What is CPT code 90792 and how is it billed?
CPT code 90792 is a psychiatric diagnostic evaluation with medical services, used by prescribers to bill the initial intake that establishes a diagnosis and treatment plan. It covers the biopsychosocial assessment, mental status exam, medical history review, and clinical recommendations that can include prescriptions or ordered diagnostics. Most payers cover it once per episode of care, with re-evaluations allowed after an extended break in treatment.
- Who bills 90792: Only prescribers, meaning psychiatrists, psychiatric nurse practitioners, and physician assistants; non-prescribers use 90791 instead.
- How long a 90792 evaluation runs: 90792 is not strictly time-based, but complete evaluations typically take 45 to 90 minutes and are judged on assessment content, not clock time.
- How often 90792 can be billed: Once per episode of care per provider, with Medicare treating a roughly six-month treatment break as the threshold for a repeat evaluation.
What Does CPT 90792 Cover?
CPT 90792 covers a psychiatric diagnostic evaluation with medical services, meaning the initial intake performed by a prescriber that includes a biopsychosocial assessment, a mental status exam, medical history review, diagnostics ordered when clinically indicated, and treatment recommendations that can include prescriptions. It establishes the diagnosis and treatment plan for the episode of care.
The code is defined in the American Medical Association’s CPT code set and has been in place since the 2013 rebuild of the psychiatric coding structure, when 90792 was introduced alongside 90791 to distinguish evaluations that include medical services from those that do not.
In practice, 90792 is typically the first visit in an episode of care. The prescriber gathers psychiatric, medical, family, developmental, and social history; performs a mental status exam; arrives at a working DSM-5-TR diagnosis; and lays out a treatment plan that later visits build on. That plan may include medication management alone, psychotherapy alone, or a combination of both.
The medical component is what makes 90792 different from 90791. When a prescriber reviews prior lab work, orders new diagnostics, considers medication contraindications, or writes a prescription during the evaluation, that is the medical service the code captures. Without documented medical elements in the note, a payer may downgrade the claim to the 90791 rate, which pays less. That downgrade risk is the single biggest reason accurate 90792 documentation matters from day one.
How Long Does a 90792 Evaluation Take?
90792 is not strictly time-based. Complete evaluations typically run 45 to 90 minutes, but the code is defined by the completeness of the assessment rather than a specific minute count. The note is judged on what was covered, meaning history, mental status exam, formulation, and plan, not the start-and-stop clock.
That is a meaningful distinction from the psychotherapy codes 90832, 90834, and 90837, which are chosen by documented face-to-face minutes and carry payer-published time ranges. A 30-minute therapy session is 90832; a 45-minute session is 90834; a 60-minute session is 90837. Prescribers coming to 90792 from a therapy background sometimes carry that time-based documentation habit forward, which weakens the claim.
For 90792, the safer approach is to document the assessment content in depth, meaning the history taken, the mental status exam findings observed, the diagnostic formulation reached, and the treatment plan set, rather than logging start and stop times. Payers auditing a 90792 claim look for the substance of the evaluation, not its duration.
A useful test: read the note back and ask whether a reviewer could reconstruct what happened in the visit without the timestamps. If the answer is yes, the note is on solid ground. If the note reads like a therapy start-and-stop log with a diagnosis stapled to the end, the claim is exposed to downgrade.
Who Can Bill 90792 vs 90791?
Only prescribers can bill 90792: psychiatrists, psychiatric nurse practitioners, and physician assistants practicing within their scope. Non-prescribing clinicians such as psychologists, licensed clinical social workers, and licensed professional counselors bill 90791 instead, which is the same evaluation without the medical services component. Billing 90792 under a non-prescriber generates automatic denials.
The split follows directly from the code definitions. The AMA CPT code set defines 90792 as a psychiatric diagnostic evaluation with medical services and 90791 as a psychiatric diagnostic evaluation without medical services. A licensed clinical social worker cannot bill 90792 because their scope of practice does not include the medical services 90792 requires. A psychiatric nurse practitioner practicing within their scope can bill 90792 because prescribing and medical assessment are within their license.
| Factor | 90792 (with medical services) | 90791 (without medical services) |
| Provider types | Psychiatrists, psychiatric NPs, PAs | Psychologists, LCSWs, LPCs, LMFTs |
| Includes medical assessment | Yes | No |
| Can order labs and diagnostics | Yes | No |
| Can prescribe medications | Yes | No |
| Frequency limit | Once per episode of care | Once per episode of care |
| Typical reimbursement | Higher (medical component) | Lower (no medical component) |
In our experience matching providers with billing partners across specialty psychiatric practices, wrong-license 90792 claims are one of the most common credentialing-stage errors we see. A group hires a new licensed clinical social worker, adds them to the roster in the billing system, and inherits the 90792 default from a prior prescriber’s profile. Every intake that clinician runs then generates a denial that could have been avoided at setup.

