90837 CPT Code Description: Billing for 60-Minute Psychotherapy

Billing 90837 for every standard psychotherapy session is the most reliable way to invite a payer audit, even when the clinical work is exemplary. While high-reimbursement codes are attractive for revenue, they carry a disproportionate burden of proof that many clinicians fail to meet. A solo practitioner validating their own billing logs faces a different set of risks than an operations manager at a large mental health agency who must ensure hundreds of therapists are not defaulting to the 60-minute code out of habit.

Choosing the correct 90837 cpt code description depends entirely on the face-to-face time recorded, not the complexity of the patient's condition alone. This guide settles the decision-making process for selecting between 45-minute and 60-minute codes by providing the specific time thresholds and documentation requirements needed to defend these claims in 2026. You will identify exactly when to trigger the 60-minute code and how to use your EMR to automate the compliance trail, eliminating the manual guesswork that leads to insurance clawbacks.

Key takeaways

• Use CPT 90837 only when the psychotherapy session duration reaches or exceeds the 53-minute threshold.
• Distinguish 90837 from 90834 by identifying if the session falls into the 38-52 minute or 53+ minute range.
• Ensure documentation explicitly supports the medical necessity for the extended 60-minute duration to avoid audit triggers.
• Automate time-tracking within your EMR to prevent coding errors between 30, 45, and 60-minute session types.

CPT 90837 defines individual psychotherapy for 60-minute sessions

Providers billing for extended individual therapy sessions must use CPT 90837 to ensure accurate reimbursement. In the medical billing landscape of 2026, a Current Procedural Terminology (CPT) code is normally a 5-digit numeric code that identifies specific services provided to a patient. This particular code is reserved for individual psychotherapy and serves as the standard identifier when submitting claims to commercial insurance payers or government programs. By using this specific numeric string, clinicians communicate the nature and complexity of the service to the payer's processing system.

The primary distinction of this code is its association with the duration of the clinical encounter. In professional practice, CPT 90837 is known as the 60-minute psychotherapy code. It is used when a provider delivers individual therapy that significantly exceeds the standard 45-minute session. Selecting this code alerts the insurance carrier that the session required a longer time commitment, which typically results in a higher reimbursement rate compared to shorter session codes. Clinicians should confirm specific reimbursement rates on the payer's current fee schedule, as these figures are subject to change.

The mechanism for utilizing CPT 90837 is based strictly on the time spent face-to-face with the patient. This duration includes the time spent performing the therapeutic intervention, but it excludes administrative tasks such as scheduling, billing, or writing notes after the patient has left the room. To bill correctly, the clinician must document the actual start and stop times or the total face-to-face minutes to prove the session met the required length. This time-based requirement ensures that the billing reflects the actual clinical effort devoted directly to patient care during the encounter.

The 53-minute threshold determines the switch to 90837

To bill correctly for extended psychotherapy sessions in 2026, clinicians must strictly adhere to time-based requirements. The billing threshold for CPT 90837 is 53 minutes or more of face-to-face psychotherapy with the patient. This duration represents the clinical time spent providing the service and does not include administrative tasks such as scheduling or checking insurance eligibility. Providers should confirm specific payer policies on their current portals, as individual insurance carrier requirements for documentation can vary.

The current framework for these time-based billings originated when the psychotherapy CPT codes were revised in 2013. This overhaul moved the industry away from vague session descriptions toward specific time ranges for each code. Before this change, coding was less precise regarding the exact duration of the therapeutic encounter. The 2013 update established clear boundaries, ensuring that each code represents a distinct block of time, which remains the standard for billing practices today.

Under these established guidelines, CPT code 90837 requires a therapy session of at least 53 minutes. This specific number acts as the absolute minimum for the "60-minute" code category. While the code is often colloquially referred to as a 60-minute session, the technical requirement is met once the 53-minute mark is passed. If a session lasts 52 minutes or less, the provider must utilize a different code to accurately reflect the shorter duration of the service provided.

Accurate time tracking is essential for maintaining compliance and securing proper reimbursement. Because 90837 represents the highest level of standard psychotherapy duration, it often receives closer scrutiny during audits. Clinicians must document the exact start and stop times or the total duration in the patient’s record to justify the use of this code. Relying on the 53-minute threshold ensures that the billing reflects the actual intensity and length of the clinical work performed during the encounter.

Differentiate 90837 from 90834 and 90832 by duration

Selecting the correct CPT code for individual psychotherapy requires precise tracking of the time spent face-to-face with the patient. The Current Procedural Terminology (CPT) system uses specific time increments to distinguish between session lengths, and failing to match the documentation to these windows can lead to audits or denied claims. While some CPT codes come in 4-digit and one-letter formats, the primary codes for outpatient psychotherapy are five-digit numeric sequences defined by their duration.

