What is CPT
90839
?
90839 is a specific CPT code utilized for individual psychotherapy sessions that are time-based, focusing on the provision of therapeutic services aimed at addressing complex and critical mental health issues. This entry will explore the clinical purpose of this code, the expectations surrounding documentation, and key payer considerations. Clinicians are advised to ensure that their clinical notes align with evidence-based interventions, clearly documenting treatment goals, the specific interventions employed, and measurable progress made by the patient. Given that this code is time-sensitive, it is crucial to accurately record the start and stop times of sessions to support the billed duration, thereby ensuring compliance and facilitating reimbursement.
Documentation Tips
When billing for time-based psychotherapy using code 90839, it is essential to meticulously document the start and stop times of each session. Record the specific therapeutic modality used, whether it be Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), or another evidence-based approach, and detail the clinical focus of the session. Include a comprehensive account of the patient's response to the interventions utilized, as well as a clear plan for subsequent follow-up sessions. For any standardized assessment instruments employed during the session, maintain copies of the completed tools as part of the patient's medical record. In the case of telehealth services, ensure that consent for treatment is documented along with details regarding the technology platform used. It is advisable to adopt a consistent documentation structure, such as the SOAP (Subjective, Objective, Assessment, Plan) or DAP (Data, Assessment, Plan) formats, to enhance audit readiness and promote clarity in clinical notes.

Billing Examples
For instance, a clinician may engage in a focused therapy session using Cognitive Behavioral Therapy (CBT) techniques to help a patient manage symptoms of panic disorder. During the session, the clinician documents specific interventions such as exposure techniques and cognitive restructuring, as well as the patient's progress toward established treatment goals, such as reducing the frequency of panic attacks. In this scenario, if the session duration is 60 minutes, the clinician would bill using the 90839 code, ensuring that the total time spent aligns with the time-based requirements of the code. If a session lasts longer than the typical duration, the clinician should accurately reflect this in the billing, potentially utilizing additional time-based psychotherapy codes as appropriate.
Compliance Guidelines
- Prior to billing, verify payer coverage policies and authorization requirements specific to code 90839, as these can vary significantly among insurers.
- It is imperative to document medical necessity thoroughly, linking the provided psychotherapy services to relevant ICD-10 diagnoses to support the rationale for treatment.
- Ensure the correct application of modifiers, such as modifier 95 to indicate telehealth services, and any other modifiers as required by payer guidelines.
- Avoid the practice of upcoding; always select the code that accurately reflects the documented time spent and the level of service provided.
- Conduct regular audits of billing practices and documentation to identify potential areas for improvement, reduce the risk of denials, and enhance overall compliance.
