CPT code 90846: Family psychotherapy (without the patient present), 50 minutes

90846 is used for family psychotherapy sessions where the identified patient is not present for the majority of the session. Meanwhile, 90847 is used for family (conjoint) psychotherapy sessions where the same patient is present with one or more family members.

While the code descriptor specifies 50 minutes, you can bill under 90846 for sessions lasting at least 26 minutes. Accurate documentation of the session start and end times is crucial.

There isn't typically a strict limit, but payers will expect the frequency and duration of sessions to be medically necessary and align with the identified patient's treatment plan and progress. Some payers may have specific limitations on the number of family therapy sessions they cover per year or per episode of care. It's always best to verify with the individual insurance provider.
