Cardiovascular testing
About 93018: Cardiovascular stress test interpretation and report only
Physician interpretation and written report of an exercise or pharmacologic cardiovascular stress test, reported when the billing physician provides the reading rather than the complete test.
This service involves reviewing ECG tracings, heart rate and blood pressure responses, symptoms, arrhythmias, and ST-segment changes recorded during a treadmill, bicycle, or pharmacologic stress test, then issuing a signed report. The report addresses ischemic findings and a conclusion, along with exercise capacity and the reason for stopping when exercise is used. Cardiologists commonly interpret stress tests performed in hospital outpatient departments or other facilities. One physician may supervise the test while a different physician interprets it.
CMS designates 93018 as a professional-component-only code for the interpretation and report. When separately billed, the equipment, staff, and tracing are represented by 93017, rather than 93018. Because 93018 already identifies the professional service, modifier 26 is not appended. A physician who both supervises and interprets a facility test may report 93016 with 93018. When one billing entity provides supervision, tracing, and interpretation, report the complete stress test with 93015 instead. Documentation should include the interpreting physician's signed findings and conclusion.

93018 billing questions
Should modifier 26 be added to this code?
No. The code itself identifies the interpretation and report, so modifier 26 is not used.
When is the global stress test code used instead of this one?
Report 93015 when the billing entity provides supervision, tracing, and interpretation, often in an office that supplies the equipment. Report 93018 when billing only for the interpretation and report.
Can the same physician bill supervision and interpretation separately?
Yes. For a facility test, a physician who both supervises and interprets it may report 93016 and 93018, while the facility provides the tracing.
Is this reported with nuclear myocardial perfusion imaging?
It may be reported alongside myocardial perfusion imaging when the stress ECG interpretation is performed and documented separately. Interpretation of the perfusion images is a distinct service.
Is it separately reportable with a stress echocardiogram?
It depends on the echocardiography code and services provided. With 93350, the stress ECG interpretation may be reported separately; 93351 includes the stress test supervision, ECG monitoring, interpretation, and report.
What documentation supports this code?
A signed report should reflect the physician's review of the tracings and hemodynamic data, relevant ST changes or arrhythmias, exercise tolerance when applicable, and a clinical conclusion.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
