Mental health awareness has finally taken the spotlight, driving an unprecedented demand for psychotherapy and behavioral health services.
With this growing demand comes the need for accurate, efficient billing practices that empower providers and ensure patient care isn’t disrupted by administrative burdens.
Psychotherapy billing spans some of the most complex code categories in the AMA codebook — time-based individual therapy codes, psychological testing batteries billed in hours and half-hours, group and family therapy with per-member billing, and a special HIPAA confidentiality designation that most providers don’t fully understand until it creates a compliance problem.

Psychiatric Diagnostic Evaluation: CPT 90791
90791 is the diagnostic evaluation code for non-prescribing providers — therapists, psychologists, LCSWs, LPCs, and counselors. It covers the initial psychiatric assessment: psychiatric history, mental status examination, biopsychosocial evaluation, and treatment plan development. No medication management, no physical exam, no lab orders.
90791 vs. 90792 — Know the Boundary: 90792 is reserved for prescribing providers (psychiatrists, NPs, PAs) who conduct the evaluation and also manage medications or perform other medical services in the same visit. If you are a non-prescribing therapist or psychologist, 90791 is your code. Billing 90792 without prescriptive authority is an audit risk. For full 90792 guidance, see our Psychiatry Billing Guide.
What 90791 Covers
- Comprehensive psychiatric history (presenting problem, history of present illness, past psychiatric history)
- Mental status examination
- Review of prior records and collateral information
- Biopsychosocial assessment
- Formulation and initial treatment planning
- Risk assessment (suicidality, self-harm, homicidality)
Key Rule: 90791 cannot be billed on the same date as an individual psychotherapy code (90832, 90834, 90837) for the same patient. On the first visit, bill 90791 only. Begin psychotherapy billing on subsequent sessions.
When Can You Rebill 90791?
CMS and most payers allow a new 90791 when there is a significant clinical change warranting a full reassessment — a new psychiatric diagnosis, a major change in treatment direction, or a return after a prolonged absence (typically 12+ months). Document the clinical rationale clearly. Do not rebill purely because of a new plan year or insurance reset.
Individual Psychotherapy CPT Codes: 90832, 90834, 90837
Individual psychotherapy codes are time-based. The code you bill is determined by the total face-to-face time spent with the patient in a psychotherapy session — not the scheduled appointment length, not the total encounter time including documentation.
90832 16–37 minutes
90834 38–52 minutes
90837 53+ minutes
Common Error: Billing 90837 for a 45-minute session because it was “scheduled as a 60-minute appointment.” If the face-to-face time was 45 minutes, the correct code is 90834. Overbilling based on scheduled time is an audit trigger.
What Is Included in "Psychotherapy Time"?
For standalone psychotherapy codes (90832, 90834, 90837), the time that counts is the face-to-face time directly with the patient engaged in the psychotherapy service itself. This includes:
- Active therapeutic intervention (CBT, DBT, psychodynamic therapy, etc.)
- Review of progress and treatment adjustments discussed with the patient
- Psychoeducation delivered directly to the patient
Time spent on documentation, phone calls, or review of records before or after the session does not count toward psychotherapy time for standalone codes.
Can You Bill 90837 Twice for a 90-Minute Session?
No. 90837 is the highest standalone individual psychotherapy code and covers any session of 53 minutes or longer. There is no separate 90-minute or 120-minute psychotherapy code, and 90837 cannot be billed twice in one session. For sessions longer than 60 minutes where the additional time involves a medical component, consider a combined E/M + psychotherapy approach using the add-on codes (90833/90836/90838).
What About 90-Minute Group Sessions? Group therapy codes (90853, 90849) also have no separate duration-based tiers. You bill once per group member regardless of whether the session runs 60 or 90 minutes
Psychotherapy Add-On Codes: 90833, 90836, 90838, 90785
Add-on codes are used when a prescribing provider performs both an E/M service and psychotherapy in the same encounter. They cannot be billed alone — they must always be paired with a primary E/M code.
