Patient's has a right patellar tendon tear. Hospital repaired tear but wound became infected and dehiscenced. Do I code T81.4xxA and T81.31xA with S86.811A or just S86.811A since it's an injury?
I would code T81.4XXA (if they're on antibiotics) & T81.31XD (if they treated the dehiscence)
It really depends on the details... is the actual surgical incision dehisced? Or is it torn once again?
