CPT Code 90837: Complete Guide to 60 Minute Psychotherapy Billing 2026
Psychotherapy billing has never been more demanding. Across the United States, therapists, psychologists, psychiatrists, counselors, and behavioral health organizations are navigating a rapidly changing reimbursement environment where even minor documentation gaps translate directly into lost revenue.
CPT Code 90837 is one of the most widely billed psychotherapy codes in outpatient behavioral health settings. It represents a 60 minute individual psychotherapy session and carries some of the highest reimbursement potential in the mental health CPT code family. Yet it also draws intense scrutiny from commercial payers, Medicare, and Medicaid managed care organizations due to its time and documentation requirements.
Insurance payers are increasingly sophisticated in their auditing approaches. Claim denial rates for psychotherapy services have climbed steadily over recent years. Behavioral health providers face mounting administrative burdens, prior authorization requirements, and complex documentation expectations that can overwhelm practices without dedicated billing expertise.
Revenue leakage from 90837 billing errors is a significant but often underestimated problem. Incorrect session duration documentation, missing treatment goals, absent medical necessity language, and modifier errors can all trigger denials, payment delays, or post payment audits that put provider revenues and compliance records at risk.
This guide was written to help therapists, behavioral health clinics, and healthcare organizations understand CPT 90837 completely, bill it correctly, protect reimbursement, and operate with full compliance confidence in 2026 and beyond.

Quick Answer: What Is CPT Code 90837?
CPT Code 90837 is the Current Procedural Terminology code used to bill individual psychotherapy sessions lasting 53 minutes or more (typically a full 60 minute session). It is used by licensed mental health professionals to report face to face therapeutic services - focused on the evaluation and treatment of mental health conditions.
The American Medical Association defines CPT 90837 as an individual psychotherapy service with a session time of 60 minutes. This code is designed for use in outpatient settings and represents a standard full length therapy session that allows sufficient time for in depth clinical assessment, therapeutic intervention, and progress evaluation.
Who Can Bill CPT 90837?
The following licensed professionals are generally authorized to bill CPT 90837, subject to state licensure and payer credentialing requirements:
- Licensed Clinical Social Workers (LCSWs)
- Licensed Professional Counselors (LPCs)
- Licensed Marriage and Family Therapists (LMFTs)
- Psychologists (PhD, PsyD)
- Psychiatrists (MD, DO) when providing psychotherapy
- Advanced Practice Registered Nurses with psychiatric specialty (PMHNPs)
- Licensed Mental Health Counselors (LMHCs)
- Certified Addiction Counselors with appropriate licensure
Billing eligibility depends on payer specific credentialing, state licensure status, and whether the provider is enrolled with the relevant insurance plan. Incident to billing rules may apply in certain outpatient settings under Medicare when services are rendered under physician supervision.
Clinical Significance of CPT 90837
CPT 90837 is specifically reserved for longer, more clinically intensive sessions. Payers expect that the additional session time compared to shorter codes like 90832 or 90834 reflects genuine therapeutic need, greater clinical complexity, or treatment goals that require extended therapeutic engagement. This code is not simply a billing preference. It must be clinically justified.
CPT 90837 Time Requirements
Time requirements are one of the most common sources of CPT 90837 billing errors and claim denials. Understanding the precise timing standards for this code is essential for every provider and billing team.
| Time Threshold | Billing Eligibility | Documentation Requirement |
|---|---|---|
| Less than 38 minutes | Not billable as 90832 | Session does not meet minimum threshold |
| 38 to 52 minutes | Bill as CPT 90834 | Document actual session duration |
| 53 minutes or more | Bill as CPT 90837 | Document actual session start and end time |
| 75 minutes or more | Consider add on code +90785 | Document medical necessity for extended session |
Compliance Alert: Session Timing Documentation
Providers must document actual session start and end times in clinical notes for every 90837 claim. Simply writing '60 minute session' without specific timestamps is not sufficient for audit defense and may be challenged by payer reviewers.
Common Timing Mistakes to Avoid
- Billing 90837 when the actual session was only 45 to 50 minutes
- Failing to record specific start and end times in session notes
- Including non therapeutic time such as scheduling or phone calls in session duration
- Rounding up session minutes to reach the 53 minute threshold
- Using 90837 for group sessions or family sessions without the patient present
Thorough documentation is the single most powerful defense against claim denials and audit findings for CPT 90837. Each session note must tell a complete clinical story that demonstrates medical necessity, clinical appropriateness, and meaningful therapeutic progress.
CPT 90837 Documentation Checklist
Required Documentation Elements for Every CPT 90837 Claim
- Patient name, date of birth, and insurance member ID
- Session date and specific start and end times
- DSM diagnosis with ICD 10 codes
- Medical necessity statement explaining why the session is clinically indicated
- Current treatment goals and measurable objectives
- Therapeutic modalities and interventions used during the session
- Patient presenting concerns or symptoms addressed in session
- Patient response to therapeutic interventions
- Clinical observations including mood, affect, behavior, and cognition
- Risk assessment including suicidal ideation, homicidal ideation, self harm
- Progress toward treatment goals with specific examples
- Plan for next session and any recommended follow up
- Provider signature with credentials and NPI number
- Supervision notation if applicable (e.g., intern under supervision)
Documentation that meets billing requirements may not always meet audit readiness standards. Payer audits and OIG reviews look for specificity, clinical relevance, and evidence that the treatment is individualized to the patient’s unique needs. Generic, templated notes that use the same language across sessions are a significant audit risk.
