CPT Code 90792: The Complete Guide to Psychiatric Evaluation With Medical Services
If you're a psychiatrist, PMHNP, or prescribing clinician billing for initial psychiatric evaluations, CPT code 90792 is one of the most important codes in your toolkit — and one of the most commonly underdocumented.
Whether you're new to behavioral health billing or you've been practicing for years and just want to make sure you're capturing every reimbursable dollar without triggering an audit, this guide covers everything you need to know about 90792: what it means, who can bill it, how much it pays, what payers want to see in the documentation, and how to avoid the most common costly mistakes.
Let's get into it.
What Is CPT Code 90792?
CPT code 90792 stands for Psychiatric Diagnostic Evaluation with Medical Services. It's the elevated counterpart to CPT code 90791 (Psychiatric Diagnostic Evaluation without medical services), and the distinction matters — both clinically and financially.
Here's the official AMA definition:
90792 — Psychiatric diagnostic evaluation with medical services (includes history, mental status exam, communication with family or other sources, ordering and medical interpretation of laboratory or other diagnostic studies, prescription of medications, and/or physical examination).
The key phrase is "with medical services." This code exists specifically for evaluations performed by a clinician licensed and qualified to provide medical services — typically a psychiatrist (MD/DO) or a psychiatric-mental health nurse practitioner (PMHNP) practicing under applicable state licensure. Therapists, LPCs, LCSWs, and LMFTs cannot bill 90792 — more on that below.
90792 vs. 90791: What's the Actual Difference?
This is one of the most frequently asked questions in behavioral health billing, and the confusion is understandable because both codes involve a psychiatric diagnostic evaluation. The difference comes down to scope of practice and what services are rendered during the encounter.
| Feature | CPT 90791 | CPT 90792 | |---|---|---| | Code Description | Psych Diagnostic Eval (no medical services) | Psych Diagnostic Eval (with medical services) | | Who Can Bill | Psychiatrists, therapists, LPCs, LCSWs, LMFTs, PMHNPs | Psychiatrists (MD/DO), PMHNPs (state-dependent) | | Medical Decision-Making | Not required | Required | | Medication Management | Not included | Can be included | | Rx Authority Required | No | Yes | | Physical Exam | Not required | May be included | | Lab Orders/Interpretation | Not included | Can be included | | 2026 National Medicare Rate | ~$162–$170 | ~$185–$205 | | Typical Commercial Rate | $200–$350 | $250–$450+ |
The simplest way to think about it: if the evaluation includes a prescribing decision, medication order, lab interpretation, or physical exam — and the clinician is licensed to perform those services — you're billing 90792, not 90791.
Choosing the wrong code is a compliance risk. Billing 90792 when you only provided a diagnostic interview (without medical services) is upcoding. Billing 90791 when you did perform medical services is undercoding — and you're leaving real money on the table.
Who Can Bill CPT 90792?
This is where scope-of-practice rules intersect with billing rules, and it's critical to get right.
Qualified providers for 90792:
- Psychiatrists (MD/DO) — universally recognized by all payers
- PMHNPs (Psychiatric-Mental Health Nurse Practitioners) — recognized by most major payers when practicing within state licensure and prescriptive authority
- Physician Assistants with psychiatric specialization — some payers recognize this; verify individually
Who cannot bill 90792:
- Licensed Professional Counselors (LPCs)
- Licensed Clinical Social Workers (LCSWs)
- Licensed Marriage and Family Therapists (LMFTs)
- Psychologists (in most states, unless they hold prescriptive authority — currently limited to NM, LA, IL, IA, ID, CO)
- Licensed Mental Health Counselors (LMHCs)
If you're a non-prescribing clinician performing a comprehensive intake, your code is 90791, period. Attempting to bill 90792 without prescriptive authority or the delivery of actual medical services is a significant compliance violation that can result in claim denial, recoupment, or exclusion from payer networks.
2026 Medicare Reimbursement Rates for 90792
Medicare reimbursement for CPT 90792 is calculated using the Medicare Physician Fee Schedule (MPFS) and varies slightly by geographic location (Medicare locality).
For 2026, the national non-facility rate for CPT 90792 is approximately $201–$215 depending on your locality. The facility rate (for services rendered in a hospital or clinic setting) is lower, typically $130–$150.
Here are approximate 2026 Medicare rates for major markets:
| Geographic Area | Non-Facility Rate | Facility Rate | |---|---|---| | National Average | ~$208 | ~$141 | | New York (Metro) | ~$235 | ~$158 | | Los Angeles, CA | ~$228 | ~$153 | | Chicago, IL | ~$215 | ~$144 | | Dallas, TX | ~$202 | ~$138 | | Miami, FL | ~$218 | ~$147 | | Rural/Low-Cost Areas | ~$185 | ~$128 |
Note: Always verify current rates at CMS.gov or through your clearinghouse, as MPFS rates are updated annually.