90833 | Any E/M code (99202–99215, 99221–99223, etc.) | 16–37 min | Most common add-on for shorter psychotherapy segments |
90836 | Any E/M code | 38–52 min | Used when 45-min therapy follows an E/M assessment |
90838 | Any E/M code | 53+ min | Highest-reimbursing add-on; requires robust documentation |
90785 | 90832, 90834, 90837, 90833, 90836, 90838, 90839, 90847, 90853 | N/A | Interactive complexity — billed when specific conditions apply |
When to Use 90785 — Interactive Complexity
90785 is an add-on to any psychotherapy code (not just the E/M add-ons) when the encounter involves significantly increased complexity of communication. It applies when at least one of the following conditions is present:
- The patient is a child under 18 with a third party (parent, guardian) who must be engaged in treatment
- The patient uses a language interpreter or communication device
- The patient has a legally authorized representative (guardian, healthcare proxy) in the session
- There is a crisis situation requiring changes in visit or treatment structure
- The patient’s family member or caregiver with their own mental illness is actively incorporated into the session
Documentation Requirement for 90785: The qualifying condition(s) must be explicitly documented in the note. A vague statement like “complex session” will not support the add-on. Name the specific criterion — e.g., “Patient’s mother present as legal guardian and required engagement throughout session” or “Spanish-language interpreter used for entire encounter.”
Crisis Psychotherapy Codes: 90839 & 90840
Crisis psychotherapy codes represent a distinct and higher-intensity service category. They apply when a patient presents in a psychiatric crisis requiring urgent intervention — not simply a difficult session or an escalation in severity.
Code | Description | Time | 2026 Medicare Non-Fac (approx.) |
90839 | Psychotherapy for crisis, first 60 minutes | First 30–74 min | ~$193 |
90840 | Each additional 30 min (add-on to 90839) | Add-on per 30 min | ~$95 |
What Qualifies as a "Crisis"?
CMS defines a mental health crisis as a situation where a patient is experiencing an acute psychiatric disturbance requiring immediate intervention to prevent harm. Qualifying scenarios include:
- Active suicidal ideation with intent or plan
- Acute psychotic break with loss of reality testing
- Severe panic attack or acute dissociative episode requiring immediate management
- Acute domestic violence situation requiring safety planning
- Imminent risk of self-harm or harm to others
Do Not Bill 90839 for: A patient who is distressed but stable, a routine high-acuity session, or an encounter that was difficult but did not require urgent, unplanned intervention. Misapplying crisis codes is a documented audit trigger under OIG work plans.
90839 can be billed the same day as an E/M service if the crisis evaluation occurs separately and is distinct from the psychotherapy crisis intervention. In that case, append modifier -25 to the E/M code to indicate it was a significant, separately identifiable service. However, 90839 cannot be combined with 90832/90834/90837 on the same date for the same patient.
Group & Family Therapy CPT Codes
Family Therapy: 90846 vs. 90847
The distinction here is straightforward but frequently confused in billing:
Code | Patient Present? | Description | 2026 Medicare (approx.) |
90846 | No | Family psychotherapy without patient present (caregiver/family only), 50 min | ~$118 |
90847 | Yes | Family psychotherapy with patient present, 50 min | ~$131 |
90849 | Multiple families | Multiple-family group psychotherapy | ~$52 per member |
Family Therapy: 90846 vs. 90847
The distinction here is straightforward but frequently confused in billing:| Code | Patient Present? | Description | 2026 Medicare (approx.) |
| 90846 | No | Family psychotherapy without patient present (caregiver/family only), 50 min | ~$118 |
| 90847 | Yes | Family psychotherapy with patient present, 50 min | ~$131 |
| 90849 | Multiple families | Multiple-family group psychotherapy | ~$52 per member |
Group Therapy: 90853
90853 covers group psychotherapy sessions that are not multiple-family groups. It is billed once per group member per session — not once for the entire group. If you run a 10-person group, you bill 90853 × 10.
