Question: Would you explain when it is appropriate to use 93015 and when it would be better to bill 93016 and 93018? Answer: Billing global code 93015 (Cardiovascular stress test using maximal or submaximal treadmill or bicycle exercise, continuous electrocardiographic monitoring, and/or pharmacological stress; with physician supervision, with interpretation and report) is the right choice "when all components of the code are performed by a single entity," including use of test equipment and physician supervision, interpretation and report, says Kathy Pride, CPC, CCS-P, with QuadraMed in San Rafael, Calif. But, she says, the physician must own the stress-test equipment and the test must be performed on this equipment.

If the physician does not own the equipment and/or sends the patient to a hospital for the test, the code must be unbundled in one of the following ways:
Modifier -26 (Professional component) is partly to blame for any confusion with these codes. Whereas it is correct to use -26 to separate out the professional component of a global code, "using modifier -26 on 93015 would be inappropriate because there are codes that are specific to the professional component (93016 and 93018)," Pride says.
