Patient had polyps removed on a previous colonoscopy.

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.
