R02.02: Necrosis of skin and subcutaneous tissue, not elsewhere classified: Forearm and wrist

Some of the skin on your forearm has died.

The skin is supplied with oxygen and nutrients through the blood. If, for example, the skin is not supplied with enough blood or any at all, this area of the skin can die. The skin in the affected area often turns black. The area of dead skin can also become inflamed. That can occur for instance due to pathogens.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
