Wear of artic bearing surface of int prosth r knee jt, sqla

This code signifies a long-term complication arising from the gradual wearing down of the smooth, articulating surfaces within a prosthetic right knee joint. This wear can lead to pain, instability, and reduced function of the artificial joint over time, occurring after the initial healing phase of the prosthesis implantation.

Use this code for patients presenting with symptoms or findings directly attributable to the deterioration of the bearing surface of their right knee replacement, such as chronic pain, crepitus, or loosening, that are considered sequelae. This applies to follow-up encounters addressing these persistent issues, not acute complications.

• Always assign an additional code to specify the underlying cause of the wear, if known (e.g., mechanical loosening, osteolysis).
• Ensure documentation clearly states the laterality (right knee) and that the condition is a sequela, not an acute complication.
• Distinguish from acute mechanical complications or infections of the prosthesis, which have different code categories.
