AAPC Certified Professional Coder (CPC) — Question 3

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?

Answer options

• A. Z09, Z86.010
• B. K63.5
• C. Z86.010, K63.5
• D. Z09, K63.5

Correct answer: A

Explanation

The correct answer is A, Z09 and Z86.010, which indicate follow-up after polypectomy and a personal history of colon polyps, respectively. Option B (K63.5) only accounts for the presence of polyps and does not indicate the patient's follow-up status. Options C and D include K63.5 and do not fully capture the follow-up coding needed after previous polypectomy.
