Official Description

Therapeutic repetitive transcranial magnetic stimulation (TMS) treatment; subsequent delivery and management, per session

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive therapeutic procedure primarily utilized for the treatment of depression in patients who have not responded to other treatment options. This innovative technique may also be applied to address various other mental health conditions, including anxiety disorders, obsessive-compulsive disorder (OCD), auditory hallucinations, and migraines. The underlying principle of rTMS involves the modulation of brain activity, particularly in areas that may be overactive or underactive in relation to specific disorders. For instance, individuals suffering from depression often exhibit reduced activity in the left prefrontal cortex, a region associated with mood regulation. The procedure employs magnetic fields to stimulate nerve cells in targeted regions of the brain, effectively altering the brain's biochemistry and influencing the firing patterns of neurons. This stimulation is achieved through the use of a large electromagnetic coil, which is positioned against the scalp over the designated area of the brain. When activated, the coil generates painless electric currents that stimulate the nerve cells, resulting in a tapping or clicking sound and a corresponding tapping sensation on the head. In the initial planning and management session, as described in CPT® Code 90867, the physician identifies the optimal sites for magnet placement, determines the ideal rate of stimulating pulses, and calculates the appropriate dose of magnetic energy required for effective treatment. This mapping process involves adjusting the position of the electromagnetic coil and varying the pulse rate until the motor threshold is established, which is the point at which muscle twitching occurs. Once this threshold is determined, the physician can calculate the optimal dose for subsequent treatments. CPT® Code 90868 is specifically designated for each subsequent delivery and management session where the motor threshold does not require adjustment. During these follow-up sessions, the magnets are reapplied to the head, and the previously established optimal level and duration of stimulation are administered. In cases where re-determination of the motor threshold is necessary, CPT® Code 90869 is utilized. This structured approach ensures that the treatment is tailored to the individual needs of the patient, enhancing the overall effectiveness of rTMS therapy.

1. Indications

The therapeutic repetitive transcranial magnetic stimulation (TMS) treatment, as described by CPT® Code 90868, is indicated for the following conditions:

  • Depression - Primarily used for individuals who have not responded to other treatment modalities.
  • Anxiety - May be utilized as a treatment option for patients experiencing anxiety disorders.
  • Obsessive-Compulsive Disorder (OCD) - Can be applied to help manage symptoms associated with OCD.
  • Auditory Hallucinations - Used in the treatment of patients experiencing auditory hallucinations.
  • Migraines - May also serve as a therapeutic option for individuals suffering from migraines.

2. Procedure

The procedure for therapeutic repetitive transcranial magnetic stimulation (TMS) involves several key steps, which are outlined as follows:

  • Initial Planning and Mapping - In the initial session, the physician conducts a thorough assessment to determine the best sites on the forehead for the placement of the electromagnetic coil. This involves identifying the optimal rate of stimulating pulses and the appropriate dose of magnetic energy required for effective treatment. The physician moves the coil around the scalp to find the most effective location for stimulation.
  • Determining Motor Threshold - The physician increases the energy delivered through the coil until muscle twitching is observed, which helps establish the motor threshold. This threshold is critical for determining the optimal dose of stimulation for subsequent sessions.
  • Subsequent Treatment Sessions - For each subsequent delivery and management session, as indicated by CPT® Code 90868, the physician repositions the magnets on the head and administers the previously determined optimal level and duration of stimulation. This process is repeated for each session, ensuring that the treatment remains consistent and effective.
  • Adjustment of Treatment - If necessary, the physician may adjust the stimulation parameters based on the patient's response to treatment and any side effects experienced. This ensures that the therapy is tailored to the individual needs of the patient.

3. Post-Procedure

After the completion of each rTMS session, patients may experience mild side effects, such as headache or scalp discomfort, which typically resolve shortly after the procedure. It is important for patients to follow any post-procedure care instructions provided by the physician. Continuous monitoring of the patient's response to treatment is essential, and adjustments to the stimulation parameters may be made in subsequent sessions if required. The overall recovery process is generally quick, allowing patients to resume their daily activities shortly after each session. Regular follow-up appointments are necessary to assess the effectiveness of the treatment and make any necessary modifications to the therapy plan.