Commercial payers — Aetna, Cigna, UnitedHealthcare, BlueCross BlueShield, Humana — typically reimburse at 120–200% of Medicare rates for 90792, depending on your contract. Out-of-network or private pay rates vary widely and can range from $350 to $600+ for initial psychiatric evaluations in major metros.
Documentation Requirements for 90792
Here's where most claim denials and audit failures actually happen — not in the code selection, but in the documentation. Payers (and CMS for Medicare/Medicaid) want to see specific elements in your note to justify billing 90792.
Required Documentation Elements
1. Chief Complaint Document the patient's primary reason for seeking evaluation in their own words when possible.
2. History of Present Illness (HPI) This needs to be thorough — onset, duration, severity, modifying factors, associated symptoms, and prior psychiatric history.
3. Psychiatric and Medical History Include past psychiatric diagnoses, prior hospitalizations, current medications (prescribed and OTC), allergies, and relevant medical conditions.
4. Social and Developmental History Family psychiatric history, substance use history, social determinants of health, and relevant developmental history.
5. Mental Status Examination (MSE) This is non-negotiable. Your MSE should document: appearance, behavior, speech, mood, affect, thought process, thought content, perceptual disturbances, cognitive function, insight, and judgment.
6. Medical Component — THIS IS THE DIFFERENTIATING FACTOR To justify 90792 over 90791, your note must clearly document the medical services rendered. This includes one or more of the following:
- A prescribing decision (starting, adjusting, or discontinuing medication — including rationale)
- Lab orders or interpretations (e.g., metabolic panel, thyroid function, serum lithium level)
- A physical examination (even a targeted one)
- Review and interpretation of prior medical records with clinical integration
- Medical decision-making that affects the psychiatric treatment plan
7. Diagnostic Impression List diagnoses using current DSM-5-TR criteria and corresponding ICD-10-CM codes.
8. Treatment Plan Document the plan comprehensively: medications with doses/frequencies, therapy referrals, follow-up schedule, safety planning if applicable, and patient education provided.
9. Time (optional but increasingly useful) While 90792 is not time-based like psychotherapy add-ons, documenting time spent can support medical necessity arguments during audits.
A Note on "Medical Services" Documentation
The single most common reason 90792 claims are downcoded to 90791 upon audit is that the note fails to clearly document what medical service was actually rendered. You can't just check a box or include a generic line like "medications discussed." You need to document which medications, why those medications, what the clinical rationale was, and what the patient was told.
Can You Bill 90792 With Other Codes?
Yes — and knowing these combinations can significantly increase appropriate reimbursement.
90792 + Psychotherapy Add-Ons
You cannot bill 90792 with the psychotherapy add-on codes (90833, 90836, 90838) on the same day. These add-ons are only applicable to E/M codes. This is a common billing error.
90792 + E/M Codes
You cannot bill 90792 with an Evaluation and Management (E/M) code (99202–99215) on the same day by the same provider. The services are considered bundled.
90792 + Collaborative Care (CoCM)
If you're functioning as a psychiatric consultant in a Collaborative Care Model (CoCM), you can bill 90792 for the initial face-to-face evaluation as part of the CoCM bundle. Understand how this interacts with 99492/99493/99494 billing.
90792 + Telehealth
Great news: 90792 is fully approved for telehealth delivery under both Medicare and most commercial payers as of 2026. Append modifier GT (for Medicare Advantage and some commercial plans) or use POS 10 (telehealth provided in patient's home) or POS 02 (telehealth provided other than in patient's home) as required by payer. Since the PHE telehealth expansions were largely made permanent, telehealth psychiatric evaluations have become a standard billing scenario.
Common Billing Errors and How to Avoid Them
After reviewing thousands of behavioral health claims, here are the mistakes we see most often with 90792:
1. Billing 90792 when no medical services were rendered If you performed a diagnostic interview only and didn't prescribe, order labs, or render any medical service — bill 90791.
2. Using 90792 for non-prescribing clinicians Therapists and counselors billing 90792 are at serious risk of fraud allegations. The code requires medical service delivery.
3. Vague documentation of the medical component "Medication options were reviewed" is not sufficient. Document specifically: the medication considered, the dose, the rationale, any alternatives discussed, and the patient's response.
4. Billing 90792 for every follow-up appointment 90792 is for initial or re-evaluation diagnostic encounters — not routine medication management visits. Routine follow-ups should be billed using E/M codes (99212–99215) with appropriate add-on psychotherapy codes when applicable.
5. Missing ICD-10 codes or using unspecified codes Pair your 90792 claim with the most specific ICD-10-CM diagnosis code available. Relying on F41.9 (anxiety disorder, unspecified) or F32.9 (major depressive disorder, unspecified) when you have enough clinical information for a more specific code can trigger audit flags.
6. Ignoring payer-specific rules Aetna, UnitedHealthcare, and Cigna all have individual behavioral health billing guidelines. Some require prior authorization for 90792 from certain provider types. Always verify.
