Question: I heard CPT® has a different code for colonoscopies performed through a colostomy bag. I’m at a lost finding a code for the tattooing of a polyp when the procedure was done this way. What should I report?

Answer: No specific CPT® code exists for tattooing when the physician performs colonoscopy via stoma.
For standard colonoscopy, you would use 45381 (Colonoscopy, flexible; with directed submucosal injection[s], any substance) for tattooing or any other type of injection, but you won’t find an injection code within the family of codes for colonoscopy through a stoma.
If the GI performs a colonoscopy via stoma and takes a biopsy, then you should report 44389 (Colonoscopy through stoma; with biopsy, single or multiple).
Otherwise, bill 44388 (Colonoscopy through stoma; diagnostic, including collection of specimen[s] by brushing or washing, when performed [separate procedure]) for a diagnostic procedure. You would need to use the “unlisted” code 44799 (Unlisted procedure, small intestine) for the tattooing portion of the colonoscopy via stoma procedure. The added fee of less than 0.5 RVUs is probably not worth the hassle of submitting all the info needed for an unlisted code claim.
