Medical Billing Audit Services

Recovery-Focused Medical Billing Audit Services for Healthcare Practices

Most billing audits hand you a 40-page PDF and walk away. Ours find the leakage, recover the dollars, and rebuild the workflows that caused the leakage in the first place. As a full revenue cycle management company, we run your medical billing audit services as part of an active billing operation. You see findings, recovery, and prevention inside one engagement. CPMA-certified auditors. HIPAA-compliant by design.

Here’s the difference. Most audit firms can identify the leakage. They can’t recover it. We do both because the team that finds the dollars is the team that works the appeals, resubmits the corrected claims, and chases the payer underpayments until the money lands in your account.

What Makes Us Different

What Makes One O Seven RCM the Best Medical Billing Audit Company for Healthcare Providers

Practices choose One O Seven RCM as their medical billing audit partner because we don’t stop at the findings report. Every audit gets tied directly to recovered dollars, supervised by CPMA-certified auditors, and built around your specialty’s actual audit risk. You always know which findings turned into collected revenue. This audit experience sets us apart.

Audit-to-Recovery Tracked

Most audit firms hand you a PDF and walk away from your practice. We track every finding through to collected revenue, appeal status, or documented write-off. You see exactly which findings turned into dollars in your account.

CPMA-Certified Auditors

Our auditors hold AAPC's Certified Professional Medical Auditor credential. Most audit firms claim "certified coders." That isn't the same thing. CPMA is the audit-specific certification, and every audit at our firm is supervised by one.

Specialty-Specific Audit Risk

Pain management faces different OIG scrutiny than dermatology. Cardiology has different E/M audit triggers than primary care. We audit what actually matters for your specialty's risk profile, not a generic checklist that misses what matters.

Revenue-Attributed Reporting

Most audit reports show error counts and percentages. Useful, but incomplete. Our reports show error counts, percentages, and the dollar value of each finding category, so leadership can prioritize what matters financially first.

Payer Audit Defense Ready

When a RAC, MAC, ZPIC, or commercial payer audit letter arrives, we respond within 4 hours during business days and have audit defense documentation underway within 5 business days. Most response deadlines run 30 to 45 days.

What an Audit Should Deliver

Three Outcomes Every Medical Billing Audit Should Deliver

A medical billing audit is only worth running if it delivers three specific outcomes. Revenue recovery, compliance protection, and process improvement that prevents the same leakage from recurring. Most audits hit one of three. Our medical billing audit services hit all three because we own the full revenue cycle alongside the audit.

Revenue Recovery and Capture

Revenue Recovery: Uncover undercoded services, missed charges, payer underpayments, and denied claims that should have been appealed. Most practices have 5 to 12% of annual revenue sitting in recoverable categories without realizing it. As a full revenue cycle company, we don’t just identify the recovery opportunity. We work the appeals, resubmit corrected claims, and chase payer underpayments until the dollars hit your account.

Compliance and Risk Mitigation

Compliance and Risk Mitigation: Identify documentation deficiencies, coding errors, and billing patterns that expose your practice to OIG audits, RAC recoupments, and payer recovery actions. Our audits review your billing against HIPAA, False Claims Act, Stark Law, Anti-Kickback Statute, and payer-specific requirements. You learn where your risk is before an external auditor or whistleblower finds it. The window between knowing and getting caught is everything.

Process Improvement and Future Prevention

Process Improvement: Analyze denial trends, intake workflows, coding patterns, and authorization processes to fix the root causes of revenue leakage. Generic auditors stop at findings. We rebuild the front-end RCM workflows that caused the findings in the first place. So your next audit doesn’t surface the same problems. This is where one-time audits become ongoing audit-readiness, which is what compliance teams actually want.

Audit Types We Conduct

Types of Medical Billing Audits We Conduct

Different problems need different audit types. A practice losing money to denials needs a denials audit. A practice that just received a payer letter needs audit defense, not a compliance review. Our medical billing audit services cover every audit type your practice may need, conducted by CPMA-certified auditors who specialize in your specialty.

Coding Audit

Examines patient charts for ICD-10 and CPT coding accuracy, confirms medical necessity documentation supports billed services, and identifies upcoding, unbundling, modifier misuse, and E/M errors. Most useful for practices with high denial rates or recent coding staff changes.

Compliance Audit

Reviews billing practices against HIPAA, OIG, False Claims Act, Stark Law, and payer-specific requirements to identify regulatory risk before external auditors find it. Most useful for practices with new payer contracts, ownership changes, or upcoming external audit notifications.

