CPT code 93745: Wearable defibrillator setup, initial setup and instruction2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93745 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93745 covers

This service sets up a wearable cardioverter-defibrillator, configures it for use, and instructs the patient or caregiver. Cardiology teams use it for temporary protection from sudden cardiac arrest when risk is elevated but an implanted defibrillator is not yet appropriate, including periods of recovery or reassessment before an implant decision. Later in-person review of recorded wearable-device data is a separate service.

Medicare assigns CPT 93745 carrier-priced status (C): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. For component billing, modifier 26 identifies the professional interpretation component, and modifier TC identifies the technical equipment-and-staff component; billing without either modifier represents the global service. Report initial wearable-device setup and instruction here, rather than an implanted-defibrillator programming visit.

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.
