I am in urology specialty. Often times we have a patient come in for a scheduled cystoscopy (diagnostic procedure), and a lesion is discovered, and/or the provider decides to pursue surgery after the cystoscopy for a variety of reasons; sometimes a transurethral resection of prostate. Anyhow, we have been told before that it may be appropriate to bill an E/M on the same date as the cystoscopy if the plan changes and the other requirements of the E/M have been met such as the Hx and Exam level. I struggle with this concept especially given that it is a diagnostic procedure in nature and that it would be expected to gain information and do something with that information afterwards. Does anyone have any thoughts on this situation and how it should be billed. Thank you.