What Documentation Is Required for 90792?
A complete 90792 note documents six things: the biopsychosocial history, mental status exam findings, a DSM-5-TR diagnostic formulation supporting the ICD-10 code on the claim, the medical services performed (history review, diagnostics ordered, medications discussed or prescribed), the initial treatment plan, and the prescriber’s signature with date of service.
Because 90792 is content-defined rather than time-defined, documentation is what separates a paid claim from a denied one. Every 90792 note should include:
- Document a complete biopsychosocial history covering psychiatric, medical, family, developmental, and social factors.
- Record mental status exam findings with observed data, not just conclusions.
- Support the ICD-10 diagnosis on the claim with a DSM-5-TR diagnostic formulation.
- Capture the medical services performed, including history review, any diagnostics ordered, and any medications prescribed.
- Note the initial treatment plan and the follow-up interval.
- Sign the note with the prescriber’s credentials and the date of service.
Providers often come to us after a wave of 90792 downgrades where the payer paid at the 90791 rate. When we help them look at the notes, the common thread is a strong biopsychosocial history and mental status exam with no explicit documentation of the medical service. The evaluation actually included prescribing decisions and diagnostic considerations, but the note never said so. Documenting the medical component explicitly protects the higher reimbursement 90792 supports.
How Often Can You Bill 90792?
90792 is generally billed once per episode of care per provider. Per Medicare’s local coverage article for psychiatry and psychology services (Article A57480), a repeat evaluation is justified only when an extended treatment break of approximately six months has occurred, when the patient requires psychiatric admission, or when mental status changes significantly enough to warrant a fresh diagnostic assessment.
Commercial payers apply their own frequency rules. Some allow a periodic re-evaluation up to once per year when a patient’s clinical situation changes materially, while others follow Medicare’s six-month framework closely. Repeated 90792 claims on the same patient without documented clinical justification draw scrutiny and are a common trigger for medical necessity denials.
The safest posture is to treat every repeat 90792 as an exception that must be defended in the note. If a patient returns after a nine-month break with a significant medication change and a new comorbidity, that is the profile the CMS article contemplates. If the same patient is being seen monthly with stable symptoms, the follow-up visit is an E/M service, not a repeat 90792.
Confirm each plan’s frequency limit at credentialing and document the clinical reason whenever a re-evaluation is billed.
90791 and 90792 denials almost always come down to provider type, documentation of the medical component, and frequency. In our experience matching providers with billing partners, catching these at credentialing prevents most of them. Get matched with vetted psychiatry billing companies, free.
How Much Does 90792 Reimburse in 2026?
90792 typically reimburses at a higher rate than 90791 because it includes the medical service component. Exact allowances depend on Medicare locality under the 2026 CMS Medicare Physician Fee Schedule, individual state Medicaid rates, and commercial payer contracts, so refer to your specific fee schedules and contracts for the current numbers.
The reimbursement gap between 90791 and 90792 is one reason accurate coding matters at the credentialing stage. When a prescriber is enrolled correctly, credentialed at the right taxonomy, and documenting the medical component on every intake, the practice captures the full value of the evaluation. When any one of those pieces is missing, the practice leaves money on the table through undercoding or automatic downgrades.
One question we hear constantly from practice managers is whether it is worth appealing a 90792-to-90791 downgrade. In most cases where the underlying note supports 90792, it is. The dollar difference per evaluation compounds quickly across a practice, and a successful appeal often reveals a documentation habit fix that stops the downgrades at the source.
The reimbursement gap also affects payer mix decisions. Medicare and most commercial plans reimburse 90792 at a materially higher rate than 90791, but some state Medicaid programs pay both at similar levels or apply their own behavioral health fee schedules that compress the gap. A practice heavily weighted toward Medicaid may see a smaller upside from correct 90792 coding than a practice weighted toward Medicare Advantage or commercial payers, which is a useful factor when modeling collections at the practice level.
