Injury to other specified blood vessels of lower extremity

This diagnosis code signifies damage to specific, non-major blood vessels within the lower limb, excluding the main arteries and veins like the femoral or popliteal. This injury could involve a laceration, contusion, rupture, or other trauma to smaller arteries, veins, or capillaries in the leg, ankle, or foot. It indicates an acute vascular insult requiring medical attention.

Use this code when documentation specifies an injury to a named, but not major, blood vessel of the lower extremity, such as a peroneal artery branch, a saphenous vein tributary, or other smaller vascular structures. This code is appropriate for traumatic injuries identified through imaging (e.g., angiography, ultrasound) or direct surgical visualization. Documentation should clearly identify the injured vessel and its location within the lower limb.

• Ensure the documentation specifies "other specified" blood vessels; avoid using for major named arteries or veins.
• Always code the underlying cause of the injury (e.g., fracture, open wound) first, followed by this code as a secondary diagnosis.
• Distinguish from codes for unspecified blood vessel injuries or injuries to major vessels of the lower extremity.
