Ask Dr. Z

Thank you for the information on this drug test and the information included in my cardiology book. I have been working on getting this procedure code added to our system for our EP physicians to use in ordering and performing the tests. Code 93799 (unspecified code) would be used for this study. I need to provide the closest code to this unspecified code. I felt the ergonovine provocation test (93024) would be closest. I also see in the guidelines for the ergonovine test that it would include the drug used. Would this be the same case for the procainamide drug challenge? Any and all information regarding this is appreciated.
