Types of Medical Billing Audits

There are two main types of medical billing audits in the US:

  • Prepayment Audits: These audits occur before a claim is paid by the insurer. They focus on verifying patient eligibility, service necessity, and coding accuracy.
    • Internal Audits: These audits are conducted by the healthcare organization’s own staff or a third-party auditor hired by the organization. These audits are proactive measures to identify and rectify issues before external audits.
    • External Audits: These audits are conducted by external entities such as insurance companies, Medicare, or Medicaid. These audits are typically more rigorous and can result in significant penalties if discrepancies are found.
  • Post Payment Audits: These audits happen after a claim has been paid. They delve deeper into a sample of claims to identify any billing errors or discrepancies.
    • Prospective Audits These audits are conducted before claims are submitted to payers. The focus is on preventing errors and ensuring that all claims are accurate and compliant from the outset.
    • Retrospective AuditsThese audits are conducted after claims have been submitted and processed. The primary goal is to identify and correct any errors or discrepancies in the billing records.
