Necrosis of amputation stump, right upper extremity

This code signifies the death of tissue in the remaining portion of a right upper limb following an amputation. This tissue death, or necrosis, can be a serious complication, potentially leading to infection, delayed healing, or the need for further surgical intervention.

Apply this code when documentation clearly indicates necrosis affecting the stump of a right upper extremity amputation. This includes cases where the necrosis is identified during follow-up care for an existing amputation or as a new complication.

• Ensure laterality is explicitly documented as "right upper extremity."
• Look for terms like "gangrene," "tissue death," or "non-viable tissue" specifically affecting the amputation site.
• Code any associated infections or complications separately, if documented.
