S80-S89: Injuries to the knee and lower leg

S89: Other and unspecified injuries of lower leg

Other and unspecified injuries of lower leg (S89) refers to a wide array of injuries that occur in the area of the body from the knee to the ankle, excluding the knee and ankle themselves. It's typical that such injuries arise from accidents, sports, falls, or direct blunt force, and they can range from superficial wounds or bruises to severe injury to the muscles, tendons, bones, and blood vessels of the lower leg. These injuries may exhibit symptoms such as pain, swelling, bruising, difficulty in movement or weight-bearing, or an abnormal shape or position of the lower leg. It's noteworthy that the rate and sequence in which these conditions may progress is dependent on their severity and the specific structure of the lower leg that is affected. Diagnostic tests like X-rays, CT scans, or MRI may be used to determine the exact nature and extent of the injury.
