5273
§ 4.71a Schedule of ratings—musculoskeletal system.

Heel or ankle bone malunion

The heel bone or ankle bone healed improperly after a fracture.

What the rating means

VA rates malunion of the os calcis (heel bone) or astragalus (ankle bone) under diagnostic code 5273. There are two possible ratings: 20 percent for marked deformity, and 10 percent for moderate deformity. The difference between the two levels comes down to how severe the deformity is. A more pronounced, visibly significant deformity of the heel or ankle bone falls under the marked category and receives the higher rating. A less severe but still measurable deformity falls under the moderate category and receives the lower rating. These are the only two percentage levels the regulation provides for this condition.

Evidence that helps

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.

Secondary conditions

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.
