Psychotherapy billing and coding require accurate CPT code selection, proper documentation, and compliance with payer guidelines to ensure correct reimbursement and reduce claim denials. Common psychotherapy CPT codes such as 90832, 90834, and 90837 are chosen based on session duration, while add-on codes are used when psychotherapy is combined with medication management or E/M services.

Accurate records, including session time, treatment details, and medical necessity, are essential for successful claims and audit protection. Incorrect coding, missing modifiers, and incomplete documentation can lead to denials, delayed payments, and compliance risks. Proper billing practices help behavioral health providers improve revenue cycle efficiency and maintain financial stability.
