Complex tear of lat mensc, current injury, left knee, subs

This code signifies a complex tear affecting the lateral meniscus of the left knee, which is currently being treated. A complex tear involves multiple planes or patterns of tearing within the meniscus, often including both horizontal and vertical components. This injury is in a healing or recovery phase, not the initial acute presentation.

Use this code when documenting follow-up care for a patient with a previously diagnosed complex lateral meniscus tear of the left knee. This includes visits for physical therapy, post-operative checks, medication management, or further diagnostic imaging during the healing process. It is appropriate for any encounter after the initial treatment of the injury.

• Ensure documentation specifies "complex tear" and "lateral meniscus" for the left knee.
• The "D" seventh character indicates subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use for the initial diagnosis or for sequelae (late effects) of the injury.
