What diagnosis coding is reported for the second colonoscopy?
Suggested Answer: A Vote an answer
For a follow-up examination after the removal of polyps with no new polyps found, the appropriate diagnosis codes are:
* Z09: Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm.
* Z86.010: Personal history of colonic polyps.
Using Z09 indicates that the follow-up exam is to check the patient after treatment, and Z86.010 indicates a history of colonic polyps, which is relevant to the patient's medical history.