- Each participant must be listed as a separate claim
- Groups must be led by a qualified mental health professional (not a peer support specialist billing under this code)
- Medicare requires a minimum of two patients for a group session
- Group size limits vary by payer — Medicare has no hard cap, but most commercial payers limit to 8–12 participants
- 90785 (interactive complexity) can be appended to 90853 when applicable
Psychological & Neuropsychological Testing CPT Codes (96105–96146)
Psychological testing codes cover a wider range than most providers realize. They span brief screening instruments, developmental assessments, full neuropsychological batteries, and automated digital testing — each with its own billing rules, provider eligibility, and documentation requirements.
Screening & Brief Assessment Codes
CPT Code | Description | Who Can Bill | 2026 Medicare (approx.) |
96110 | Developmental screening with standardized instrument, scoring and documentation (e.g., M-CHAT, ASQ) | Any qualified provider | ~$19 per instrument |
96127 | Brief emotional/behavioral assessment (e.g., PHQ-9, GAD-7, ADHD scale), scoring and documentation per standardized instrument | Any qualified provider | ~$12 per instrument |
96127 Billing Tip: 96127 can be billed multiple times per visit — once per standardized instrument administered. If a provider administers a PHQ-9 and a GAD-7 in the same visit, that is two units of 96127. Many practices leave this revenue on the table by billing it only once.
Developmental & Neurobehavioral Testing
96105 | Assessment of aphasia and cognitive function, interpretation and report, per hour | Per hour | ~$152 |
96112 | Developmental test administration including assessment of motor, language, cognitive, social functions — first hour | First hour | ~$152 |
96113 | Developmental test administration — each additional 30 min (add-on to 96112) | Each 30 min | ~$76 |
96116 | Neurobehavioral status exam (thinking, reasoning, memory, visual spatial abilities, language) by physician or QHP, including MDM — first hour | First hour | ~$155 |
96121 | Neurobehavioral status exam — each additional hour (add-on to 96116) | Each additional hour | ~$118 |
96125 | Standardized cognitive performance testing per hour of QHP time (face-to-face administration and interpretation) | Per hour | ~$152 |
Full Psychological & Neuropsychological Testing Batteries
96130 | Psychological testing evaluation — first hour (integration, interpretation, clinical decision-making, report, patient feedback) | First hour | ~$225 |
96131 | Psychological testing evaluation — each additional hour (add-on) | Each additional hour | ~$121 |
96132 | Neuropsychological testing evaluation — first hour | First hour | ~$225 |
96133 | Neuropsychological testing evaluation — each additional hour (add-on) | Each additional hour | ~$121 |
96136 | Test administration and scoring by psychologist — first 30 min | First 30 min | ~$65 |
96137 | Test administration and scoring by psychologist — each additional 30 min (add-on) | Each 30 min | ~$50 |
96138 | Test administration and scoring by technician — first 30 min | First 30 min | ~$42 |
96139 | Test administration and scoring by technician — each additional 30 min (add-on) | Each 30 min | ~$31 |
96146 | Automated standardized instrument via electronic platform — single instrument, automated result only (no professional interpretation) | Per instrument | ~$19 |
96130/96132 vs. 96136/96138 — Two-Part Structure: A full testing battery requires both types: administration codes (96136–96139) for time spent giving and scoring tests, and evaluation codes (96130 or 96132) for the psychologist’s interpretation, report writing, and feedback. The evaluation code does not include administration time — both must be billed.
96130 vs. 96132 — Psychological vs. Neuropsychological: Use 96132/96133 for neurobehavioral and cognitive batteries (e.g., WAIS, WMS, Halstead-Reitan). Use 96130/96131 for personality, emotional, and behavioral testing (e.g., MMPI-3, PAI, Rorschach). When both types are administered in the same evaluation, both codes can be billed.
Documentation for Testing
- Referral reason and clinical indication (medical necessity)
- Specific tests administered by name and version
- Administration time — start/stop times per session
- Psychologist’s time for integration, interpretation, and report preparation
- Complete written psychological evaluation report in the medical record
- Evidence of feedback session with patient/guardian
- Prior authorization documentation (required by most commercial payers)
Health Behavior Assessment & Intervention Codes (96156–96171)
Health behavior codes are among the most underutilized in behavioral health billing — and among the most misunderstood. These codes are not for psychiatric conditions. They are for patients who have a primary physical health diagnosis (chronic pain, cancer, cardiac disease, diabetes, obesity) and whose behavioral, psychological, or social factors are affecting medical treatment and outcomes.
