contract pharmacy considerations
Contract pharmacies in 340B programs require the same LEIE screening as other pharmacy partners. Document screening for every dispensing site in the arrangement.
Recurring monitoring
Pharmacy exclusions mid-contract affect all claims for dispensed medications during the exclusion period. Re-screen active pharmacy partners on your highest-risk schedule.
Audit documentation
Export pharmacy vendor screening logs by network enrollment date and re-screen cycle. Payer pharmacy audits increasingly include LEIE evidence requests.
