Behavioral Health CPT Codes: The Complete List for 2026
If you've ever submitted a claim only to have it bounce back — wrong code, wrong modifier, wrong place of service — you already know that CPT coding in behavioral health is not a "set it and forget it" skill. It's a living, shifting system that directly determines how much you get paid, how quickly, and whether you survive a payer audit.
This guide is your definitive reference for every behavioral health CPT code that matters in 2026. Whether you're a solo therapist in private practice, an LMFT working in a group practice, or a psychiatrist managing a hybrid medication-management and psychotherapy caseload, this is the guide you'll want to bookmark.
We'll cover psychotherapy codes, evaluation and management (E/M) codes, psychological and neuropsychological testing, crisis intervention, telehealth modifiers, and the compliance landmines you need to avoid. Let's get into it.
Why CPT Codes Matter More Than Ever in 2026
Payers are getting smarter — and so are their auditors. UnitedHealthcare, Aetna, Cigna, and Optum have all increased their pre-payment review activity for behavioral health claims over the past two years. The AMA updates CPT codes annually, and CMS continues to refine its Medicare Physician Fee Schedule, which directly influences what commercial payers reimburse.
In 2026, two trends are reshaping how behavioral health codes get used:
- Telehealth parity enforcement — More states are requiring commercial payers to reimburse telehealth at the same rate as in-person services, which has made modifier selection even more critical.
- Documentation scrutiny — Payers like Cigna and BCBS are requesting clinical notes more frequently to validate time-based codes like 90837 and add-on codes like 90785.
Getting your codes right isn't just about revenue — it's about compliance. A miscoded claim that gets paid is a liability. Let's make sure every code you submit is defensible.
The Core Behavioral Health CPT Code Categories
1. Psychotherapy Codes (90832–90838)
These are the workhorses of outpatient behavioral health billing. They're time-based, which means your documentation must clearly reflect the time spent in face-to-face psychotherapy.
| CPT Code | Service Description | Typical Session Length | 2026 Medicare Rate (approx.) |
|---|---|---|---|
| 90832 | Psychotherapy, 30 min | 16–37 minutes | ~$83 |
| 90834 | Psychotherapy, 45 min | 38–52 minutes | ~$112 |
| 90837 | Psychotherapy, 60 min | 53+ minutes | ~$152 |
| 90839 | Psychotherapy for crisis, 60 min | First 60 min | ~$213 |
| 90840 | Psychotherapy for crisis, add-on | Each additional 30 min | ~$107 |
Key compliance tip: The "typical session length" ranges above are the AMA's time thresholds. If you document a 45-minute session and bill 90837, you're inviting a claim denial or worse. Your note must reflect 53+ minutes of face-to-face psychotherapy time to bill 90837 — not just "time in office."
2. Psychotherapy Add-On Codes
Add-on codes are billed in addition to a primary service. You cannot bill them standalone.
| CPT Code | Description | Common Pairing |
|---|---|---|
| 90785 | Interactive complexity | 90832, 90834, 90837 |
| 90833 | Psychotherapy, 30 min with E/M | E/M code (99202–99215) |
| 90836 | Psychotherapy, 45 min with E/M | E/M code |
| 90838 | Psychotherapy, 60 min with E/M | E/M code |
90785 — Interactive Complexity is one of the most under-billed add-on codes in outpatient behavioral health. You can add it when your session involves things like:
- A third-party present (parent, guardian, translator)
- A patient with communication barriers
- Mandated reporting issues that arise during the session
- A patient in crisis with multiple agencies involved
Many therapists leave $15–25 per session on the table by not billing 90785 when it clearly applies.
90833/90836/90838 are used by psychiatrists and prescribers who conduct both a medical E/M visit and psychotherapy during the same encounter. This is common in psychiatric practice where a 60-minute appointment involves medication management and psychotherapy. The time for the E/M and the psychotherapy must be documented separately.
3. Psychiatric Evaluation Codes (90791 & 90792)
| CPT Code | Description | Who Bills It | 2026 Medicare Rate (approx.) |
|---|---|---|---|
| 90791 | Psychiatric diagnostic evaluation | Non-prescribing clinicians (LPC, LCSW, LMFT, psychologist) | ~$178 |
| 90792 | Psychiatric diagnostic evaluation with medical services | Prescribing clinicians (MD, DO, NP, PA) | ~$232 |
These codes are for initial evaluations only — not for ongoing sessions. A common audit red flag is billing 90791 more than once per patient per episode of care without a clearly documented clinical justification (e.g., new episode after a significant gap in treatment).