Practitioners must distinguish between 90832, 90834, and 90837 based on the exact minute the session concludes. CPT 90832 is the appropriate choice for brief sessions and has a 37-minute ceiling. If a session lasts at least 16 minutes but does not exceed this 37-minute threshold, it must be billed under 90832. Overbilling a 30-minute session as a higher-level code is a common compliance error that practitioners must avoid through diligent timekeeping.

For standard sessions, CPT 90834 covers individual psychotherapy lasting 38-52 minutes. Within this range, 45 minutes is commonly used as the midpoint/reference duration for CPT 90834. This code serves as the bridge between brief interventions and extended sessions. Practitioners should transition to 90837 only when the session reaches the 53-minute mark. Documentation should reflect the start and stop times to justify the use of the 60-minute code, as insurers often scrutinize 90837 claims more closely than 90834.

The following table summarizes the time ranges and reference points for these three primary codes to assist in rapid selection during the billing process.

CPT Code	Typical Description	Time Range (Minutes)	Midpoint Reference
90832	30-minute psychotherapy	16–37 minutes	30 minutes
90834	45-minute psychotherapy	38–52 minutes	45 minutes
90837	60-minute psychotherapy	53 minutes or longer	60 minutes

Identify cases where 90837 does not apply

Providers must ensure the session duration meets the minimum threshold before applying 90837. This code is reserved exclusively for individual psychotherapy sessions that last at least 53 minutes. If a session concludes at the 52-minute mark or earlier, the 90837 description no longer applies. In such instances, the clinician must downcode to 90834, which covers sessions between 38 and 52 minutes. Billing 90837 for shorter sessions constitutes a compliance error that can lead to claim denials or recoupment during 2026 financial audits. Documentation must clearly reflect the start and stop times to justify the use of this specific code.

The 90837 code is limited to individual treatment and is inappropriate for alternative modalities involving multiple participants. When a clinician conducts family psychotherapy, they must utilize specific codes such as 90847, which covers family therapy with the patient present, or 90846 for sessions without the patient. Similarly, group therapy sessions require the use of 90853 regardless of the time spent with the group. Attempting to use 90837 for these multi-person sessions is a procedural error that fails to accurately describe the service rendered to the insurance payer.

Clinicians should also distinguish standard 90837 billing from specialized behavioral health services that utilize different coding structures. While the majority of psychotherapy codes consist of five digits, certain psychotherapy CPT codes use alphanumeric formats consisting of four digits followed by one letter. These distinct formats are often designated for specific clinical assessments, monitoring, or interventions that fall outside the scope of a standard 60-minute individual talk therapy session. Identifying these variations prevents the billing department from defaulting to 90837 when a more specialized alphanumeric code is the correct choice.

Finally, 90837 is not applicable when the primary focus of the encounter is not psychotherapy. For instance, if a session is dedicated entirely to medication management without a significant, documented psychotherapy component, an Evaluation and Management (E/M) code is the appropriate selection. If psychotherapy is performed alongside medication management, 90837 may only be used as an add-on code if the psychotherapy portion itself meets the 53-minute requirement, which is uncommon in most clinical settings. Clinicians must verify the specific reimbursement rates and documentation requirements for these combinations on the payer's current fee schedule, as these details change frequently.

Automate time tracking within your EMR to ensure compliance

Relying on memory or manual wall clocks to determine session duration creates significant audit risk for the 90837 CPT code. Because this code requires a minimum of 53 minutes of face-to-face time, even minor discrepancies between the billed code and the documented session length can lead to payment recoupment. Practitioners often estimate session ends or round up from a 45-minute encounter, a practice that fails to meet the stringent time-based requirements of 2026 billing standards.

Transitioning to an Electronic Medical Record (EMR) with integrated time-tracking functionality removes the guesswork from the documentation process. These systems utilize built-in timers that trigger when a clinician opens a telehealth window or starts a progress note. By capturing the exact start and end times to the second, the software generates a precise record of the encounter duration. This automation ensures that the documentation reflects the actual time spent with the patient rather than an idealized schedule.

Automated timestamps serve as the primary defense during a clinical documentation review. When an EMR automatically logs that a session ran from 1:00 PM to 1:55 PM, it provides objective evidence that the 53-minute threshold was met. This level of precision eliminates the "rounding" errors common in paper-based or manual logs, where practitioners might habitually record one-hour blocks regardless of the actual interaction length. The system creates a verifiable audit trail that justifies the use of 90837 over 90834.

