CPT Code for Psych Evaluation: Complete 2026 Guide for Behavioral Health Providers

Key Takeaways

• The primary CPT codes for psychiatric diagnostic evaluation in 2026 are 90791 (without medical services) and 90792 (with medical services), while 96130–96133 support psychological testing evaluation services.

• CPT 90791 is used by non-prescribing clinicians such as clinical psychologists, social workers, and counselors, while 90792 is reserved for prescribers (psychiatrists, nurse practitioner, physician assistant) who incorporate a medical services component.

• Documentation must clearly support time spent, clinical decision making, and medical necessity to survive audits and prevent recoupments—vague notes are a primary denial trigger.

• Payers increasingly bundle, downcode, or deny psych evaluation claims, making accurate coding, proper modifier use, and correct sequencing with evaluation and management and testing codes essential.

• Cipher Billing, a behavioral health-only RCM partner since 2017, maintains a 1.88% write-off rate and 96% first-pass record approval by optimizing psych evaluation coding and documentation from day one.

Introduction to CPT Codes for Psych Evaluation

Understanding the correct cpt code for psych evaluation is foundational to behavioral health billing. In billing terms, a psychiatric evaluation refers to the comprehensive initial assessment that establishes diagnoses, informs treatment planning, and documents medical necessity for the entire episode of care. Get this wrong, and underpayment or denials can cascade through every subsequent claim.

As of 2026, the core intake and diagnostic codes remain 90791 for initial psychiatric diagnostic evaluation without medical services and 90792 for diagnostic evaluation with medical services. These codes are distinct from the 96130–96133 family, which covers psychological testing and neuropsychological testing evaluation—interpretive work following standardized test results rather than broad intake assessments. Confusing these code families is one of the fastest routes to claim denials.

Psychiatric evaluations anchor services rendered in substance use treatment, residential facilities, partial hospitalization programs (PHP), intensive outpatient programs (IOP), and outpatient mental health settings. Coding these evaluations correctly from admission sets the compliance tone for the entire patient stay. At Cipher Billing, we’ve focused exclusively on behavioral health billing since 2017, which means we track the frequent payer policy changes around these codes so facilities can focus on patient care instead of coding updates.

Core CPT Codes for Psychiatric Diagnostic Evaluation (90791 & 90792)

This section focuses specifically on the intake and diagnostic CPT codes used for psychiatric evaluations—not psychotherapy codes or psychological assessments administered via testing protocols.

CPT 90791: Psychiatric Diagnostic Evaluation Without Medical Services

CPT 90791 covers a comprehensive psychiatric diagnostic evaluation performed by non-prescribing clinicians. This includes:

• Clinical psychologists

• Licensed clinical social workers (LCSWs)

• Licensed marriage and family therapists (LMFTs)

• Licensed professional counselors

The evaluation encompasses biopsychosocial history gathering, mental status examination (MSE), risk assessment for suicidality or violence, DSM-5-TR diagnostic formulation, and treatment planning. It explicitly excludes prescription writing, medication management, or independent medical assessment like lab orders or physical exams.

CPT 90792: Psychiatric Diagnostic Evaluation With Medical Services

CPT 90792 applies to prescribers—psychiatrists, psychiatric nurse practitioners, and physician assistants—who incorporate medical decision making into the evaluation. Beyond the psychiatric assessment, 90792 documentation includes:

• Review of medical history and systems

• Physical examination (when clinically indicated)

• Lab or imaging interpretation

• Medication-related clinical decision making

This code is appropriate for admission evaluations in detox, medication-assisted treatment (MAT), or substance use disorder programs where medical integration is central to clinical care.

2026 Reimbursement Ranges

Code

Medicare National Average

Commercial Payer Rates

90791

$150–$170

20–50% higher

90792

$160–$190

20–50% higher

Rates vary by state, payer mix, and geographic wage indices. Urban areas typically see uplifts while rural settings face downward adjustments.

Important: 90791 and 90792 are generally not reported together on the same date for the same patient by the same provider. Pairing with evaluation and management e/m codes requires distinct service separation to avoid bundling denials.

When to Use 90791 vs 90792 in Psych Evaluation

Accurate code selection between 90791 and 90792 is one of the most frequent audit targets in behavioral health billing. Payers recover significant revenue when facilities bill 90792 without documented medical services, downcoding to 90791 and recouping the difference—sometimes 10–30% per claim in audited practices.

