Secondary Condition Claim · VASRD 5016
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 Osteoporosis with Pathological Fractures when it develops after Ankylosing Spondylitis.
Chronic inflammation increases bone loss risk
Primary condition · VASRD 5004
Ankylosing Spondylitis
A chronic inflammatory disease causing spine fusion and pain.
Secondary condition · VASRD 5016
Osteoporosis with Pathological Fractures
A disease causing bones to become weak and prone to breaking.
The VA rates Osteoporosis with Pathological Fractures the same way whether it's claimed directly or as secondary to Ankylosing Spondylitis — severity of Osteoporosis with Pathological Fractures itself determines the percentage.
Example combined rating
40% Ankylosing Spondylitis + 30% Osteoporosis with Pathological Fractures = 58%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 30% combine to 58%, not 70%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
