CPT 93297 covers physician review of remote data from an implantable cardiovascular physiologic monitor across a period of up to 30 days. The 30-day cycle is what separates it from the pacemaker and defibrillator codes, and getting that wrong is the usual reason it denies.
What CPT 93297 covers
93297 is remote interrogation device evaluation of an implantable cardiovascular physiologic monitor system, up to 30 days, including analysis of one or more recorded physiologic cardiovascular data elements from internal and external sensors, with analysis, review(s) and report(s) by a physician or other qualified health care professional.
For Medicare, the technical component travels on this code: it is billed globally when one entity provides both parts, or split with modifier 26 (professional) and TC (technical) when two entities do. The old technical code 93299 and the Medicare code G2066 are not used for that.
How the remote device monitoring family is organised
Pacemakers and defibrillators use a professional code and a technical code. Implantable monitors changed for Medicare in 2024, so read the last three lines carefully.
- 93294: pacemaker system, remote, physician analysis, review and report. Up to 90 days.
- 93295: implantable defibrillator system, remote, physician analysis, review and report. Up to 90 days.
- 93296: pacemaker or defibrillator system, remote, technical. Data acquisition, receipt of transmissions, technician review, technical support and distribution of results. Up to 90 days.
- 93297: implantable cardiovascular physiologic monitor, remote evaluation. Up to 30 days.
- 93298: subcutaneous cardiac rhythm monitor, including implantable loop recorders, remote evaluation. Up to 30 days.
- 93299: CPT's technical-only code for those two monitor types. Medicare does not use it. CMS created G2066 for the technical component in 2020, deleted G2066 for 2024, and accepted the practice-expense inputs on 93297 and 93298 instead. For Medicare the technical component is reported with modifier TC on 93297 or 93298.
Not the same as remote physiologic monitoring
These codes are frequently confused with the remote physiologic monitoring family (99453, 99454, 99457 and 99458), which covers monitoring of physiologic parameters such as weight, blood pressure and pulse oximetry using a supplied device.
They are different services with different rules, different time periods and different documentation. A cardiac implantable device being monitored remotely belongs in the 93294 to 93299 family. Billing it under the RPM codes, or the reverse, produces denials that look mysterious until the families are separated.
Reimbursement context
Remote monitoring is a recurring revenue stream rather than a one-off procedure, so the economics depend on billing every eligible period exactly once.
Medicare pays for this code under the Physician Fee Schedule, and the amount depends on where you practise. Each code carries relative value units for physician work, practice expense and malpractice, each adjusted by a geographic practice cost index (GPCI) for the locality, and the total is multiplied by the conversion factor:
(work RVU × work GPCI + practice expense RVU × PE GPCI + malpractice RVU × MP GPCI) × conversion factor
For 2026 the conversion factor is $33.4009 for practitioners who are not qualifying APM participants and $33.5675 for qualifying APM participants, as set in the CY 2026 Physician Fee Schedule final rule (CMS-1832-F; see the CMS fact sheet). Because the RVUs differ by code and the GPCIs differ by locality, what your practice is paid will differ from any national average. Pull the RVUs and the payment for your own locality from the CMS Physician Fee Schedule Look-Up Tool.
Documentation requirements
- The device type and model, and the date of implant.
- At least one transmission received and reviewed within the 30-day period.
- The dates the monitoring period began and ended.
- The data elements reviewed, not merely that a transmission arrived.
- A dated, signed report of the analysis and any clinical action taken, where the professional component is billed.
- Evidence of the technical infrastructure and technician review, where the technical component is billed.
- Confirmation that the period has not already been billed for this patient and device.
Common denials and the exact fix
Reported more than once in the same period
The most common denial in this family. The code covers the whole monitoring period, so a second claim inside it is a duplicate no matter how many transmissions arrived.
Fix: track the period start date per patient and per device, and let the billing system rather than the calendar month drive the claim.
No transmission received in the period
A period with no transmission does not support the code, even where the equipment was in place and the patient was enrolled.
Fix: confirm at least one transmission was received and reviewed before billing, and work the non-transmitting patient list as an operational task rather than a billing one.
Billed on a 90-day cycle
Implantable monitors run on a 30-day period, not the 90-day period used for pacemakers and defibrillators. Billing quarterly leaves two out of every three eligible periods unbilled.
Fix: separate the 30-day device population from the 90-day population in the billing schedule. This error usually runs in the practice's disfavour.
Data elements reviewed but not documented
The code pays for analysis of recorded physiologic data elements. A report that states a transmission was received does not establish the analysis.
Fix: record which data elements were reviewed and what they showed.
93299 or G2066 billed for the technical component
G2066, the Medicare code created in 2020 for this technical component, was deleted for 2024, and CMS accepted the practice-expense inputs on 93297 and 93298 instead. Medicare does not use 93299 as a separate line.
Fix: for Medicare, report the technical component with modifier TC on 93297 or 93298, or bill the code globally when one entity provides both parts. Check whether each commercial payer still accepts 93299.
Wrong monitor code selected
93297 covers a cardiovascular physiologic monitor; 93298 covers a subcutaneous cardiac rhythm monitor. They are different devices.
Fix: select from the device record rather than a template default.
Modifier rules
- 93294, 93295, 93296: no 26 or TC. The professional and technical work is split through separate codes, so appending a component modifier is redundant and can cause a rejection.
- 93297, 93298: for Medicare, modifier 26 (professional) and TC (technical) apply when two entities provide the two parts. Billed globally, with no modifier, when one entity provides both.
- 59 / XE / XP / XS / XU: rarely applicable, and never a route to reporting the same monitoring period twice.
- 25: on an E/M where a separately identifiable visit occurred, never on the monitoring code.
- GY / GA: where a service is statutorily excluded or an advance beneficiary notice is on file, per payer instruction.
NCCI bundling edits
- 93297 with 93299: Medicare does not use 93299. The technical component is modifier TC on 93297.
- 93297 reported twice in one 30-day period: duplicate.
- 93297 with 93298: report the code matching the implanted device.
- 93297 with 93294, 93295 or 93296: different device family and different period.
- 93297 with the remote physiologic monitoring codes: different family and different service.
