Secondary Condition Claim · VASRD 7530
Chronic renal disease 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 Chronic renal disease when it develops after Interstitial Nephritis.
Why Chronic renal disease Is Linked to Interstitial Nephritis
Reduced erythropoietin
Primary condition · VASRD 7537
Interstitial Nephritis
Kidney inflammation that affects filtering ability, often caused by medications or infections.
Secondary condition · VASRD 7530
Chronic renal disease
Chronic renal disease is long-term, progressive damage to the kidneys' ability to filter waste from the blood. DC 7530 carries no criteria of its own — the schedule directs "Rate as renal dysfunction" — so the evaluation comes from the § 4.115a table, which is graded by glomerular filtration rate. Each band has to hold for at least 3 consecutive months during the past 12 months, and requiring regular routine dialysis or being an eligible kidney transplant recipient reaches 100 percent on its own.
Chronic renal disease VA Rating Tiers
The VA rates Chronic renal disease the same way whether it's claimed directly or as secondary to Interstitial Nephritis — severity of Chronic renal disease itself determines the percentage.
Example combined rating
30% Interstitial Nephritis + 80% Chronic renal disease = 86%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 80% combine to 86%, not 110%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Chronic renal disease Secondary Claim
- •Serial GFR or eGFR results with dates, spanning at least 3 consecutive months within the past 12 months.
- •Dialysis records showing the treatment is regular and routine, or documentation of eligibility as a kidney transplant recipient — each reaches 100 percent independently.
- •An albumin/creatinine ratio result, urinalysis reporting red blood cell, white blood cell or granular casts, and imaging of any structural kidney abnormality, which are the findings named at the 0 percent level.
- •Nephrology records documenting the diagnosis and its course.
Common questions about Chronic renal disease secondary to Interstitial Nephritis
- Can Chronic renal disease be service-connected as secondary to Interstitial Nephritis?
- Yes. Under 38 CFR § 3.310, a condition that is caused or aggravated by an already service-connected disability can be granted secondary service connection. Reduced erythropoietin You'll need a current Chronic renal disease diagnosis and a medical nexus opinion linking it to your service-connected Interstitial Nephriti…
- What VA rating can I get for Chronic renal disease as a secondary condition?
- Chronic renal disease is rated under VASRD diagnostic code 7530 using the same criteria whether it's a direct or secondary claim: possible ratings are 100%, 80%, 60%, 30%, 0%. The rating depends on the severity of Chronic renal disease itself, not on the severity of Interstitial Nephritis.
- How does a secondary Chronic renal disease 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 80% rating for Chronic renal disease (example figures) produces a combined rating of 86%, not 110%. Approving Chronic renal disease as secondary still typically raises…
- What evidence do I need to service-connect Chronic renal disease as secondary to Interstitial Nephritis?
- Strong evidence for the underlying Chronic renal disease diagnosis includes: Serial GFR or eGFR results with dates, spanning at least 3 consecutive months within the past 12 months.; Dialysis records showing the treatment is regular and routine, or documentation of eligibility as a kidney transplant recipient — each r…
