01. Introduction: Why Getting This Code Right Matters in 2026
Few billing decisions in behavioral health carry more consequence than the choice between CPT 90791 and CPT 90792. On the surface, these two codes describe the same service a psychiatric diagnostic evaluation. But the single phrase that separates them, "with medical services," determines which providers can bill the code, what documentation is required, and what reimbursement the practice receives.
Psychiatrists submitting 90791 when the encounter included medication evaluation are leaving significant reimbursement on the table. Non-prescribers billing 90792 are submitting claims they aren't eligible to submit and creating overpayment recoupment risk in the process. And providers across both categories who document an evaluation without addressing the specific elements each code requires are inviting denials that compound into AR backlogs over weeks and months.
This guide cuts through the confusion. Every explanation is grounded in current CMS coding guidelines and 2026 payer practices. Every recommendation is practical and actionable. Whether you're a psychiatrist building out a new practice, a billing manager onboarding a psychiatric provider, or a therapist clarifying what you can and cannot bill you'll find clear, accurate guidance here.
90791 Psychiatric Eval — No Medical Services | ~$168 Approx. 2026 Medicare Rate, Non-Facility | 90792 Psychiatric Eval — With Medical Services | ~$228 Approx. 2026 Medicare Rate, Non-Facility |
02. Quick Answer: CPT 90791 vs. 90792 at a Glance
⚡ FEATURED SNIPPET — What Is the Difference Between CPT 90791 and CPT 90792? CPT 90791 (Psychiatric Diagnostic Evaluation) is used when a clinician conducts a comprehensive mental health assessment that does NOT include medical services such as medication management or medical decision making. It can be billed by a broad range of licensed mental health providers, including psychiatrists, psychologists, licensed clinical social workers, licensed professional counselors, and licensed marriage and family therapists — provided they are credentialed with the payer. CPT 90792 (Psychiatric Diagnostic Evaluation WITH Medical Services) is used when the evaluation also includes a medical services component — typically medication evaluation, medication management, physical examination findings, or complex medical decision making related to psychiatric care. It is restricted to providers with prescriptive authority: psychiatrists, psychiatric nurse practitioners, psychiatric physician assistants, and physicians. The bottom line: Use 90791 for a psychiatric evaluation without medication involvement. Use 90792 when medication assessment or other medical services are part of the same encounter — and only if you are a prescriber. |
03. CPT 90791 — Psychiatric Diagnostic Evaluation
CPT 90791 covers a comprehensive psychiatric diagnostic evaluation conducted without any medical services component. It is used to assess a patient's psychiatric, psychological, social, and developmental history, establish a diagnosis, and develop a treatment plan. Unlike the psychotherapy codes (90832/90834/90837), CPT 90791 is not time-based it describes a clinical service type, not a duration.
This is typically a one-time evaluation code used at the beginning of a course of psychiatric treatment. Some payers permit it to be billed annually for existing patients receiving a comprehensive reassessment, but billing it repeatedly as an ongoing session code is incorrect and represents one of the most common errors in psychiatric billing.
ℹ️ CPT 90791 Quick Facts Full Name: Psychiatric Diagnostic Evaluation Medical Services Included: No Time-Based: No — service type code (not duration-based like 90832/90834/90837) Global Period: 0 days (evaluation code — not a surgical procedure) Eligible Providers: Psychiatrists, psychologists, LCSWs, LPCs, LMFTs, psychiatric NPs (when credentialed) 2026 Medicare Rate (approx.): ~$168 non-facility | ~$152 facility setting |
CPT 90791 Documentation Requirements & Billing Impact
04. CPT 90792 — Psychiatric Diagnostic Evaluation with Medical Services
CPT 90792 is the evaluation code used when a psychiatric provider conducts the same comprehensive evaluation as 90791 AND also delivers medical services as part of the same encounter. Medical services include medication evaluation, medication management, prescribing decisions, physical examination findings relevant to psychiatric care, or other medically-oriented clinical decision making.
