FAQs: Frequently Asked Questions from the ASGE Coding Questions Center


Q. The coding department of the hospital where we perform our procedures has contacted our office challenging our ICD-9 coding for procedures that were originally scheduled as screening colonoscopies, but were coded with 211.3 (benign neoplasm of colon) when a polyp was identified and removed. It is the opinion of the hospital coders, based on information they received from the American Hospital Association's (AHA) Coding Clinic that, for diagnostic procedures, the primary diagnosis should always be the screening (V76.51) even when a polyp is identified and removed. It is our understanding that the primary diagnosis should be the polyp, not the screening. Who is right?

Q. If the physician does a colonoscopy with snare excision of polyps and a cautery polypectomy of another, can we charge for two polyps??
