Neuroma of amputation stump, unspecified extremity

This code signifies the presence of a neuroma, a benign tumor of nerve tissue, within the residual limb following an amputation. It indicates nerve regeneration that has become disorganized, often forming a painful mass at the end of a severed nerve. This condition can cause significant localized pain and discomfort for the patient.

Use this code when documentation clearly indicates a neuroma of an amputation stump, and the specific extremity affected is not specified. This diagnosis is typically made based on clinical examination, patient symptoms (e.g., localized pain, tenderness, altered sensation), and sometimes imaging studies. It is appropriate for both initial and subsequent encounters related to the neuroma.

• Ensure the documentation explicitly states "neuroma of amputation stump" and does not specify the limb (e.g., upper, lower).
• If the specific extremity is documented (e.g., neuroma of right above-knee amputation stump), a more specific code from the T87.3 subcategory should be used.
• Always code any associated pain or other symptoms separately, if documented and clinically significant.
