If you spotted CPT code 90834 on your Explanation of Benefits (EOB) or your therapist mentioned it before a session, you are probably wondering what it means. Billing codes can feel confusing, but this one is straightforward once you understand it. CPT code 90834 is the billing code used for a standard 45-minute individual psychotherapy session - one of the most commonly billed codes in outpatient mental health care. This article walks you through what this code covers, who can bill it, how insurance handles it, and what it might cost you.

Key Takeaways

• CPT code 90834 covers individual psychotherapy sessions lasting between 38 and 52 minutes, commonly referred to as a 45-minute session.

• The code is used by a wide range of licensed mental health providers - including LCSWs, LPCs, LMFTs, psychologists, and psychiatrists - in both in-person and telehealth settings.

• Most commercial insurance plans, Medicare, and Medicaid cover this code, though your specific out-of-pocket cost depends on your plan.

What Is CPT Code 90834?

CPT, which stands for Current Procedural Terminology, is a standardized system maintained by the American Medical Association (AMA) that healthcare providers use to describe services on insurance claims. Every therapy session you attend gets assigned one of these codes so insurers know what type of service was provided.

CPT code 90834 specifically refers to individual psychotherapy lasting approximately 45 minutes. The AMA defines the billable time range for this code as 38 to 52 minutes of face-to-face time with the patient. A session shorter than 38 minutes would not typically qualify for this code. The CMS describes the service covered by 90834 as insight-oriented, behavior modifying, supportive, and/or interactive psychotherapy.

This code is time-based, which means the session length - not the therapy type - determines whether 90834 is the right code to use. If the documented session time falls within the 38 to 52 minute window, 90834 is the appropriate choice.

Who Can Bill This Code?

A wide range of licensed mental health providers can bill CPT 90834. According to the APA and CMS, all mental health professionals - including psychologists, psychiatrists, nurses, and social workers - delivering psychotherapy services use the same applicable CPT codes when billing clients and filing health insurance claims with third-party payers, including Medicare, Medicaid, and private insurance carriers. Specific providers include:

• Licensed Clinical Social Workers (LCSWs)

• Licensed Professional Counselors (LPCs)

• Licensed Marriage and Family Therapists (LMFTs)

• Psychologists (PhD, PsyD)

• Psychiatrists (MD, DO)

• Psychiatric Nurse Practitioners and Clinical Nurse Specialists - when within their scope of practice and state license

Note that psychiatrists and other medical providers should only bill 90834 when psychotherapy is provided without evaluation and management (E/M) services. When psychotherapy occurs alongside medication management, different code combinations are required.

What Type of Therapy Does CPT Code 90834 Cover?

CPT 90834 covers individual psychotherapy - one-on-one talk therapy between a patient and a licensed provider. It does not apply to group therapy or family therapy sessions, which use separate codes.

The code does not specify a particular therapy modality, so it can be used for many evidence-based approaches, including:

• Cognitive Behavioral Therapy (CBT)

• Dialectical Behavior Therapy (DBT)

• Psychodynamic therapy

• Acceptance and Commitment Therapy (ACT)

• Supportive therapy

• Other individual psychotherapy approaches

There are some situations where 90834 is not appropriate. According to CMS billing guidance, this code should not be used for sessions primarily involving non-psychotherapy services, such as teaching grooming or daily living skills, recreational therapy, or case management. It is also not the appropriate code for clients with intellectual disabilities or severe dementia, where other codes apply.

Does 90834 Cover Telehealth?

Yes. The CPT code itself remains the same whether a session is in-person or via video. A 45-minute telehealth psychotherapy session is still billed as 90834 - the difference is that providers must add a telehealth modifier to indicate the session was conducted remotely. The most common modifier is 95, used for synchronous (real-time audio and video) telehealth services. Some payers, particularly certain Medicaid plans, use Modifier GT instead. Providers should verify which modifier each payer requires.

Medicare's telehealth flexibilities for behavioral health are now permanent, meaning telehealth sessions are reimbursed at the same rate as in-person visits for these services. As of 2025, 44 states and the District of Columbia have laws addressing telehealth reimbursement for private payers, with many requiring payment parity between telehealth and in-person services. You should still confirm coverage details directly with your insurer, as policies vary.

Does Insurance Cover CPT Code 90834?

For most people, yes - but the details depend on your specific plan.

Commercial Insurance

Most commercial health insurance plans are required to cover mental health services under the Mental Health Parity and Addiction Equity Act (MHPAEA), a federal law requiring insurers to cover mental health and substance use disorder benefits at the same level as medical and surgical benefits. Whether a specific session billed under 90834 is covered depends on:

• Whether your provider is in-network or out-of-network

• Your plan's deductible, copay, or coinsurance structure

• Whether prior authorization is required

Medicare

Medicare Part B covers outpatient mental health services, including individual psychotherapy. According to CMS, Medicare continues to reimburse telehealth services at the in-person rate for behavioral health. Reimbursement rates vary by provider credential: psychologists are typically reimbursed at 100% of the Medicare Physician Fee Schedule rate, while LCSWs are reimbursed at 75% of the psychologist rate. Starting in January 2024, LMFTs and Licensed Mental Health Counselors (LMHCs) became eligible to bill Medicare independently, also at 75% of the psychologist rate - a significant expansion of coverage access.

