L98.4: Chronic ulcer of skin, not elsewhere classified

You have had an open wound for a long time.

These wounds can occur, for example, when the blood supply to the skin is insufficient or when the immune system is weak. Open wounds are also sometimes caused by certain pathogens.

Open wounds can be sore or itchy. The skin in those areas can also become inflamed more easily. Sometimes you can also have no symptoms at all. The skin around the open wound can also change and be pale or blueish.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
  • B: Both sides
