  • Use specialty-specific codes: When applicable, use specialty-specific codes that accurately describe the specialist therapies performed, as they may be compensated

Tips for Documentation to Support Billing Options

Accurate documentation is crucial in supporting the billing codes used, ensuring that claims pass through insurance inspection without being rejected.

  • Detailed Treatment Notes: Keep extensive notes for each session that clearly support the billing code. Include the duration of the treatment, the strategies utilized, and how the patient responded to the treatment.
  • Consistency in Documentation: Make sure that the treatment notes match the billing codes submitted. Inconsistencies between clinical notes and billing codes are a typical cause of claim denial.
