CPT 93298 covers physician review of remote rhythm data from a subcutaneous cardiac rhythm monitor across a period of up to 30 days. Like its sibling 93297, it runs on a 30-day clock, and the periods left unbilled usually outnumber the ones denied.
What CPT 93298 covers
93298 is remote interrogation device evaluation of a subcutaneous cardiac rhythm monitor system, up to 30 days, including analysis of recorded heart rhythm data, 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: 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.
Where 93298 sits in the device monitoring family
93298 is remote evaluation of a subcutaneous cardiac rhythm monitor, including implantable loop recorders, up to 30 days. Billing it on the 90-day cycle used for pacemakers and defibrillators is the most common denial in the family. For Medicare the technical component is reported with modifier TC on 93298 itself, not with 93299. It is not remote physiologic monitoring (99453 to 99458). See the full device monitoring family map on the CPT 93294 guide.

2026 Medicare RVUs for CPT 93298

In the 2026 CMS relative value file, CPT 93298 carries 0.51 work RVUs and 3.09 total RVUs when billed globally in a non-facility setting. The global line is NA in a facility, because there the physician bills the professional component only and the facility bills the technical side. Its PC/TC indicator is 1: the code splits into a professional component (modifier 26, 0.73 total RVUs) and a technical component (modifier TC, 2.36 total RVUs), and the global line is billed only when one entity does both. Its global indicator is XXX: the surgical global period concept does not apply. Across the remote device monitoring codes, work RVUs run from 0.51 (93297) to 0.72 (93295); 93298 sits at 0.51.
To turn RVUs into payment, each component is multiplied by your locality's geographic practice cost index, the three are added, and the sum is multiplied by the 2026 conversion factor: $33.4009, or $33.5675 for qualifying APM participants (CMS-1832-F; CMS fact sheet). The CMS Physician Fee Schedule Look-Up Tool runs that calculation for your locality.
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
Subcutaneous rhythm monitors run on a 30-day period.
Fix: bill monthly rather than quarterly for this device population.
Rhythm findings not documented
The code pays for analysis of recorded heart rhythm data, which means the report needs to say what the rhythm data showed.
Fix: record the episodes reviewed, the rhythm findings and any clinical action taken.
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
93298 is the subcutaneous rhythm monitor; 93297 is the implantable cardiovascular physiologic monitor.
Fix: select from the device record.
Modifier rules
- 26 / TC: for Medicare, modifier 26 (professional) and TC (technical) apply on 93298 when two entities provide the two parts; billed globally, with no modifier, when one entity provides both.
- 59 / XE / XP / XS / XU: rarely applicable to 93298, and never a route to reporting the same 30-day period twice.
- 25: on a same-day E/M that was separately identifiable, never on the 93298 line.
- GY / GA: where a service is statutorily excluded or an advance beneficiary notice is on file, per payer instruction.
NCCI bundling edits
- 93298 with 93299: Medicare does not use 93299. The technical component is modifier TC on 93298.
- 93298 reported twice in one 30-day period: duplicate.
- 93298 with 93297: report the code matching the implanted device.
- 93298 with the pacemaker and defibrillator remote codes: different family and different period.