Payer-Specific Considerations for 90792
While 90792 is a standard CPT code recognized by all major payers, policies on authorization, frequency, and qualifying provider types vary:
- Medicare/Medicaid: No prior auth required for 90792 in most cases. PMHNP billing is recognized. Incident-to billing does not apply to psychiatric diagnostic evaluations.
- UnitedHealthcare: Recognizes 90792 for psychiatrists and PMHNPs. May require auth for certain specialty designations.
- Aetna: Generally covers 90792 without PA for in-network psychiatrists. Prior auth requirements may apply for out-of-network or certain facilities.
- Cigna/Evernorth: Behavioral health carve-out — verify credentialing and authorization through Evernorth separately.
- BlueCross BlueShield: Varies significantly by state plan. Some BCBS plans require separate behavioral health credentialing.
- Medicaid (state-specific): Many state Medicaid programs have additional documentation requirements and lower reimbursement rates. Confirm with your state's provider manual.
Audit Risk and Compliance Tips for 90792
CPT 90792 is a higher-value code and therefore subject to more scrutiny than lower-value codes. CMS RAC (Recovery Audit Contractor) audits and commercial payer post-payment audits frequently target psychiatric evaluation codes.
To protect yourself:
- Document the medical services explicitly — every time, without exception
- Use structured templates that prompt you to capture all required elements
- Avoid copy-paste documentation — it's a top audit red flag
- Conduct internal audits quarterly — review a sample of your 90792 claims against documentation
- Store documentation in a HIPAA-compliant system with audit logs
- Know your error rate — if more than 5% of your 90792 claims result in denials or downcodes, something is wrong with your documentation process
Frequently Asked Questions About CPT Code 90792
1. How many times can I bill CPT 90792 for the same patient?
Most payers allow 90792 to be billed once per patient episode of care for the initial evaluation. It can be billed again if the patient returns after a significant gap in treatment (typically 1–3 years, depending on payer policy) or following a new clinical episode requiring a fresh diagnostic workup. Routine medication management visits should be billed as E/M codes, not 90792.
2. Can a therapist bill 90792 if they're working under a psychiatrist's supervision?
No. CPT 90792 requires the rendering provider to have the authority and licensure to perform medical services. Incident-to billing rules do not apply to psychiatric diagnostic evaluation codes under Medicare, and most commercial payers follow suit. The service must be personally performed by a qualified provider.
3. What's the difference between 90792 and 99205 for a new patient psychiatric evaluation?
This is a nuanced question. 90792 is a psychiatric-specific diagnostic code designed for comprehensive psychiatric evaluations that include medical services. 99205 is the highest-level E/M code for new patients and is used more commonly in primary care or when the visit is primarily medical in nature. Some psychiatrists use 99205 + psychotherapy add-on codes (90833) for their new patient visits, while others prefer 90792 — the right choice depends on the nature of the visit and your documentation. You cannot bill both on the same day.
4. Can I bill 90792 via telehealth?
Yes. As of 2026, 90792 is on Medicare's approved telehealth services list and is reimbursed at the same rate as in-person visits for most payers. Use the appropriate place of service code (POS 10 or POS 02) and any required modifiers per your payer contracts.
5. What ICD-10 codes should I pair with 90792?
Use the most clinically accurate and specific ICD-10-CM code based on your diagnostic impression. Common pairings include:
- F32.1 – Major depressive disorder, single episode, moderate
- F41.1 – Generalized anxiety disorder
- F31.81 – Bipolar II disorder
- F20.9 – Schizophrenia
- F90.2 – ADHD, combined presentation
- F43.10 – PTSD, unspecified
Avoid over-relying on "unspecified" codes (e.g., F41.9, F32.9) when a more specific code is clinically supported.
6. Does 90792 require a separate consent form?
While there is no universal federal mandate for a 90792-specific consent form, most state licensing boards and payer contracts require documented informed consent for psychiatric evaluation and treatment, including medication consent where applicable. This should be part of your standard intake process and documented in the patient's record.
7. Can group practices bill 90792 under a group NPI?
Yes, group practices can bill 90792 under the group NPI, but the rendering provider NPI must be included on the claim (Box 24J on the CMS-1500 form) and must be credentialed with the payer as a qualified provider for this service.
The Bottom Line on CPT Code 90792
CPT code 90792 is a high-value, clinically important code that enables prescribing clinicians to be appropriately reimbursed for the full scope of psychiatric evaluation services they deliver. But it comes with real documentation responsibility.
Get the documentation right — explicitly capture the medical services rendered, build a thorough MSE, include a clinically sound treatment plan with prescribing rationale — and 90792 is a straightforward, defensible claim. Cut corners, use vague language, or let your templates auto-populate without clinical substance, and you're building audit risk with every note you sign.
The difference between a clean 90792 claim and a denial or recoupment notice almost always lives in the quality of your clinical note.
