We did a debridement and repair of a wound dehiscence on a breast reconstruction patient. The denial said we did not have the right diagnosis code. We used S21.029A. What diagnosis code should we have used?
S21.0029A is for traumatic laceration with foreign body of unspecified breast, initial encounter. The wound was not traumatic – it was a postoperative wound healing issue. Look at the T81.31XA or T81.32XA for disruption of surgical wound.
