Disputing Incorrect Prescriber NPI on Pharmacy Audit: 4-Step Resolution Process

If audited for a claim with wrong prescriber NPI, follow this structured approach:

Step 1: Gather Evidence

• Copy of disputed claim (showing incorrect NPI).
• Prescriber's correct NPI (from NPPES registry).
• Prescriber's active state license verification.
• Signed letter from prescriber confirming NPI error on claim.

Step 2: Submit Written Dispute

Send to audit contractor (certified mail/portal) including:

• Your pharmacy info (NPI, address, contact).
• Prescriber info (name, NPI, license #).
• Claim details (date, Rx #, NDC, incorrect vs. correct NPI).
• Root cause (typo, system error, prescriber change).
• Attached evidence.

Step 3: Follow Up

• Confirm receipt; get tracking/case number.
• Respond promptly to any requests for additional info.
• Document all communications.

Step 4: Appeal if Denied

• Request redetermination/reconsideration per contractor's process.
• Escalate to ALJ hearing if needed (Medicare) or state administrative process (Medicaid/commercial).
• Engage legal counsel for complex/high-value disputes.

Timeliness is critical—appeal deadlines are strict (often 60–120 days).
