Superbill CPT Codes for Mental Health: The Complete 2026 Guide for Therapists, LPCs, LCSWs, LMFTs & Psychiatrists
If you've ever spent 20 minutes Googling "what CPT code do I use for a 45-minute therapy session" or had a claim denied because you billed 90837 when you meant 90834, this guide is for you.
A superbill is one of the most powerful billing tools in your practice — but only if it's built correctly. Use the wrong CPT code, miss a modifier, or forget a diagnosis code, and you're leaving real money on the table (or worse, triggering a payer audit).
This is the definitive, practitioner-facing breakdown of every CPT code that should be on your mental health superbill in 2026, including psychotherapy codes, psychiatric codes, assessment codes, crisis codes, and the add-on codes most clinicians forget to bill.
Let's get into it.
What Is a Mental Health Superbill (and Why Does It Matter)?
A superbill is a detailed receipt that contains all the information a patient — or their insurance company — needs to process a reimbursement claim. For out-of-network providers, it's what clients submit to their insurer for reimbursement. For in-network providers, it's the billing foundation behind every ERA (Electronic Remittance Advice) you receive.
A well-built mental health superbill includes:
- Provider NPI and tax ID
- Practice name, address, and phone number
- Client name and date of birth
- Date of service
- Place of service code (POS 02 for telehealth, POS 11 for office)
- CPT code(s) with description and time
- ICD-10 diagnosis code(s)
- Fee charged and amount paid
- Provider signature and credentials
Missing any of these? Your client's claim gets rejected, they come back frustrated, and your reputation takes a hit — even though the clinical work was excellent.
The Complete List of Mental Health CPT Codes for Your Superbill
🧠 Psychotherapy CPT Codes (Individual)
These are the workhorses of any therapy practice superbill. The time thresholds are strict — you need to hit the midpoint of the stated range to bill that code.
| CPT Code | Description | Typical Session Time | 2025 Medicare Rate (National) |
|---|---|---|---|
| 90832 | Psychotherapy, 30 minutes | 16–37 minutes | ~$68 |
| 90834 | Psychotherapy, 45 minutes | 38–52 minutes | ~$99 |
| 90837 | Psychotherapy, 60 minutes | 53+ minutes | ~$136 |
| 90839 | Psychotherapy for crisis, first 60 min | First 60 min of crisis | ~$174 |
| 90840 | Psychotherapy for crisis, each add'l 30 min | Add-on to 90839 | ~$82 |
Pro tip: 90837 is the most commonly billed individual therapy code — and the most commonly audited. If you're billing it, make sure your note documents why 60 minutes was medically necessary, not just that the session ran long because you were chatting.
👥 Psychotherapy Add-On Codes (With E&M)
These add-on codes are used when a prescriber or other licensed clinician provides both an Evaluation & Management (E&M) service and psychotherapy during the same visit. You cannot bill these standalone — they must be paired with an E&M code.
| CPT Code | Description | Time | 2025 Medicare Rate |
|---|---|---|---|
| 90833 | Psychotherapy add-on, 30 min | 16–37 min of psychotherapy | ~$68 |
| 90836 | Psychotherapy add-on, 45 min | 38–52 min of psychotherapy | ~$99 |
| 90838 | Psychotherapy add-on, 60 min | 53+ min of psychotherapy | ~$136 |
These are commonly used by psychiatrists, psychiatric NPs, and integrated care providers who conduct medication management and therapy in the same encounter. Most solo therapists won't use these — but if you're in a collaborative care model, know them cold.
👨👩👧 Group, Family, and Couples Therapy CPT Codes
| CPT Code | Description | Notes |
|---|---|---|
| 90847 | Family/couples therapy WITH client present | Most commonly billed for couples therapy |
| 90846 | Family therapy WITHOUT client present | Collateral sessions, parent coaching |
| 90853 | Group psychotherapy | Requires 2+ unrelated clients; not couples |
| 90849 | Multiple-family group psychotherapy | Less common; used in structured programs |
Common mistake: Billing 90847 for a couples session where the identified client wasn't present. If one partner doesn't show, you're technically in 90846 territory — and insurers will catch this in audits.
🩺 Psychiatric Evaluation & Management (E&M) CPT Codes
These are the codes psychiatrists and psychiatric NPs live in. The 2021 E&M changes dramatically shifted how these codes are selected — it's now based on medical decision-making (MDM) or total time, not the number of elements documented.
| CPT Code | Description | MDM Level | Typical Total Time |
|---|---|---|---|
| 99202 | New patient, office visit | Straightforward | ~15–29 min |
| 99203 | New patient, office visit | Low complexity | ~30–44 min |
| 99204 | New patient, office visit | Moderate complexity | ~45–59 min |
| 99205 | New patient, office visit | High complexity | ~60–74 min |
| 99211 | Established patient, minimal | Minimal/None | ~10 min |
| 99212 | Established patient, office visit | Straightforward | ~10–19 min |
| 99213 | Established patient, office visit | Low complexity | ~20–29 min |
| 99214 | Established patient, office visit | Moderate complexity | ~30–39 min |
| 99215 | Established patient, office visit | High complexity | ~40–54 min |
99214 is the most common psychiatric medication management code — most 20–30 minute med checks with prescription renewals, symptom review, and one or more chronic conditions land here under moderate MDM.
