You cannot bill codes 90837 and 90832 together. They are both psychotherapy codes and cannot be submitted for the same session according to the American Psychological Association (APA). It’s recommended to choose one code that most accurately represents the duration of the psychotherapy session. Misuse of these codes could result in billing errors or insurance denials. If you’re unsure, consult with a billing specialist or other professional resources to ensure you’re using the correct codes.
