What Is A Medical Billing Audit? 

Medical bill auditing is the process of reviewing billing and clinical records. It checks if the information is accurate, reliable, and follows the right guidelines. The audit also examines the billing documents sent to payers to find errors.

An audit involves handling various documents, like clinical and financial records. It's important to gather all relevant data in one system and keep it well-organized.

By conducting a thorough audit, you can avoid billing issues and ensure you're getting paid correctly.

How to Audit Medical Billing: A Complete Checklist

  • Verify Patient Information

Make sure the details of the patient, like name, birth date, and service dates, are accurate. Cross-check this information with the billing documents. 

It is also important to confirm that the patient's insurance was valid on the service date.

  • Check Provider Information

Ensure that the healthcare provider listed is licensed and authorized to offer services. Review the billing documents to verify the correct provider is listed for each service.

  • Look for Duplicate Records

Check for any duplicate claims or records for the same service date. Review the previous claims to see which codes were paid or denied. 

Ensure no bills were split into multiple claims unnecessarily.

  • Verify Electronic Health Records (EHR)

Make sure patient IDs match across all records. Double-check that the information is complete and accurate. 

Verify that medical history, allergies, and other essential details are accurately recorded.

  • Review Medical History and Visits

Check that all patient visits, exams, and follow-up appointments are listed in order. Ensure each visit includes details from both the primary physician and specialists, as well as the dates and provider information.

  • Verify Diagnostic Reports

Make sure lab tests and imaging results are linked to the correct diagnosis. Ensure reports are complete, signed by the appropriate provider, and contain necessary interpretation details.

  • Check Diagnosis and Treatment Plans

Make sure the final diagnosis matches the treatment plan. Make sure that all lab results and consultant reports support the primary care physician’s findings.

  • Review Procedure Details

Check the records for details about each procedure, like the date and materials used. Confirm that consent forms are signed and that any missed appointments are listed.

  • Verify Medication Records

Check that all prescriptions, including refills, are documented. If a medical device was prescribed, ensure there is a valid prescription. 

Confirm that post-treatment instructions and follow-up details are included.

  • Verify Codes and Billing Formats

Check that the correct CPT and ICD codes are used. Verify that the assigned codes align with medical records. Look for proper modifiers, correct unit billing, and avoid issues like miscoding or upcoding. 

Make sure the billing always complies with payer regulations.