📋 Psychiatric Diagnostic Evaluation Codes
| CPT Code | Description | Notes |
|---|---|---|
| 90791 | Psychiatric diagnostic evaluation | No medical services (therapists use this) |
| 90792 | Psychiatric diagnostic eval with medical services | Prescribers only (MD, DO, NP, PA) |
These are your intake/initial evaluation codes. 90791 is used for the first session when you're establishing the clinical picture and formulating a diagnosis. Don't bill it repeatedly for the same client — most payers allow it once per treatment episode (some allow once per 365 days).
🧪 Psychological & Neuropsychological Testing CPT Codes
| CPT Code | Description | Who Bills |
|---|---|---|
| 96130 | Psychological testing evaluation, first hour | Psychologist/physician |
| 96131 | Psychological testing, each additional hour | Add-on to 96130 |
| 96132 | Neuropsychological testing evaluation, first hour | Psychologist/physician |
| 96133 | Neuropsychological testing, each additional hour | Add-on to 96132 |
| 96136 | Psychological testing administration, first 30 min | Tech or clinician |
| 96137 | Psychological testing administration, each add'l 30 min | Add-on to 96136 |
| 96138 | Neuropsychological testing administration, first 30 min | Tech or clinician |
| 96139 | Neuropsychological testing administration, each add'l 30 min | Add-on to 96138 |
| 96146 | Psychological testing using standardized instrument, automated | Automated/self-administered |
📞 Telehealth, Phone & Digital CPT Codes
Telehealth billing has never been more relevant — or more payer-specific. Here's what you need to know:
| CPT Code | Description | Notes |
|---|---|---|
| All above codes | Delivered via telehealth | Append modifier 95 (synchronous) or GT (for Medicare/Medicaid) |
| 98966 | Telephone assessment, 5–10 min | Non-physician, established patient |
| 98967 | Telephone assessment, 11–20 min | Non-physician, established patient |
| 98968 | Telephone assessment, 21–30 min | Non-physician, established patient |
| 99421 | Online digital E&M, 5–10 min | Patient-initiated, within 7 days |
| 99422 | Online digital E&M, 11–20 min | Patient-initiated, within 7 days |
| 99423 | Online digital E&M, 21+ min | Patient-initiated, within 7 days |
Important: Place of Service code 02 is used for telehealth when the patient is at a location other than their home. Use POS 10 when the patient is at home (which became permanently reimbursable for many payers post-pandemic). The distinction matters — Medicare pays differently based on POS.
🆘 Crisis Intervention CPT Codes
| CPT Code | Description | Notes |
|---|---|---|
| 90839 | Psychotherapy for crisis, first 60 min | Can be billed by any licensed clinician |
| 90840 | Each additional 30 min of crisis therapy | Add-on to 90839 only |
| 98968 | Telephone crisis assessment, 21–30 min | For phone-based crisis triage |
Crisis codes require specific documentation: that the patient presented with a psychiatric emergency or urgent situation requiring immediate clinical intervention, and that the clinician spent the documented time providing crisis-focused psychotherapy. These are not billable for routine sessions that happened to go long.
🧩 Collaborative Care & Care Management Codes
If you work in an integrated care setting or run a collaborative care model (CoCM), these codes can significantly increase your practice revenue:
| CPT Code | Description | Monthly Time |
|---|---|---|
| 99492 | Initial psychiatric CoCM, first 70 min | First calendar month |
| 99493 | Subsequent CoCM, first 60 min | Each subsequent month |
| 99494 | CoCM, each additional 30 min | Add-on to 99492 or 99493 |
These are billed by the billing provider/supervising physician — not the BHC (behavioral health care manager) individually. They require a registry, care team coordination, and a supervising psychiatrist. But for qualifying practices, they can add $100–$200 per enrolled patient per month in additional revenue.
