What is CPT
H2036
?
H2036 is primarily utilized for billing counseling services within the realm of substance use treatment. This entry will delve into the clinical applications of the code, the documentation requirements essential for compliance, and the considerations that providers must keep in mind regarding payer policies. It is crucial for clinicians to ensure that their clinical notes are closely aligned with evidence-based practices. Documentation should clearly outline treatment goals, interventions applied, and measurable outcomes observed during the sessions. In instances where the code is billed based on time, it is important to meticulously document the start and stop times to substantiate the billed duration. This thoroughness not only supports reimbursement but also enhances the quality of care delivered to patients.
Documentation Tips
When billing for time-based psychotherapy sessions under H2036, it is essential to document both the start and stop times of the session. This not only provides clarity for billing purposes but also serves to validate the time spent in therapeutic engagement. Documentation should include the specific therapeutic modality employed, the assessment instruments used, the clinical focus of the session, the patient’s responses, and a clear plan for follow-up. For any standardized assessment tools utilized, retain copies of completed instruments as part of the patient’s medical record. In the case of telehealth services, ensure that consent for telehealth treatment is documented alongside details about the platform used to deliver the service. Utilizing consistent documentation frameworks, such as the SOAP (Subjective, Objective, Assessment, Plan) or DAP (Data, Assessment, Plan) formats, can significantly enhance audit readiness and ensure compliance with payer expectations.

Billing Examples
For instance, a licensed counselor may provide relapse prevention counseling to a client diagnosed with a substance use disorder. During the session, the counselor documents specific triggers that the client identifies, the coping strategies discussed, and any updates made to the treatment plan based on the client’s progress. If the session includes a group therapy component, the counselor must bill for these services separately under the appropriate HCPCS or CPT codes, adhering to the specific payer rules regarding billing for group versus individual therapy.
Compliance Guidelines
- Always verify payer coverage and authorization requirements before rendering services to ensure compliance with billing practices.
- Document medical necessity for all services rendered, ensuring a clear link between the services provided and the appropriate ICD-10 diagnosis codes.
- Apply the correct modifiers as required by payers (e.g., modifier 95 for telehealth services) to facilitate proper billing.
- Avoid upcoding by ensuring that the selected code accurately reflects the documented time and level of service provided during the session.
- Conduct periodic audits of billing practices and documentation to minimize claim denials and enhance the quality of documentation, thereby improving overall compliance.
