The heel bone or ankle bone healed improperly after a fracture.
To support a rating at either level, medical evidence needs to show the degree of deformity in your heel or ankle bone resulting from a malunion. Imaging studies such as X-rays are central to this, because they can document the angle, displacement, or structural irregularity of the bone as it healed out of normal alignment. A VA or private examination that describes the deformity as marked or moderate is directly tied to the rating criteria. Physical examination findings noting visible bony prominence, abnormal contour, or malalignment also support the severity determination. Statements from you or people who know you, describing how the deformity affects your ability to walk, stand, or carry out daily activities, can help paint a complete picture of how severe the condition is in practice.
