Unsp inj less saphenous at lower leg level, right leg, init

This code signifies an injury to the lesser saphenous vein in the right lower leg where the specific nature of the injury (e.g., laceration, contusion) is not documented. It indicates the initial treatment or encounter for this uncharacterized venous trauma.

This code is appropriate when a patient presents with an acute injury to the right lesser saphenous vein in the lower leg, and the medical record does not specify the type of injury. It should be used for the first time the patient is seen for this particular injury.

• Ensure the documentation clearly states the injury is to the lesser saphenous vein and on the right lower leg.
• Only use this code when the specific type of injury (e.g., puncture, crush) is unknown or not documented.
• Verify that this is indeed the patient's initial encounter for this specific injury. Subsequent encounters will require a different seventh character.
