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

This code indicates a complex tear affecting the lateral meniscus of the right knee, signifying a current injury that is still undergoing active treatment or recovery. A complex tear typically involves multiple tear patterns (e.g., horizontal, vertical, radial) within the meniscus.

This code is appropriate for follow-up visits, cast changes, or subsequent surgical interventions for a patient previously diagnosed with a complex lateral meniscus tear of the right knee. It should be used when the patient is receiving routine care during the healing phase of the injury.

• Ensure documentation specifies "complex tear" and "lateral meniscus" for accurate code assignment.
• Verify the encounter is for subsequent care, not the initial treatment of the injury.
• Always confirm laterality (right knee) is clearly documented.
