Chronic Nephritis — VA Disability Rating (DC 7502)

Diagnostic Code 7502 · 38 CFR §4.115b

What Is It?

Chronic nephritis is long-standing inflammation of the kidney's filtering units. It follows an acute glomerulonephritis that never fully cleared, an autoimmune process, or years of another disease working on the kidney, and it announces itself quietly — protein or blood in the urine, rising blood pressure, swelling in the ankles and around the eyes, fatigue — long before any number looks alarming. Under 38 CFR §4.115b, DC 7502 carries no criteria of its own. The entry is three words: rate as renal dysfunction. That matters more than it sounds, because the renal dysfunction criteria in 38 CFR §4.115a were rewritten effective November 14, 2021. The old formula asked about constant albuminuria, some edema, definite decrease in kidney function, BUN of 40 to 80 mg percent, and creatinine of 4 to 8 mg percent. The current formula asks for a number: your glomerular filtration rate, in mL/min/1.73 m2, sustained for at least 3 consecutive months during the past 12 months. Guides written before late 2021 still show the old table, and a veteran who prepares against it will bring the wrong evidence to the examination. One more rule sits on top of this code: 38 CFR §4.115 provides that separate ratings are not to be assigned for disability from disease of the heart and any form of nephritis, because of the close interrelationship of cardiovascular disabilities — with named exceptions when a kidney is absent or when regular dialysis has become necessary.

Rating Criteria

Evidence Needed

The criteria are built on one number repeated over time, so the evidence has to be a series rather than a snapshot. Pull every creatinine result with its calculated GFR going back at least two years and lay them out by date; the regulation asks for the level to have held for at least 3 consecutive months during the past 12, and a single low reading will not meet it. A note under the section provides that GFR, estimated GFR, and creatinine-based approximations of GFR are accepted for evaluation purposes when determined to be appropriate and calculated by a medical professional, so ordinary lab-reported eGFR values are usable. For the 0 percent level, urinalysis showing red cell, white cell, or granular casts, imaging showing structural abnormality, or an albumin/creatinine ratio of 30 mg/g or higher is what is being asked for — so make sure a urine albumin/creatinine ratio has actually been ordered, since it often has not. Add the kidney biopsy report if one exists, the nephrology notes, and the blood pressure record.

C&P Exam Tips

Bring the lab series printed out, in date order, with the GFR column marked. This is the rare examination where the numbers are the case, and handing the examiner a clean chronology is more useful than any description of symptoms. If your GFR fluctuates, say so and point to the three-month stretches, because the criteria are written around a level sustained for at least 3 consecutive months rather than a best or worst day. Ask specifically whether a urine albumin/creatinine ratio is being collected; it appears by name in the criteria and is routinely skipped. Describe the daily reality as well — swelling, fatigue, nausea, appetite loss, itching, muscle cramps, how many hours you can work — since those support the broader picture even though they are not the measured criteria. If dialysis has been discussed or you have been evaluated for transplant listing, say so directly, because both appear in the 100 percent criterion.

How to File

File on VA Form 21-526EZ naming chronic nephritis under DC 7502, and state that you are asking for evaluation under the renal dysfunction criteria of 38 CFR §4.115a as revised effective November 14, 2021. Attach the GFR series rather than a single result, the urinalysis showing casts or protein, a urine albumin/creatinine ratio, the biopsy report if one exists, and the nephrology notes. If the nephritis followed a service-connected infection, a documented in-service illness, or exposure, say so and cite the record by date. If it is secondary to service-connected diabetes, hypertension, or lupus, file under 38 CFR §3.310 and name the primary condition. Before claiming heart disease alongside it, read 38 CFR §4.115 — separate ratings for heart disease and nephritis are restricted, with specific exceptions.

Common Mistakes

The largest mistake right now is preparing against the pre-2021 criteria. Veterans still arrive with evidence organized around albuminuria, edema, BUN, and creatinine in mg percent because that is what most published guides show, and none of those terms appear in the current formula. The second is submitting one low GFR reading, when the regulation asks for the level to have been sustained for at least 3 consecutive months during the past 12. The third is never having a urine albumin/creatinine ratio drawn; it is named in the 0 percent criterion and it is frequently the missing piece. The fourth is claiming a separate evaluation for heart disease without reading 38 CFR §4.115, which restricts separate ratings for heart disease and nephritis except where a kidney is absent or regular dialysis has become necessary — a rule worth understanding before it surprises you in a decision.

Frequently Asked Questions

What changed in the kidney criteria in 2021?

VA replaced the descriptive renal dysfunction formula with laboratory values. The final rule took effect November 14, 2021 and swapped terms like constant albuminuria, some edema, and definite decrease in kidney function for glomerular filtration rate ranges and an albumin/creatinine ratio threshold. The rating tiers themselves stayed at 0, 30, 60, 80, and 100 percent. The practical effect is that the evaluation now rests on numbers a lab produces, which makes the outcome more predictable and makes an incomplete lab record more damaging.

Will my old rating be reduced because the criteria changed?

A change in the rating schedule does not by itself reduce an existing evaluation. Any reduction has to go through the procedural protections in 38 CFR §3.105(e), which require notice and an opportunity to respond, and it has to be supported by an examination showing sustained improvement. If you were evaluated under the pre-2021 criteria and receive a proposed reduction, read the proposal against those requirements carefully and consider getting help from an accredited representative before the response window closes.

My GFR moves around. Which reading counts?

The criteria are written around a level held for at least 3 consecutive months during the past 12-month period, so the question is not your best or worst value but whether a range was sustained. Print the full series by date and look for stretches of three months or more at a given level. If your values swing because of dehydration, medication, or an acute illness, ask your nephrologist to note that in the record, because an unexplained outlier can otherwise be read as your baseline.

Does protein in my urine still matter?

Yes, but in a specific form. The current criteria do not use the term albuminuria; they use an albumin/creatinine ratio of 30 mg/g or greater, combined with a GFR of 60 to 89, as one route to the 0 percent level. So ask for that specific test by name. Casts in the urine — red blood cell, white blood cell, or granular — serve the same function at that level, as does documented structural abnormality on imaging.

Can I be rated for both nephritis and heart disease?

Usually not, and the restriction is explicit. 38 CFR §4.115 states that separate ratings are not to be assigned for disability from disease of the heart and any form of nephritis, because of the close interrelationship of cardiovascular disabilities. There are two named exceptions: if absence of a kidney is the sole renal disability, the absent kidney and any hypertension or heart disease are separately rated; and if chronic renal disease has progressed to the point where regular dialysis is required, any coexisting hypertension or heart disease is separately rated.
