Cardiovascular testing
About 93024: Ergonovine coronary spasm provocation test
Reports monitored ergonovine provocation used to evaluate suspected coronary artery spasm, with supervision, interpretation, and reporting of the test.
A cardiologist or other qualified physician uses ergonovine under monitored conditions to provoke coronary vasoconstriction when coronary artery spasm is suspected. The test is commonly performed in a hospital catheterization lab, often alongside coronary angiography, so the clinical response can be assessed in the context of the patient’s symptoms and cardiac findings. It is a medication-provocation service, not an exercise stress test or a resting ECG.
Report the service when the record supports an ergonovine challenge, its clinical indication, monitoring, and the physician’s interpretation and report. CMS recognizes professional and technical components: report modifier 26 for the interpretation, modifier TC for equipment and staff, or neither modifier for the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component. The documentation should identify the test performed and its findings; routine monitoring used to conduct the challenge should not be mistaken for a separate ECG service.

- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

93024 billing questions
When should 93024 be chosen instead of 93015?
Use 93024 for ergonovine provocation when coronary artery spasm is suspected. Code 93015 describes an exercise-based cardiovascular stress test.
Which modifiers identify the professional and technical portions?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Report without either modifier for the global service.
What does the cardiovascular multiple procedure reduction affect?
It applies to the technical component when multiple cardiovascular diagnostic procedures are performed. It does not apply to the professional component under the CMS facts for this code.
Can a separate ECG be reported with the provocation test?
The test’s routine monitoring should not be treated as a separate ECG automatically. A separately performed ECG requires its own documentation and must represent a distinct service.
What documentation supports reporting 93024?
Document the suspected coronary spasm prompting the challenge, that ergonovine provocation was performed, the monitored response, and the physician’s interpretation and report.
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.
