Expert Medical Coding Audit Services That Protect Compliance and Recover Revenue
A professional medical coding audit gives your practice a clear, actionable picture of where revenue is being lost and what needs to change before the problem grows.
- The Problem
Is Inaccurate Coding Quietly Costing Your Practice?
Coding errors do not trigger alarms. They do not appear in your scheduling system. But they accumulate across hundreds of claims every month, and the financial impact is real
Medical coding audits identify these issues before they compound further. They also determine whether your practice is at elevated risk of a payer-initiated review and provide the documentation to address that risk proactively.
The American Medical Association estimates that up to 12% of medical claims are submitted with inaccurate codes.
Practices generating $2 million annually can lose $80,000 or more from undercoding alone, before accounting for denial-driven revenue loss or compliance exposure from overcoding.

What Our Medical Coding Audit Services Include
Medi Billing provides four types of medical coding audits, each designed for a specific stage and purpose. Our team recommends the right approach based on your specialty, claim volume, and risk profile.
Prospective Coding Audits (Pre-Submission)
Charts and codes are reviewed before claims reach payers. This is the most cost-effective way to prevent denials, catch undercoding, and confirm that documentation supports every code selected.
Best suited for practices with high claim volume, recent staffing changes, or a consistent pattern of first-submission denials.
Retrospective Coding Audits (Post-Submission)
A statistically valid sample of submitted claims is reviewed against patient documentation. This type of medical coding audit identifies systemic patterns across your coding team, including which codes are most affected and what targeted training is required.
Best for establishing a coding accuracy baseline or responding to a payer concern.
Focused Audits by Specialty or Payer
The audit scope is narrowed to a specific code set, procedure type, payer, or individual provider.
Best for investigating a spike in denials from one payer, reviewing a new service line, or isolating one provider within a group practice.
Compliance Risk Assessment
A broader evaluation of your coding and billing compliance posture covering code pattern outliers, modifier usage, documentation completeness, and comparison against OIG and payer-specific guidelines.
Best for practices preparing for a Medicare or Medicaid review, or those that want a defensible compliance baseline in place.
Our Medical Coding Audit Process
Every Medi Billing coding audit follows a structured, consistent process with no vague deliverables.
We define the audit parameters with you, including specialty, date range, provider scope, payer focus, and sample size. Sampling methodology is aligned with OIG guidance.
Secure, HIPAA-compliant access to your EHR or practice management system is established. No large file transfers and no PHI outside secured channels.
Certified medical coding auditors review each chart independently. Does the documentation support the codes billed? Are modifiers applied correctly? Are ICD-10 codes current, specific, and properly linked to procedures? Every finding is logged with the billed code, the supported code, and the clinical rationale.
Individual findings are aggregated to surface systemic trends. This step distinguishes a one-time error from a billing system problem that requires structured correction.
You receive a detailed report covering overall coding accuracy rate, error breakdown by category, provider-level findings, payer-specific patterns, estimated revenue impact of undercoding, and a prioritized recommendation list.
Your account manager and lead auditor walk through every finding with your billing or coding team. Every question is answered. You close the call with a clear action plan.
Where errors are systemic, targeted training for coders and providers is delivered remotely and focused on the specific gaps identified in your audit. Follow-up audits at 60 or 90 days measure improvement and drive accountability.
Specialties We Audit
Coding audit risk is specialty-specific. E&M auditing in primary care follows different standards than procedure coding in surgery. Our auditors are assigned by specialty to ensure every chart is reviewed in the proper context.

Why Practices Choose Medi Billing for Coding Audits
Our coding auditors hold active AAPC or AHIMA certifications, including CPC, CCS, and CPCO credentials. You get a specialist who works in your code set every day, not a generalist reviewer.
Most medical coding audits focus only on what you should not be billing. Ours also identifies what you are entitled to bill but are not capturing, turning the audit into a revenue recovery tool alongside a compliance review.
Every written finding is tied to a specific recommendation, a responsible party, and a priority level. You receive a sequenced action plan, not a list of observations to interpret on your own.
We serve solo providers, independent practices, and small group practices. Our audit scope, pricing, and communication approach are designed for practices where the physician is the primary decision maker and time is limited.
All chart access is conducted under an executed Business Associate Agreement. Data is handled within encrypted, access-controlled systems throughout the engagement. No PHI is retained beyond the audit scope.

Frequently Asked Questions
A medical coding audit is a structured review of submitted or pending claims against patient documentation. It verifies that CPT, ICD-10, HCPCS codes, and modifiers accurately reflect what was documented and clinically performed. A complete audit produces a written findings report with specific, prioritized recommendations.
A prospective audit reviews charts before claims are submitted, preventing errors at the source. A retrospective audit reviews claims that have already been submitted, identifying systemic patterns across your coding team and payer mix. Most practices benefit from starting with a retrospective baseline, then implementing prospective auditing for ongoing quality control.
OIG guidance recommends a minimum of 10 charts per provider for a probe audit. A statistically valid random sample typically covers 30 to 50 charts per provider. Focused audits targeting a specific code set may be smaller. Your auditor will explain the sampling methodology chosen and why it is appropriate for your audit purpose.
Yes. A billing company submits the codes it receives. If inaccurate codes are generated upstream by providers or in-house coders, a billing company cannot correct what it does not know is wrong. A medical coding audit creates a quality checkpoint between documentation and claim submission. Even when your billing company handles coding, a periodic independent audit is advisable to verify accuracy from an objective, external perspective.
