It’s tempting to view the final report of a healthcare claims audit as the finish line. After weeks of data collection, analysis, and review, the findings are delivered, recoveries are identified, and the project appears complete.

In reality, the greatest value begins after the report is delivered.

The best healthcare claims audits do more than identify payment errors. They reveal recurring issues and opportunities to improve how a health plan is administered. The greatest value comes from acting on those findings.

Before discussing what happens after a healthcare claims audit, it helps to understand what the audit is designed to accomplish.

A healthcare claims audit is a structured review of medical and pharmacy claims alongside plan documents, eligibility records, payment data, and administrative processes. Auditors compare claims against plan provisions to verify payment accuracy, measure financial impact, and identify patterns that may point to broader operational or administrative gaps.

Rather than viewing each claim in isolation, auditors evaluate findings across the health plan to distinguish isolated mistakes from systemic issues. The goal isn’t simply to determine whether claims were paid correctly; it’s to understand why errors occurred, where corrective action is needed, and how similar issues can be prevented in the future.

The scope of the review matters. Audits based on limited samples may identify individual errors, while comprehensive reviews can reveal patterns and systemic issues that sampling may miss. Healthcare Horizons reviews 100% of medical and pharmacy claims to provide a more complete view of recurring issues and opportunities for improvement.

The findings are compiled into a comprehensive audit report that summarizes payment discrepancies, financial recoveries, recurring issues, and opportunities for improvement. The report gives organizations a clear picture of how their health plan is performing and where attention should be focused. (For a behind-the-scenes look at the audit process, read our interview with Healthcare Horizons Operations Manager, Brylee Trew.)

For many audit firms, that’s where the engagement ends.

For organizations committed to improving health plan performance, it’s where the real work begins.

The healthcare claims audit report should mark the beginning of the improvement process, not the end of it. While every health plan has different priorities, the most effective post-audit efforts typically focus on five areas.

The first priority is recovering identified overpayments and payment discrepancies. Depending on the audit findings, this may include duplicate payments, coordination of benefits (COB) errors, eligibility issues, incorrect reimbursement amounts, or claims paid outside the terms of the health plan.

Recoveries often require coordination between the employer, third-party administrator (TPA), providers, and the audit firm to validate findings, pursue reimbursement, and document the financial impact. Organizations should also track recoveries to ensure identified overpayments are recovered and to measure the audit’s financial impact.

Even small payment inaccuracies can add up over time. According to healthcare advisory firm Withum, overpayment recoveries can represent approximately 1% to 1.5% of total claims paid. Without a structured recovery process and ongoing oversight, those dollars may never make their way back to the health plan.

Recovering an overpayment answers what happened. Root cause analysis answers why it happened.

Rather than treating each claim as an isolated error, organizations should determine whether multiple findings point to a common underlying issue. For example, recurring payment discrepancies may stem from a system configuration, an incorrectly loaded provider contract, inconsistent interpretation of plan language, incomplete eligibility data, or a breakdown in administrative workflows.

Correcting a single underlying issue can eliminate dozens — or even hundreds — of recurring claim errors. That’s why healthcare compliance guidance increasingly identifies root cause analysis (RCA) as the foundation of effective corrective action. Rather than simply correcting individual findings, organizations are encouraged to identify the underlying process or system breakdowns that allowed those issues to occur in the first place.

Once root causes have been identified, organizations can begin implementing corrective actions. This phase is typically led by the TPA and administrative teams responsible for day-to-day claims processing, working in collaboration with the employer and audit partner.

Corrective actions may include:

• Update claims processing workflows
• Refine system configurations or payment rules
• Improve eligibility file management
• Clarify staff responsibilities
• Provide additional training for recurring issues
• Add quality assurance or validation checkpoints

The objective is to improve how claims are processed going forward — not simply correct the claims that have already been paid. 

Healthcare claims audits frequently expose systemic patterns in claims processing, system configuration, and administrative workflows rather than isolated human errors. The greatest value comes from translating those findings into documented process improvements with clear ownership and follow-up.

Not every audit finding points to an operational issue. Some reveal opportunities to strengthen the health plan itself.

Audit findings may prompt employers, brokers, consultants, and benefits leaders to clarify plan language, refine vendor expectations, strengthen performance guarantees, or update administrative policies.

The findings also provide objective data for contract renewals and performance discussions with TPAs or PBMs. Employers can use that information to evaluate whether vendors are meeting their obligations and administering the plan as intended.

Over time, these decisions improve accountability, strengthen oversight, and support better health plan performance.

Implementing corrective actions is only part of the process. Organizations should also evaluate whether those changes produced the intended results.

Monitoring may include:

• Review whether recurring claim errors have declined
• Confirm that agreed-upon process changes were implemented
• Track identified overpayment recoveries through completion
• Evaluate whether vendors are meeting contractual obligations
• Watch for new trends or emerging risks

These follow-up reviews help determine whether corrective actions addressed the underlying cause and produced lasting improvements. They also identify new risks before they become larger operational or financial problems.

Future audits build on this work by measuring progress over time rather than starting from scratch, helping organizations continuously strengthen health plan performance.

A healthcare claims audit doesn’t improve a health plan simply because a report is delivered. It improves a health plan when organizations act on its findings.

Recovering overpayments is an important first step, but it’s only part of the story. The greatest long-term value comes from identifying root causes, improving administrative processes, strengthening plan oversight, and measuring whether those changes continue to deliver results.

At Healthcare Horizons, that’s the philosophy behind every audit. By reviewing 100% of medical and pharmacy claims and focusing on the underlying causes of recurring issues, Healthcare Horizons helps organizations move beyond identifying payment errors to making meaningful, lasting improvements in health plan performance.

The audit report isn’t the finish line. It’s where the greatest value begins.
