What 93040 covers
This service includes a limited rhythm electrocardiogram using one to three leads, with the tracing and interpretation/report treated as a complete service. It can document rhythm during evaluation of palpitations, suspected arrhythmia, or a change in cardiac rhythm. Clinical staff may obtain the tracing in an office or bedside setting, and a qualified clinician interprets it and records the findings. Unlike a standard 12-lead ECG, this is a limited-lead rhythm study.
Report 93040 when both the tracing and interpretation/report are furnished. Documentation should support the clinical reason, the tracing obtained, and the clinician’s interpretation. When only the tracing is furnished, use 93041; when only the interpretation/report is furnished, use 93042. CMS identifies 93040 as a global service with separate codes for its technical and professional components. The cardiovascular diagnostic multiple procedure reduction affects the technical component; it does not reduce the professional component under this rule.
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.

93040 billing questions
How does 93040 differ from a complete ECG?
93040 is a limited rhythm study using one to three leads. A complete ECG uses a 12-lead tracing and is reported with 93000 when both tracing and interpretation are furnished.
Can 93040 be reported when only the tracing is performed?
No. Report 93041 for the rhythm tracing alone; 93040 includes both the tracing and interpretation/report.
What code applies when only the interpretation is furnished?
Report 93042 for the interpretation and report without the tracing. Use 93040 when both parts of the rhythm study are furnished.
Should modifiers 26 or TC be appended to 93040?
The rhythm ECG components have separate codes: 93041 for the tracing and 93042 for the interpretation/report. Use the applicable component code when only that portion is furnished.
How does the multiple procedure reduction affect 93040?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. The professional interpretation component is not reduced under this rule.
