Kidney disease — including Chronic Kidney Disease (CKD) and End-Stage Renal Disease (ESRD) — affects a significant number of veterans, often as a downstream consequence of service-connected conditions like hypertension and diabetes. If your kidneys are failing because of a condition the VA already recognizes, you may be entitled to substantial additional compensation. This guide explains the secondary service connection pathways for kidney disease, the VA diagnostic codes that apply, how rating levels are determined, and what evidence you need to file a successful claim.
Under 38 CFR §3.310, a disability that is proximately due to or the result of a service-connected disease or injury is itself service-connected as a secondary condition. For kidney disease, the three most common secondary service connection pathways are:
You don't need to show that your kidneys were directly damaged in service. You only need to show that a service-connected condition caused or aggravated your kidney disease. If you have service-connected hypertension or diabetes, kidney disease is one of the most natural and well-documented secondary claims you can file.
Hypertensive nephrosclerosis — kidney damage caused by sustained high blood pressure — is one of the clearest secondary claims in VA benefits law. Elevated blood pressure damages the small blood vessels (glomeruli) in the kidneys over time, progressively reducing their ability to filter waste. This process is well-established in medical literature and routinely accepted by VA raters when properly documented.
To file CKD secondary to hypertension, you need:
The medical nexus here is often straightforward. If your hypertension predates your kidney disease by years and your nephrologist documents hypertensive nephropathy in your records, the connection is already established clinically. The nexus letter simply formalizes it for the VA.
Many veterans don't realize that hypertension itself can be claimed secondary to service-connected PTSD — and if the PTSD-caused hypertension then caused kidney disease, you have a chain of secondary conditions that ultimately connects your kidney disease to your service. See our guide on hypertension secondary to PTSD for details on building this chain claim.
Diabetic nephropathy develops in approximately 40% of people with diabetes and is the number one cause of kidney failure requiring dialysis in the United States. If you have service-connected diabetes — whether through direct service connection or through Agent Orange/herbicide presumptive service connection — and have developed kidney disease, this is one of the strongest possible secondary VA claims.
The progression from diabetes to CKD is well-documented: sustained high blood glucose levels damage the filtering units of the kidneys (glomeruli), leading to proteinuria (protein in urine), declining GFR, and eventually kidney failure. Your nephrologist's records likely already document "diabetic nephropathy" or "diabetic kidney disease" as the etiology of your CKD — this clinical documentation forms the basis of your nexus.
If you served in Vietnam, the Korean DMZ, Thailand (at certain locations), or were exposed to herbicide agents, Type II diabetes is presumptively service-connected. If you haven't yet filed for diabetes, do it now — then file kidney disease as a secondary. Our VA diabetes rating guide explains the process.
This pathway is less common but important for veterans with long-term service-connected musculoskeletal pain conditions. NSAIDs (non-steroidal anti-inflammatory drugs) are nephrotoxic — they reduce blood flow to the kidneys and, with chronic high-dose use, can cause permanent damage. Analgesic nephropathy is a recognized diagnosis when CKD develops in a patient with a long history of NSAID use.
To file CKD secondary to NSAID overuse, you need to establish:
VA pharmacy records can be invaluable here — request your VA medication history (available through MyHealtheVet or a VA records request) to document years of NSAID prescriptions for service-connected conditions.
The VA rates kidney conditions under 38 CFR Part 4, §4.115a and §4.115b, using Diagnostic Codes 7500 through 7530. The key codes for CKD and renal failure are:
| Diagnostic Code | Condition |
|---|---|
| DC 7500 | Kidney, chronic nephritis (glomerulonephritis) |
| DC 7501 | Kidney, nephrosis |
| DC 7502 | Nephrosclerosis (arteriolar — hypertensive nephropathy) |
| DC 7505 | Kidney, tuberculosis |
| DC 7508 | Nephrolithiasis (kidney stones) |
| DC 7509 | Hydronephrosis |
| DC 7511 | Cystitis, chronic |
| DC 7528 | Malignant neoplasms of the genitourinary system (100% while active; 100% for 1 year after completing treatment) |
| DC 7530 | Chronic renal disease (catch-all for CKD and renal failure) |
Most veterans with CKD secondary to hypertension or diabetes will be rated under DC 7502 (nephrosclerosis) or DC 7530 (chronic renal disease). The specific diagnostic code matters less than the rating level — the criteria are the same across most renal codes.
