Loss of the lower leg below the knee when a prosthesis cannot preserve natural knee movement.
To support a 60% rating under this code, the evidence needs to show two things: that you have a below-knee amputation, and that the residual limb cannot be improved by a prosthesis operated through natural knee action. Medical records documenting the amputation level are essential. Surgical reports, operative notes, and post-amputation clinic records help establish the anatomical facts. Prosthetic fitting records or a prosthetist's assessment showing why natural knee control cannot improve the prosthesis are directly relevant. A VA or private examination that describes the stump condition, any complications such as poor soft-tissue coverage, neuroma, or bone issues, and the resulting limitation on prosthetic function ties the clinical picture to the rating criteria. Statements from you describing how the amputation and prosthetic limitations affect your ability to walk, work, and carry out daily activities can also help complete the picture.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