Critical Distinction: Do not use health behavior codes when the primary diagnosis is a mental health condition (F-codes). These codes require a primary medical ICD-10 diagnosis (e.g., chronic pain M54.x, Type 2 diabetes E11.x, cardiac condition I-codes). If a patient has both a mental health diagnosis and a medical condition, and the session is focused on the medical condition’s behavioral aspects, health behavior codes may apply. When in doubt, document clearly which condition is being addressed.
Health Behavior Assessment
CPT Code | Description | Time | 2026 Medicare (approx.) |
96156 | Health behavior assessment or re-assessment (health-focused clinical interview, behavioral observations, health-oriented questionnaires) — each 30 min face-to-face with patient | Per 30 min | ~$72 |
Health Behavior Intervention — Individual
CPT Code | Description | Time | 2026 Medicare (approx.) |
96158 | Health behavior intervention, individual — initial 30 minutes face-to-face | First 30 min | ~$72 |
96159 | Health behavior intervention, individual — each additional 15 min (add-on to 96158) | Each 15 min | ~$36 |
Health Behavior Intervention — Group & Family
CPT Code | Description | Time | 2026 Medicare (approx.) |
96164 | Health behavior intervention, group (2+ patients) — initial 30 min | First 30 min | ~$25 per member |
96165 | Health behavior intervention, group — each additional 15 min (add-on) | Each 15 min | ~$12 per member |
96167 | Health behavior intervention, family with patient present — initial 30 min | First 30 min | ~$72 |
96168 | Health behavior intervention, family with patient present — each additional 15 min (add-on) | Each 15 min | ~$36 |
96170 | Health behavior intervention, family without patient present — initial 30 min | First 30 min | ~$72 |
96171 | Health behavior intervention, family without patient present — each additional 15 min (add-on) | Each 15 min | ~$36 |
Common Clinical Scenarios for Health Behavior Codes
- Pain psychology sessions addressing coping strategies for chronic pain patients (primary dx: M54.x)
- Behavioral interventions for Type 2 diabetes management — adherence, diet, activity (primary dx: E11.x)
- Psycho-oncology sessions for patients undergoing cancer treatment (primary dx: C-codes)
- Cardiac rehabilitation behavioral health component — stress reduction, lifestyle modification (primary dx: I-codes)
- Pediatric health behavior interventions for obesity or asthma management
E/M + Psychotherapy Combined Billing
When a prescribing provider (psychiatrist, NP, PA) provides both medication management (an E/M service) and psychotherapy in the same encounter, the billing uses a different code set than standalone therapy sessions.
Scenario | Primary Code | Add-On Code |
E/M + 16–37 min psychotherapy | 99212–99215 (established) or 99202–99205 (new) | 90833 |
E/M + 38–52 min psychotherapy | 99212–99215 or 99202–99205 | 90836 |
E/M + 53+ min psychotherapy | 99212–99215 or 99202–99205 | 90838 |
Key Rule — Time Cannot Be Double-Counted: The time spent on psychotherapy cannot also be counted toward the E/M level. When billing both in the same encounter, select the E/M level based on Medical Decision Making (MDM) — not total time — to avoid time overlap errors. This is one of the most common audit triggers in combined psychiatry billing.
Standalone psychotherapy codes (90832, 90834, 90837) and add-on codes (90833, 90836, 90838) are mutually exclusive — never bill both for the same encounter. Non-prescribing therapists (LCSWs, LPCs, psychologists) always use the standalone codes; add-on codes are only for prescribers who also bill an E/M.
HIPAA Psychotherapy Notes: Confidentiality Rules & Billing Implications
Psychotherapy notes have a special protected status under HIPAA that is separate from — and more restrictive than — the protections for general medical records. This distinction affects what you can share with insurers, what patients can access, and what your billing staff can review.
What Are “Psychotherapy Notes” Under HIPAA?
