Amputation of the arm at or above the shoulder joint.
Medical records that clearly describe the level and extent of your amputation are central to establishing the correct rating. Operative reports, pathology reports, and discharge summaries are particularly useful because they document exactly which bones were removed. A report that identifies removal of the humerus together with any portion of the scapula, clavicle, or ribs would support the forequarter level. A report showing removal of the humerus only, at the shoulder joint, would support the disarticulation level.
Imaging studies such as X-rays or CT scans can confirm the current anatomy if operative records are unavailable or incomplete. A VA or private examination that documents the residual limb and remaining shoulder structure can also help show which bones are absent. Statements from you or people who know you describing how the amputation affects your daily activities and work may support the overall picture, though the anatomical level itself is determined by the medical findings.
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.