Denials Audit

Analyzes denial patterns across payers, identifies root cause categories, and produces a denial prevention plan tied to your payer mix. Most useful for practices with denial rates above 5% or growing accounts receivable balances aging past 60 days.

RAC, MAC, and ZPIC Audit Defense

Provides documentation production, response strategy, and appeals support when CMS contractors initiate audits against your practice. Most useful when you've received a RAC letter, MAC documentation request, ZPIC inquiry, or commercial payer recoupment notice this month.

Charge Capture Audit

Reviews encounter documentation against billed charges to identify missed services, undercoded procedures, and revenue leakage from incomplete charge capture. Most useful for hospital-based specialties, surgical practices, and multi-provider groups managing high-volume daily encounters across providers.

E/M Coding Audit

Reviews evaluation and management codes for accuracy, documentation support, and compliance with current AMA guidelines and 2021 E/M coding rules. Most useful for primary care, internal medicine, and any specialty billing high E/M volume daily.

Pre-Payment Audit

Reviews claims before submission to prevent denials, rejections, and compliance violations from ever reaching payers. Most useful for new providers, post-credentialing periods, practices recovering from compliance issues, or specialties with high pre-submission error rates historically.

Post-Payment Audit

Reviews previously paid claims to identify underpayments, missed appeals opportunities, and recovery potential within timely filing windows. Most useful for practices with concerns about historical payer underpayments or contract terms not being honored across recent quarters.

Whatever Audit Type You Need, We Tie It to Recovered Dollars

Whether you’ve received a payer letter today or you’re planning ahead for next quarter, we’ll tell you which audit fits in 30 minutes.

The Audit-to-Recovery Framework

Why Choose One O Seven RCM for Medical Billing Audit Services

Most audit firms can run an audit. Few can recover the revenue they find. We’re the only medical billing audit services provider built inside a full revenue cycle management company. That structural difference changes how every audit gets scoped, conducted, reported, and resolved here. Six gaps. Six fixes.

Audit Findings Tied to Collected Revenue

We don’t stop at the findings report. Every leakage point gets connected to recoverable dollars, and we work the recovery as part of the engagement. Generic auditors hand you a PDF.

Specialty-Specific Audit Risk Profiles

Cardiology has different audit triggers than primary care. Pain management has different OIG scrutiny than dermatology. We audit what actually matters for your specialty’s risk profile, not a generic one-size-fits-all checklist.

Certified Auditors with Real Billing Experience

Our auditors hold AAPC CPMA, CPC, AHIMA CCS, and HFMA CRCR certifications. More importantly, they’ve worked inside billing departments, not just audit firms. So our recommendations are practical, not theoretical or untested.

Revenue-Attributed Audit Reporting

Most reports show error counts and percentages. Ours show error counts, percentages, and the dollar value attached to every finding category, so leadership prioritizes what matters financially first across the engagement.

Front-End RCM as Audit Prevention

Slow eligibility verification, prior auth friction, and weak denial management cause most revenue leakage our audits surface. We rebuild the front-end RCM workflows so the next audit doesn’t surface the same problems.

One Provider for Audit, Billing, and Recovery

You stop juggling audit firms, billing companies, and appeals vendors who point fingers when revenue goes missing. One contract. One team. One number to call when a payer letter shows up.

How Our Audits Work

Our 5-Stage Audit-to-Recovery Process

Every medical billing audit services engagement follows the same 5-stage process. From scope definition to recovery confirmation, you always know what’s happening, what comes next, and what we’ve recovered so far. No black-box audits. No surprise fees. No mystery findings.

Scope Definition and Sample Selection

We define the audit scope and select a statistically valid sample based on your practice size, specialty, and risk areas. Most engagements audit 10 to 30 records per provider across high-volume CPT codes. You approve before review begins.

Documentation and Coding Review

Certified auditors conduct line-by-line analysis against submitted codes. We review documentation support, medical necessity, modifier accuracy, E/M coding, and payer requirements. Every finding cites CMS, AMA, and payer policy guidelines under HIPAA-compliant access protocols throughout.

Findings Report and Recovery Plan

You receive findings with error categories, frequency, and root cause analysis. The recovery plan shows which findings are recoverable, which represent compliance risk, and the dollar value of each category. Most audit firms stop here. We don't.

Active Recovery and Appeals

We resubmit corrected claims, file appeals on denied claims, pursue payer underpayments where contract terms weren't honored, and document legitimate write-offs. Most engagements recover 30 to 60% of identified leakage within the first 90 days of work.

