Chromoendoscopy

Tammy Posted Tue 23rd of September, 2014 13:03:18 PM

One of our drs performed a colonoscopy on a patient with ulcerative colitis (no biopsies taken). The report states ' Chromoendoscopy was performed using methylene blue'. Is there another CPT besides 45378 that I should/can use? It should also be noted this patient has Medicare.

Thanks for your question. Chromoendoscopy involves using stains or dyes to achieve a better view of tissue. Methylene blue is used to stain cells in the small bowel, colon, and intestinal metaplasia. Chromoendoscopy has no procedure code associated with it. When completed along with a colonoscopy, the chromoendoscopy may be considered incidental to the procedure since it is only a topical application. You may use the procedure code 44799; unlisted procedure; intestine. You should submit documentation along with the claim as well as have your provider draft a letter of medical necessity to fully explain the procedure and why it was needed.