Both codes require a comprehensive note: chief complaint, psychiatric history, mental status exam (MSE), DSM-5-TR diagnosis, and a treatment plan. If your intake note doesn't have all five of those elements clearly documented, you're exposed.
4. Evaluation & Management (E/M) Codes for Psychiatry (99202–99215)
Psychiatrists and prescribing practitioners use E/M codes for medication management visits. These follow the AMA's 2021 E/M guidelines, which are still in effect for 2026 and base level selection on either medical decision making (MDM) or total time.
New Patient E/M Codes
| CPT Code | MDM Complexity | Total Time | 2026 Medicare Rate (approx.) |
|---|---|---|---|
| 99202 | Straightforward | 15–29 min | ~$76 |
| 99203 | Low | 30–44 min | ~$110 |
| 99204 | Moderate | 45–59 min | ~$167 |
| 99205 | High | 60–74 min | ~$211 |
Established Patient E/M Codes
| CPT Code | MDM Complexity | Total Time | 2026 Medicare Rate (approx.) |
|---|---|---|---|
| 99212 | Straightforward | 10–19 min | ~$57 |
| 99213 | Low | 20–29 min | ~$93 |
| 99214 | Moderate | 30–39 min | ~$129 |
| 99215 | High | 40–54 min | ~$172 |
For psychiatric medication management, 99213 and 99214 are the most frequently billed codes. If you're managing a patient on multiple psychotropic medications with complex drug interactions or co-morbid medical conditions, 99214 or 99215 is often appropriate and defensible — but your note has to show the work.
5. Psychological and Neuropsychological Testing Codes
Psychologists and neuropsychologists use a separate family of codes for assessment services. These were significantly restructured in 2019, and many practices are still not billing them correctly.
| CPT Code | Description |
|---|---|
| 96130 | Psychological testing evaluation services, first hour (physician/QHP) |
| 96131 | Psychological testing, each additional hour |
| 96132 | Neuropsychological testing evaluation services, first hour |
| 96133 | Neuropsychological testing, each additional hour |
| 96136 | Psychological/neuropsychological test administration by physician/QHP, first 30 min |
| 96137 | Test administration by physician/QHP, each additional 30 min |
| 96138 | Test administration by technician, first 30 min |
| 96139 | Test administration by technician, each additional 30 min |
| 96146 | Psychological test admin via computer, automated |
The distinction between 96130/96132 (evaluation services) and 96136/96138 (test administration) is critical. Evaluation services cover the clinician's time for test selection, integration of data, report writing, and feedback. Administration codes cover the actual time spent administering the test instruments. These are billed separately and must be documented separately.
6. Health Behavior Assessment and Intervention Codes (96150–96161)
These codes are often overlooked but are increasingly important as behavioral health integrates with primary care and chronic disease management.
| CPT Code | Description |
|---|---|
| 96150 | Health behavior assessment, initial (15 min) |
| 96151 | Health behavior re-assessment (15 min) |
| 96152 | Health behavior intervention, individual (15 min) |
| 96153 | Health behavior intervention, group (15 min, per patient) |
| 96154 | Health behavior intervention, family with patient (15 min) |
| 96155 | Health behavior intervention, family without patient (15 min) |
| 96156 | Health behavior assessment/intervention, initial |
| 96158 | Health behavior intervention, individual, 30 min |
| 96159 | Health behavior intervention, each additional 15 min |
| 96160 | Patient-focused health risk assessment |
| 96161 | Caregiver-focused health risk assessment |
These codes are billed under the patient's medical diagnosis (e.g., diabetes, chronic pain, obesity), not a psychiatric diagnosis. This is a critical distinction — if you bill a psychiatric diagnosis alongside 96152, payers will likely deny it.
7. Telehealth Modifiers for Behavioral Health in 2026
Telehealth billing has stabilized significantly since the COVID-era emergency waivers. In 2026, here's what you need to know:
| Modifier | When to Use |
|---|---|
| 95 | Synchronous telehealth via audio-video (Medicare) |
| GT | Synchronous telehealth for Medicaid and some commercial payers |
| 93 | Audio-only telehealth (telephone) — where covered |
| FQ | Service furnished using audio-only communication technology (Medicare) |
Place of Service (POS) matters enormously. For Medicare:
- POS 02 — Telehealth provided in a location other than the patient's home
- POS 10 — Telehealth provided in the patient's home (most common for outpatient behavioral health)
Using POS 10 with modifier 95 is the standard for most outpatient teletherapy billed to Medicare in 2026. Using the wrong POS can result in a lower reimbursement rate or outright denial.
