What 93228 covers
This service covers a physician’s or other qualified health care professional’s review and interpretation of ECG information from remote external monitoring lasting more than 24 hours and up to 30 days, with a report. It is commonly used to evaluate intermittent symptoms such as palpitations or syncope when a standard office ECG may not capture an episode. Cardiologists and other clinicians experienced in ECG interpretation typically provide the professional service for outpatient monitoring.
Select the code for the professional interpretation and report, not for device connection, recording, or technical analysis. The record should support the monitoring period, the ECG information reviewed, the interpretation, and the resulting report. CMS treats 93228 as a professional-component-only code; the technical portion is separately represented by 93229. The professional service is not a substitute for the technical service when both were furnished.
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.

93228 billing questions
When should 93228 be chosen instead of 93272?
Use 93228 for professional review and reporting associated with remote extended ECG monitoring. Code 93272 is associated with physician review and interpretation for an external event-monitor service.
Can 93228 and 93229 be reported for the same monitoring episode?
Yes, when the professional interpretation and the technical service are both furnished. Code 93228 represents the interpretation and report; 93229 represents the technical portion.
Does 93228 include device connection or ECG recording?
No. It covers the professional interpretation and report. The technical portion is reported separately with 93229 when furnished.
Is 93228 reported for each transmission or tracing?
The code represents the professional interpretation and report for remote monitoring, not a separate charge for each transmission or tracing.
What documentation supports reporting 93228?
Document the remote monitoring period, the ECG data reviewed, the clinician’s interpretation, and the report. The record should make clear that the professional service was performed.
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.
