Chronic leg symptoms such as swelling, pain, and skin changes that develop after a blood clot damages leg veins.
Medical records documenting the findings present in your affected extremity are central to establishing the correct rating level. Records that show the presence and persistence of edema — and whether elevation or compression hosiery relieves it — help distinguish lower rating levels from higher ones. Physician notes or imaging that confirm subcutaneous induration, stasis pigmentation, or eczema support the 40% and 60% levels. Documentation of active or persistent ulceration is key to the 60% level. At the highest level, records must show massive board-like edema together with pain that is constant even while you are at rest.
Physical examination findings from VA or private providers are particularly useful, as they can capture the character and extent of swelling, skin changes, and ulcers. Your own statements, and statements from those who observe you daily, can describe how symptoms affect your ability to stand, walk, or carry out daily activities. If more than one leg is affected, records clearly identifying findings in each extremity separately will matter for how VA evaluates and combines the ratings.
