Frequently Asked Questions
What is medical billing auditing and why does my practice need it?
Medical billing auditing is a structured review of claims, coding, documentation, and payment posting to identify billing errors, improper payments, and compliance risks. It helps recover missed revenue and reduce denials.
How does an internal medical billing audit differ from a payer audit?
An internal audit is proactive and designed to identify and correct issues before a payer audit occurs. A payer audit is initiated by an insurance company and may result in recoupments.
What does the medical billing audit process look like at Zoo Health?
The process includes consultation, scoping, secure data collection, sampling and claim review, documentation checks, coding analysis, denial review, financial reconciliation, and a corrective action plan.
Can you identify improper payments and recover revenue?
Yes. We quantify improper payments, duplicate claims, and reimbursement deficiencies and can support recovery efforts and appeals.
How often should a practice perform billing audits?
Higher risk specialties often consider quarterly audits while lower risk practices may perform annual audits. Frequency depends on denial rates, payer complexity, and claim volume.
How does medical billing auditing help reduce billing errors and claim denials?
Medical billing auditing reviews medical claims, coding practices, and the full billing process to find billing errors before they lead to claim denials. By identifying coding errors, documentation gaps, and billing mistakes early, healthcare providers can strengthen accurate coding and improve clean claim submission.
What medical records and clinical documentation do you review during billing audits?
We review medical records, clinical records, health records, and medical documentation alongside billing records and financial records to confirm proper documentation, medical necessity, and that services provided match services billed. This includes diagnosis codes, CPT codes, modifiers, and payment posting details when relevant.