Criteria for 90791

Use 90791 when:

• A non-prescribing clinician performs the evaluation

• No physical exam is conducted

• No independent medical services are documented

• Focus remains on psychosocial and psychiatric assessment and formulation

• No medication decisions are made

Criteria for 90792

Use 90792 when:

• A prescriber (psychiatrist, NP, PA) performs the evaluation

• Medical history and review of systems are documented

• Physical exam or systems review is completed

• Meaningful review of labs, imaging, or medical record occurs

• Medication-related clinical decision making is documented

Clinical Examples

Example 1: IOP Therapist Intake A licensed clinical social worker conducts a 60-minute intake on a new patient with anxiety and trauma history. The evaluation includes comprehensive biopsychosocial history, MSE noting coherent thought process and low suicide risk, DSM-5-TR diagnosis of F41.1 (generalized anxiety disorder), and initial treatment planning. Bill 90791.

Example 2: Psychiatrist MAT Evaluation The same patient later sees a psychiatrist for benzodiazepine evaluation. The psychiatrist documents medical history, reviews ECG for cardiac risks, assesses medication interactions with the patient’s current prescriptions, and develops a medication plan. Bill 90792.

Example 3: Detox Admission A psychiatric NP performs an admission evaluation for a patient entering detox for opioid use disorder. Documentation includes physical exam findings, liver function test review for psychotropic clearance, polypharmacy risk assessment, and MAT initiation plan. Bill 90792.

If medical services are minimal or undocumented, payers will downcode 90792 to 90791, resulting in revenue loss and potential compliance risk.

Time, Documentation, and E/M Overlap for Psych Evaluation Codes

Although 90791 and 90792 are not formally time based codes like psychotherapy, payers increasingly expect reasonable encounter lengths (typically 45–90 minutes) and robust documentation to justify reimbursement.

Required Documentation Elements

A compliant psychiatric evaluation note should include:

• History of present illness (HPI) with symptom chronology

• Past psychiatric history including prior treatment and hospitalizations

• Medical history relevant to psychiatric care

• Substance use history with current and past use patterns

• Family and social history

• Mental status exam covering appearance through insight/judgment

• Risk assessment with explicit stratification (low/moderate/high)

• Diagnostic formulation linking clinical data to DSM-5-TR criteria

• Treatment plan with measurable goals

Additional Requirements for 90792

When billing 90792, documentation must also include:

• Physical exam findings or relevant systems review

• Lab or imaging integration (e.g., LFTs for psychotropic clearance)

• Medication rationale and risk discussion

• Medical decision making complexity

E/M Code Interaction

CPT 90792 is intended for comprehensive initial evaluation—not routine medication checks. For follow-up medication management visits, use evaluation and management codes (99212–99215) based on time or medical decision making complexity.

If a provider bills both an e m service and a same-day psychotherapy add-on (90833/90836/90838), modifier 25 is required for significant, separately identifiable work. However, 90791/90792 typically stand alone for primary psych evaluations and should not be paired with E/M for the same problem without clear clinical separation.

CPT Codes for Psychological Testing Evaluation (96130–96133)

Broad psychiatric diagnostic evaluations (90791/90792) differ fundamentally from testing-focused psychological testing evaluation services that rely on the 96130–96133 code family.

CPT 96130 and +96131: Psychological Testing Evaluation

• 96130: First hour of psychological testing evaluation by a qualified healthcare professional (QHP)—reimbursed at approximately $124.74

• +96131: Each additional hour (add on codes), requiring a 31-minute minimum threshold

These codes capture integrating clinical data from psychological assessments: test selection, record review, scoring, interpretation, report writing, and interactive feedback to patients and family members.

CPT 96132 and +96133: Neuropsychological Testing Evaluation

• 96132: First hour of neuropsychological testing evaluation by QHP

• +96133: Each additional hour add-on

Neuropsychological test administration and evaluation focus on cognitive domains—memory, executive function, attention—relevant to dementia, traumatic brain injury, or cognitive disorder assessments.

What These Codes Capture

The 96130–96133 family covers non-face to face services professional effort:

• Review of medical records and clinical data

• Test interpretation and integration

• Report writing with standardized test results

• Discussion with patient and family

These codes do not capture raw test administration time, which uses separate codes (96136–96139).

