Could someone please clarify something. For the screening codes, for example Z12.11 encounter for screening for malignant neoplasm of colon. Is it alright to pick up this code for the ordering of a colonoscopy , or should this be only for the encounter of the colonoscopy? We have providers/coders picking this code up for whenever the provider is ordering the colonoscopy and also if the patient is in for a pre-op for the colonoscopy. If someone could clarify this , please do. THanks!
