An 83-year-old female, status post partial hip replacement, presents after falling from her wheelchair. The patient was found to have a left posterior superior dislocation of her hemiarthroplasty. What are the appropriate ICD-10-CM code assignments for the traumatic dislocation of left hip prosthesis? Is the dislocation considered a complication even though it is due to an injury?
Assign code T84.021A, Dislocation of internal left hip prosthesis, initial encounter, and code W05.0XXA, Fall from non-moving wheelchair, initial encounter, for traumatic dislocation of the left hip prosthesis. A dislocation of a prosthetic joint would be coded as a complication even though the dislocation occurred secondary to trauma (fall from wheelchair).
Complications of prosthetic joint replacements can occur due to infection, loosening of the prosthesis, dislocation of the prosthetic joint (traumatic or non-traumatic), periprosthetic fracture, articular surface wearing, and/or osteolysis.