Caution: Facilities frequently misuse 96130–96133 as generic “psych eval codes.” This triggers denials when the work overlaps with intake/diagnostic services that should use 90791/90792. Differentiate clearly between initial evaluation and testing-related evaluations for compliance.

Related Testing and Screening Codes Often Confused with Psych Evaluation

Many payers and healthcare providers confuse screening and test administration codes with full psychiatric evaluations, causing denials and recoupments.

CPT 96127: Brief Standardized Screening

• Covers brief emotional or behavioral assessment using a standardized instrument (PHQ-9, GAD-7)

• Reimbursed at approximately $4.97 per instrument

• Maximum 3 units ($14.91 total) per visit

• Common in primary care and outpatient behavioral health for initial screening

Test Administration Codes

Code

Description

Approximate Rate

96136

First 30 min, provider-administered

$43.94

+96137

Each additional 30 min, provider

96138

First 30 min, technician-administered

$37.73

+96139

Each additional 30 min, technician

Add-on

Minimum threshold is 16 minutes for the first unit. These codes apply when two or more tests are administered.

Billing Workflow and Restrictions

Screening, test administration, and evaluation services represent distinct stages of the assessment workflow:

1. 1Screening (96127): Initial screening identifies concerns

1. 1Administration (96136–96139): Tests administered to gather patient data

1. 1Evaluation (96130–96133): Qualified healthcare professional interprets results

Key rules:

• Do not bill 96127 with 96130/96136/96138 or psychotherapy services on the same day without clear separation

• Use modifier 59 when services provided are truly distinct

• Verify payer-specific bundling rules—Aetna bundles 96127 with evals while Anthem may permit with modifier 59

Telehealth Rules for Psych Evaluation CPT Codes in 2026

Since the expansion of telehealth policies through CMS updates in January 2026, most major payers allow psychiatric evaluations via telehealth with specific modifier and place-of-service requirements.

Medicare Telehealth Coverage

CPT 90791 and 90792 remain on the Medicare telehealth list in 2026, reimbursed at in-person parity when billed correctly. Related codes 96127, 96130, 96136, and 96138 are also approved for telehealth delivery.

Telehealth Billing Requirements

Element

Requirement

Modifiers

95 or GT

Place of Service

02 (non-home) or 10 (home)

Documentation

Audio-visual consent, patient location, clinical rationale

Payer Variability

• Medicare: Full parity with cms guidelines

• Medicaid: Varies by state—some impose reduced rates or site restrictions per medicaid services rules

• Commercial: Generally mirrors Medicare but requires eligibility verification

For psychological testing delivered via telehealth, documentation must confirm standardized tools are tele-compatible and include written reports.

Cipher Billing’s rapid VOB (8–9 minutes) is especially valuable for telehealth intakes. Same-day eligibility verification prevents denied psych evaluation claims before they occur.

Billing, Modifiers, and Common Denial Traps for Psych Evaluations

This section serves as a practical checklist for billing and coding teams to prevent denials on psych evaluation codes in 2026.

Frequent Denial Reasons

1. 1Insufficient medical documentation for 90792 — 40% of behavioral health audits target this issue

1. 1Billing 90791/90792 on the same date as E/M for the same problem without clear separation

1. 1Missing mental health F-codes — claims require ICD-10-CM diagnoses (F10.20 for alcohol use disorder, F32.9 for major depression)

1. 1Frequency abuse — repeat 90791/90792 without documented level-of-care change or medical necessity

1. 1Vague diagnostic formulations — failing to link clinical findings to DSM-5-TR criteria

Modifier Usage

Modifier 25: Use when a distinct, separately identifiable psychiatric evaluation occurs on the same day as an office visits medical encounter. Documentation must clearly delineate the services rendered temporally and clinically.

Telehealth modifiers (95/GT): Required for telehealth delivery; policies differ between Medicare, Medicaid, and commercial payers.

Real-World Denial Examples

Scenario: A psychiatrist performs an initial MAT evaluation but documents only medication selection without comprehensive psychiatric assessment, MSE, or risk assessment. Payer downcodes 90792 to 90791, recouping the difference.

Prevention: Document full psychiatric diagnostic evaluation elements plus medical services component—systems review, lab integration, and medication decision making.

Scenario: An IOP bills 90791 on the same date as 99213 for the same presenting problem without modifier 25 or distinct documentation. Claim denied for bundling.