Because it includes a medical services component, CPT 90792 is restricted to providers with prescriptive authority and medical evaluation privileges: psychiatrists, psychiatric nurse practitioners, psychiatric physician assistants, and other physicians practicing in psychiatric settings. Non-prescribers including LCSWs, LPCs, LMFTs, and psychologists without prescriptive authority — are not eligible to bill 90792 regardless of the complexity of their evaluation.
ℹ️ CPT 90792 Quick Facts Full Name: Psychiatric Diagnostic Evaluation with Medical Services Medical Services Included: Yes — medication evaluation, medical decision making, or physical exam component required Time-Based: No — service type code, not duration-based Global Period: 0 days Eligible Providers: Psychiatrists, psychiatric NPs, psychiatric PAs, physicians with psychiatric scope NOT Eligible: LCSWs, LPCs, LMFTs, psychologists (unless licensed to prescribe in their state) 2026 Medicare Rate (approx.): ~$228 non-facility | ~$204 facility setting |
CPT 90792 Documentation Requirements & Billing Impact
05. CPT 90791 vs. 90792 — Full Side-by-Side Comparison
This table captures every clinically and operationally significant difference between CPT 90791 and CPT 90792. Use this as your quick reference guide before submitting psychiatric evaluation claims.
💡 Key Revenue Insight: 90792 vs. 90791 For psychiatrists and psychiatric nurse practitioners who routinely include medication evaluation in initial assessments, correctly billing 90792 instead of 90791 represents approximately $60 more per evaluation at Medicare rates — and often significantly more with commercial payers. For a practice conducting 100 initial psychiatric evaluations per year, this single coding distinction is worth $6,000 or more annually at Medicare rates alone. The documentation requirements are only slightly more detailed, and the clinical work is already being performed. The revenue difference is recoverable with proper documentation. |
06. Documentation Requirements Checklists for Both Codes
The documentation required for psychiatric evaluation codes is more comprehensive than most providers realize. Payers are increasingly using automated systems to pre-screen psychiatric evaluation claims for documentation completeness before a human reviewer ever sees them. Missing a single required element can trigger automatic denial on first submission.
CPT 90791 — Complete Documentation Checklist
✓ Chief complaint documented — specific reason for psychiatric evaluation
✓ History of present psychiatric illness with symptom onset, duration, and severity
✓ Past psychiatric history — prior diagnoses, hospitalizations, previous treatments
✓ Medical history relevant to psychiatric presentation
✓ Family psychiatric history
✓ Social and developmental history — education, occupation, relationships, substance use
✓ Mental Status Examination — orientation, appearance, behavior, mood, affect, speech, thought process, thought content, perceptual disturbances, cognition, insight, and judgment
✓ DSM-5 diagnosis with specific ICD-10-CM code — avoid unspecified codes when specific code is supported
✓ Risk assessment documented — suicidality, self-harm, homicidality (document even when risk is low)
✓ Medical necessity justification — why psychiatric evaluation was clinically indicated
✓ Treatment plan with specific recommendations: therapy, referrals, follow-up frequency, or other next steps
✓ Provider signature with full name and professional licensure credentials
✓ Date of service, location of service, and patient identifying information
CPT 90792 — Additional Documentation Requirements (Beyond 90791)
✓ All elements from the CPT 90791 checklist above — the full psychiatric evaluation must be documented
✓ Comprehensive medical history — current medical conditions affecting psychiatric diagnosis or treatment
✓ Complete medication reconciliation — all current medications, dosages, prescribing providers, and psychiatric relevance
✓ Review of systems — neurological, cardiovascular, endocrine, and other relevant systems documented
✓ Medical decision making documentation — complexity of decisions regarding medication, medical risk, and treatment options
✓ Medication plan or prescribing intent — what medications are being started, continued, adjusted, or discussed; risks reviewed with patient
