# CPT 90868

> Not at a published national rate. CPT 90868 carries status C (carrier-priced) in the Q1 2020 release. Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. Treat the blank amount as unpriced, not as $0.

## What it is

One treatment session of transcranial magnetic stimulation (TMS), a non-invasive therapy in which a magnetic coil held against the scalp induces electrical activity in a targeted area of the brain. This code covers the routine sessions that follow the initial visit, where the settings and coil position have already been established. The first session in a course is reported differently because it includes mapping the brain target and finding the patient's stimulation threshold; a separate code covers later sessions where that threshold has to be re-measured. A full course typically runs daily over several weeks, so most sessions in a course fall under this code.
