Debridement of toenails

“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?”