Medicaid

Medicaid coverage for CPT 90834 varies by state, but most state programs cover individual outpatient psychotherapy. A 2025 study published in Health Affairs found that between 2019–21 and 2024, 38 states increased their Medicaid reimbursement rates for CPT 90834 by an average of 24.5 percent. On average, Medicaid pays approximately 74 percent of Medicare rates for psychological services.

How to Verify Your Benefits

Before your first session, call the member services number on the back of your insurance card and ask:

• Is CPT code 90834 covered under my plan?

• Is my provider in-network?

• Do I need prior authorization for ongoing therapy?

• What is my copay or coinsurance for outpatient mental health sessions?

How Much Does a Session Billed Under 90834 Cost?

Cost depends on your insurance coverage, your provider's credentials, and your location.

For Medicare specifically, published reimbursement rates for CPT 90834 were $101.51 for both 2024 and 2025, and $99.97 in 2023. These are the total Medicare-approved amounts - what you actually pay out of pocket depends on whether you have met your Part B deductible and whether you have supplemental coverage.

Because rates vary by region, payer, and provider type, the most reliable way to find your specific cost is to check directly with your insurer before your appointment.

Sliding Scale and Lower-Cost Options

If cost is a barrier, many therapists offer a sliding scale fee that adjusts based on income. Community mental health centers also often provide therapy at reduced rates. SAMHSA's treatment locator at findtreatment.gov can help you find lower-cost options in your area.

CPT Code 90834 vs. Related Individual Therapy Codes

You may see different therapy codes on your insurance paperwork. Here is how 90834 fits within the individual psychotherapy code family:

The code used depends entirely on the documented face-to-face time of the session - not how long you were in the office or waiting. If your session ran closer to 30 minutes, you may see 90832. If it ran a full hour or more, you may see 90837. Seeing a different code than expected on your EOB does not mean something went wrong - it simply reflects the actual length of your session.

Note that 90834 reimbursement typically runs 70 to 80 percent of the rate for a 60-minute session (90837).

What to Expect During a Session Billed as CPT 90834

A session billed under 90834 is a standard one-on-one meeting between you and your licensed therapist lasting between 38 and 52 minutes. Most sessions follow a general structure:

• Opening: Your therapist typically follows up on the previous session, checks in on your week, and sets the focus for today.

• Core work: The majority of time is spent on therapeutic work - exploring thoughts, emotions, behaviors, or experiences depending on your goals and the approach being used.

• Wrap-up: Your therapist may summarize key insights, discuss any next steps, and confirm your next appointment.

The number of sessions recommended varies widely based on your individual needs and treatment goals. Your therapist will work with you to determine an appropriate frequency and duration for your care.

Streamlining Documentation for 90834 Sessions

After every session, therapists are required to write a progress note documenting what occurred, the interventions used, and the time spent - all of which directly supports the billing code selected. For a 45-minute session billed under 90834, that documentation needs to reflect the session duration, the therapeutic content, and the client's progress.

Can a psychiatric nurse practitioner bill CPT 90834?

In many cases, yes - when it falls within their scope of practice and state licensure. CMS billing guidance notes that this code can be used by nurse practitioners and clinical nurse specialists when services are performed within their state license and clinical practice. Payer-specific credentialing rules may apply, so confirm with both the provider and the insurer.

Why does my EOB show 90834 instead of a different code?

Code selection is based on the actual face-to-face time of your therapy session. If your session was between 38 and 52 minutes, your therapist is required to use 90834. If it was shorter or longer, a different code would apply. This is standard billing practice and does not indicate an error.

How do I find a therapist who accepts my insurance for 90834 sessions?

Call your insurance company's member services line and ask for a list of in-network mental health providers. You can also use your insurer's online provider directory. Ask specifically about coverage for outpatient individual therapy to confirm that sessions billed under 90834 are included in your plan.

Does the type of therapy affect whether 90834 is covered?

Generally, no. CPT 90834 is defined by session length and format - not by therapeutic modality. Whether your therapist uses CBT, DBT, psychodynamic therapy, or another evidence-based approach, the billing code is the same as long as the documented session time falls within the 38 to 52 minute range.

Conclusion

CPT code 90834 is one of the most widely used billing codes in outpatient mental health. It covers a standard 45-minute individual psychotherapy session and applies across a broad range of licensed providers, settings, and therapeutic approaches.