To implement this, clinicians should select an EMR vendor that specifically offers session-time triggers within their billing module. Many platforms now include dynamic clocks that alert the provider when the minimum threshold for 90837 is reached. Practitioners should confirm the specific features and reporting capabilities on the vendor’s current pricing or product page, as these functionalities vary between subscription tiers. Relying on these integrated tools allows the practitioner to focus on the clinical interaction while the software handles the compliance requirement for time-stamping.

Document medical necessity for extended psychotherapy sessions

Payers require explicit documentation to reimburse a 90837 claim. Clinical notes must record the exact start and stop times, or the total face-to-face time spent with the patient, to prove the session met the 53-minute threshold required for this code. Beyond time, the record must include the patient’s current mental status, the specific therapeutic interventions used, and the patient's response to the treatment. Documentation that fails to distinguish the activities of a 60-minute session from a standard 45-minute one often triggers denials or recoupment efforts during audits.

To establish medical necessity, providers must document why the patient’s condition required the extended duration. This involves detailing clinical complexities such as acute crisis management, the need for cognitive restructuring in complex trauma cases, or the implementation of multiple therapeutic modalities within a single visit. If the session involves a significant change in the treatment plan or the management of comorbid conditions, these factors must be explicitly stated. Simply checking a box for a 60-minute session without describing the increased intensity or complexity of the work performed is insufficient for most insurance carriers.

Practitioners can identify high-risk cases by reviewing their notes for generic or repetitive descriptions. A claim is considered high-risk if the documentation lacks a specific clinical justification for why the session could not have been completed within the 45-minute timeframe (CPT 90834). If every session for a particular patient is billed as 90837 without variations in the clinical narrative reflecting changing needs, payers may flag the account for a lack of individualization.

As of the most recent update on May 15, 2026, the emphasis remains on demonstrating the direct correlation between the extended time spent and the clinical benefit to the patient. Providers should treat the nine-minute read time of comprehensive billing guides as a baseline for understanding the nuances of these codes.

Frequently asked questions

What is the CPT code for a 50-minute individual psychotherapy session?

CPT 90834 is the correct code for a 50-minute individual psychotherapy session. This code applies to sessions lasting between 38 and 52 minutes. Ensure your documentation reflects the exact start and stop times to justify the selection of this mid-range duration code rather than the shorter 90832 or the 60-minute 90837.

Is cpt 90837 an add-on code?

No, CPT 90837 is a standalone primary procedure code, not an add-on code. You should report it independently for a 60-minute session that does not include an associated medical evaluation and management service. If you are providing psychotherapy alongside an E/M visit, you must instead use the appropriate E/M code plus the add-on code +90838.

What are the new CPT codes for telehealth in 2026?

Use the 98000–98015 series for synchronous audio-visual telehealth services in 2026. These codes were implemented to better reflect the complexity of remote care compared to traditional in-person visits. Verify specific payer requirements before billing, as some private insurers still mandate the use of standard psychotherapy codes combined with Place of Service (POS) codes 02 or 10.

What is the difference between CPT 97530 and 97110?

CPT 97530 covers therapeutic activities involving functional tasks like reaching or lifting, while 97110 covers therapeutic exercises focused on strength and range of motion. Choose 97530 when the intervention mimics real-world movements to improve a patient's overall functional performance. Select 97110 for targeted exercises aimed at specific physiological deficits, ensuring your clinical notes distinguish between functional activity and isolated exercise.

Choosing Between 90834 and 90837 for Your Next Session

Selecting the correct code requires more than just looking at the clock. While the 90837 cpt code description covers sessions 53 minutes and longer, applying it correctly involves verifying that the clinical depth of the session matches the extended duration. As you finalize your billing for 2026, run through this five-step checklist to ensure your selection is audit-proof and clinically justified.

1. Verify session duration, ensuring that the face-to-face time with the patient met the 53-minute minimum threshold required by current 2026 coding standards.
2. Assess clinical complexity, determining if the patient’s specific diagnosis and current symptom severity necessitate the additional time provided in a 60-minute psychotherapy session.
3. Consult payer policies, identifying any specific restrictions or pre-authorization mandates that your contracted insurance providers have established for the 90837 code.
4. Audit session documentation, confirming that your progress notes clearly articulate the specific therapeutic modalities and interventions utilized throughout the entire duration of the appointment.
5. Verify service eligibility, ensuring the session does not involve excluded services such as crisis intervention or evaluation and management components that require different billing designations.
