Simplify Processes, Maximize Reimbursements, Empower Care

Accurate billing is the backbone of psychiatric practice. In 2026, psychiatry billing is defined by permanent behavioral health telehealth frameworks, new Advanced Primary Care Management (APCM) integrated care codes, strict compliance enforcement, and AI-driven audit systems. 

Psychiatry billing relies on CPT codes to report services, ICD-10-CM codes to justify medical necessity, and HCPCS codes for integrated care and add-on services. E&M level selection follows 2023–2026 CMS rules based on Medical Decision Making (MDM) or total time — with important restrictions when psychotherapy is billed in the same encounter. 

This guide covers the key psychiatry CPT codes, 2026 coding updates, telehealth billing rules, documentation requirements, and common denial prevention strategies. 

Partner with Neolytix to bring precision, efficiency, and expertise to your psychiatry billing operations. 

2026 Psychiatry Coding Updates

APCM Behavioral Health Add-On Codes

New for 2026, APCM behavioral health integration codes support collaborative and integrated care models for psychiatric patients. 

HCPCS Code 

Description 

G0568 

Initial month — Psychiatric Collaborative Care Model (CoCM) 

G0569 

Subsequent months — Psychiatric CoCM 

G0570 

Behavioral Health Integration (BHI) 

2026 billing rules for APCM codes: 

  • Cannot be billed as standalone codes — must be billed alongside APCM base codes G0556–G0558 
  • Must be billed under the same NPI in the same month as the base APCM code 
  • G0568 should only be used once per episode of care 
  • These codes are not time-based 

Telehealth in 2026

Behavioral health telehealth remains broadly supported in 2026, covering psychotherapy, E&M visits, and audio-only services. Audio-only is permitted when the patient lacks video access or declines video. 

Modifier / POS 

Usage 

Modifier 95 

Synchronous video telehealth 

Modifier 93 

Audio-only telehealth 

POS 10 

Patient’s home 

POS 02 

Other telehealth locations 

In-Person Requirement Update: The previously proposed 6-month and 12-month in-person visit requirements for behavioral health telehealth have been delayed or waived under extended telehealth flexibilities in many cases. The rule is not universally enforced as a strict denial trigger, and behavioral health telehealth remains broadly accessible. Policies may vary by payer — best practice is to continue tracking in-person visits for compliance readiness. 

Core Psychiatry CPT Codes (2026)

Psychiatric Diagnostic Evaluation

CPT Code 

Description 

90791 

Psychiatric diagnostic evaluation — without medical services 

90792 

Psychiatric diagnostic evaluation — with medical services 

Critical Coding Rule: If medication is prescribed or managed during the diagnostic evaluation, CPT 90792 must be used. Billing 90791 when medication services are provided creates significant audit risk. This is one of the most frequently miscoded psychiatry encounters. 

Psychotherapy Codes

Psychotherapy codes are time-based. Documentation must include exact start and stop times to support the selected code. 

CPT Code 

Time Range 

Description 

90832 

16–37 minutes 

Psychotherapy 

90834 

38–52 minutes 

Psychotherapy 

90837 

53+ minutes 

Psychotherapy 

Audit Alert: Overuse of CPT 90837 (53+ minutes) is a major payer audit trigger. Ensure that documented session time consistently supports the code billed. Patterns of routine 90837 billing without variability are flagged by AI-driven audit systems. 

Family and Group Therapy

CPT Code 

Description 

90846 

Family psychotherapy without patient present 

90847 

Family psychotherapy with patient present 

90853 

Group psychotherapy 

Crisis Psychotherapy

CPT Code 

Description 

90839 

Crisis psychotherapy — first 60 minutes 

90840 

Crisis psychotherapy — each additional 30 minutes (add-on) 

Crisis psychotherapy requires documentation of an urgent, high-risk intervention. The record must support the clinical necessity for crisis-level care. 

Interactive Complexity Add-On

CPT Code 

Description 

90785 

Interactive complexity — add-on to psychiatric or psychotherapy codes 

CPT 90785 is used when significant communication barriers exist during the encounter — such as interpreter use, legal guardian involvement, or family conflict that complicates the clinical interaction. 

E&M and Psychotherapy Combined Billing

E&M Codes for Psychiatry

CPT Code 

Description 

99202–99205 

New patient office visits 

99212–99215 

Established patient office visits 

Psychotherapy Add-On Codes (Used with E&M)

When psychotherapy is provided during the same encounter as an E&M service, these add-on codes are used — not the standalone psychotherapy codes. 

CPT Code 

Time Range 

90833 

16–37 minutes of psychotherapy 

90836 

38–52 minutes of psychotherapy 

90838 

53+ minutes of psychotherapy 

Critical Compliance Rule: E&M level can be selected based on MDM or total time. However, when an E&M is billed with psychotherapy, the time spent on psychotherapy cannot be counted toward the E&M time. Selecting E&M level based on MDM — rather than total time — is the safest approach when psychotherapy add-on codes are also billed. 