Modifier Codes You Must Know
Modifiers change how a CPT code is interpreted by a payer. Using the wrong one — or forgetting one — is one of the top reasons mental health claims are denied or reduced.
| Modifier | When to Use |
|---|---|
| GT | Medicare/Medicaid telehealth (synchronous audio-video) |
| 95 | Commercial payer telehealth (synchronous) |
| FQ | Audio-only telehealth (Medicare, when video not available) |
| 93 | Audio-only telehealth (commercial payers) |
| 52 | Reduced services (session significantly shorter than typical) |
| 59 | Distinct procedural service (when billing two separate services same day) |
| HO | Master's level clinician |
| HN | Bachelor's level clinician |
| U1–U9 | State Medicaid program-specific modifiers (varies by state) |
ICD-10 Codes That Pair with Your Superbill CPTs
Your CPT code tells the insurer what you did. Your ICD-10 code tells them why it was medically necessary. Mismatches cause denials. Here are the most commonly used mental health diagnosis codes:
| ICD-10 Code | Diagnosis |
|---|---|
| F32.1 | Major depressive disorder, moderate |
| F33.1 | Recurrent MDD, moderate |
| F41.1 | Generalized anxiety disorder |
| F41.0 | Panic disorder |
| F43.10 | PTSD, unspecified |
| F43.12 | PTSD, chronic |
| F90.0 | ADHD, predominantly inattentive |
| F31.9 | Bipolar disorder, unspecified |
| F20.9 | Schizophrenia, unspecified |
| F50.00 | Anorexia nervosa, unspecified |
| F60.3 | Borderline personality disorder |
| Z03.89 | Encounter for observation, no diagnosis confirmed |
Documentation tip: You can list up to 12 diagnosis codes on a CMS-1500 claim form. For complex clients, list the primary diagnosis first and supporting diagnoses in order of clinical relevance — don't just list one diagnosis across 100 sessions if the clinical picture is more complex.
Superbill Best Practices: What Auditors Look For
Payers like Aetna, UnitedHealthcare, Cigna, and BlueCross routinely audit mental health claims. Here's what triggers scrutiny:
- Billing 90837 for every single session — without documented medical necessity for 60-minute services
- 90791 billed more than once per treatment episode for the same client
- Session length not matching billed code — your note says 45 minutes but you billed 90837
- Modifier 95 missing on telehealth claims — results in claim being treated as in-person
- Diagnosis codes that don't support medical necessity — billing F41.9 (anxiety, unspecified) for every client raises flags
- Group therapy billed as individual — 90853 vs. 90837 requires documentation of group composition
The clinical documentation behind your superbill is your legal and financial protection. If your notes don't support your codes, you're exposed.

Frequently Asked Questions
1. What CPT code do I use for a standard 50-minute therapy session?
A standard "50-minute hour" in therapy actually falls under 90837 (psychotherapy, 60 minutes), which covers sessions of 53 minutes or longer. If your session is consistently 45–52 minutes, you should be billing 90834. The key is that the documented session time must match the billed code — so make sure your notes reflect the actual time spent.
2. Can I bill both 90837 and 90833 on the same day?
Not exactly. 90833 is an add-on code for psychotherapy provided in addition to an E&M service. A therapist billing 90837 (standalone therapy) cannot also bill 90833. However, a psychiatrist who provides both medication management (e.g., 99214) and psychotherapy in the same visit can bill 99214 + 90833 together. These codes are designed for different clinical roles.
3. How often can I bill 90791 for the same client?
Most payers allow 90791 once per treatment episode or once every 365 days. Some Medicaid plans allow it at the start of each new authorization period. Billing it repeatedly without a clear clinical justification (like a new presenting problem after a long gap in treatment) is a common audit trigger. Always check your payer-specific policies.
4. What's the difference between 90846 and 90847?
90847 is family therapy with the identified patient present. 90846 is family therapy without the patient — used for sessions with parents, caregivers, or collateral contacts where the client isn't in the room. Some payers won't reimburse 90846 at all, or will require prior authorization for it. Check your contracted payer policies before billing it regularly.
5. Do I need a modifier for telehealth therapy sessions?
Yes — and the modifier depends on the payer. For Medicare, use modifier GT (or FQ for audio-only). For most commercial payers (Aetna, Cigna, UHC, BCBS), use modifier 95 for synchronous video sessions and 93 for audio-only. You also need to use the correct Place of Service code: POS 02 for telehealth at a facility, POS 10 for telehealth at the patient's home. Missing modifiers or POS codes are a leading cause of telehealth claim denials.
6. Can LCSWs and LPCs bill psychiatric evaluation codes like 90792?
No. 90792 includes medical services and is restricted to providers with prescribing authority — physicians, NPs, and PAs. LCSWs, LPCs, and LMFTs should use 90791 for their initial diagnostic evaluations. The distinction matters both for billing and for scope of practice compliance.
7. What happens if I bill the wrong CPT code on a superbill?
If you bill the wrong code, you risk a claim denial, a request for medical records, a repayment demand (if you were overpaid), or in egregious cases, an accusation of fraud or upcoding. If you discover a billing error, the correct course is to submit a corrected claim (with claim frequency code 7 on a CMS-1500) promptly. Proactive correction is always better than waiting for an audit.
Final Thoughts
Billing mental health services accurately isn't just about getting paid — it's about protecting your license, your practice, and your clients' access to continued care. A superbill with the right CPT codes, correct modifiers, and matching diagnosis codes is a clinical document as much as it is a financial one.
The codes in this guide are the foundation. The documentation behind them is the structure. And the right tools make the whole thing sustainable.
