Debridement

“We are inquiring about the use of the Q7 modifier when billing nail and callus debridement with Medicare. We are aware of the changes to the LCD with diagnosis codes. When billing nail debridement CPT 11721 and callus debridement CPT 11056, we are submitting diagnosis codes Z89.412 and Z89.422, (acquired absence of toe) with a Q7 modifier to show “non-traumatic amputation of a foot or an integral skeletal part of the foot.” Now we are being told by Medicare that per the LCD, we cannot bill those diagnosis codes even with a Q7 modifier. Should we be billing with a different modifier?”

“I am curious when and how to bill G0127 or G0247 instead of CPT code 11721 when performing Routine Foot Care.”

“Here’s the scenario: patient has a chronic ulcer left foot that comes in for regular debridements/wound care. Two weeks ago he has a full thickness ulcer and osteomyelitis at the 2nd toe right foot and I performed a partial amputation of the toe in the office. He comes in for postop check five days later and everything is fine. At his 2nd postoperative visit, I notice a new punctate ulcer plantar 2nd toe with exposed bone and progressing osteomyelitis. I did a prep and debrided the bone at this visit (Yes, authorization was submitted for a more proximal amputation at a future appointment.) I also debrided the wound on his left foot. The question I have is with a multiple modifier order/rule for the debridedment of the ulcer left foot. I billed the visit out as follows: CPT 11044-78,T6 CPT 11042-59,79,LT Should the order of the modifiers with the CPT 11042 be -59,79 or -79,59 (or does this matter?) I have seen coding recommendations that say that the 1st modifier should be the “pricing” modifier and the 2nd modifier should be the “procedure” modifier but I am not sure of this.”

“All the nails were trimmed in length with a sterile nail nipper. The leading edges were debrided with the nail bur and electric podiatry drill. The debris under the edges of the great toenails was derided with the sterile curette. Is this nail trimming (CPT 11719) since we DID NOT debride the entire nail (just edges and under toe) or can we bill as CPT 11721?”
