Tear of articular cartilage of left knee, current, subs

This code signifies a tear in the articular cartilage of the left knee that is currently being treated, but the patient is beyond the initial phase of care. It indicates that the injury is not new, but rather an ongoing condition requiring continued management.

This code is appropriate for follow-up visits, rehabilitation sessions, or subsequent surgical encounters for a left knee articular cartilage tear. It should be used when the patient is receiving active treatment for the injury after the initial diagnosis and treatment plan have been established.

• Ensure documentation clearly states "left knee" and "articular cartilage tear."
• Verify that the encounter is not the initial treatment for the injury; look for terms like "follow-up," "re-evaluation," or "post-operative care."
• Always check for laterality (left vs. right) and the specific type of cartilage involved.
