What 93298 covers

This service evaluates data transmitted from an implanted subcutaneous cardiac rhythm monitor, often called an insertable loop recorder. The device stores automatically detected or patient-activated ECG episodes for remote review. Device clinic staff handle transmissions and alerts, while a cardiologist, electrophysiologist, or other qualified clinician interprets the rhythm findings and reports them. Monitoring may help evaluate unexplained syncope, recurrent palpitations, or atrial fibrillation after cryptogenic stroke.

Report one unit for a monitoring period of up to 30 days, not for each transmission or alert; do not report it more than once per 30 days. The record should identify the monitoring dates, data reviewed, rhythm findings, and interpretation. CMS prices the service as a diagnostic test with professional and technical components. Append modifier 26 when billing only the interpretation and report, or modifier TC when billing only the transmission, equipment, and staff portion. Bill without either modifier when one entity furnishes both portions. In-person interrogation of the same monitor is not reported during the same remote monitoring period; an in-person programming evaluation is a distinct service when performed and documented.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

93298 billing questions

How many units can be reported for multiple transmissions?

Report one unit for the monitoring period of up to 30 days, regardless of the number of transmissions or alerts. Do not report 93298 more than once per 30 days.

When should modifier 26 or TC be appended?

Append 26 when billing only the clinician's interpretation and report. Append TC when billing only the technical portion; bill the global service without either modifier when one entity furnishes both portions.

Can an in-person loop recorder interrogation be billed during the remote monitoring period?

Do not report in-person interrogation code 93291 for the same device during the 93298 remote monitoring period. In-person programming under 93285 is a different service when performed and documented.

How is 93298 different from 93297?

93298 evaluates transmitted rhythm data from an implanted subcutaneous cardiac rhythm monitor. Code 93297 concerns remote evaluation of an implantable cardiovascular physiologic monitor.

What documentation supports the professional component?

Document the monitoring dates, transmitted data reviewed, rhythm findings, and the interpreting clinician's report. An abnormal rhythm or a resulting clinical intervention is not required to document the interpretation.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
