Secondary Condition Claim · VASRD 7101
Hypertension Secondary to Interstitial Nephritis
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.
Why Hypertension Is Linked to Interstitial Nephritis
Caused by kidney dysfunction
Primary condition · VASRD 7537
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.
Hypertension VA Rating Tiers
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.
| Rating | Criteria |
|---|---|
| 60% | Bottom blood-pressure number consistently at 130 or above |
| 40% | Bottom number consistently at 120 or above |
| 20% | Bottom number consistently at 110 or above, or top number consistently at 200 or above |
| 10% | Bottom number consistently at 100 or above, or top number consistently at 160 or above — or, if medication now controls it, a documented history of a bottom number predominantly 100 or more that requires continuous medication |
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.

Evidence for a Hypertension Secondary Claim
- •Blood pressure readings from primary care visits across multiple dates - this is the core evidence the rating schedule requires.

- How does a secondary Hypertension claim affect my combined VA rating?
- The VA doesn't add ratings together. Using the official combined-ratings formula (38 CFR 4.25): a 30% rating for Interstitial Nephritis combined with a 20% rating for Hypertension (example figures) produces a combined rating of 44%, not 50%.