The VA rates renal conditions primarily based on renal function as measured by lab values: creatinine clearance (or estimated GFR — eGFR), serum creatinine, and whether the veteran requires dialysis. Under §4.115a, the rating formula for renal dysfunction is:
| Rating | Criteria |
|---|---|
| 100% | Requiring dialysis; OR persistent edema and albuminuria with BUN 40+ or creatinine 4+ mg/100 ml; or with generalized poor health (weakness, anorexia, weight loss, or limitation of exertion) |
| 80% | Persistent edema and albuminuria with BUN 40+ or creatinine 4+ mg/100 ml, or with generalized poor health characterized by pronounced anorexia, weakness and fatigability |
| 60% | Persistent edema and albuminuria; or BUN more than 40 mg/100 ml, or creatinine more than 4 mg/100 ml requiring diet restriction; or more than one episode of acute kidney injury in the past year |
| 30% | Persistent edema and albuminuria with BUN 21–40 or creatinine 2–4 mg/100 ml; or with some impairment of exertion |
| 0% | Albumin constant or recurring 1+ or 2+, with hyaline and granular casts or RBCs; or transient or slight edema; or elevated BUN less than 21 or creatinine less than 2 mg/100 ml |
While the VA's rating criteria use creatinine and BUN levels, your nephrologist likely tracks your kidney function using eGFR (estimated Glomerular Filtration Rate). Here's how CKD stages roughly correlate with VA ratings:
| CKD Stage | eGFR (mL/min/1.73m²) | Likely VA Rating Range |
|---|---|---|
| Stage 1–2 | 60–90+ | 0% (non-compensable) or 0% with symptoms |
| Stage 3 | 30–59 | 0–30% |
| Stage 4 | 15–29 | 30–60% |
| Stage 5 (ESRD) | <15 | 60–100% |
| ESRD on dialysis | N/A | 100% |
Your VA rating is based on your current lab values. If your kidney function has declined since your last C&P exam, submit updated creatinine, BUN, and GFR labs with your claim or rating increase request. Current labs showing worsening function can support a higher rating.
Veterans with End-Stage Renal Disease (ESRD) who require dialysis receive a 100% schedular rating under the renal diagnostic codes. But veterans with ESRD may also qualify for Special Monthly Compensation (SMC) under 38 U.S.C. §1114, which provides additional tax-free compensation beyond the standard 100% rate.
SMC eligibility for ESRD veterans typically arises when:

Veterans with service-connected hypertension or diabetes who haven't yet filed for CKD are leaving significant compensation on the table. Get free help identifying all your secondary conditions.
Start Your Free Secondary Claim Review →A nexus letter from your nephrologist is the most powerful piece of evidence in a kidney disease secondary claim. Your nephrologist is the specialist best positioned to connect your kidney diagnosis to your service-connected primary condition because they understand both the clinical presentation and the medical literature on nephropathy causation.
An effective nephrology nexus letter should include:
If your nephrologist is unfamiliar with VA nexus letters, a VA-accredited attorney can provide a template or guidance on what language the VA requires and connect you with physicians experienced in writing VA opinions.
After filing your claim, the VA will likely schedule a C&P examination to assess your renal function. The examiner will review your lab values, dialysis history if applicable, and any symptoms of renal insufficiency (fatigue, edema, nausea, decreased urine output). Bring your most recent nephrology visit notes, lab results, and a list of all symptoms. The examiner should also complete a DBQ (Disability Benefits Questionnaire) for renal conditions.