Process Fixes and Ongoing Monitoring

We rebuild eligibility verification protocols, coder training, prior authorization tracking, and denial management procedures. Then ongoing monitoring catches future leakage at the source, not at the next audit. This is how audits become continuous audit-readiness across the practice.

Onboarding Starts with a 30-Minute Audit Scope Call

We’ll review your billing operation, recommend the right audit type, and tell you which findings categories likely hold the most recoverable revenue today.

Specialty Audit Coverage

Medical Billing Audit Services for Every Specialty and Practice Type

Different specialties have different audit risk profiles. A cardiology practice has different high-risk CPT codes than a dermatology practice. A pain management group faces different OIG scrutiny than a pediatric clinic. Our specialty audit teams know the audit triggers, payer behavior, and documentation requirements specific to each vertical. Pick your specialty below.

Pain Management Medical Billing Audits

Pain management audits face the highest OIG scrutiny in all of healthcare today. Our auditors review epidural injection coding, facet joint injection billing, nerve block procedures with separate fluoroscopy guidance charges, and modifier 25 and 59 application across all interventional procedures. Recurring auth denials, modifier overuse patterns, and medical necessity gaps get flagged before external auditors find them at your practice doorstep.

Hospital Inpatient and Outpatient Audits

Hospital audits cover DRG coding for inpatient claims, APC coding for outpatient claims, and complex multi-encounter billing across service lines. Our auditors review patient accounting systems, Medicare Part A and Part B billing splits, and hospital-physician billing coordination thoroughly. CPMA-certified auditors handle DRG validation, principal diagnosis sequencing, and APC packaging logic unique to hospital billing operations on every audit engagement we run.

Cardiology Medical Billing Audits

Cardiology audits cover complex E/M coding, cardiac procedure billing, and high-volume commercial payer denial patterns we see weekly. Our auditors review E/M leveling logic across new and established patient visits, stress test billing with separate professional and technical components, and EKG and echocardiogram coding under AAPC-certified supervision. Cardiac imaging prior auth documentation gets reviewed for audit defensibility on every single audit engagement.

Multi-Specialty Practice Medical Billing Audits

Multi-specialty practice audits handle the highest cross-specialty audit risk in all of healthcare today. Our auditors review billing across cardiology, orthopedics, primary care, and dermatology inside the same audit engagement. Specialty-specific modifier conventions, CPT patterns, and payer behavior shift across providers in the same practice daily. CPMA-certified auditors maintain accuracy across mixed-payer environments without losing specialty-specific audit depth across provider lines ever.

DME Suppliers and Home Health Agency Audits

DME and home health agency audits face the strictest documentation compliance requirements in all of healthcare today. Our auditors review face-to-face encounter documentation, certificate of medical necessity forms, plan of care signatures, OASIS accuracy, and homebound status documentation against CMS requirements thoroughly. Documentation gaps that trigger RAC audits or commercial payer recoupments get flagged before external auditors arrive at your practice doorstep.

External Audit Defense

RAC, MAC, ZPIC, CERT, and TPE Audit Defense

Most providers don’t think about external audits until they receive a payer letter. By then, the documentation gaps and coding errors have already happened. Our medical billing audit services include audit defense and pre-audit hardening for every type of CMS contractor audit your practice may face today.

RAC Audits (Recovery Audit Contractors)

Focus on identifying improper payments to providers. Compensation-based contractors paid a percentage of overpayments recovered. Most common audit type across all CMS regions. Risk areas include high-dollar claims, complex coding, and unusual billing patterns inconsistent with peer providers.

MAC Audits (Medicare Administrative Contractors)

Process Medicare claims and conduct routine audits. Detect billing patterns inconsistent with peer providers. Risk areas include CERT-flagged providers, high E/M volumes, modifier overuse, and unusual claim frequency patterns flagged through CMS data analytics review systems daily.

ZPIC Audits (Zone Program Integrity Contractors)

Target suspected fraud, not random sampling. On-site inspections are common during ZPIC review. Risk areas include whistleblower tips, data analytics anomalies, referral patterns from MAC findings, and outlier billing volumes compared to specialty peer averages reported regionally.

CERT Audits (Comprehensive Error Rate Testing)

Evaluate MAC processing accuracy through provider sampling. Document requests sent to randomly selected providers across regions. Failure to respond triggers automatic escalation. Risk areas include incomplete documentation responses, pattern errors across claims, and missed response deadlines.

TPE Audits (Targeted Probe and Educate)

Three-round audit-and-education cycles for providers flagged with high error rates by MACs. Designed as corrective rather than punitive enforcement. Risk areas include providers flagged for repeated denials, modifier issues, or documentation patterns inconsistent with Medicare guidelines.

