Necrosis of amputation stump, right lower extremity

This diagnosis code signifies the death of tissue (necrosis) occurring specifically on the residual limb following an amputation of the right lower extremity. This tissue death can range from superficial skin involvement to deeper muscle or bone necrosis, impacting the integrity and healing of the stump.

Use this code when documentation clearly indicates necrosis affecting the right lower extremity amputation stump. This typically occurs in patients experiencing complications such as infection, poor circulation, or pressure injuries on the residual limb. It is appropriate for both acute and chronic presentations of stump necrosis.

• Ensure the documentation specifies "necrosis" and not just general wound complications or infection without tissue death.
• Verify the laterality is explicitly stated as "right lower extremity" to avoid miscoding.
• Consider additional codes for underlying causes (e.g., diabetes, peripheral artery disease) or associated conditions (e.g., infection) if documented.