For commercial payers like Aetna and BCBS, check each payer's telehealth policy — some still require GT, and some have their own internal modifier requirements.
8. Group Therapy Codes
| CPT Code | Description | 2026 Medicare Rate (approx.) |
|---|---|---|
| 90853 | Group psychotherapy (not family) | ~$35–50 per patient |
| 90849 | Multiple-family group psychotherapy | ~$46 per patient |
Group therapy billing often trips up practices because each patient in the group gets their own claim line for 90853. You do not bill one claim for the group — you bill one unit of 90853 per patient per session. Documentation should note the group's therapeutic themes, each patient's participation, and the therapist's interventions.
9. Family Therapy Codes
| CPT Code | Description | 2026 Medicare Rate (approx.) |
|---|---|---|
| 90846 | Family psychotherapy without patient present | ~$108 |
| 90847 | Family psychotherapy with patient present | ~$115 |
A common error: billing 90847 when the identified patient did not attend. If only family members were present, the correct code is 90846.
10. Crisis Intervention Codes
| CPT Code | Description |
|---|---|
| 90839 | Psychotherapy for crisis, first 60 min |
| 90840 | Psychotherapy for crisis, each additional 30 min |
| 98966–98968 | Telephone assessment and management (non-physician) |
90839 has a specific clinical threshold. It requires documentation of an urgent or emergent situation, a disruption in the patient's normal activities, and a significant threat to the patient or others. Don't use it for a "really hard session" — use it when there's a genuine psychiatric emergency.
The Most Common CPT Coding Mistakes in Behavioral Health
- Upcoding 90837 without adequate time documentation. This is the #1 audit trigger for outpatient therapists.
- Billing 90792 for ongoing sessions. 90792 is an intake code, not a follow-up code.
- Missing the add-on code 90785 when complexity criteria are clearly met.
- Wrong Place of Service on telehealth claims.
- Not separating E/M and psychotherapy time when billing combo codes (90833/90836/90838 with an E/M).
- Billing 90837 for a 50-minute session. A standard 50-minute "therapy hour" maps to 90834, not 90837.
How AI-Powered Documentation Changes the Billing Equation
The single most common reason behavioral health claims get denied or audited is documentation that doesn't support the billed code. It's rarely intentional — it's usually a therapist who spent 60 minutes with a complex patient, billed 90837, and wrote a note that didn't clearly reflect the time or medical necessity.
This is exactly the problem that platforms like Mozu Health are built to solve.
FAQ: Behavioral Health CPT Codes 2026
Q1: What's the difference between 90834 and 90837? 90834 covers 38–52 minutes of face-to-face psychotherapy. 90837 covers 53 minutes or more. The most important word is "face-to-face" — prep time, note writing, and coordination of care do not count toward the time threshold for these codes.
Q2: Can a therapist (LPC, LCSW, LMFT) bill E/M codes? No. E/M codes (99202–99215) are restricted to physicians, nurse practitioners, physician assistants, and other licensed prescribers. Non-prescribing therapists bill using the psychotherapy family (90832–90837) and psychiatric evaluation codes (90791).
Q3: Can I bill 90837 for a standard 50-minute session? No. A standard 50-minute session falls within the 38–52 minute range, which maps to 90834. To bill 90837, your documented face-to-face psychotherapy time must be 53 minutes or more.
Q4: How do I bill for a session that was both medication management and therapy? If you're a prescriber, you bill the appropriate E/M code (e.g., 99214) plus the appropriate psychotherapy add-on code (90833, 90836, or 90838) based on the time spent in psychotherapy. The documentation must separately reflect the medical decision-making or time for the E/M component AND the psychotherapy time.
Q5: Is telehealth billed differently than in-person for behavioral health in 2026? The CPT codes themselves are the same — what changes is the Place of Service code and any required modifiers. For Medicare, use POS 10 + modifier 95 for most home-based teletherapy. For Medicaid and commercial, check each payer's specific policy, as requirements vary by state and contract.
Q6: What documentation is required to use 90785 (interactive complexity)? Your note must document one or more of the qualifying factors: presence of a third party (parent, guardian, interpreter), communication barriers, mandated reporting issues arising during the session, or coordination with multiple agencies due to a complex social situation. It's not enough to just note that the session was "complex."
Q7: Are there CPT code changes specific to behavioral health for 2026? The AMA releases its annual CPT updates each fall. For 2026, practices should watch for any revisions to the telehealth code set and any updates to the psychological testing codes. CMS's final Medicare Physician Fee Schedule rule, typically released in November for the following year, is your authoritative source for rate changes.
