Frequently Asked Questions

Q. How often should a heart failure device be checked?
A. Based on Heart Rhythm Society and manufacturer guidelines, all heart failure devices (also referred to as subcutaneous cardiac rhythm monitor (ICM)) must be monitored continuously and a review of all transmissions must be done at least one time per 30 day period (12 times per year.) Each device manufacturer may have a different recommended monitoring scheduled based on the type of device and its capabilities. Please check with your device manufacturer for further guidance on heart failure transmission scheduling.

Q. What is the technical CPT code for heart failure monitoring?
A. Effective January 1, 2020, the technical CPT code for remote monitoring of heart failure devices (subcutaneous cardiac rhythm monitor systems/ICM) has changed from CPT 93299 to CPT G2066. This code is carrier based and should be used for all remote monitoring sessions that are billed after January 1, 2020. For additional information, please contact your local Medicare Adminstrative Contractor.

Q. How often can you bill 93297?
A. The professional interpretation CPT code for the remote monitoring of a heart failure device (also referred to as subcutaneous cardiac rhythm monitor system/thoracic impedance monitoring or similar) should be billed once for each 30 day period (on day 31). The professional code should be billed in conjunction with the appropriate remote monitoring technical code (CPT G2066). Please check with your device manufacturer for specific device capabilities and the recommended remote review schedule.

Q. What CPT code replaced 93299?
A. Effective January 1, 2020, CPT 93299 was replaced by CPT G2066. This code should be used for the technical CPT code for the remote monitoring of implantable loop recorders and subcutaneous cardiac rhythm monitor systems (heart failure/thoracic impedance monitoring, etc.).

Q. What is the professional CPT code for heart failure monitoring?
A. For each 30 day monitoring period, CPT 93297 should be billed once on day 31 for the review and interpretation of all transmitted patient device data by a physician or other qualified healthcare professional.
