What 93016 covers
This service covers a practitioner's supervision during a cardiovascular stress test, not production of the tracing or interpretation of the results. The patient may exercise on a treadmill or stationary bicycle or receive a pharmacologic stress agent such as regadenoson or dobutamine. ECG is monitored continuously while heart rate, blood pressure, symptoms, and responses that might require stopping the test are assessed. A physician or other qualified health care professional typically supervises the test in a cardiology office, hospital outpatient stress lab, or nuclear cardiology suite.
Report 93016 for the supervision portion when the complete stress test service is not reported by one provider. Code 93017 covers the technical tracing, and 93018 covers interpretation and report; report each portion only when furnished by the billing entity. If one provider furnishes all portions, report 93015 instead of the separate codes. CMS identifies 93016 as professional-only, so modifier 26 is not appended; the technical portion has a separate code. Documentation should identify the supervisor, stress protocol or agent, monitoring, patient response, and reason the test ended.
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.

93016 billing questions
When should 93016 be reported instead of 93015?
Report 93016 when billing the supervision portion separately. Use 93015 when one provider furnishes the complete stress test service, including supervision, tracing, interpretation, and report.
Does 93016 need modifier 26?
No. CMS identifies 93016 as professional-only; 93017 separately describes the technical tracing portion.
Can one physician bill 93016 and a different physician bill 93018?
Yes. The practitioner who supervises may report 93016, while a different practitioner who interprets the stress test and prepares the report may report 93018.
Is 93016 reported with a nuclear myocardial perfusion study?
It may be reported with SPECT myocardial perfusion imaging, such as 78452, when cardiovascular stress test supervision is furnished separately. Report the other stress test portions according to who furnishes them.
Can 93016 be billed with a stress echocardiogram?
Do not separately report 93016 with 93351, which includes stress ECG supervision. When stress echocardiography is reported with 93350, the separately furnished stress ECG supervision may be reported with 93016.
Is a pharmacologic stress agent included in 93016?
No. Code 93016 covers supervision, not the supplied drug. When the reporting entity supplies regadenoson for the test, J2785 identifies that drug separately.
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.