✓ Patient consent to medication treatment documented when applicable
✓ Physical examination findings when medically relevant to the psychiatric evaluation
✓ Monitoring plan for medications or medical conditions addressed in the evaluation
✓ Provider credentials clearly establishing prescriptive authority or medical evaluation privileges
⚠️ Documentation Red Flag: Template Notes Without Individualized Content The most common audit finding in psychiatric evaluation claims is the use of templated, copy-paste clinical notes that lack individualized patient content. A mental status examination that reads identically across multiple patients is a flag for clinical reviewers. Each 90791 and 90792 note must reflect what was actually observed and assessed in that specific evaluation — not what the template defaults to. Individualized language in the MSE, specific symptom descriptions, and patient-specific treatment planning are what distinguish defensible notes from audit-vulnerable ones. |
07. Common Billing Errors & How to Prevent Every One
Psychiatric evaluation billing errors fall into two categories: provider eligibility errors (billing a code you aren't qualified to submit) and documentation errors (billing a code your notes don't support). Both carry financial and compliance consequences. Here are the most common ones in 2026:
Billing Error | Why It Happens | Prevention Strategy |
Non-prescriber billing CPT 90792 | LCSW, LPC, or therapist selects 90792 without realizing prescriptive authority is required | Build provider-type verification into your billing workflow; 90792 is locked to prescribers only |
Psychiatrist billing 90791 when 90792 applies | Failing to recognize that the encounter included medication evaluation | Review the documentation: if medications were discussed or evaluated, 90792 is the correct code |
Using unspecified ICD-10 codes | F32.9 or F41.9 used as defaults when specific DSM-5 diagnosis was established | Review DSM-5 criteria; use F33.0, F41.1, F43.10, F20.9, etc. when the documentation supports specificity |
Billing 90791 or 90792 for established-patient therapy sessions | Confusing initial evaluation codes with ongoing psychotherapy codes | 90791/90792 are evaluation codes; use 90832/90834/90837 for ongoing therapy — do not reuse evaluation codes for repeat sessions |
Billing both 90791 and 90792 for the same patient on the same date | Clerical or software error; misunderstanding that codes are mutually exclusive | These codes are mutually exclusive — only one can be billed per encounter; payers will deny both when both appear |
Missing medical services documentation for 90792 | Psychiatrist bills 90792 but note only reflects a standard psychiatric evaluation | Explicitly document medication review, MDM, and prescribing plan — without it, 90792 downcodes to 90791 |
Prior authorization not obtained | PA requirement for psychiatric evaluations not verified before the appointment | Check prior auth requirements for both 90791 and 90792 with each payer before scheduling evaluations |
Duplicate claim submission | Claim corrected or resubmitted without proper adjustment code | Use the void-and-replace process; never resubmit original claim without corrective action |
✅ How to Avoid These Mistakes — A Practical Checklist Before submitting any 90791 or 90792 claim: ✓ Verify the billing provider type is eligible for the selected code (90792 = prescribers only) ✓ Confirm the clinical note documents all required elements for the selected code ✓ Verify the ICD-10 code is as specific as the documentation supports — never default to F32.9 or F41.9 when a specific code applies ✓ Confirm this is an initial evaluation encounter, not a repeat therapy session ✓ Verify only one psychiatric evaluation code is submitted for this date of service ✓ Confirm prior authorization was obtained if required by the payer ✓ Review medication documentation if billing 90792 — MDM and prescribing intent must be explicit

08. Reimbursement Insights for 2026
Understanding why reimbursement varies and what you actually control is the difference between reactive billing and proactive revenue management. Psychiatric evaluation codes reimburse at meaningful rates, but the amount you receive depends on several factors that extend well beyond the code itself.
