Question:
Histology/Polyp--Colon: Which histology code is used when a colon biopsy states adenocarcinoma arising in a polyp, but the resection path states only adenocarcinoma, and does not mention arising in a polyp. See Discussion.
Discussion:
This scenario occurs frequently and our QC staff is divided on which code to use.
03-24-06 Rectal Polyp: Adenocarcinoma, moderately differentiated. 6-29-06 Rectum: Adenoca, MD, invades into the submucosa. No malignancy (0/15) LNs.
Answer:
Use the polyp information from the biopsy and code adenocarcinoma arising in a polyp (8210, 8261 or 8263 as appropriate).