Under 45 CFR §164.501, psychotherapy notes are specifically defined as notes recorded by a mental health professional documenting or analyzing the contents of a conversation during a private counseling session, kept separate from the rest of the patient’s medical record. The definition is narrow:
- Session content notes — the substance of what was discussed in private therapy
- Analysis of conversation content and therapeutic process
- Must be maintained separately from the general medical record to qualify
What Are NOT Psychotherapy Notes (Billable Elements)
The following are explicitly excluded from the psychotherapy notes definition and are part of the regular medical record — they can be shared for treatment, payment, and operations without special authorization:
- Medication prescriptions and monitoring
- Session start and stop times
- Modalities and frequencies of treatment
- Results of clinical tests
- Summary of diagnosis, functional status, and treatment plan
- Symptoms, prognosis, and progress to date
Billing Implication: Insurance companies cannot compel disclosure of psychotherapy notes (the session content) to process a claim. Your billing team should never submit the actual therapy session notes to a payer. Claims are supported by the summary elements listed above — diagnosis, treatment plan, dates of service, and session times — not by the content of the conversation.
Special Authorization Requirement
Under 45 CFR §164.508(a)(2), disclosing psychotherapy notes to a third party requires a separate written patient authorization — a general treatment consent or standard HIPAA authorization is not sufficient. The only exceptions are:
- Use by the originating provider for treatment of the patient who is the subject of the notes
- Use for training programs (mental health provider education)
- Oversight of the originating provider (licensure board review, etc.)
- Defense in a legal action brought by the patient
- Certain public health and safety purposes as required by law
Patient Access Rights
Unlike general medical records — which patients generally have the right to access — psychotherapy notes are one of the few categories explicitly excluded from the HIPAA right of access (45 CFR §164.524(a)(1)(i)). Patients do not have an automatic right to obtain their psychotherapy notes from their provider. Providers may choose to share them but are not required to.
Practical Takeaway: Keep session content notes physically or electronically separate from the rest of the chart. Label them clearly as psychotherapy notes. Train billing staff that these notes never go to payers. Your superbill and claim documentation draw from the non-protected elements — treatment plan summaries, diagnoses, and session times.
Incident-To Billing for Non-Physician Providers
Incident-to billing allows certain non-physician providers — including LCSWs, LPCs, and psychologists in some settings — to bill Medicare under a supervising physician’s or NPP’s NPI. When the rules are met, the service reimburses at 100% of the Medicare fee schedule rather than the 85% rate that applies to independently billing non-physician practitioners.
Medicare Incident-To Requirements
- Established patient only: The supervising physician or NPP must have seen the patient previously and established the treatment plan. Incident-to does not apply to new patients or new presenting problems.
- Direct supervision: The supervising physician or NPP must be physically present in the office suite (not necessarily in the room) and immediately available during the service.
- Integral part of care: The service must be an integral part of the physician’s treatment of the patient — not a separate, independent course of therapy.
- Staff employee or contractor: The non-physician provider must be an employee, leased employee, or independent contractor of the billing physician or practice.
- Outpatient setting only: Incident-to applies in physician office and outpatient settings. It does not apply in hospital outpatient departments, FQHCs, or RHCs.
When Incident-To Does NOT Apply: New patients, new mental health diagnoses being addressed for the first time, any visit where the supervising provider is not present in the office, telehealth sessions (in most circumstances), and hospital outpatient settings. Billing incident-to when these conditions aren’t met is a Medicare compliance violation.
The 85% vs. 100% Decision
When incident-to requirements are met, billing under the supervising physician’s NPI yields 100% of the Medicare fee schedule. Billing independently under the therapist’s own NPI yields 85%. The financial difference is meaningful — on a 90837 session (~$163 non-facility rate), incident-to billing yields approximately $13 more per session. For a practice with high session volume, that compounds significantly.
However, the compliance risk of incorrectly applying incident-to — particularly for new patients or when supervision is not physically present — outweighs the revenue benefit. Establish clear protocols for when each billing method applies before using incident-to billing.
Commercial Payer Rules
Commercial payers do not follow Medicare’s incident-to rules. Each payer has its own credentialing and billing requirements for non-physician mental health providers. Most commercial payers require the non-physician provider to be separately credentialed and to bill under their own NPI. Verify each payer’s requirements — do not assume Medicare incident-to rules apply to commercial plans.
