Hi, was wondering whether or not billing for a postoperative drainage of a seroma in the 90 day global after a Parotidectomy is allowed. It’s not really a complication, rather a risk of the surgery. I was thinking 10160 with a 79 modifier. Any thoughts? The Dr. I work for is now looking into injecting Botox into this area as he has had to have it drained a couple of times. I would appreciate any help!
