Necrosis of amputation stump, left upper extremity

This diagnosis code signifies the death of tissue (necrosis) occurring specifically in the residual limb after an amputation of the left arm or hand. This condition indicates a failure of the tissue to survive, often due to insufficient blood supply or infection, leading to a breakdown of the stump tissue.

Use this code when documentation clearly indicates necrosis affecting the left upper extremity amputation stump. This would apply to patients presenting with signs of tissue death, such as black or discolored tissue, sloughing, or non-healing wounds on the left residual limb. It is appropriate for both initial encounters and subsequent care related to this specific complication.

• Ensure the documentation specifies "necrosis" and clearly identifies the "left upper extremity" as the affected site.
• Do not use this code for other complications of amputation stumps, such as infection without necrosis or dehiscence.
• Consider additional codes for underlying causes of necrosis, such as peripheral artery disease or infection, if documented.
