dehisced wound/Trauma

I have a patient who had a knee replacement several years ago, patient fell and opened the incision line from the knee replacement. I have this coded as trauma wound S81.011D. The h&p information has trauma dehiscence of wound, do I also include dehiscence? How would you code this? I think this is the first one that I had like this. I would appreciate your help


  • best thing would to ask MD. it is likely not a surgical dehiscence 2 years later. most likely just a traumatic wound. If md says wound is from trauma, then code it as trauma. if they correlate it to a complication of the surgery, then code the T code.
