CPT 90837: Psychotherapy 60 Minutes Billing Guide

Understanding CPT 90837

CPT 90837 covers psychotherapy services lasting 53 minutes or more when performed in an outpatient setting. This is the most commonly billed psychotherapy code for standard individual therapy sessions, representing the traditional “therapy hour.” The code applies to face-to-face psychotherapy with the patient and may include communication with family members or caregivers when clinically appropriate and the patient is present for the interaction.

The psychotherapy code family includes 90832 (16-37 minutes), 90834 (38-52 minutes), and 90837 (53+ minutes). Selection depends on the actual face-to-face time spent in psychotherapy, not the total appointment duration. Time spent on documentation, phone calls, or coordination of care outside the patient’s presence does not count toward the psychotherapy time threshold.

Time Requirements and Documentation

The 53-minute minimum for 90837 represents face-to-face psychotherapy time. Providers must document the start and end times of the psychotherapy session or the total psychotherapy minutes. The time documentation is critical because it determines whether 90837 or the lower-level code 90834 (38-52 minutes) applies. A session that runs 50 minutes should be billed as 90834, not rounded up to 90837.

Clinical documentation for 90837 should include the presenting concerns addressed during the session, the psychotherapeutic techniques employed (such as CBT, DBT, psychodynamic, motivational interviewing, or EMDR), the patient’s response to interventions, progress toward treatment plan goals, and the plan for the next session. Documentation should reflect the clinical substance of a 53+ minute encounter, not generic session notes that could apply to any patient.

The treatment plan must establish specific, measurable goals with anticipated timelines. Examples include “Reduce PHQ-9 score from 18 to below 10 within 12 sessions” or “Develop and practice 3 distress tolerance skills for use during panic episodes within 8 sessions.” Progress notes should reference these goals and document specific movement toward or barriers to achieving them.

Billing With E/M Services

When psychotherapy is provided on the same day as an E/M service by the same provider, add-on codes 90833, 90836, or 90838 are used instead of standalone psychotherapy codes. The add-on code selection depends on the psychotherapy time: 90833 for 16-37 minutes, 90836 for 38-52 minutes, and 90838 for 53+ minutes of psychotherapy performed alongside the E/M service.

Psychiatrists commonly bill a combination of E/M (for medication management) and add-on psychotherapy. For example, a psychiatrist who spends 15 minutes on medication review and 55 minutes on psychotherapy would bill an appropriate E/M code plus 90838. The documentation must clearly separate the E/M component (medication review, physical assessment, prescription management) from the psychotherapy component (therapeutic intervention).

Psychologists, licensed clinical social workers, and licensed professional counselors typically bill standalone psychotherapy codes (90837) rather than add-on codes, since they generally do not perform E/M services. Some states allow advanced practice psychiatric nurses to bill both E/M and psychotherapy codes based on their scope of practice.

Reimbursement Rates

Medicare reimbursement for 90837 in 2026 averages $130-$150 depending on geographic locality. This rate positions individual psychotherapy as a moderate-revenue service, requiring efficient scheduling to maintain practice viability. A therapist seeing 6-7 patients per day at Medicare rates generates $780-$1,050 in daily revenue from 90837 alone.

Commercial payer rates for 90837 range from $120-$200, with significant variation by payer, credential type, and region. In-network rates are typically lower than out-of-network rates, though out-of-network billing requires patient payment of the difference. Mental health parity laws require commercial payers to reimburse behavioral health services at rates comparable to medical services, though enforcement and interpretation vary.

Telehealth has expanded access to psychotherapy services and is billable using 90837 with modifier 95 for synchronous video sessions. Most payers now cover telehealth psychotherapy at the same rate as in-person sessions, a significant change from pre-pandemic policies. Audio-only sessions may use 90837 with modifier FQ, though coverage and reimbursement vary by payer.

Prior Authorization and Session Limits

Many commercial payers require prior authorization for psychotherapy beyond an initial evaluation period. Authorization requests typically require a treatment plan with specific goals, baseline assessment scores (PHQ-9, GAD-7, PCL-5), the anticipated frequency and duration of treatment, and the specific modality being employed. Practices should submit authorization requests 2-3 weeks before the current authorization expires to prevent gaps in coverage.

Some payers impose session limits, typically 20-30 sessions per calendar year. When patients require treatment beyond these limits, the provider must submit a medical necessity review demonstrating ongoing functional impairment, documented progress, and a plan for continued improvement. Successful reviews focus on objective measures of functioning rather than subjective reports of distress.

Medicare does not impose session limits for psychotherapy but requires that each session be medically necessary and that the patient is making progress toward treatment goals. Documentation of a stable or declining clinical picture without modification of the treatment approach may lead to denial of ongoing sessions.

Compliance and Best Practices

Common compliance issues with 90837 include billing for sessions that did not meet the 53-minute threshold, inadequate documentation of the psychotherapeutic intervention, continuing to bill for psychotherapy without a current treatment plan, and billing 90837 when the session consisted primarily of case management or care coordination rather than psychotherapy.

Practices should implement quality assurance processes that include periodic chart audits, time documentation verification, and outcome measure tracking. Using standardized outcome measures (PHQ-9, GAD-7, AUDIT-C, PCL-5) at regular intervals provides objective evidence of treatment effectiveness and supports medical necessity for ongoing sessions.

Credentialing is essential for psychotherapy billing. Each provider must be individually credentialed with every payer they bill. The credentialing process typically takes 60-120 days, during which services may not be billable. Practices should begin credentialing new providers immediately upon hiring to minimize revenue delays.