Prevention: Ensure appropriate codes are selected, documentation clearly separates the distinct service, and modifier 25 is applied when justified.

Documentation Best Practices for Compliant Psych Evaluation Coding

Payers increasingly perform post-payment audits on psych evaluations, focusing on medical necessity and whether the medical record supports the billed CPT code and complexity level.

Documentation Checklist for 90791/90792

• \[ \] History of present illness with symptom chronology

• \[ \] Past psychiatric and substance use history

• \[ \] Medical history relevant to treatment

• \[ \] Family and social history including collateral data

• \[ \] Complete mental status exam (all subsections)

• \[ \] Suicide/violence risk assessment with stratification

• \[ \] DSM-5-TR criteria-linked ICD-10 diagnosis

• \[ \] Treatment plan with measurable goals

Additional Elements for 90792

• \[ \] Physical exam or relevant systems review

• \[ \] Lab/imaging review with clinical integration

• \[ \] Medication rationale with risk documentation (e.g., QT prolongation)

• \[ \] Medical decision making complexity

Time Documentation for Testing Codes

For 96130–96133 and related codes:

• Record start/stop times for each service

• Distinguish face-to-face vs non-face-to-face work

• Document tests administered and scoring methodology

• Include clear documentation of clinical interpretation

Internal Audit Recommendations

Adopt structured note templates aligned with payer requirements. Conduct periodic internal audits before claims submission. Cipher Billing uses prospective chart audits during onboarding to identify missing elements before claims go out—catching coding practices issues that would otherwise result in denials or prior authorization delays.

FAQ: CPT Codes for Psych Evaluation

Can I bill 90791 and 90792 for the same patient on the same day?

For a single provider and single encounter, 90791 and 90792 are not billed together. Payers expect one primary psychiatric diagnostic evaluation code per patient per date of service.

In rare team-based assessments—such as a separate non-prescriber (LCSW) and prescriber (psychiatrist) conducting distinct evaluations on the same date—some payers may allow both codes with clear documentation and separate notes. This is payer-specific and requires verification before billing. Use Cipher Billing or internal compliance teams to confirm any exceptions.

How often can I bill a psychiatric diagnostic evaluation for an existing patient?

CPT 90791 and 90792 are intended for initial or re-admission evaluations, not routine follow-ups. Frequency limits vary by payer and program type—UnitedHealthcare, for example, often limits to one per episode without documented medical necessity.

Some payers permit a repeat psychiatric evaluation when there is a major change in clinical status (psychosis emergence, new diagnosis, level-of-care transition) that justifies further evaluation. Document clearly why the comprehensive assessment is medically necessary, referencing payer manuals for specific frequency guidelines.

What diagnosis codes should I use with psych evaluation CPT codes?

Psychiatric evaluations require mental or behavioral health diagnosis codes (ICD-10-CM F-codes) or relevant substance use conditions. Common examples include:

• F41.1 (Generalized anxiety disorder)

• F32.9 (Major depressive disorder, unspecified)

• F10.20 (Alcohol use disorder, moderate)

The diagnosis must be supported by history, mental status exam, and clinical formulation in the note. Some payers restrict “rule-out” diagnoses—document provisional diagnoses appropriately and follow payer-specific rules.

Can psych evaluations be billed via telehealth at the same rate as in-person visits?

Medicare and many commercial payer rates reimburse 90791 and 90792 at parity with in-person rates in 2026 when billed with correct telehealth modifiers (95 or GT) and place-of-service codes.

Medicaid parity varies by state—some still pay different rates or restrict telehealth settings. Always verify payer-specific telehealth policies before new patient visits. Documentation must include audio-visual connection confirmation, patient location, and informed consent.

How do I know whether to use an E/M code instead of 90792 for a prescriber visit?

CPT 90792 is reserved for comprehensive initial psychiatric diagnostic evaluation that includes medical services. Ongoing medication management visits—reviewing response to treatment, adjusting medications, monitoring side effects—typically use E/M codes (99211–99215) based on time or medical decision making.

If the encounter focuses primarily on follow-up med management rather than comprehensive diagnostic assessment, an E/M code is usually more appropriate than repeating 90792. Follow organizational policy and payer guidance. When uncertain about code selection, consult with billing partners like Cipher Billing to ensure accurate coding and avoid audits.
