In medical billing and CPT coding, several common errors can significantly impact reimbursement. To ensure accuracy and compliance, clinicians and billing specialists should avoid the following mistakes:

  • Incorrect CPT Codes: Always double-check that the selected CPT codes accurately reflect the services provided, especially for specific codes like 90837, 90834, and 90791.
  • Missing or Incorrect Patient Information: Ensure all patient demographics, insurance details, and prior authorizations are complete and accurate to prevent delays.
  • Failure to Document: Proper documentation is crucial; lack of supporting documentation for services billed can lead to denials.
  • Inconsistent Modifiers: Use telehealth modifiers appropriately, as discrepancies can cause claims to be rejected.

By addressing these areas, healthcare providers can improve their billing processes. For further assistance, consider consulting with licensed behavioral health specialists at Array Behavioral Care.
