A MedImpact audit notice puts a pharmacy's reimbursement, network status, and in serious cases its licensure at risk. MedImpact conducts both desk audits, a remote review of submitted claims documentation, and onsite audits, where an auditor examines records and inventory at the pharmacy location, as part of a broader PBM audit program. Findings can range from a minor documentation gap to a recoupment demand for the full ingredient cost and dispensing fee on flagged claims, and unresolved findings can escalate into a network termination review. How a pharmacy responds in the weeks after an audit letter arrives often determines whether a manageable discrepancy turns into a substantial demand.
Desk Audits and Onsite Audits
MedImpact administers two audit formats. A desk audit begins with an audit letter identifying the audit number and the auditor's name, and the pharmacy submits copies of prescriptions, signature logs, wholesaler invoices, and related records by fax, mail, or e-mail. An onsite audit sends a MedImpact-affiliated auditor to the pharmacy to inspect records, inventory, and dispensing practices in person. Both formats can extend into extrapolation, where the auditor applies the error rate found in a small claims sample across the full lookback period, converting a handful of flagged claims into a much larger recoupment demand.
Documentation Standards
MedImpact's audit guidelines direct pharmacies to reference the specific audit number and auditor's name from the audit letter on every submission. Prescriptions, signature logs, wholesaler invoices, delivery confirmations, and prescriber verification should be organized to match each flagged claim line by line, since an unmatched or illegible record is treated the same as a missing one. Pharmacies that deny an auditor's onsite access, or that do not timely submit documentation, risk having MedImpact deem 100 percent of the claims under audit noncompliant, with amounts already paid on those claims immediately due back to MedImpact.
Responding to Discrepancies
When a finding cites a documentation gap rather than a clinical or billing error, the strongest response is a complete, organized rebuttal keyed to each disputed claim, submitted well before the deadline stated in the audit letter. This initial PBM audit response is the pharmacy's best opportunity to narrow or eliminate findings before a final report issues, and it should not wait for the final report to begin. A rebuttal that arrives late, or that addresses claims the auditor did not flag, does not toll the deadline or preserve appeal rights.
Appeal Rights and Deadlines
MedImpact's audit guidelines give pharmacies thirty days from the date of the audit close letter to file a Level 1 appeal and submit new or revised documentation, with a further Level 2 appeal available if the first is denied. A timely, well-documented appeal can reduce or eliminate a recoupment demand before it is finalized. A pharmacy that misses the window forfeits the administrative appeal and is left with contract-based remedies, including any arbitration clause in its provider agreement with MedImpact. Because the deadline runs from the date the close letter is issued, not from when the pharmacy reads it, calendaring that date is essential.
An audit finding that is not challenged within the deadline stated in the close letter becomes final, and a final recoupment demand is far more difficult to unwind than a disputed one.
Why Early Legal Counsel Is Critical
It is critical that pharmacies promptly retain experienced healthcare defense counsel upon receiving a MedImpact audit notice, onsite audit request, or extrapolated recoupment demand. Early legal intervention can protect the pharmacy's rights, ensure appropriate responses to audit requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with the auditor on the pharmacy's behalf. Delaying legal representation can significantly affect the outcome of an audit and expose the pharmacy to unnecessary risk.
