Secondary Condition Claim · VASRD 7101
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 Hypertension when it develops after Interstitial Nephritis.
Caused by kidney dysfunction
Primary condition · VASRD 7533
Interstitial Nephritis
Kidney inflammation that affects filtering ability, often caused by medications or infections.
Secondary condition · VASRD 7101
Hypertension
Hypertension is chronically elevated blood pressure that, left unmanaged, raises the risk of heart attack, stroke, and kidney disease. It's one of the most common VA claims, both filed directly and as a PACT Act presumptive condition for many Vietnam-era veterans exposed to Agent Orange.
The VA rates Hypertension the same way whether it's claimed directly or as secondary to Interstitial Nephritis — severity of Hypertension itself determines the percentage.
Example combined rating
30% Interstitial Nephritis + 20% Hypertension = 44%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 20% combine to 44%, not 50%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
