Tear of articular cartilage of right knee, current, subs

This code signifies a tear in the articular cartilage of the right knee, indicating an injury to the smooth, protective tissue covering the ends of the bones within the knee joint. This injury is currently being treated, and the patient is in a phase of recovery or follow-up care.

Apply this code when a patient presents for ongoing treatment, follow-up, or rehabilitation for a previously diagnosed tear of the right knee's articular cartilage. This includes visits for physical therapy, medication management, or post-surgical care related to the initial injury.

• Ensure documentation specifies "right knee" and "articular cartilage" to support this code.
• The "XD" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial diagnosis or active treatment of complications; those require different seventh characters.
