Medical Billing Audit
Independent retrospective and prospective billing audits that measure coding accuracy, test documentation strength, quantify revenue leakage, and hand you a prioritized remediation plan.
Medical Billing Audit
A medical billing audit is a structured examination of what your practice actually submitted to payers versus what the medical record supports. ClaimSphere RCM reviews sampled encounters end to end, comparing chart documentation against the CPT, ICD-10, HCPCS, and modifier selections on the claim. The goal is not to assign blame but to show, line by line, where money and compliance protection are being lost.
We run audits in two directions. Retrospective reviews look backward at submitted and adjudicated claims to expose patterns already costing you revenue or creating audit exposure. Prospective reviews inspect coded encounters before they leave the door, so errors are corrected at the source instead of surfacing months later as denials, recoupment demands, or payer inquiries.
What our medical billing audit service includes
Coding Accuracy Review
Certified coders re-adjudicate a representative sample of encounters, validating CPT, ICD-10, HCPCS, and modifier assignment against the record and current payer coding rules.
Documentation Sufficiency Analysis
We test whether provider notes genuinely support each billed service and level, flagging thin documentation, missing medical necessity, and templated language that will not survive payer scrutiny.
Under-Coding and Over-Coding Detection
Our reviewers identify services billed below what the record supports as well as levels that exceed it, correcting lost revenue and inflated risk in the same pass.
Compliance and Audit-Risk Assessment
We benchmark your utilization patterns and error types against payer expectations to surface the exposure most likely to attract a commercial, Medicare, or Medicaid review.
Findings Report and Remediation Plan
You receive a written report quantifying revenue leakage by category, with prioritized corrective actions, staff education points, and follow-up checkpoints to confirm the fixes hold.

Frequently Asked Questions
What is the difference between a retrospective and a prospective audit?
A retrospective audit examines claims already submitted or paid, revealing patterns that have been costing you revenue or creating exposure. A prospective audit reviews coded encounters before submission, so problems are corrected upfront. Most practices benefit from combining both approaches.
How many charts do you review?
Sample size depends on your provider count, specialty mix, and audit objective. A baseline review typically covers a defined number of encounters per provider across your highest-volume service lines. Focused audits targeting a specific code family or payer use narrower, deeper samples.
Will an audit reveal only over-coding problems?
No. Under-coding is just as common and is often more costly. Providers frequently bill conservatively for services their documentation fully supports, quietly forfeiting earned revenue. Our reviews report movement in both directions so you capture legitimate reimbursement while reducing compliance risk.
What do we actually receive at the end?
You receive a findings report covering accuracy rates, error categories, documentation gaps, and estimated financial impact, paired with a remediation plan. We walk your team through the results, answer questions, and can schedule a follow-up review to verify improvement.
