Complex tear of medial mensc, current injury, r knee, init

This code signifies a severe, intricate tear of the medial meniscus in the right knee, occurring recently. A "complex" tear implies multiple tear patterns (e.g., horizontal, vertical, radial) or a combination of these, making it more challenging to repair than a simple tear. This injury typically results in significant pain, swelling, and mechanical symptoms like locking or catching.

Assign this code for a patient presenting with a newly diagnosed, acute complex tear of the right medial meniscus. This is appropriate when the patient is receiving initial active treatment for the injury, such as surgical repair or conservative management. It should be used for the first encounter related to this specific injury.

• Ensure documentation clearly specifies "complex" tear and "medial" meniscus.
• Verify the laterality is "right knee" and the injury is "current" or "acute."
• Only use the "A" seventh character for the initial encounter for active treatment of the injury.
