If you have seen CPT code 90792 on a bill or an insurance form, you may be wondering what it actually means. This code covers a psychiatric diagnostic evaluation with medical services - and understanding it can help you prepare for your appointment, know what to expect, and make sense of your coverage.

Key Takeaways

• CPT code 90792 is used when a qualified prescribing provider - such as a psychiatrist or psychiatric nurse practitioner - performs an initial psychiatric evaluation that includes a medical component, such as reviewing medications or assessing the need for prescriptions.

• It is billed only by providers who are licensed to deliver medical services. Therapists, counselors, and social workers use a different code and cannot bill 90792.

• Most commercial insurance plans, Medicare, and Medicaid managed care plans cover this evaluation when it is medically necessary, though coverage details, prior authorization requirements, and cost-sharing vary by plan.

What Is CPT Code 90792?

CPT code 90792 is a billing code for a psychiatric diagnostic evaluation with medical services. According to the American Medical Association, it describes an integrated biopsychosocial and medical assessment that includes history, mental status, other physical examination elements as indicated, and recommendations.

In plain terms: it is a comprehensive first appointment with a prescribing mental health provider - someone who can both evaluate your mental health and address medical factors, such as whether medication might be appropriate for your care.

This is an initial evaluation code. It is not used for ongoing therapy sessions or routine follow-up visits.

Who Uses This Code?

CPT code 90792 can only be billed by providers who are qualified and licensed to deliver medical services. This typically includes:

• Psychiatrists (MD or DO)

• Psychiatric mental health nurse practitioners (PMHNP)

• Physicians with psychiatric training

• Clinical nurse specialists with the appropriate licensure, depending on state regulations

Therapists, licensed counselors (LPC, LMFT), licensed clinical social workers (LCSW), and psychologists who do not hold prescriptive authority do not use this code. They bill a separate evaluation code that does not include medical services.

What Does the Evaluation Cover?

A 90792 evaluation is a thorough initial assessment - not a brief check-in. The provider is building a full picture of your mental and physical health before making any clinical recommendations.

During the evaluation, the provider will typically cover:

• The presenting concern - what brought you in, how long symptoms have been happening, and how they affect your daily life

• Psychiatric history - prior diagnoses, hospitalizations, or past treatment

• Medical history - physical health conditions and any factors that may influence mental health or medication choices

• Medication review - current and past psychiatric medications, including what has or has not worked

• Family history - mental health or medical conditions in close family members

• Social history - living situation, relationships, work or school, and substance use

• Mental status examination - a clinical observation of mood, thought patterns, speech, and overall presentation

The goal is to understand the complete picture so the provider can make safe, informed recommendations. This may include whether medication could be appropriate - but a 90792 evaluation does not automatically mean medication will be prescribed. The medical component simply means the provider is qualified to consider it as part of your care.

How Long Does It Take?

A 90792 evaluation typically involves 60 to 120 minutes of provider time, though this can vary based on clinical complexity.

How Often Can It Be Billed?

Most insurance plans, including Medicare, limit 90792 to once per year per provider-patient relationship. According to the American Psychiatric Association's CPT guidance for psychiatrists, Medicare will pay for only one 90792 per year for most patients unless medical necessity for an additional evaluation is clearly documented. It may be billed on subsequent days when there is medical necessity for an extended evaluation - for example, when evaluating a child that requires the provider to meet with both the child and the parents separately and together.

Is It Available via Telehealth?

Yes. CPT code 90792 can be billed for telehealth evaluations conducted via a live, HIPAA-compliant video platform. When billed as a telehealth service, providers typically append modifier 95 to indicate the service was rendered via real-time interactive audio and video. Because the scope of a telehealth evaluation is limited - a physical exam cannot be performed remotely, for example - providers and patients should confirm telehealth coverage and any applicable requirements with their specific payer before the appointment.

Does Insurance Cover CPT Code 90792?

In most cases, yes - insurance does cover psychiatric evaluations billed under 90792 when they are deemed medically necessary. Coverage details depend on your specific plan, your provider's network status, and whether prior authorization is required.

