Behavioral health RCM built for therapy, psychiatry, and parity rules.

Behavioral health billing usually breaks in three places: notes whose minutes do not support the CPT billed, psychiatry visits that omit the therapy add-on when therapy occurred, and plans that pay mental health benefits less generously than medical/surgical benefits allow. A cleaner dashboard does not fix those gaps. Rule knowledge and disciplined scrubbing do.

Psychotherapy time and interactive complexity

Individual psychotherapy is time-based: 90832 (16–37 minutes), 90834 (38–52), 90837 (53+). The clock starts when therapeutic interaction begins, not at check-in. If the note says “50-minute session” but the content only supports a brief check-in, 90837 will not survive review. Interactive complexity add-on 90785 is for defined communication barriers — interpreter needs, third-party involvement with guardianship issues, play equipment for children — not for “the patient was distressed.”

Psychiatric diagnostic evaluation uses 90791 (no medical services) or 90792 (with medical services). Rebilling 90791 every few months because “we reassessed” draws denials; most payers limit frequency unless there is a clear clinical change or a new episode of care.

E&M plus psychotherapy on the same day

When a psychiatrist or NP performs a medical E&M and psychotherapy in the same encounter, bill the E&M plus the psychotherapy add-on: 90833 (16–37 min), 90836 (38–52), or 90838 (53+). Do not bill a standalone 90834 on top of a 99214 for the same face-to-face time. Psychotherapy minutes must be distinct from E&M work and documented that way. This remains the most common psychiatry coding correction we make on intake audits.

IOP, PHP, and higher levels of care

Intensive outpatient and partial hospital programs often use payer-specific HCPCS and revenue-code combinations rather than simple CPT pairs. Authorization periods, concurrent review, and discharge summaries drive payment as much as the daily code. Bill units that match the attendance log. If the patient left after two hours of a six-hour PHP day, do not bill a full day.

• Match therapy CPT to documented minutes before submission — never round a 35-minute note up to 90837.
• Use 90785 only when interactive complexity criteria are explicit in the note.
• Pair psychiatry E&M with 90833/90836/90838 when therapy is performed; never double-dip with 90834.
• For IOP/PHP, reconcile census, auth dates, and billed units daily.

Telehealth and audio-only for behavioral health

Most commercial and Medicare policies still cover psychotherapy via telehealth with the correct POS and modifier, but audio-only rules continue to shift by state and plan. We maintain matrices for POS 02 vs 10, modifiers 95 and 93, and which plans still allow telephone-only 90832–90837. Behavioral health RCM that ignores those matrices can look stable for a quarter, then stall when a major Blues plan changes audio-only policy.

Group therapy (90853) and family therapy (90846/90847) have their own unit and presence rules. Document who attended and for how long. Medicaid behavioral health carve-outs often require taxonomy and rendering NPI combinations that medical claims never see — wrong taxonomy is often a silent rejection. We clear those in scrubbing so therapists are not waiting weeks to learn the claim never landed.
