What is CPT
90785
?
90785 is a CPT code that is utilized primarily for the provision of interactive complexity within psychotherapy services. This entry provides an overview of the clinical applications of this code, the documentation requirements necessary for billing, and crucial payer considerations. It is essential for providers to ensure that their clinical documentation aligns with evidence-based practices, explicitly detailing treatment goals, the interventions employed, and measurable outcomes. When billing this code is time-dependent, it is critical to accurately record the start and stop times to substantiate the duration of the service provided.
Documentation Tips
When billing for time-based psychotherapy services using code 90785, it is essential to document the start and stop times meticulously. In addition to time records, include a description of the therapeutic modality utilized, the assessment instruments administered, the clinical focus of the session, the patient’s responses, and a detailed plan for follow-up interventions. For assessments involving scored instruments, maintain copies of completed tools within the patient’s record. In instances of telehealth services, ensure that consent from the patient is documented along with the details of the platform used for service delivery. Utilizing consistent documentation frameworks such as the SOAP (Subjective, Objective, Assessment, Plan) or DAP (Data, Assessment, Plan) formats can enhance audit readiness and support compliance efforts.

Billing Examples
Clinical interactions should consistently connect findings to the overall treatment planning, emphasizing measurable goals.

Documentation should demonstrate clinical necessity for each billed code, providing a clear narrative that supports the services rendered.
