I have a procedure were the docs postop diagnosis is Achilles tendinitis and calcaneal spur. I know that if they remove the achilles to get to the spur it is incidental. but she was seen for Achilles tendinitis in the past. the doc had to do debridement of partial thickness when he removed the spur and re attached the achilles. Would that allow me to bill 27654 with 59 and tendinitis dx?
