Behavioral health RCM that understands therapy and parity.

Behavioral health billing tends to break in the same three spots every time: session notes whose time doesn't match the code that was billed, psychiatry visits that leave the therapy add-on off when therapy actually happened, and health plans that quietly pay mental health benefits less generously than they're supposed to. A prettier clearinghouse dashboard won't fix any of that — knowing the rules cold will.

Psychotherapy time and interactive complexity

Individual psychotherapy is time-based: 90832 (16–37 minutes), 90834 (38–52), 90837 (53+). The clock starts when the therapeutic interaction starts, not when the patient signs in. If the note says "50-minute session" but the content only supports a brief check-in, 90837 will not survive an audit. Interactive complexity add-on 90785 is for communication barriers — interpreter needs, involvement of third parties with guardianship issues, play equipment for kids — not for "the patient was upset."

Psychiatric diagnostic evaluation uses 90791 (no medical services) or 90792 (with medical services). Re-billing 90791 every few months because "we reassessed" is a denial magnet; 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. The psychotherapy minutes must be distinct from the E&M work and documented that way. This is the single most common psychiatry coding error we correct on intake audits.

IOP, PHP, and higher levels of care

Intensive outpatient and partial hospital programs live under payer-specific HCPCS and revenue-code combinations more often than simple CPT pairs. Auth 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 invent a full day.

• Match therapy CPT to documented minutes before the claim leaves — never round up from a 35-minute note 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 — weekly catch-up creates takebacks.

Telehealth and audio-only for BH

Most commercial and Medicare policies still cover psychotherapy via telehealth with the correct POS and modifier, but audio-only rules keep shifting by state and plan. We maintain payer 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 will look fine for a quarter and then collapse when a major Blues plan rolls back audio-only.

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 want taxonomy and rendering NPI combinations that medical claims never see — wrong taxonomy is a silent rejection, not a polite denial letter. We clear those in scrubbing so your therapists are not waiting 45 days to learn the claim never landed.