- Each note should reflect the specific content of that particular session
- Avoid copy and paste documentation across sessions
- Ensure that progress notes connect clearly to the treatment plan
- Document any changes in patient condition or treatment approach
- Retain all records for at least seven years or longer based on state requirements

90837 Reimbursement Guide
CPT 90837 reimbursement rates vary significantly across payer types, geographic regions, and provider contract terms. Understanding these differences is essential for accurate revenue forecasting and contract negotiation.
| Payer Type | Average Rate Range | Key Factors | Reimbursement Notes |
|---|---|---|---|
| Medicare (National) | $110 to $135 per session | Geographic adjustment, GPCI | Based on Medicare Physician Fee Schedule 2026 |
| Medicaid | $65 to $110 per session | State specific rates, managed care | Varies widely by state; some states require prior auth |
| Commercial Insurance | $120 to $200 per session | Network contract, region, specialty | Negotiated rates vary; out of network rates differ |
| Managed Care Plans | $90 to $160 per session | Capitation, utilization management | May require additional documentation or step therapy |
| Employee Assistance Programs | $70 to $120 per session | Contract terms, session limits | Limited sessions; no diagnosis often required |
| Self Pay / Sliding Scale | Varies by practice policy | Patient financial situation | Provider discretion; not insurance regulated |
Did You Know: Regional Reimbursement Variation
CPT 90837 Medicare reimbursement in New York or California can be 20 to 35 percent higher than rural Midwest rates due to Geographic Practice Cost Index (GPCI) adjustments. Providers should benchmark their rates against regional Medicare fee schedules annually.
CPT 90837 Compared With Other Psychotherapy CPT Codes
Selecting the correct psychotherapy CPT code is not optional. It must reflect actual session time and clinical context. The following comparison chart shows the key differences between the three primary individual psychotherapy codes.
| Factor | CPT 90832 | CPT 90834 | CPT 90837 |
|---|---|---|---|
| Session Duration | 30 minutes (16 to 37 min) | 45 minutes (38 to 52 min) | 60 minutes (53+ min) |
| Clinical Purpose | Brief supportive therapy | Standard therapy session | In depth therapeutic work |
| Documentation Level | Moderate | Standard | Comprehensive |
| Typical Reimbursement | $60 to $95 | $85 to $135 | $110 to $200 |
| Best Used For | Check in sessions, acute crisis support | Regular maintenance therapy | Complex cases, new patients, trauma work |
| Audit Risk | Low to Medium | Medium | High (requires strong docs) |
| Medicare National Rate | Approx $68 to $82 | Approx $90 to $108 | Approx $110 to $135 |
| Add On Code Eligible | Yes (+90785) | Yes (+90785) | Yes (+90785) |
When session time falls near the threshold between two codes, providers should always bill based on actual face to face time and document precisely. Upcoding to 90837 when a session was actually 48 minutes constitutes a compliance violation and creates significant audit and recovery risk.
Understanding where 90837 billing errors originate is the first step toward preventing them. The following are the most common mistakes that lead to denials, underpayments, and compliance risks.
Mistake 1: Missing or Inadequate Session Duration Documentation
Why It Happens: Providers write '60 minute session' without specific timestamps.
Financial Impact: Claims denied or downcoded to 90834 or 90832.
Best Practice: Always document exact start time and end time for every session.
Mistake 2: Medical Necessity Documentation Gaps
Why It Happens: Notes describe what happened in session but not why the session was medically necessary.
Financial Impact: Audit finding, claim recoupment, or denial upon medical review.
Best Practice: Include specific functional impairment language and symptom severity in every note.
Mistake 3: Incorrect or Missing Modifiers
Why It Happens: Telehealth sessions submitted without the GT or 95 modifier as required by payer.
Financial Impact: Automatic denial from payer system based on Place of Service and modifier mismatch.
Best Practice: Maintain a payer specific modifier matrix and update it quarterly.
Mistake 4: Authorization Failures
Why It Happens: Authorization expires mid treatment without provider or staff awareness.
Financial Impact: Provider absorbs full session cost with no payer reimbursement.
Best Practice: Track authorization expiration dates with automated alerts at least 14 days in advance.
Mistake 5: Upcoding Based on Patient Complexity
Why It Happens: Providers bill 90837 based on how complex the patient is rather than actual session time.
Financial Impact: Serious compliance risk including OIG investigation, payer exclusion, and repayment demands.
Best Practice: Always select the CPT code that matches actual documented session time, not clinical complexity.
The expansion of telehealth coverage that began during the COVID 19 public health emergency has led to lasting changes in how CPT 90837 can be billed for virtual sessions. However, telehealth billing for psychotherapy carries its own set of compliance requirements that providers must follow closely in 2026.
| Consideration | Requirement | Common Mistake | Best Practice |
|---|---|---|---|
| Modifier Requirement | Modifier 95 or GT depending on payer | Omitting required modifier | Verify modifier policy with each payer before billing |
| Place of Service Code | POS 02 for telehealth, POS 10 for patient home | Using POS 11 (office) for telehealth | Confirm correct POS code with payer guidelines |
| Documentation | Same standards as in person sessions | Reduced documentation for telehealth | All 90837 documentation requirements apply equally |
| Payer Coverage | Not all payers cover telehealth 90837 | Assuming all plans cover telehealth | Verify telehealth coverage with each payer and plan |
| Audio Only Sessions | Limited coverage; payer specific | Billing audio only as full telehealth | Confirm audio only policy; some payers allow 90832 only |
| Consent Requirements | Written patient consent often required | Missing telehealth consent in file | Obtain and document telehealth consent at intake |
2026 Telehealth Policy Alert
As of 2026, Medicare has extended many telehealth flexibilities for behavioral health through the end of the calendar year. However, commercial payer telehealth policies vary widely. CareRCM recommends verifying telehealth coverage and modifier requirements for every active insurance plan in your practice on at least a quarterly basis.
