Mech compl of internal right knee prosthesis, sequela

This code signifies a long-term or residual issue stemming from a mechanical problem with an internal prosthetic device in the right knee. It covers complications that are not specifically classified elsewhere, such as fracture of the prosthesis, dislocation, or periprosthetic infection, but are still directly related to the device's mechanical function.

Use this code for patients presenting with chronic pain, limited range of motion, instability, or other persistent symptoms in the right knee that are attributed to a past mechanical complication of their internal knee prosthesis. This applies when the acute phase of the complication has resolved, but its effects continue to impact the patient. It is appropriate for follow-up care related to such a complication.

• Requires a seventh character "S" to indicate sequela, meaning the complication's effects are long-standing.
• Ensure documentation clearly links the current condition to a previous mechanical complication of the right knee prosthesis.
• Do not use for acute or current mechanical complications; those would typically use the "A" (initial encounter) or "D" (subsequent encounter) seventh character.
