Laceration of popliteal artery, left leg, subs encntr

This diagnosis code indicates a tear or cut in the popliteal artery located in the back of the left knee, specifically documented during a subsequent encounter for this injury. The popliteal artery is a major blood vessel supplying blood to the lower leg and foot. Such an injury can lead to significant blood loss and compromise distal circulation.

Apply this code when a patient is being seen for follow-up care, rehabilitation, or further treatment related to a previously diagnosed laceration of the left popliteal artery. This includes scenarios where the patient is returning for wound care, assessment of healing, or management of complications arising from the initial injury.

• Ensure documentation clearly specifies "left leg" and "popliteal artery" for accurate laterality and anatomical site.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the underlying cause of the laceration (e.g., trauma, penetrating injury) as an external cause code (V00-Y99) in addition to this diagnosis.