CMS Documentation Requirements for Psychotherapy
CMS documentation requirements for psychotherapy are among the most detailed in mental health billing. Inadequate documentation is the leading cause of psychotherapy claim denials and the primary vulnerability in RAC and OIG audits. Meeting these requirements is not just good practice — it is a compliance requirement.
Core Documentation Elements (All Psychotherapy Codes)
- Date of service — the actual date the session occurred, not the date of documentation
- Start and stop times — the actual clock time the face-to-face session began and ended (e.g., “Session: 2:00 PM – 3:05 PM”). This is mandatory for time-based codes.
- Total face-to-face minutes — stated explicitly in the note, not inferred from the time range
- Presenting problems and symptoms — current mental status, patient-reported concerns, and clinical observations
- Therapeutic modality and interventions used — e.g., “CBT techniques including cognitive restructuring and behavioral activation”; “DBT skills including distress tolerance”
- Patient response to intervention — observable or reported response during the session
- Progress toward treatment plan goals — comparison to prior session, movement toward documented goals
- Assessment of current risk — suicidality, homicidality, self-harm, substance use (required at every session for high-risk patients; recommended for all)
- Plan for next session — proposed focus, any changes to treatment plan, homework or between-session tasks
- Provider credentials and signature — must be a licensed, credentialed provider; include NPI and credentials
Additional Documentation for Add-On Codes
For 90785 (Interactive Complexity)
- Explicitly name the qualifying criterion (third party present, interpreter used, crisis situation, etc.)
- Describe how the complexity factor affected the conduct of the psychotherapy session
For E/M + Psychotherapy Add-On (90833/90836/90838)
- Separate documentation of E/M components (history, exam or MDM, and relevant clinical elements)
- Separate documentation of psychotherapy components with start/stop times for the therapy portion
- Total encounter time with clear delineation of E/M time vs. psychotherapy time (or MDM-based E/M with timed psychotherapy add-on)
- Documentation must support both levels of service independently
For 90839 (Crisis Psychotherapy)
- Description of the presenting crisis — the specific acute disturbance and risk factors
- Clinical rationale for why the situation constitutes a psychiatric emergency
- Interventions specific to crisis management (safety planning, deescalation, coordination of care)
- Disposition — outcome of the crisis intervention (stabilized, referred for higher level of care, etc.)
- Start and stop times
Retention Requirements
CMS requires that medical records for Medicare beneficiaries be retained for a minimum of 5 years from the date of service (or 5 years after the patient turns 18 for minors). Many states have longer requirements. HIPAA mandates records be accessible for 6 years from creation or last use. Maintain the more stringent standard applicable in your state.
“The medical record should be complete and legible, and should include the date, reason for the encounter, appropriate history, physical examination, review of laboratory, x-ray data and other ancillary services, assessment, clinical impression or diagnosis, plan for care and the name of the observer.” — CMS Documentation Guidelines for Evaluation and Management Services
Time-Based Billing Rules for Psychotherapy
Psychotherapy codes are among the few CPT categories that are strictly time-based. The rules below govern which code to use and how to document time correctly.
The “Typical Time” vs. “Actual Time” Distinction
Unlike the 2021 E/M changes that allow billing by typical/threshold time, psychotherapy codes have always required actual documented face-to-face time. You may not use the AMA “typical time” descriptor to justify a code — you must document actual minutes.
Midpoint Rule
When actual time falls at the boundary between two codes, use the midpoint approach:
Actual Session Time | Correct Code | Rationale |
15 minutes or less | Do not bill 90832 | Minimum threshold not met — consider E/M only |
16–37 minutes | 90832 | Falls within the 30-minute code range |
38–52 minutes | 90834 | Falls within the 45-minute code range |
53 minutes or more | 90837 | Meets or exceeds the 60-minute threshold |
If a session runs only 14 minutes: No standalone psychotherapy code is supported. Document the encounter and bill an E/M code if medical services were provided, or do not bill the session separately. Do not “round up” to 90832.
