Remote monitoring of implanted cardiac devices is billed with five CPT codes. CPT 93294 (pacemakers) and 93295 (ICDs) are 90-day professional codes, each paired with 93296 for the technical work. CPT 93297 (implantable physiologic monitors used for heart failure) and 93298 (implantable loop recorders) are 30-day codes billed globally or split into professional and technical components.
This guide matches each code to its device type and explains the monitoring periods and documentation behind a clean claim. It reflects the CPT code set in effect for 2026. Payment amounts vary by locality and payer, so confirm current rates in the Medicare Physician Fee Schedule and with your payers before billing.
Which CPT code applies to which cardiac device?
- Pacemaker or CRT-P, including leadless pacemakers: 93294 (professional) plus 93296 (technical), once per 90 days.
- ICD or CRT-D, including subcutaneous ICDs: 93295 (professional) plus 93296 (technical), once per 90 days.
- Implantable cardiovascular physiologic monitor (heart failure data): 93297 global, or 93297-26 (professional) and 93297-TC (technical), once per 30 days.
- Implantable loop recorder or insertable cardiac monitor: 93298 global, or 93298-26 (professional) and 93298-TC (technical), once per 30 days.
What do CPT codes 93294, 93295 and 93296 cover?
CPT 93294: pacemaker remote interrogation (professional)
CPT 93294 covers remote interrogation device evaluation of a single, dual or multiple lead pacemaker system, or a leadless pacemaker, for up to 90 days. It includes the physician or qualified health care professional's analysis, review and report of the interim transmissions received during that period. It is a professional-only code and is reported once per 90-day period, no matter how many transmissions arrive.
CPT 93295: ICD remote interrogation (professional)
CPT 93295 is the matching professional code for implantable cardioverter-defibrillators: single, dual or multiple lead systems, including CRT-D and subcutaneous ICDs, for up to 90 days. A defibrillator that also paces is reported with 93295 alone, so 93294 and 93295 are not reported together for the same device and period.
CPT 93296: technical component for pacemakers and ICDs
CPT 93296 covers the technical work behind a 90-day pacemaker, leadless pacemaker or ICD monitoring period: remote data acquisition, receipt of transmissions, technician review, technical support and distribution of results. It pairs with 93294 or 93295. It does not apply to loop recorders or physiologic monitors, which carry their own technical components under 93297-TC and 93298-TC.
How does the 90-day monitoring period work?
CPT 93294, 93295 and 93296 are each reported once per 90 days. CPT instructions say not to report them when the monitoring period is shorter than 30 days. Most clinics report the service at the close of the period; confirm the date-of-service convention your Medicare Administrative Contractor uses.
What do CPT codes 93297 and 93298 cover?
CPT 93297: implantable cardiovascular physiologic monitor
CPT 93297 covers remote interrogation, for up to 30 days, of an implantable cardiovascular physiologic monitor system. It includes analysis of one or more recorded physiologic cardiovascular data elements from all internal and external sensors, with review and report by a physician or qualified health care professional. Clinics use it for heart failure diagnostic monitoring. It can be reported globally, or split into 93297-26 for the professional component and 93297-TC for the technical component.
CPT 93298: implantable loop recorder
CPT 93298 covers remote interrogation, for up to 30 days, of a subcutaneous cardiac rhythm monitor system, the CPT term for an implantable loop recorder or insertable cardiac monitor. It includes analysis of recorded heart rhythm data with review and report. Like 93297, it can be reported globally or split into 93298-26 and 93298-TC.
How does the 30-day monitoring period work?
CPT 93297 and 93298 are each reported once per 30 days, regardless of how many transmissions the device sends. CPT instructions say not to report them when the monitoring period is shorter than 10 days. HCPCS code G2066, which once carried the technical component for these devices, was deleted on January 1, 2024; the technical work is now reported with the -TC modifier.
How are professional and technical components billed?
CPT 93294 and 93295 are professional only, and 93296 is technical only. For 93297 and 93298, the global code is used when one entity performs both the interpretation and the technical service. When the work is split, the physician practice reports the -26 component and the entity performing the technical service reports the -TC component.
Octagos supports several service models, including split-billing arrangements. Your Octagos team can confirm which entity reports each component under your agreement.
What documentation does a remote monitoring claim need?
Each claim should be supported by the monitoring period dates, the device type and manufacturer, and an interpretation report signed by a physician or qualified health care professional. The report should address device function, battery and lead status, programmed parameters, recorded arrhythmia episodes and any actionable findings with the follow-up taken.
How does Octagos support CPT code compliance?
Octagos tracks the monitoring period for every active patient so each claim is reported in the right window. Every report follows the same structure, so documentation is billing-ready and consistent across sites. Atlas AI™ prioritizes each transmission by clinical acuity, and in the Two-Brain Approach™ model a qualified clinician reviews every transmission. Finished reports reach the clinic through more than 250 live integrations across 20+ EHR systems.
Frequently asked questions
What is the difference between CPT 93294 and 93296?
CPT 93294 is the professional component for pacemaker monitoring: the physician or qualified health care professional's review and report. CPT 93296 is the technical component: data acquisition, technician review and distribution of results. They cover the same 90-day period and are reported together.
Can CPT 93294 and 93295 be billed for the same patient?
Not for the same device and period. A pacemaker is reported with 93294, and an ICD or CRT-D, including one that paces, is reported with 93295. Either one pairs with 93296.
Is there still a separate technical code for loop recorders?
No. HCPCS G2066 was deleted on January 1, 2024. The technical component for loop recorder monitoring is now reported as 93298-TC, and for physiologic monitors as 93297-TC.
How often can each code be billed?
CPT 93294, 93295 and 93296 can be reported once per 90 days, with a minimum of 30 days of monitoring. CPT 93297 and 93298 can be reported once per 30 days, with a minimum of 10 days of monitoring.
Can cardiac device monitoring be billed with RPM codes 99453 and 99454?
Remote monitoring of an implanted cardiac device is reported with the device-specific codes in this guide. The general remote physiologic monitoring codes describe a separate service, and CMS has proposed changes to RPM coding, so check current CMS guidance and your payer policies before combining them.
