Secondary Condition Claim · VASRD 5252
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Limitation of Flexion of the Thigh (Hip) when it develops after Loss of Use of One Lower Extremity.
Overcompensation
Primary condition · VASRD 5104
Loss of Use of One Lower Extremity
Complete inability to use one leg due to paralysis, injury, or disease.
Secondary condition · VASRD 5252
Limitation of Flexion of the Thigh (Hip)
Hip flexion limitation makes it difficult to walk, sit, squat, or bend at the waist.
The VA rates Limitation of Flexion of the Thigh (Hip) the same way whether it's claimed directly or as secondary to Loss of Use of One Lower Extremity — severity of Limitation of Flexion of the Thigh (Hip) itself determines the percentage.
Example combined rating
100% Loss of Use of One Lower Extremity + 10% Limitation of Flexion of the Thigh (Hip) = 100%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 100% and 10% combine to 100%, not 110%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