Documenting Time: Best Practice
Do not just write “45-minute session.” Write the actual clock times: “Session began at 10:05 AM and concluded at 10:52 AM (47 minutes of face-to-face psychotherapy).” This eliminates ambiguity and satisfies auditors immediately without requiring further review of the note.
ICD-10 Diagnosis Codes for Psychiatry & Behavioral Health
Every psychotherapy claim requires at least one ICD-10-CM diagnosis code. The diagnosis must be consistent with the presenting problem, support the medical necessity of psychotherapy, and be specific enough to reflect the documented clinical picture.
Depressive Disorders

Specificity Matters: Avoid defaulting to unspecified codes (F32.9, F41.9) when clinical documentation supports a more specific code. Payers increasingly flag high volumes of unspecified codes as evidence of inadequate documentation or upcoding risk, and the specific code better supports medical necessity for psychotherapy.
Modifiers in Psychotherapy Billing
-25 | Significant, separately identifiable E/M service on the same date as a procedure or another service | Required when billing an E/M code on the same date as 90839 or 90791/90792. Tells the payer that the E/M was distinct from the psychotherapy or diagnostic service. |
-GT | Via interactive audio and video telecommunication systems (Medicare) | Required for Medicare telehealth psychotherapy claims. Append to the primary service code. |
-95 | Synchronous telemedicine service rendered via real-time interactive audio and video | Used by commercial payers for telehealth. Check payer preference — some accept 95, some require GT, some require both. |
-FQ | Medicare audio-only telehealth (behavioral health waiver) | Added for Medicare audio-only psychotherapy sessions under the CY 2022+ behavioral health telehealth flexibilities. Must meet conditions for audio-only billing. |
-52 | Reduced services | Use when a session is shorter than the minimum threshold for the next lower code (e.g., 12-minute session billed as 90832 with -52). Rarely used — consider whether billing is appropriate at all. |
-59 | Distinct procedural service | May be needed when billing 90839 and an E/M on the same day if the payer bundles them despite the clinical distinction. |
-HO | Mental health program (not applied to individual claims in most cases) | HCPCS modifier used in some state Medicaid and behavioral health organization billing contexts. Check your state’s Medicaid billing rules. |
Telehealth Psychotherapy Billing
Psychotherapy is one of the most telehealth-friendly specialties in medicine. Following the COVID-19 Public Health Emergency, CMS permanently extended many telehealth flexibilities for behavioral health, and Congress has continued to expand coverage. As of 2026, the following policies apply for Medicare.
Medicare Telehealth Coverage for Behavioral Health (2026)
- Originating site: The patient’s home is a covered originating site for all behavioral health telehealth services — no geographic restriction (rural requirement removed for mental health)
- Audio-video: All standard psychotherapy codes (90832–90837, 90839, 90845, 90846, 90847, 90853) are covered via synchronous audio-video
- Audio-only: Covered for behavioral health under certain conditions — patient must have established a relationship with the provider, must be unable to use video technology, and the provider must document the patient’s lack of access or inability to use video
- In-person requirement: CMS requires that patients receiving audio-only mental health telehealth have an in-person visit with the provider at least once every 12 months (waived through end of 2024 PHE period; confirm current status for 2026)
- Place of Service: Bill POS 02 for telehealth (non-originating site) or POS 10 for telehealth — patient’s home. POS affects the facility vs. non-facility payment rate.
Telehealth Billing Tips
- Document that the patient verbally consented to the telehealth session
- Document the technology used (video platform) and the patient’s location (home, office, etc.)
- For audio-only, document why video was not used (patient lacks technology, technical difficulty, patient preference with documentation of inability)
- Verify state licensing requirements — some states require licensure in the state where the patient is physically located
- Confirm commercial payer telehealth parity laws — most states now have mental health telehealth parity
Reimbursement Rates for Telehealth: Most psychotherapy codes reimburse at the non-facility rate when billed via telehealth with POS 10 (patient’s home), which is typically higher than the facility rate. This is a meaningful revenue difference — verify your POS code is correct on every telehealth claim.
Prior Authorization & Insurance Coverage for Psychotherapy
Prior authorization requirements for psychotherapy vary significantly by payer. Medicare does not require prior authorization for psychotherapy services, but most commercial insurers and Medicaid managed care plans do — at least for ongoing treatment beyond an initial session limit.
