Laboratory Billing & Coding Audit Services
A laboratory billing audit is an independent review of your coding, claims, denials, payments, and compliance. It quantifies the revenue lost to errors and underpayments, identifies compliance risk, and returns a prioritized plan to correct both.
Why a Laboratory Billing Audit Matters
Routine billing reports show what was paid, not what was missed. An audit surfaces four losses that standard reporting hides: undercoding, unappealed denials, silent underpayments, and compliance exposure.
Hidden Revenue Leakage
Undercoding, missed modifiers, and unbilled tests reduce reimbursement on every claim without appearing as a denial.
Unrecovered Denials and Underpayments
Denied and underpaid claims that were never appealed sit in AR as recoverable revenue.
Compliance Exposure
Coding that does not match medical necessity or CLIA certificate rules creates audit and recoupment risk.
Payer Contract Erosion
Claims paid below the contracted rate go unnoticed without a systematic remittance review.
What a Laboratory Billing Audit Reviews
The audit covers six areas: coding accuracy, medical necessity, denial patterns, underpayments, AR aging, and compliance.
Coding Accuracy
CPT, HCPCS, and ICD-10 accuracy, panel versus component billing, and modifier usage covering 90, 91, QW, and 59.
Medical Necessity
Diagnosis to test linkage checked against Local Coverage Determinations, National Coverage Determinations, and payer policy.
Denial Patterns
Root cause analysis of denial reasons, denial rate by payer, and gaps in appeal recovery.
Underpayment Review
Remittances compared against contracted fee schedules to identify silent underpayments.
AR and Aging
AR aging buckets, days in AR, and the recoverable value held in aged claims.
Compliance and CLIA
CLIA certificate alignment, QW modifier accuracy, HIPAA safeguards, and documentation standards.
Our Laboratory Billing Audit Process
- 01
Data Collection
A representative sample of claims, remittances, denials, and documentation is pulled across payers.
- 02
Coding Review
Certified coders re adjudicate each claim for CPT, HCPCS, ICD-10, and modifier accuracy.
- 03
Denial and Payment Analysis
Denials and payments are analyzed against payer policy and contracted rates.
- 04
Compliance Check
Medical necessity, CLIA alignment, and documentation are tested against CMS and payer standards.
- 05
Findings Report
A prioritized report quantifies revenue leakage, recoverable revenue, and compliance risk.
- 06
Remediation Plan
A step by step correction plan is delivered, with the option for us to implement it.
Types of Laboratory Audits We Perform
Four audit types are available, scoped to what your lab needs.
Coding Audit
A focused review of coding and modifier accuracy across your highest volume tests.
Revenue Cycle Audit
An end to end review of charge capture, claims, denials, AR, and collections performance.
Compliance Audit
A CLIA, medical necessity, and documentation review for audit readiness and recoupment defense.
Payer and Underpayment Audit
A remittance against contract analysis to recover systematically underpaid claims.
What You Receive
Every audit returns three deliverables.
Findings Report
Every issue found, ranked by revenue impact and compliance risk.
Revenue Leakage Estimate
A quantified estimate of annual revenue lost to coding, denial, and underpayment gaps.
Remediation Roadmap
Specific fixes with owners and timelines, ready to implement.
Standards We Audit Against
Findings are measured against the same standards payers and regulators apply.
Results You Can Expect From a Billing Audit
Recovered Revenue
Recoverable denials and underpayments are identified and, where engaged, appealed and collected.
Lower Future Denials
Correcting root cause coding and documentation issues reduces denials on future claims.
Audit Readiness
Coding and documentation brought in line with CMS and CLIA standards reduce recoupment risk.
Protected Payer Yield
Contract level underpayment monitoring protects the rate your lab negotiated.
HIPAA-Compliant Audit Workflows
All audit data is handled under a signed Business Associate Agreement with encrypted transfer and restricted access.
Enterprise Security Infrastructure
AES-256 encryption at rest, TLS encryption in transit, multi factor authentication, and role based access controls.
HIPAA Business Associate Agreement
A signed BAA covering the Privacy Rule, the Security Rule, and the Breach Notification Rule, with annual compliance review.
What Laboratory Providers Say
“The audit paid for itself in the first month. It found underpaid molecular claims we had already written off.”
Molecular Diagnostics Laboratory
“We believed our coding was clean. The audit found modifier and medical necessity gaps that were driving our denials.”
Independent Clinical Laboratory
“Clear findings, quantified impact, and a fix list we could act on rather than a generic report.”

Frequently Asked Questions
What Is a Laboratory Billing Audit?
A laboratory billing audit is an independent review of your coding, claims, denials, payments, and compliance. It quantifies revenue lost to errors and underpayments, identifies compliance risk, and delivers a plan to correct both.
How Do You Find Revenue Leakage?
Revenue leakage is found three ways: a representative claim sample is re adjudicated for coding and modifier accuracy, remittances are compared against contracted fee schedules to catch underpayments, and denial patterns are analyzed for claims never appealed. Each gap is quantified by annual revenue impact.
Will an Audit Help With CLIA and Compliance?
Yes. Coding is tested against medical necessity, Local and National Coverage Determinations, and CLIA certificate requirements, including QW modifier accuracy on CLIA waived tests. Findings reduce recoupment and audit exposure.
How Long Does a Laboratory Billing Audit Take?
A focused coding audit completes within one to two weeks. A full revenue cycle or compliance audit depends on sample size and payer count, and the timeline is confirmed at scoping.
Do I Have to Switch Billing Companies to Get an Audit?
No. The audit is available as a standalone engagement. You receive the findings and the remediation plan regardless of who handles your billing.
Is the Audit HIPAA Compliant?
Yes. All data is handled under a signed Business Associate Agreement with encrypted transfer, restricted access, and audited workflows.
How Much Does a Laboratory Billing Audit Cost?
Cost depends on audit type, claim sample size, and payer count. Many labs choose a fixed fee coding audit or fold the audit into a broader revenue cycle engagement. Pricing is confirmed after a scoping call.
What Do I Receive at the End?
Three deliverables: a prioritized findings report, a quantified revenue leakage estimate, and a remediation roadmap with owners and timelines.
