Billing and Coding: Transcranial Magnetic Stimulation (TMS)

TMS is covered when delivered with an FDA‑approved device for treatment of depressive disorders and must be documented in the medical record with validated depression rating scales. Coverage allows an initial course of up to 20 visits over 4 weeks plus up to 5 taper visits, with a possible 2‑week extension (+10 visits) and 6 taper visits if the patient achieves ≥25% improvement; treatments beyond these parameters are not covered unless prior response met >50% improvement criteria and retreatment guidelines are met. Documentation requirements include a valid ICD‑10 diagnosis, legible records and signatures, reporting of referring physician name/NPI when required, and appropriate ABN/modifier/occurrence reporting.
