Mech compl of internal right knee prosthesis, init encntr

This code signifies a mechanical issue, other than fracture or dislocation, involving an artificial right knee joint. It indicates that the prosthesis itself is experiencing a problem, such as loosening, breakage of an internal component, or wear, rather than an infection or trauma to the surrounding tissue. This is an initial encounter for the specific complication.

Use this code when a patient presents with symptoms directly attributable to a mechanical failure of their right knee prosthesis, such as pain, instability, or decreased range of motion, and the provider documents a specific mechanical complication other than a fracture or dislocation. This applies to the initial evaluation and treatment of the complication.

• Ensure documentation clearly specifies "right knee" and "internal prosthesis."
• Verify the complication is mechanical and not an infection (T84.5x) or a fracture/dislocation (T84.01x, T84.02x).
• Confirm this is the initial encounter for this specific complication; subsequent encounters would use a different seventh character.
