Our physician did a colonoscopy on a patient that was incomplete. I billed it as such with a modifier 53. Now the doctor would like the patient to have a virtual colonoscopy. I'm not sure what ICD9 code to use to report a failed colonoscopy? Is there one? Of course the original dx for the colonoscopy will be used as well. They were rectal bleeding and history of colon polyps. Thank you.
