CPT Code 90867 represents the initial administration of Transcranial Magnetic Stimulation (TMS), a specialized psychiatric treatment gaining recognition for its effectiveness in treating major depressive disorder and other treatment-resistant conditions. This code is essential for proper billing and reimbursement of the first session in a series of TMS treatments.

This guide provides healthcare professionals with critical information about implementing, billing, and meeting regulatory requirements for CPT code 90867. Whether you're a psychiatrist, billing specialist, or practice administrator, you'll find valuable insights to effectively navigate TMS therapy billing.


What Is CPT Code 90867?

CPT Code 90867 specifically describes the "Therapeutic repetitive transcranial magnetic stimulation treatment; initial, including cortical mapping, motor threshold determination, delivery and management." It represents the first session in a series of TMS treatments, which encompasses several critical components that distinguish it from subsequent treatment sessions.

This initial TMS session is more comprehensive than follow-up treatments, as it includes several essential procedures:

Cortical Mapping

The process of identifying the precise location on the skull where the magnetic coil should be positioned to target the appropriate brain region.

Motor Threshold Determination

Establishing the minimum intensity needed to elicit a motor response, which serves as a baseline for calibrating treatment intensity.

Initial Delivery

The first administration of the magnetic pulses according to the prescribed protocol.

Treatment Planning and Management

Documentation of the treatment parameters and the patient's response.

Unlike subsequent sessions (billed under CPT code 90868), this initial session typically requires more time and clinical expertise to properly establish treatment parameters that will guide the entire course of therapy.


Who Can Bill CPT Code 90867?

The ability to bill for TMS therapy using CPT code 90867 is restricted to specific healthcare providers who meet the necessary qualifications and practice in appropriate clinical settings. Check with your insurance provider to confirm coverage and eligibility, as CPT code 90867 for TMS therapy can only be billed by specific qualified healthcare providers practicing in approved clinical settings.

Frequently Asked Questions

Can CPT code 90867 be billed more than once per treatment course?

Generally, CPT code 90867 should only be billed once at the beginning of a treatment course, as it represents the initial session, including mapping and threshold determination. However, if a significant clinical change occurs requiring complete re-mapping and new threshold determination, a second instance may be justified with appropriate documentation. Some payers may require a modifier in these circumstances.

Does CPT code 90867 include the technical component of TMS delivery?

Yes, CPT code 90867 is a comprehensive code that includes both the professional component (physician work) and the technical component (equipment, facility, and technician costs). It should not be billed with separate technical component codes or modifiers unless specifically required by certain payers.

What diagnosis codes support medical necessity for CPT code 90867?

The most commonly accepted diagnosis code is F33.2 (Major depressive disorder, recurrent, severe without psychotic features), though other depression codes may be accepted depending on the payer. Some payers may accept F32.2 (Major depressive disorder, single episode, severe without psychotic features). It's essential to check each insurer's policy for covered diagnoses. Currently, most payers only cover TMS for depression, not for other conditions like OCD or anxiety disorders.

How long must a patient fail medication trials before TMS therapy is considered medically necessary?

Most insurance policies require documentation of failure to achieve satisfactory improvement after 4-6 weeks of treatment at adequate doses for at least 2-4 antidepressant medications from at least 2 different classes. The exact requirements vary by payer, with some requiring failure of as many as 4 medication trials plus psychotherapy.

Can non-physician providers bill for CPT code 90867?

In most cases, the initial TMS session must either be performed by or directly supervised by a physician (typically a psychiatrist or neurologist).

While subsequent sessions may have more flexible supervision requirements, the initial mapping and threshold determination generally require physician involvement. Some payers may allow properly trained and certified nurse practitioners or physician assistants to bill for this service under certain circumstances.


Bottom Line

CPT code 90867 represents a critical component in the delivery and reimbursement of Transcranial Magnetic Stimulation therapy for treatment-resistant depression. As an innovative treatment modality that continues to gain clinical acceptance and insurance coverage, understanding the proper application of this code is essential for healthcare providers offering TMS services.

Successful billing for TMS therapy requires attention to detail in documentation, thorough knowledge of payer requirements, and strategic approaches to authorization and claims submission. By implementing the best practices outlined in this guide, providers can minimize claim denials, optimize reimbursement, and ultimately improve patient access to this effective treatment option.

As TMS therapy continues to evolve, with expanding indications and technological innovations, staying current with coding and billing requirements will remain an important priority for psychiatric practices and other facilities offering brain stimulation therapies.