Common ICD-10-CM Codes in Psychiatry (2026)

ICD-10-CM Code 

Description 

F32.x 

Major depressive disorder, single episode 

F33.x 

Major depressive disorder, recurrent 

F41.1 

Generalized anxiety disorder 

F31.x 

Bipolar disorder 

F90.x 

Attention-deficit hyperactivity disorder (ADHD) 

F43.10 

Post-traumatic stress disorder (PTSD), unspecified 

F51.01 

Primary insomnia 

Documentation Requirements for Psychiatry Billing

Strong, encounter-specific documentation is essential for compliance, audit readiness, and clean claim submission. Every psychiatry encounter should include: 

  • Exact session times — start and stop times (e.g., 10:05 AM to 10:52 AM), required for all time-based codes 
  • Medical necessity — clearly linking symptoms, diagnosis, and the treatment provided 
  • Risk assessment — documentation of suicide risk, violence risk, and functional status 
  • Separate documentation for E&M and psychotherapy when both are billed in the same encounter 
  • Telehealth-specific documentation when applicable (see below) 

Audit Risk: Avoid copy-paste clinical notes. AI-driven audit systems actively flag templated or duplicated documentation as a compliance concern across behavioral health claims. 

Telehealth Documentation Requirements

For telehealth encounters, records must also include the telehealth platform used, documented patient consent, patient location at time of service, modality (audio-only or video), and the reason for audio-only when video was not used. 

42 CFR Part 2 Compliance Update (Effective February 16, 2026)

This update applies to Substance Use Disorder (SUD) records and brings 42 CFR Part 2 into closer alignment with HIPAA standards. 

Key changes: 

  • A single patient consent for treatment, payment, and healthcare operations is now permitted 
  • Practices must update their Notice of Privacy Practices accordingly 

Billing impact: Missing or outdated consent documentation for SUD-related services can create compliance risk and contribute to claim issues. Audit your consent workflows before February 2026 if not already completed. 

Common Psychiatry Billing Denials

  • Missing exact time documentation for time-based psychotherapy codes 
  • Incorrect use of 90791 when medication services were provided (should be 90792) 
  • Missing or incorrect telehealth modifiers (95 or 93) or POS codes 
  • Time overlap between E&M and psychotherapy — time counted twice 
  • Incorrect or non-specific ICD-10-CM diagnosis codes 
  • Lack of documented medical necessity 
  • Overuse of CPT 90837 without supporting session time documentation 

Denial Prevention Strategies

  • Document exact start and stop times for every time-based service at the point of care 
  • Use CPT 90792 (not 90791) whenever medication is prescribed or managed 
  • Select E&M level based on MDM when psychotherapy is also billed in the same encounter 
  • Apply correct telehealth modifiers and POS codes for every virtual visit 
  • Maintain patient-specific, individualized documentation — avoid copy-paste notes 
  • Track APCM episodes correctly to ensure G0568 is not used more than once per episode 
  • Validate modifier and POS accuracy before claim submission 

Psychiatry Billing Workflow

  1. Patient Registration & Eligibility Verification — Confirm insurance coverage and behavioral health benefits 
  2. Telehealth Eligibility Check — Verify payer coverage for video or audio-only services before the visit
  3. Diagnostic Evaluation — Bill CPT 90792 if medication is involved; 90791 if evaluation only 
  4. Therapy or Medication Management — Document session type and duration with exact times 
  5. Medical Coding — Assign CPT, ICD-10-CM, HCPCS, and modifiers based on documentation
  6. Claim Submission — Submit claims electronically with all required modifiers and POS codes 
  7. Payment Posting — Post insurance payments to patient accounts 
  8. Denial Management — Review denied claims, identify root causes, correct, and resubmit

Frequently Asked Questions

What is the difference between CPT 90791 and 90792?

CPT 90791 is used for a psychiatric diagnostic evaluation without medical services. CPT 90792 is used when medical services — including medication prescription or management — are part of the evaluation. Using 90791 when medication is prescribed creates significant audit risk and is one of the most commonly miscoded psychiatry encounters.

When both an E&M service and psychotherapy are provided during the same encounter, the E&M code (99202–99215) is billed with a psychotherapy add-on code (90833, 90836, or 90838) based on the duration of psychotherapy. The time spent on psychotherapy cannot be counted toward the E&M level — selecting E&M level based on MDM rather than total time is the safest approach. 

Modifier 95 is used for synchronous video telehealth visits. Modifier 93 is used for audio-only services when the patient lacks video access or declines video. Place of Service 10 applies when the patient is in their home; POS 02 applies for other telehealth locations. All four elements must be correct for the claim to process accurately.

Effective February 16, 2026, 42 CFR Part 2 aligns more closely with HIPAA, allowing a single patient consent to cover treatment, payment, and healthcare operations for Substance Use Disorder records. Practices must update their Notice of Privacy Practices. Missing consent documentation for SUD-related services can create compliance risk and contribute to claim denials. 

The most frequent psychiatry denials involve missing exact session time documentation, incorrect use of 90791 vs. 90792, missing or incorrect telehealth modifiers, time overlap between E&M and psychotherapy, and overuse of CPT 90837 without supporting documentation. Documenting exact start and stop times, selecting E&M based on MDM when psychotherapy is also billed, and validating modifiers before submission are the most effective prevention strategies.
