Sorry to bring back this topic, but I came across the same question in a recent audit.
The note I'm auditing states:
*Blah blah blah colonoscopy bit*
Four benign appearing sessile polyps were found in the rectum. The polyps
were 2 to 4 mm in size. These polyps were removed with a cold biopsy
forceps. Resection and retrieval were complete. Two polyps were found in the
cecum. The polyps were diminutive in size. These polyps were removed with a
cold biopsy forceps. Resection and retrieval were complete.
So I came here seeking advice. Here are the choices:
45380 Colonoscopy, flexible, proximal to splenic flexure; with biopsy, single or multiple
45381 Colonoscopy, flexible, proximal to splenic flexure; with directed submucosal injection(s), any substance
45382 Colonoscopy, flexible, proximal to splenic flexure; with control of bleeding (eg, injection, bipolar cautery, unipolar cautery, laser, heater probe, stapler, plasma coagulator)
45383 Colonoscopy, flexible, proximal to splenic flexure; with ablation of tumor(s), polyp(s), or other lesion(s) not amenable to removal by hot biopsy forceps, bipolar cautery or snare technique
45384 Colonoscopy, flexible, proximal to splenic flexure; with removal of tumor(s), polyp(s), or other lesion(s) by hot biopsy forceps or bipolar cautery
45385 Colonoscopy, flexible, proximal to splenic flexure; with removal of tumor(s), polyp(s), or other lesion(s) by snare technique
Since there wasn't a submucosal injection, that rules out 45381. No control of bleeding rules out 45382. Since the note states he used cold biopsy forceps, we can't use 45383-45385. Seems like even though the procedure was a complete removal, the most accurate code is 45380.