💡 Commercial Payer Rates vs. Medicare in 2026 Medicare rates provide a useful floor for comparison, but most commercial payers reimburse psychiatric evaluation codes at notably higher rates. The 90791 to 90792 reimbursement gap also tends to be larger with commercial payers than with Medicare — making accurate code selection even more financially meaningful in commercial insurance-heavy practices. If you are unsure of your contracted rates for 90791 and 90792 with each payer, requesting a fee schedule review is a worthwhile exercise. Practices regularly discover that they are leaving per-evaluation revenue on the table due to billing 90791 when their encounters qualify for 90792. |

09. How Professional Behavioral Health Billing Services Help
Psychiatric billing is not general medical billing. The evaluation codes, the documentation standards, the payer-specific prior authorization rules, and the credentialing requirements for 90792 providers all require behavioral health billing expertise that general RCM companies rarely have. Here's what changes when you partner with a specialist:
Healthcare providers deserve to focus on clinical care — not on payer portals, prior auth phone trees, and denial appeal paperwork. When psychiatric billing is handled by specialists with behavioral health expertise, the financial results are measurable: higher clean claim rates, faster payment cycles, lower denial rates, and more time reclaimed for patient care.

11. FAQ — 6 Most-Asked Questions About CPT 90791 & 90792
These are the questions psychiatrists, psychologists, therapists, and behavioral health billing teams ask most about psychiatric evaluation codes in 2026. Each answer is written for direct use by providers and optimized for AI search and Google's People Also Ask.
Q1: What is CPT 90791 used for?
CPT 90791 is used for a comprehensive psychiatric diagnostic evaluation that does not include medical services. It is the appropriate code when a licensed mental health clinician — psychiatrist, psychologist, therapist, or counselor — conducts an initial or comprehensive reassessment that covers psychiatric history, mental status examination, DSM-5 diagnosis, and treatment planning, without incorporating medication management, prescribing decisions, or other medical services into the same encounter.
Q2: What is CPT 90792 used for?
CPT 90792 is used when the psychiatric diagnostic evaluation also includes a medical services component — most commonly medication evaluation, medication management, prescribing decisions, physical examination findings, or complex medical decision making related to psychiatric care. It is restricted to providers with prescriptive authority, including psychiatrists, psychiatric nurse practitioners, psychiatric physician assistants, and other physicians practicing in psychiatric settings.
Q3: Can therapists bill CPT 90792?
No. CPT 90792 is restricted to providers with prescriptive authority and medical evaluation privileges. Licensed clinical social workers, licensed professional counselors, licensed marriage and family therapists, and psychologists without prescriptive authority are not eligible to bill CPT 90792, regardless of the complexity of the evaluation. Non-prescribers should use CPT 90791 for psychiatric diagnostic evaluations.
Q4: Does CPT 90792 include medication management?
CPT 90792 includes a medication evaluation or medication management component — it does not separately reimburse for medication management as a standalone service. The "medical services" in 90792 typically encompasses reviewing current medications, evaluating the need for psychiatric medication, discussing prescribing risks and benefits with the patient, and documenting a medication plan or prescribing intent. The evaluation and the medical services are bundled into a single 90792 code.
Q5: Why are psychiatric evaluation claims denied?
The most common denial reasons for 90791 and 90792 claims include: incomplete mental status examination documentation, missing or unspecified ICD-10 diagnosis codes, non-prescribers submitting CPT 90792, documentation of 90792 that does not include the required medical services component, missing prior authorization for the evaluation, and billing evaluation codes (90791/90792) for what should be coded as ongoing psychotherapy sessions (90832/90834/90837).
Q6: How can behavioral health providers improve billing accuracy for psychiatric evaluations?
Start with documentation structure: use evaluation templates that include all required elements for the selected code, document specific ICD-10-aligned diagnoses instead of unspecified codes, and ensure psychiatrists explicitly document medication review and medical decision making when billing 90792. On the operations side: verify provider eligibility before code selection, confirm prior authorization requirements with each payer, and submit claims within 5 business days. Partnering with a behavioral health billing specialist who understands the 90791/90792 distinction consistently produces the highest improvement in clean claim rates and revenue per evaluation.