What Add-On Codes Pair with 90792?
Interactive complexity code 90785 pairs with 90792 when communication factors complicate the evaluation, such as involving a third party, managing sentinel event disclosure, or working with a court-ordered evaluation. Psychotherapy add-on codes (90833, 90836, 90838) do not pair with 90792 because they attach to E/M services instead, and 90792 already includes the medical component.
The 90785 add-on captures the extra work that complexity creates. Common scenarios include an evaluation conducted with a parent or guardian present because the patient is a minor, an evaluation that involves an interpreter, or an evaluation where a disclosure of abuse or self-harm has to be managed within the visit. The add-on requires its own documentation showing the specific complexity factor present.
The same-day rule is straightforward: the same provider generally does not bill 90792 and a separate E/M for the same encounter, because the evaluation already captures the medical service. When psychotherapy follows on a different day, it is coded with the appropriate psychotherapy code on that date, not bundled retroactively into the 90792 note.
For 90792 evaluations delivered by video, most payers require modifier 95 and applicable place-of-service coding. Medicare behavioral telehealth flexibilities are extended through December 31, 2027, and our guide to psychiatry telehealth billing rules covers the current requirements.
Why Do 90792 Claims Get Denied?
The most common 90792 denials fall into five patterns: wrong-license billing, frequency violations, documentation gaps around the medical component, same-day conflicts with other services, and missing telehealth modifiers. Each pattern is preventable at the credentialing and coding setup stage, well before a claim reaches the payer.
- Wrong-license billing, where a non-prescriber submits 90792 instead of 90791.
- Frequency violations, where a repeat 90792 is billed without documented clinical justification.
- Documentation gaps, where the medical service distinguishing 90792 from 90791 is not captured in the note.
- Same-day conflicts, where a separate E/M visit is billed on the same date as the evaluation.
- Missing modifier 95 on telehealth evaluations when the payer requires it.
Across the billing companies we vet, a recurring pattern separates practices that keep 90792 clean from those that fight denials month after month: the clean practices map each provider to the evaluation code their license supports at credentialing, track payer frequency limits in the billing system, and audit a random sample of 90792 notes each month for the medical component. The practices that struggle treat 90792 like a template and only look at denials after the fact.

Frequently Asked Questions
CPT 90792 is a psychiatric diagnostic evaluation that includes medical services. It is the intake assessment performed by a prescriber, covering the diagnostic interview, biopsychosocial history, mental status exam, medical history review, diagnostics ordered when indicated, and treatment recommendations that may include prescriptions. It establishes the diagnosis and treatment plan for the episode of care.
Only prescribers can bill 90792: psychiatrists, psychiatric nurse practitioners, and physician assistants practicing within their scope. Non-prescribing clinicians such as psychologists, licensed clinical social workers, and licensed professional counselors use 90791 instead, which is the same evaluation without the medical services component. Billing 90792 under a non-prescriber generates automatic denials.
Yes. A psychiatric nurse practitioner practicing within their scope of licensure can bill 90792 because the code includes medical services that match a prescriber’s role, including medication management and diagnostic ordering. Verify credentialing, payer enrollment, and taxonomy code for each plan the practice bills to avoid setup-stage denials.
90792 is not strictly time-based. Complete evaluations typically run 45 to 90 minutes, but the code is defined by the completeness of the assessment rather than a specific minute count. The note is judged on the content of the evaluation, meaning history, mental status exam, formulation, and plan, not the start-and-stop clock.
90792 is generally billed once per episode of care per provider. Medicare’s local coverage article A57480 treats an extended treatment break of approximately six months, a psychiatric admission, or a significant mental status change as the point where a repeat evaluation may be justified. Commercial payer rules vary and should be verified.
A complete 90792 note documents a biopsychosocial history, mental status exam findings, a DSM-5-TR diagnostic formulation supporting the ICD-10 code, the medical services performed (history review, diagnostics ordered, medications discussed or prescribed), the initial treatment plan, and the prescriber’s signature with date of service. Missing medical service documentation is the top cause of downgrades.
Psychotherapy add-on codes such as 90833 are designed to pair with E/M services, not with 90792, because 90792 already includes the medical evaluation. If a prescriber performs an initial evaluation, use 90792 alone. If a prescriber performs a follow-up E/M with psychotherapy, use the appropriate E/M code plus 90833, 90836, or 90838.
