Question: A patient complains of chest pain (786.50) and palpitations (785.1). The cardiologist uses the hospital's equipment to perform a cardiac stress test. The physician supervises the stress test, interprets the results and issues a written report. Should I assign 93015? Michigan Subscriber Answer: No. You should reserve the global cardiovascular stress test 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) for when the cardiologist furnishes all three components of the procedure. That means the physician: 1. supervises the stress test 2. interprets the test's results and issues a written report 3. provides the equipment, pays the technical staff, provides office space, utilities, supplies and so on. Because 93015 requires furnishing the technical portion of the procedure, you shouldn't use the global code unless you're coding for a cardiologist who owns the stress test machine. - When the cardiologist instead performs the test at a hospital, the facility will be compensated for the technical portion, represented by code 93017 (... tracing only, without interpretation and report). You should then code the individual components that your physician provides. - In your scenario, you should report the physician supervision with 93016 (... physician supervision only, without interpretation and report). And code the written interpretation and report with 93018 (... interpretation and report only).
