Prph tear of medial mensc, current injury, unsp knee, subs

This code signifies a fresh tear located on the inner side of the knee's medial meniscus, where the tear extends to the periphery of the cartilage. It indicates that the patient is receiving follow-up care for this specific injury, rather than the initial diagnosis or treatment.

Apply this code when a patient presents for subsequent treatment, such as physical therapy, follow-up appointments, or cast changes, for a recently sustained peripheral tear of the medial meniscus. This code is appropriate when the medical record does not specify which knee is affected.

• Ensure documentation clearly states "subsequent encounter" for this specific injury.
• Verify the tear is described as "peripheral" and involves the "medial meniscus."
• Only use this code when the laterality (left or right knee) is not documented.
