Psychotherapy billing is essential to the financial health of mental health practices, enabling practitioners to secure proper reimbursement for services. Accurate Psychotherapy Billing CPT Codes helps avoid denials and ensures that providers are compensated fairly for their time and expertise.
CPT codes 90837 and 90834 are the two most commonly used codes for individual psychotherapy sessions. They help insurers categorize services and determine reimbursement amounts. Each code represents a specific session length, with 90834 used for sessions lasting 45 minutes and 90837 for sessions lasting 60 minutes.
Knowing the difference between CPT codes 90837 and 90834 is essential for maximizing reimbursement and avoiding claim rejections. Proper coding can also streamline the billing process, improve revenue cycle efficiency, and reduce claim resubmissions.
What is CPT Code 90834?
- Definition and Description
CPT code 90834 represents a psychotherapy session lasting approximately 45 minutes. It is often referred to as a “standard” therapy session and is commonly used for patients requiring ongoing therapy without needing extended session time. - Typical Scenarios for Using 90834
This code is suitable for patients who need consistent therapy but do not require the longer 60-minute session that 90837 entails. Providers typically use 90834 for regular sessions addressing ongoing issues without an immediate crisis or intensive therapeutic need. - Reimbursement Rates for 90834
Reimbursement rates for 90834 can vary based on the payer, location, and provider credentials. Generally, 90834 has a lower reimbursement rate than 90837 due to the shorter session length. - When to Choose 90834 Over Other Codes
Clinicians should select 90834 when session time consistently falls within 38-52 minutes. Shorter or longer sessions would necessitate different codes to avoid underbilling or overbilling.
What is CPT Code 90837?
- Definition and Description
CPT code 90837 is used for a psychotherapy session lasting approximately 60 minutes. This code is for more intensive sessions and is often used in situations where deeper exploration and treatment are necessary, such as during crisis intervention. - Typical Scenarios for Using 90837
Use 90837 when a patient’s needs demand extended time, such as managing complex issues, trauma therapy, or when multiple therapeutic interventions are required within a session. - Reimbursement Rates for 90837
Reimbursement for 90837 is higher than 90834 due to the longer session duration. This code’s rate may vary by payer, geographic region, and provider qualification, but it generally reflects the increased therapeutic commitment. - When to Choose 90837 Over Other Codes
Providers should use 90837 if the session consistently lasts 53 minutes or longer. This code is optimal for more complex or in-depth therapy sessions that cannot be adequately conducted within a 45-minute timeframe.
Key Differences Between CPT Codes 90834 and 90837
- Session Length Requirements
- 90834: For sessions lasting 38-52 minutes.
- 90837: For sessions lasting 53 minutes or longer.
- Reimbursement Implications
Due to the longer session length, 90837 generally has a higher reimbursement rate than 90834. However, using 90837 improperly can lead to denials, as some payers may scrutinize frequent 60-minute sessions. - Appropriateness Based on Patient Need
90834 is more suitable for regular, ongoing sessions, while 90837 is intended for more complex or intensive therapeutic needs. Providers should select the code that most accurately reflects the patient’s treatment plan and session requirements.
Documentation Requirements for CPT Codes 90834 and 90837
- Session Start and End Times
Documenting exact start and end times is essential for both 90834 and 90837 to validate that the session met the time requirements. - Clinical Notes and Progress
Clinical notes should outline the patient’s symptoms, therapeutic interventions used, and progress. Each session should provide detailed documentation to justify the need for therapy. - Treatment Goals and Outcomes
Clearly stated treatment goals and measurable outcomes provide necessary support for the session’s billed code, whether 90834 or 90837. - Importance of Medical Necessity Documentation
Insurers often review documentation to assess the necessity of extended sessions. Accurate records help defend against potential audits or denials, especially when billing 90837 for frequent 60-minute sessions.
Understanding Insurance Policies for 90834 and 90837
- Differences in Reimbursement Policies Among Payers
Each insurer has unique policies and reimbursement rates for 90834 and 90837. Some may limit the number of 90837 sessions they’ll approve, while others may require prior authorization for longer sessions. - Preauthorization Requirements
Some insurance plans mandate preauthorization for extended sessions billed with 90837. Providers should check payer guidelines to confirm if authorization is necessary. - Limitations on Frequency of 90837 Sessions
Certain payers limit how often 90837 can be billed within a given time frame. Understanding these limitations can help providers avoid denials and plan treatment schedules accordingly.
