Behavioral Health CPT Codes and 2026 Medicare Rates
Most behavioral health billing guidance stops at listing the codes. What decides whether a practice is paid correctly is narrower than that: what each code is actually worth, at what minute one code becomes another, and which combinations a payer will reject on sight. The figures below are 2026 Medicare national amounts for the non-facility (office) setting, before geographic adjustment, with the facility amount shown alongside.
- 90791 — Psychiatric diagnostic evaluation, no medical services. $173.35 non-facility, $137.28 facility.
- 90837 — Individual psychotherapy, 60 minutes. $167.00 non-facility, $135.27 facility.
- 90834 — Individual psychotherapy, 45 minutes. $113.90 non-facility, $91.85 facility.
- 90847 — Family psychotherapy, patient present. $109.55 non-facility, $102.87 facility.
- 90832 — Individual psychotherapy, 30 minutes. $85.84 non-facility, $69.47 facility.
- 90853 — Group psychotherapy. $30.39 non-facility, $24.38 facility.
- 90785 — Interactive complexity, add-on. $14.70 non-facility, $11.69 facility.
These are calculated from CY2026 total RVUs at the finalised conversion factor of $33.40 for practitioners who are not qualifying APM participants. Qualifying APM participants are paid on a conversion factor of $33.57. Both rose from $32.35 in CY2025, which is why most psychotherapy codes are paying between three and nine percent more this year than last. Your own remittance will differ from these figures by your locality’s geographic practice cost index, so treat them as the national floor for comparison, not as a quote.
The minute thresholds that decide which code you may bill
Individual psychotherapy is divided purely by documented face-to-face time. Scheduling, note-writing and waiting-room time do not count toward it.
- Under 16 minutes. Not separately billable as psychotherapy.
- 16 to 37 minutes. Bill 90832.
- 38 to 52 minutes. Bill 90834.
- 53 minutes or more. Bill 90837.
The boundaries are unforgiving in both directions. A 37-minute session is 90832 and a 38-minute session is 90834 — a one-minute difference worth roughly twenty-eight dollars. A 52-minute session is 90834 and a 53-minute session is 90837, a difference of about fifty-three dollars. Practices that pick the code from the appointment slot rather than from the documented clock lose money on the sessions that ran long and invite recoupment on the sessions that ran short.
90837 in particular draws payer attention. Several commercial payers monitor the ratio of 90837 to 90834 across a provider’s panel and open records requests when 90837 dominates. The defence is not to avoid the code; it is to document start and stop times, the specific modality used, the patient’s response, and the plan for the next session. A note reading “45-minute session, supportive therapy” establishes neither the time nor the medical necessity, and it will not survive review.
When the therapist is also the prescriber
This is where a large share of psychiatric claims go wrong. A prescriber who provides both medication management and psychotherapy in the same encounter does not bill an E/M code and a standalone psychotherapy code together. They bill the E/M code and a psychotherapy add-on, selected by the psychotherapy time only.
- 16 to 37 minutes of psychotherapy within the E/M visit. Add-on code 90833.
- 38 to 52 minutes. Add-on code 90836.
- 53 minutes or more. Add-on code 90838.
Billing 90832, 90834 or 90837 alongside an E/M code for the same encounter is not a coding preference that some payers accept — it is a bundling error, and it is one of the most reliable ways to have both lines denied rather than one.
Interactive complexity: what 90785 adds, and when it does not apply
90785 is an add-on for encounters made harder by specific communication factors — a third party who must be involved, a caregiver whose behaviour interferes with the session, a patient who needs an interpreter or play equipment to participate, or the mandated reporting of an event during the visit. It attaches to the diagnostic evaluation and psychotherapy codes and to group psychotherapy. It does not attach to psychotherapy for crisis, and it is not a general difficulty surcharge: a session that was simply demanding does not qualify. At $14.70 it is small, but it is claimed on a large share of behavioral health encounters and it is audited precisely because it is small enough to be added carelessly.
Why Behavioral Health Claims Are Denied More Often Than Medical Claims
Behavioral health denials cluster around a short list of causes, and almost all of them are administrative rather than clinical. Knowing which code you are looking at tells you which workflow failed, and where the fix belongs.
- CO-15 / CO-197 — authorisation missing or lapsed mid-episode. The fix sits in reauthorisation alerts several days before expiry, not on the day.
- CO-16 — missing detail, such as group participant names, telehealth originating site, or incomplete consent. The fix sits in template fields that cannot be left blank at the point of documentation.
- CO-50 — medical necessity not evidenced by the note. The fix sits in symptom-linked, function-linked documentation and recorded progress evidence.
- CO-18 / CO-97 — same-day individual and group, or family and individual, read as a duplicate. The fix sits in correct use of modifier 59 or XE, with the encounters genuinely separated.
- PR-32 — collateral contact or care coordination billed as a therapy session. The fix sits in using 90846 where the patient is absent, and documenting direct contact wherever it is claimed.
- PR-204 — service excluded from the plan, or the benefit is carved out to another administrator. The fix sits in benefit verification at intake, including who administers the behavioral benefit.
- CO-29 — filed past the deadline, usually after a documentation delay. The fix sits in filing-clock tracking that starts at date of service, not at note completion.
- CO-31 — coverage terminated mid-episode. The fix sits in monthly re-verification for any patient in a continuing course of treatment.
The carve-out trap
A patient’s medical benefit and their behavioral health benefit are frequently administered by two different organisations. The card in the patient’s hand names the medical plan; the behavioral claim belongs to a separate behavioral administrator with its own portal, its own authorisation rules, its own fee schedule and its own filing deadline. A clean claim sent to the correct-looking payer is still denied, and the practice usually discovers this weeks later, sometimes past the real administrator’s filing window. Verifying who administers the behavioral benefit — not merely whether the patient is covered — is the single highest-yield check at intake in this specialty.
Telehealth has its own failure mode
Behavioral health carries one of the highest telehealth utilisation rates in medicine, which means it also carries the modifier and place-of-service errors that come with it. A video session billed without the telehealth modifier, or with a place-of-service code that contradicts the modifier, denies as cleanly as a session that never happened. The rules differ between Medicare, Medicaid and commercial payers, and they differ by state, so a single sitewide telehealth policy inside a practice is usually the thing producing the denials rather than preventing them.
Behavioral Health Revenue Cycle Management (RCM)
Billing alone does not protect revenue. Effective behavioral health revenue cycle management ensures predictable cash flow and visibility across the entire lifecycle of a claim.
