What is a cups code for surgery? i know of icd codes, but cups is that international or what is it exactly?

You probably are referring to a CPT code. ICD codes describe diagnoses. CPT codes describe provider interactions with patients - office visits, consultations, treatments, etc.

Are you referring to CPT Code used for preoperative clearance? These are codes used for coding for testing and examination done prior to the surgery to identify and modify risks of medical including cardiac postoperative complications. Hope it helps.
