What 90870 covers

Electroconvulsive therapy (ECT) is a treatment session in which a clinician applies a brief electrical stimulus through scalp electrodes to produce a controlled seizure. A psychiatrist typically directs or performs the treatment for severe mood disorders, catatonia, or other psychiatric conditions when ECT is clinically selected. It is commonly delivered in a hospital or ambulatory procedure setting with anesthesia, muscle relaxation, and physiologic monitoring; anesthesia services are generally furnished by a separate anesthesia professional.

Report 90870 for the ECT treatment itself, not for psychotherapy or an entire course of treatment. The record should identify the treatment session and support that ECT was performed, including the clinical indication and procedural details. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. An assistant-at-surgery service is payable only when medical necessity is documented; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90870 billing questions

How does 90870 differ from transcranial magnetic stimulation?

90870 reports ECT, which uses electrical stimulation to induce a therapeutic seizure under anesthesia. Code 90868 reports a transcranial magnetic stimulation treatment session.

Can anesthesia be reported separately?

An anesthesia professional may report 00104 for anesthesia furnished for ECT when the service is performed and documented. Code 90870 reports the ECT treatment itself.

Does 90870 cover an entire course of ECT?

No. Report the code for each ECT treatment session performed, rather than for the overall course or treatment plan.

Should modifier 50 be appended for bilateral electrode placement?

No. CMS identifies bilateral adjustment as inappropriate for 90870, regardless of electrode placement.

When can an assistant-at-surgery service be paid?

CMS permits assistant-at-surgery payment only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
