About 93042: Limited-lead rhythm ECG interpretation
Reports a clinician’s interpretation of a one- to three-lead rhythm ECG when the professional reading is billed separately from tracing acquisition.
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.
