What 93042 covers

93042 represents the interpretation of a limited-lead rhythm ECG, typically a short tracing used to assess heart rate and rhythm, such as when evaluating suspected atrial fibrillation, ectopy, or another arrhythmia. It covers the interpretation and written report for a one- to three-lead rhythm recording, not acquisition of the tracing. Emergency physicians, cardiologists, and other clinicians who interpret ECGs may provide this service in emergency departments, hospitals, or offices.

Report 93042 when documentation supports a rhythm tracing and a corresponding interpretation and report, including the relevant findings and impression. Select it when billing only the professional reading; the technical portion has a separate code. When the same entity provides both tracing and interpretation, 93040 represents the combined rhythm ECG service. CMS classifies 93042 as professional-component-only, so it is not split with modifier 26.

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.

93042 billing questions

What service does 93042 cover?

It covers interpretation and reporting of a one- to three-lead rhythm ECG. It does not cover acquisition of the tracing.

When should 93042 be used instead of 93040?

Use 93042 when billing only the professional interpretation and report. Use 93040 when the same service includes both the rhythm tracing and its interpretation and report.

Is the rhythm tracing included in 93042?

No. The tracing is the technical portion and has a separate code, 93041.

Should modifier 26 be appended to 93042?

No. 93042 already represents the professional interpretation and report only.

How does 93042 differ from 93010?

93042 reports interpretation of a limited-lead rhythm ECG. 93010 reports interpretation and report for a standard ECG rather than a limited-lead rhythm tracing.

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.
