Question #1
A patient came in for a surveillance colonoscopy for a history of polyps. However, during the procedure, the doctor took random biopsy samples due to the patient’s history of Crohn’s disease. Can I bill it as diagnosis codes Z86.010 and K50.90? Or do I have to bill it as just diagnosis code K50.90?
Answer
There is really no such thing as a history of Crohn's disease since it never is cured, so Crohn's disease is the indication. If biopsy samples of abnormal tissue were taken, this could be billed as surveillance with both Crohn's disease and the history of polyps. However, if random biopsy samples of normal tissue were taken, this would be diagnostic.
