Topic #: 5

[All CPC Questions]

Patient had polyps removed on a previous colonoscopy. The patient returns three months later for a follow-up examination for another colonoscopy. No new polyps are seen.

What diagnosis coding is reported for the second colonoscopy?

AZ09, Z86.010

BK63.5

CZ86.010, K63.5

DZ09, K63.5

Show Suggested Answer

Suggested Answer: A

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.

I think the correct answer is D) Z09, K63.5. The patient had polyps removed before, so this is a follow-up examination, which would be coded as Z09. The lack of new polyps suggests the previous condition, K63.5, is still applicable.

I agree with Alecia, because no new polyps were seen during the follow-up examination.