Common Denial Reasons for 90834 and 90837
- Time Documentation Issues
Inadequate documentation of session length is a frequent cause of denials for both codes. Insurers require proof that the session met the time threshold for the billed code. - Medical Necessity Denials
When insurers believe that a 60-minute session was unnecessary, they may deny the claim for 90837. Clear documentation of medical necessity is crucial. - Frequency of Extended Sessions (90837)
Excessive billing of 90837 can lead to denials or payer audits, especially if used for every session. To avoid this, providers should assess whether each patient requires a 60-minute session. - Incorrect Use of CPT Codes
Using 90837 when the session does not meet the minimum 53-minute requirement can lead to denials. Conversely, underbilling by using 90834 for a 60-minute session can result in lost revenue.
Tips for Avoiding Denials for CPT Codes 90834 and 90837
- Accurate Time Documentation
Always record session start and end times in patient records to substantiate the billing code. - Consistency with Payer Policies
Review payer policies on session frequency, duration, and authorization requirements to ensure compliance with insurer guidelines. - Detailed Session Notes
Document the interventions used, patient responses, and specific reasons for requiring an extended session if billing 90837. This information helps justify the necessity of longer sessions to insurers. - Use of Electronic Health Records (EHRs)
EHRs often streamline documentation by including templates that ensure accurate records, including start and end times, intervention details, and treatment progress.

CPT code 90834 is for a 45-minute individual psychotherapy session (typically lasting between 38-52 minutes), while CPT code 90837 is for a 60-minute session (lasting 53 minutes or longer). The main difference is the session length and intensity, with 90837 generally requiring a higher level of therapeutic intervention.
How long should a session be to bill for 90834 versus 90837?
To bill for 90834, the session should last at least 38 minutes but not exceed 52 minutes. For 90837, the session must last a minimum of 53 minutes. These time guidelines are essential for accurate billing and avoiding denials.
Can I use 90837 for every therapy session?
While 90837 is suitable for sessions requiring extended time, it’s best used when clinically justified, as insurers may scrutinize its frequent use. Repeated billing of 90837 could lead to denials or payer audits unless the extended time is well documented as medically necessary.
Do insurance companies pay more for 90837 than 90834?
Yes, since 90837 represents a longer session, it generally has a higher reimbursement rate than 90834. However, each payer sets different rates, and reimbursement can vary based on location, provider credentials, and contract terms.
What should I document when billing for 90837?
When billing for 90837, include detailed notes on the session’s duration, specific therapeutic interventions used, the patient’s responses, and why the extended time was necessary. Documentation is essential to support the medical necessity of a longer session.
Can I switch between 90834 and 90837 for the same patient?
Yes, you can switch between 90834 and 90837 depending on each session’s needs. For example, if a patient requires more in-depth intervention one week, you might bill 90837, and if the next session is shorter, you might use 90834. Choose the code that best represents the session’s length and therapeutic need.
Are preauthorizations required for 90837?
Some insurance plans require preauthorization for 90837, especially for recurring 60-minute sessions. Always check with the specific payer to determine if preauthorization is necessary to avoid claim denials.
Why do claims for 90837 sometimes get denied?
Common reasons for 90837 denials include lack of medical necessity, insufficient documentation, exceeding payer limitations on 60-minute sessions, or not meeting the minimum time threshold of 53 minutes. Reviewing and following payer guidelines closely can help prevent denials.
Is it necessary to document start and end times for each session?
Yes, documenting exact start and end times can help substantiate the session length, especially for 90837. This helps avoid billing discrepancies and provides clear evidence that the session met the time requirement.
Can billing 90837 too frequently trigger an audit?
Yes, frequent use of 90837 may trigger an audit, as insurers might view it as an indication of potentially unnecessary extended sessions. To avoid this, ensure that 90837 is used only when clinically appropriate and that documentation supports the need for a 60-minute session.