Commercial Insurance

Most commercial health insurance plans cover 90792 evaluations under their mental health benefits. The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) is a federal law that generally prevents group health plans and health insurance issuers from imposing less favorable benefit limitations on mental health services than on medical or surgical benefits. This means that copays, visit limits, and prior authorization requirements for psychiatric evaluations generally cannot be more restrictive than those for comparable medical visits - for plans subject to the law.

It is worth noting that MHPAEA does not require a plan to cover mental health benefits in the first place. However, the Affordable Care Act requires coverage of mental health services as an essential health benefit in non-grandfathered individual and small group plans.

Medicare

Medicare Part B covers psychiatric evaluations billed under 90792 when the service is medically necessary and performed by a Medicare-enrolled provider. Medicare typically allows one 90792 per year for outpatient patients, though additional evaluations may be covered when medical necessity is clearly documented. For specific cost-sharing details under your Medicare plan, contact Medicare directly or visit medicare.gov.

Medicaid

Federal law requires Medicaid and CHIP programs to comply with mental health parity requirements. However, Medicaid coverage rules, reimbursement rates, and documentation requirements vary significantly by state. Patients covered by Medicaid should confirm coverage and any authorization requirements directly with their state program or the provider's billing office.

Prior Authorization

Some insurance plans require prior authorization before a 90792 evaluation is covered. Calling your insurance provider before your appointment to ask whether this applies to your plan can help you avoid unexpected costs or claim denials.

How to Verify Your Benefits

Before your evaluation, a few steps can help you understand what to expect:

• Call the member services number on the back of your insurance card and ask whether CPT code 90792 is covered under your plan

• Ask whether the provider you are seeing is in-network

• Ask whether prior authorization is required, and whether the provider's office handles that process

• Request an estimate of your expected out-of-pocket cost

How Much Does a 90792 Evaluation Cost?

The cost of a 90792 evaluation varies depending on your location, the type of provider, and whether you are using insurance. For patients covered by Medicare, one published estimate places Medicare reimbursement for 90792 in the range of $150 to $190, though rates vary by geographic area and are updated annually through the CMS Physician Fee Schedule. For the most current Medicare rates in your area, the CMS Physician Fee Schedule Look-up Tool is the most reliable source.

Without insurance, costs will reflect the provider's individual fee schedule and can vary widely. If cost is a concern, several options may help:

• Community mental health centers often provide services on a sliding-scale fee based on income

• Federally Qualified Health Centers (FQHCs) offer psychiatric services at reduced rates for qualifying patients

• Teaching hospitals and university clinics may offer evaluations at lower cost

• Telehealth options have expanded access and may reduce some overhead, though rates vary by provider and payer

CPT Code 90792 vs. CPT Code 90791: What Is the Difference?

You may also see CPT code 90791 on bills or insurance documents. These two codes are closely related but cover different types of evaluations.

The key difference is the medical services component. If your evaluation is with a prescribing provider who is also assessing whether medication may be part of your treatment, 90792 is the appropriate code. Seeing one code versus the other on your Explanation of Benefits is not a cause for concern - it simply reflects the type of provider you saw.

What to Expect During Your Evaluation

Many people feel nervous before a psychiatric evaluation, especially if it is their first one. Knowing what to expect can help.

The appointment will often begin with the provider reviewing paperwork you completed in advance, including questions about your symptoms, medical history, and current medications. The provider will then ask you questions directly. Some may feel personal, but the purpose is always to understand your situation more fully, not to judge you.

You do not need to have everything figured out before you arrive. Many patients come in unsure of what is wrong or how to explain what they have been experiencing. The provider's job is to help make sense of that together with you.

At the end of the evaluation, the provider will typically share their clinical impressions. This may include a working diagnosis, a recommendation for therapy, a discussion of whether medication might be helpful, or a referral to another specialist. In some cases, the provider may want to gather more information before making final recommendations.

Frequently Asked Questions

Is CPT code 90792 covered by Medicaid?

How do I find a provider who accepts my insurance for a 90792 evaluation?
