Question: Is a peritoneal dialysis catheter site considered a skin lesion for M0440 and thus a surgical wound on M0482? Or is it considered an ostomy because it's an opening into the abdomen?
Answer: The site of a peritoneal dialysis catheter is considered a surgical wound, explains the Centers for Medicare & Medicaid Services in its OASIS questions and answers. The opening in the abdomen is referred to as the exit site and is not an ostomy.
