Implantable Loop Recorder Monitoring

Q. How often should an implantable loop recorder (Reveal, Reveal LINQ, Confirm, Confirm RX, Bio2) be checked?
A. Based on Heart Rhythm Society and manufacturer guidelines, all implantable loop recorders 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.) While these devices may automatically trigger many times per month, both the technical and professional CPT codes are only billed once per 30 day period (day 31).

Q. What is the technical monitoring CPT code for an implantable loop recorder?
A. The technical CPT code for remote monitoring of implantable loop recorders has changed from CPT 93298-TC. This is now a nationally recognized code. For additional information, please contact your local Medicare Administrative Contractor.

Q. What is the professional interpretation CPT code for an implantable loop recorder?
A. The review and professional interpretation of all transmissions of an implantable loop recorder for each 30-day period should be billed under CPT 93298-26. This code should be completed by a physician or other qualified health care professional.

Q. How often can you bill CPT 93298?
A. The global CPT code for the remote monitoring of implantable loop recorders is 93298. If the test is being performed by separate facilities (technical vs professional), the technical modifier -TC and the professional modifier -26 should be billed for each 30-day period (on day 31).

Q. How often can you bill 93298?
A. The professional interpretation CPT code for the remote monitoring of an implantable loop recorder 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).

Q. Is the interrogation for a loop recorder required to be done in the office?
A. No. It is the standard of care for all implantable loop recorders to be monitored remotely. All scheduled and unscheduled transmissions should be reviewed in a timely manner with billing taking place every 31 days for the preceding 30 day monitoring period. Rarely, changes in how the device is placed or functions may need to be done in a medical facility. In person programming or changes do not affect the remote monitoring schedule. Older, legacy devices may not have remote transmission capability and may need to be checked in the office.

Q. If a device manufacturer representative performs the technical monitoring for an implanted loop recorder, can the physician bill for remote monitoring?
A. In this situation, the physician may bill on the 30 day cycle for the professional CPT code (CPT 93298) only. In order for the physician or facility to bill for both the professional and technical CPT codes, the technical remote monitoring must be performed by a qualified employee or a certified monitoring service.
