Pharmacy Benefit Managers (PBMs) and insurance companies hold enormous power over a pharmacy’s ability to operate. With most pharmacies relying on third-party payors, one audit - whether from a PBM, an insurance plan, Medicare Part D sponsor, or a commercial payer - can threaten reimbursements, trigger massive recoupment demands, or even jeopardize network participation.
PBM audits have become more frequent, more aggressive, and more complex. Many pharmacies don’t realize how much is at risk until an audit notice arrives.
This guide breaks down why PBM audits happen, what auditors look for, and how the right legal strategy can protect your pharmacy's financial and professional future.
What Is a PBM Pharmacy Audit?
A PBM audit is a review of a pharmacy’s claims, records, billing practices, and dispensing procedures to determine whether reimbursement was accurate and compliant with PBM contract requirements. PBMs conduct these reviews to check for errors, potential fraud, or overbilling—even when the issues are minor or unintentional.
Audits usually fall into three main types:
- Desk audits (document-only reviews)
- Onsite audits (in-person, often unannounced)
- Virtual audits (a mix of desk and real-time verification)
Regardless of the format, all audits share the same goal: finding discrepancies the PBM may use to deny or recoup payments.
Why PBMs and Insurance Companies Conduct Audits
Audits aren’t always triggered by wrongdoing. Many pharmacies are selected at random. Others are flagged by algorithms that look for patterns or anomalies.
Common triggers include:
- High-volume billing of certain medications
- Claims involving controlled substances
- Unusual refill patterns
- Discrepancies in prescriber information
- Incomplete or inconsistent patient records
- Missing signatures, delivery logs, or hard copies
Even minor clerical mistakes can lead to major financial penalties because PBMs often apply strict—sometimes unrealistic—interpretations of their own contracts.
What PBM Auditors Look for During a Review
Pharmacies often feel blindsided by the depth of scrutiny they face. Auditors frequently examine:
- Dispensing records and signature logs
- Purchase histories compared to claims (“drug utilization vs. acquisition cost”)
- Inventory and ordering patterns
- Prior authorization documentation
- Prescriber credentials and DEA validation
- Refill protocols and timing
One missing document—even if the prescription was properly dispensed—can be grounds for recoupment.
What Happens After a PBM Audit?
At the end of the audit, the pharmacy receives a report outlining alleged discrepancies. These reports can include:
- Requests for repayment of reimbursements
- Accusations of overbilling
- Findings of noncompliance with PBM policy
- Threats of network suspension or termination
Many pharmacists assume these findings are final. They are not. You have the right to challenge them—and success often depends on having an attorney familiar with PBM contracts and audit procedures.
How an Attorney Can Protect Your Pharmacy During a PBM Audit
PBM audits are built on technicalities. A pharmacy-defense attorney at Callahan Law understands how PBMs operate, what they’re allowed to do, and where their findings can be challenged.
Our Team can help by stepping in early to review your PBM contracts, correct misunderstandings, communicate with auditors, and make sure you don’t inadvertently say something that harms your case. They can also gather documentation, prepare written responses, and identify where the PBM’s conclusions don’t align with actual records or industry standards.
If the PBM demands recoupment or proposes network termination, legal counsel can negotiate on your behalf and push back against penalties that are excessive or unsupported. When licensing or DEA concerns overlap with PBM issues, an attorney can coordinate a unified strategy to protect both your license and your business.
Pre-Audit Preparation: One of the Best Defenses You Have
Many problems can be avoided long before an audit starts. Pre-audit legal reviews help pharmacies:
- Identify contract terms that commonly cause disputes
- Verify that documentation is complete and compliant
- Strengthen policies and procedures
- Prepare staff for auditor interactions
- Correct small issues before they become major findings
Pharmacies that prepare in advance typically face fewer penalties and recover far more successfully from audit challenges.
Post-Audit Guidance and Recoupment Defense
Once an audit report is issued, time is limited. A pharmacy must respond quickly and accurately. An attorney can:
- Review the findings
- Challenge inaccurate or unsupported conclusions
- Provide additional documentation
- Prepare appeal submissions
- Negotiate repayment amounts
- Fight to prevent network termination
Without representation, pharmacies often overpay or accept audit findings they could have contested.
