Official Description

Electroconvulsive therapy (includes necessary monitoring)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Electroconvulsive therapy (ECT) is a medical procedure that involves the application of electric currents to the brain to induce a controlled seizure. This therapeutic approach is primarily utilized to treat severe mental health conditions, including major depressive disorder, schizophrenia, mania, and catatonia. The underlying principle of ECT is to facilitate chemical changes in the brain that can alleviate the symptoms associated with these mental illnesses. During the procedure, the patient is placed under general anesthesia to ensure comfort and safety. Electrode pads are strategically positioned on the patient's head, either on one side (unilateral) or both sides (bilateral), to deliver the electric currents effectively. To prevent muscle paralysis during the seizure, a muscle relaxant is administered intravenously, and a blood pressure cuff is applied to the ankle or forearm. This cuff serves to monitor muscle activity and ensure that the seizure is occurring as intended. The physician carefully controls the amount of current delivered through the electrodes, aiming to produce a seizure lasting between 30 to 60 seconds. Throughout the procedure, the physician monitors the patient's response by observing movements in the cuffed extremity and analyzing the increased brain activity displayed on an electroencephalogram (EEG). Many patients experience significant improvement in their symptoms after just two or three ECT sessions, and the efficacy of the treatment often increases with multiple sessions.

1. Indications

Electroconvulsive therapy (ECT) is indicated for several severe mental health conditions. The following are the primary indications for this procedure:

  • Severe Depression ECT is often utilized for patients suffering from major depressive disorder, particularly when other treatments have failed or when rapid response is necessary.
  • Schizophrenia This therapy may be indicated for individuals experiencing severe symptoms of schizophrenia that do not respond adequately to medication.
  • Mania ECT can be effective in treating manic episodes associated with bipolar disorder, especially when the patient is at risk of harm or when rapid stabilization is required.
  • Catatonia Patients exhibiting catatonic symptoms may benefit from ECT, as it can help alleviate the severe motor and behavioral disturbances associated with this condition.

2. Procedure

The procedure for electroconvulsive therapy (ECT) involves several critical steps to ensure patient safety and the effectiveness of the treatment. The following outlines the procedural steps:

  • Preparation Prior to the procedure, the patient is evaluated to confirm the appropriateness of ECT. This includes a thorough medical history and physical examination. The patient is then informed about the procedure, and consent is obtained.
  • Anesthesia Administration The patient is placed under general anesthesia to ensure they are unconscious and pain-free during the procedure. An intravenous line is established for the administration of anesthetic agents and muscle relaxants.
  • Electrode Placement Electrode pads are positioned on the patient's head. The placement can be unilateral (one side) or bilateral (both sides), depending on the treatment plan determined by the physician.
  • Seizure Induction Once the patient is adequately anesthetized, a blood pressure cuff is applied to the ankle or forearm to monitor muscle activity. The physician then delivers a small amount of electric current through the electrodes, inducing a seizure that typically lasts between 30 to 60 seconds.
  • Monitoring During the seizure, the physician closely monitors the patient's response by observing movements in the cuffed hand or foot and analyzing the electroencephalogram (EEG) for increased brain activity.
  • Recovery After the seizure, the patient is taken to a recovery area where they are monitored until the effects of anesthesia wear off. The medical team ensures the patient is stable before discharge.

3. Post-Procedure

Post-procedure care for patients who have undergone electroconvulsive therapy (ECT) includes monitoring for any immediate side effects, such as confusion or temporary memory loss, which are common after the treatment. Patients are typically observed in a recovery area until they are fully awake and stable. It is essential to provide reassurance and support during this time, as patients may feel disoriented. Follow-up appointments are scheduled to assess the effectiveness of the treatment and to determine if additional ECT sessions are necessary. Patients are advised to have a responsible adult accompany them home due to the lingering effects of anesthesia. Ongoing evaluation of the patient's mental health status is crucial to ensure that the treatment goals are being met and to make any necessary adjustments to the treatment plan.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
GW Service not related to the hospice patient's terminal condition
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
XP Separate practitioner, a service that is distinct because it was performed by a different practitioner
GZ Item or service expected to be denied as not reasonable and necessary
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
