Diagnostic Code 7502 · 38 CFR §4.115b
Chronic nephritis refers to ongoing inflammation of the kidney filtering units (glomeruli), which progressively impairs kidney function. This encompasses conditions like IgA nephropathy, membranous nephropathy, and other forms of glomerulonephritis. Veterans may develop chronic nephritis from infections acquired during service, toxic exposures damaging the kidneys, or autoimmune conditions triggered by service factors. The condition often progresses slowly over years.
| Rating | Criteria |
|---|---|
| 0% | Albumin and casts with history of acute nephritis, OR hypertension non-compensable under DC 7101. |
| 30% | Constant albuminuria with some edema, OR definite decrease in kidney function, OR hypertension at least 10% disabling under DC 7101. |
| 60% | Constant albuminuria with some edema, OR definite decrease in kidney function, OR hypertension at least 40% disabling under DC 7101. |
| 80% | Persistent edema and albuminuria with BUN 40 to 80 mg%, creatinine 4 to 8 mg%, or generalized poor health characterized by lethargy, weakness, anorexia, weight loss, or limitation of exertion. |
| 100% | Requiring regular dialysis, OR precluding more than sedentary activity from one or more of the symptoms in the 80% level. |
Kidney biopsy confirming the type of nephritis is the strongest evidence. Lab results showing protein in the urine, elevated creatinine, and decreased GFR demonstrate kidney function loss. Blood pressure records show associated hypertension. Treatment records including immunosuppressive medications document the severity. Service records connecting the onset or cause to military service establish eligibility.
Not always, but many forms are progressive. Some types respond well to treatment and stabilize. Others slowly worsen despite treatment. Regular monitoring with lab work is essential to track whether your condition is stable or declining, and worsening function supports a higher or increased rating.
Yes. Various chemicals, heavy metals, and other toxic substances can damage the kidney filtering units. Burn pit exposure, contaminated water (Camp Lejeune), industrial chemicals, and certain medications are all documented causes. If you were exposed to these during service, they can be the basis for service connection.
