Inj lesser saphenous vein at lower leg level, left leg, subs

This code signifies a documented injury to the lesser saphenous vein in the left lower leg, which is not a laceration or puncture wound, and is being treated during a follow-up visit. This could encompass various types of damage to the vein, such as a contusion, crush injury, or other non-open trauma. The "subsequent encounter" indicates that the patient is receiving routine care during the healing or recovery phase of the injury.

Apply this code when a patient presents for follow-up care of a previously diagnosed, non-laceration/puncture injury to the left lesser saphenous vein at the lower leg level. This is appropriate for visits related to wound care, monitoring healing progress, or managing complications arising from the initial injury. It should not be used for the initial treatment of the injury.

• Ensure documentation clearly specifies the left lower leg and the lesser saphenous vein.
• Verify that the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Confirm the injury type is "other specified" and not a laceration (S85.41-) or puncture (S85.42-).
