What did CPT 90806 change to in 2013?

In 2013, CPT code 90806, which was used for individual psychotherapy sessions of 45-50 minutes, was replaced by two new codes: 90834 and 90837. Code 90834 is for psychotherapy sessions of 45-59 minutes, while code 90837 is for sessions lasting 60 minutes or more. This change was part of a broader update to the coding system to better reflect the duration and complexity of psychotherapy services.