What is a medical billing audit?

A medical billing audit is a structured review of a healthcare provider’s billing practices, coding accuracy, claims data, and documentation to identify revenue leakage, compliance risk, and process improvements. Audits compare submitted claims against documentation and payer rules to find errors, underpayments, and missed charges. Internal audits are conducted by in-house staff. External audits use independent firms for objective findings and stronger defense.

What are medical billing audit services?

Medical billing audit services are specialized engagements where certified auditors review your billing operations, claims, coding, and documentation against payer rules and compliance requirements. They include coding audits, denials audits, charge capture reviews, compliance audits, and audit defense. The best medical billing audit services don’t just identify findings. They recover the lost revenue and rebuild the workflows that caused the leakage in your practice.

How much does a medical billing audit cost?

Medical billing audit services cost varies by audit scope, practice size, and audit type. Focused audits for small practices typically run in the low four figures. Comprehensive audits for multi-provider groups run mid-four figures into low five figures. Hospital and health system audits scale higher based on enterprise scope. Every One O Seven RCM engagement starts with a free scope consultation and custom proposal.

How long does a medical billing audit take?

A medical billing audit typically takes 4 to 6 weeks from scope definition to final report. Smaller focused audits complete in 2 to 3 weeks. Hospital and multi-specialty group audits can take 8 to 12 weeks for full comprehensive review. Recovery and process remediation continue beyond the audit timeline, typically running 60 to 120 days for full execution across active appeals and resubmissions.

How often should medical billing audits be performed?

Most healthcare providers should conduct comprehensive medical billing audits at least annually. Practices with high claim volumes, recent staff changes, denial rates above 5%, or compliance concerns benefit from quarterly or semi-annual audits instead. New providers should be audited within their first 90 days of operation. Continuous audit-readiness, where small audits run quarterly, is the standard for compliance-mature practices today.

What is the difference between internal and external medical billing audits?

Internal medical billing audits are conducted by in-house staff. They’re cheaper and faster but lack objectivity and broad benchmarking against industry data. External audits use independent firms for objective findings, broader benchmarking, and stronger defense if findings are challenged later. Most practices benefit from a hybrid approach: internal monthly samples plus external comprehensive audits annually for documented compliance posture across the operation.

What audit findings are most common in medical billing?

The most common medical billing audit findings include upcoding, unbundling, modifier misuse, missing documentation to support medical necessity, undercoded E/M services, missed charges, payer underpayments, and denied claims that should have been appealed. Process-level findings include weak eligibility verification, prior authorization gaps, and inconsistent denial management. Most practices have 5 to 12% of revenue exposed to these specific categories without realizing it.

What is a RAC audit?

A RAC audit is a Recovery Audit Contractor review conducted by CMS-contracted firms to identify improper Medicare payments to healthcare providers. RACs receive a percentage of overpayments they recover, which incentivizes thorough review of high-value claims. Risk areas include high-dollar claims, complex coding, and billing patterns inconsistent with peer providers. RAC audits typically begin with a documentation request letter sent to your practice.

What makes One O Seven RCM different from other medical billing audit companies?

One O Seven RCM is the only medical billing audit firm built inside a full revenue cycle management company. Our Audit-to-Recovery framework ties audit findings directly to recovered revenue inside the engagement. We don’t just identify the leakage. We work the appeals, resubmit corrected claims, and recover the dollars as part of the audit. We also rebuild front-end RCM workflows to prevent future leakage.

Are your medical billing audits HIPAA-compliant?

Yes. Every medical billing audit we conduct is HIPAA-compliant by design from day one. We sign Business Associate Agreements before any engagement begins. We use encrypted access, role-based audit trails, and PHI-safe workflow protocols throughout. We comply with HIPAA Privacy and Security Rules, HITECH Act, and applicable state-specific patient privacy laws. Compliance is built into every stage of the audit.

Can a medical billing audit help prevent payer audits?

Yes. Proactive medical billing audit services identify and correct issues before external auditors find them at your practice. Continuous internal audits demonstrate due diligence to compliance officers, payers, and OIG investigators if questioned later. Practices with documented audit programs face fewer external audits and resolve any external audits faster. Continuous audit-readiness is the strongest defense against RAC, ZPIC, and OIG actions.

How do I get started with One O Seven RCM medical billing audit services?

Start with a free 30-minute scope consultation. We review your current billing operations, claims volume, denial patterns, and audit goals. Within one week, you receive a written audit scope proposal with timeline and pricing. If you proceed, we sign a Business Associate Agreement and begin scope definition immediately.