What Typically Triggers Prior Auth
- Ongoing individual therapy beyond 8–12 sessions (common commercial trigger)
- High-frequency sessions (more than once per week)
- Intensive outpatient programs (IOP)
- Psychological or neuropsychological testing
- Group therapy in specialized programs
Mental Health Parity Requirements
Under the Mental Health Parity and Addiction Equity Act (MHPAEA), commercial insurers and employer health plans cannot impose more restrictive prior authorization requirements for mental health or substance use disorder services than they impose for medical/surgical services. If your payer requires prior auth for the 10th psychotherapy session but not the 10th physical therapy session, that may be a parity violation.
Practical Tip: When prior authorization is denied, obtain the payer’s reasoning in writing. If the denial cites “not medically necessary” without clinical criteria, request the specific clinical criteria used for the determination — this is required under MHPAEA and most state parity laws. The denial may be overturnable on appeal.
2026 Medicare Updates for Behavioral Health Billing
Reimbursement Rate Changes
The 2026 Medicare Physician Fee Schedule finalized a conversion factor adjustment affecting all services. Psychotherapy codes saw modest rate changes consistent with the overall PFS adjustment. Providers should verify current rates via the CMS PFS Look-Up Tool rather than relying on prior-year rates in practice management systems.
Behavioral Health Integration (BHI) and CCM
CMS continues to support behavioral health integration codes for primary care practices:
Code | Description | 2026 Medicare (approx.) |
99484 | General BHI, 20+ min per month by clinical staff | ~$49 |
99492 | Collaborative Care Model, first 70 min/month (initial) | ~$228 |
99493 | Collaborative Care Model, first 60 min/month (subsequent) | ~$175 |
99494 | Each additional 30 min (add-on to 99492/99493) | ~$88 |
Telehealth Extension
Congress extended behavioral health telehealth flexibilities through 2026, maintaining coverage for audio-only psychotherapy for Medicare beneficiaries who cannot use video technology. The in-person visit requirement for ongoing audio-only patients remains — confirm the current status with CMS as rulemaking continues.
Opioid Treatment Program (OTP) Updates
Counseling services within certified OTP programs continued to receive updated bundled payments. Individual and group counseling codes within OTP follow different billing rules than standard psychotherapy and are governed by the OTP benefit, not the individual psychotherapy benefit.
Common Denial Reasons & How to Prevent Them
Missing start/stop times | Provider notes session duration but not actual clock times | Require EHR templates to include mandatory start/stop time fields; audit 10% of notes monthly |
Time doesn’t support code billed | 90837 billed but documented time was 47 minutes (should be 90834) | Build code-selector logic in EHR based on documented minutes; train providers on time thresholds |
Medical necessity not established | Diagnosis code too vague (F41.9) or note doesn’t describe functional impairment | Use specific ICD-10 codes; note functional impact on work, relationships, activities of daily living |
90839 denied — crisis not documented | Session was intense but not a true psychiatric emergency per payer criteria | Reserve 90839 for true crisis presentations; document specific risk factors and emergency interventions used |
E/M + psychotherapy add-on denied | Note doesn’t distinguish E/M components from therapy components | Use dual-section note templates: one section for E/M (MDM, medications, medical review), one for psychotherapy (therapeutic interventions, progress) |
90785 denied | Interactive complexity condition not named in the note | Add a specific checkbox or field for the qualifying 90785 criterion to the session note template |
Prior authorization required — not obtained | Session count exceeded payer limit; no auth renewal submitted | Set automated alerts in practice management system at 6, 8, and 10 sessions to trigger auth review |
Telehealth modifier missing or incorrect | Claim submitted without -GT or -95, or wrong POS code | Build a telehealth billing checklist; automate POS 10 and modifier application for telehealth appointment types in scheduling system |
Bundling — 90791 with 90832 same day | Diagnostic evaluation and therapy billed together on initial visit | Bill only the diagnostic code on the initial evaluation visit; begin psychotherapy billing on follow-up sessions |
