Prph tear of medial meniscus, current injury, l knee, subs

This code signifies a recent injury involving a tear in the outer edge of the medial meniscus in the left knee. The medial meniscus is a C-shaped cartilage that acts as a shock absorber and stabilizer within the knee joint. A peripheral tear indicates the tear is located in the vascularized zone of the meniscus.

Use this code for follow-up encounters, such as cast changes, medication adjustments, or wound care, for a patient who has sustained a peripheral tear of the medial meniscus in their left knee. This applies when the patient is still receiving active treatment for the initial injury.

• Ensure documentation clearly specifies "left knee" and "peripheral tear" of the medial meniscus.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase and still receiving active treatment.
• Do not use for initial treatment (use "A" for initial encounter) or for sequelae/late effects (use "S" for sequela).
