I have a pt with a wound dehis 2 weeks s/p TKA due to a fall onto the knee. They had exposed components. The Dr. went ahead and fully opened the incision to inspect the knee components. No exchange of components needed. The knee joint/Wound was fully irrigated with removal of a hematoma. Hemovac and layered closure done. I would appreciate any suggestions on which CPT(s) I may use for this case. Thanks!
