Psychiatry and Behavioral Health Billing · All 50 States
Psychiatry billing is billed
by the minute, and denied for the same reason
Psychotherapy CPT codes are time-based. Document the wrong session duration, select the wrong code, or miss an E/M add-on, and the claim is denied before it reaches a reviewer. Zen specializes in the nuanced world of psychiatry and behavioral health billing.

Time-based CPT codes,, the core of psychiatry billing
CPT 90832
16–37 min
Individual psychotherapy, shorter session
CPT 90834
38–52 min
Individual psychotherapy, standard session
CPT 90837
53+ min
Individual psychotherapy, extended session
The documentation trap: Selecting the correct code depends entirely on documented face-to-face time. A session documented as 50 minutes billed as 90837 is an automatic denial — the code requires 53 minutes minimum. When E/M is combined with psychotherapy on the same day, the correct add-on code (90833, 90836, or 90838) must be used or both claims are at risk.
The core GI billing distinction
Screening colonoscopy
Preventive, no symptoms, no history
Billed as preventive care when a patient has no prior findings, no family history triggers, and no current GI symptoms.
-
Covered at 100% under most plans
-
No patient cost-sharing
-
No deductible applied
Diagnostic colonoscopy
Medical, symptoms, history, or findings
Billed as diagnostic when driven by symptoms, a prior finding, family history, or when a polyp is discovered and removed mid-procedure.
-
Subject to deductible and co-insurance
-
Patient cost-sharing applies
-
Each payer has different rules
The billing challenge
Where psychiatry revenue leaks
From time-based coding errors to telehealth place-of-service mismatches — psychiatry billing has more ways to go wrong per claim than almost any other behavioral health specialty.
Duration-based billing errors
Psychotherapy CPT codes are time-based. Incorrect time documentation or wrong code selection, off by even a few minutes, is a top denial driver.
Prior authorization for medication management
Many insurers require prior auth for psychiatric medications, medication management visits, and psychological testing — and denials happen silently when auth lapses.
Telehealth reimbursement mismatches
Post-pandemic telehealth rules vary dramatically by payer and state. Incorrect place-of-service codes trigger systematic denials across entire claim batches.
E/M plus psychotherapy bundling
Billing E/M with psychotherapy on the same day requires correct add-on codes (90833, 90836, 90838). Errors here are common, systematic, and costly.
Mental health parity violations
Payers must cover mental health at the same level as medical benefits under federal law. Many don't. Zen identifies and appeals these violations on your behalf.
Psychological testing billing
Psychological and neuropsychological testing has its own CPT coding structure, medical necessity requirements, and payer-specific coverage rules that differ from therapy billing.

Frequently asked questions
What to expect
How does time-based CPT coding work for psychotherapy?
Psychotherapy CPT codes are selected based on documented face-to-face time. 90832 covers 16–37 minutes, 90834 covers 38–52 minutes, and 90837 covers 53 or more minutes. Correct session time documentation is critical to billing the right code and avoiding downcoding denials.
What is mental health parity and how does Zen enforce it?
Federal parity law (MHPAEA) requires insurers to cover mental health at the same level as medical services. When payers limit psychiatric coverage in ways they would not apply to medical services, visit limits, stricter prior auth, or tighter medical necessity criteria, we identify and appeal those violations on your behalf.
Can Zen handle both in-person and telehealth psychiatry billing?
Yes. We apply the correct place-of-service codes and payer-specific rules for both in-person and virtual visits, ensuring each claim is submitted correctly for how and where the service was delivered.
Is there a long-term contract or commitment?
No. Zen operates month-to-month. We sign a BAA before accessing any PHI. We have built practices from zero and scaled them, we earn your business at every stage.
