Patient was scheduled for a complete colonoscopy. Due to poor prep, the colonoscopy was halted at the hepatic flexure. (45378-53,33). After several hours and another prep the same day, the patient had a complete colonoscopy, 45378-33. Is the first, same day, incomplete colonoscopy billable? or is just the completed colonoscopy billed? I know we can bill both if they occur on separate days. Thank you.
