What to Expect During Your Exam

Exam Overview

To document the current severity of chronic nephritis and its impact on renal function so that VA can assign a disability rating under DC 7502, which directs rating as renal dysfunction per 38 CFR - 4.115a.

What the examiner evaluates:

  • Current diagnosis and ICD code for chronic nephritis
  • History, onset, and course of the condition including any in-service event, injury, or illness
  • Current symptoms including edema, hypertension, fatigue, nausea, and urinary changes
  • Lab results: creatinine, BUN, GFR (eGFR), urinalysis findings including casts (RBC, WBC, granular), proteinuria (ACR - 30 mg/g)
  • Current renal function stage (CKD staging based on eGFR)
  • Treatment history: diet therapy, drug therapy, dialysis, kidney transplant, invasive/non-invasive procedures
  • Hospitalizations related to renal disease
  • Complications: hypertension, anemia of chronic kidney disease, electrolyte imbalances, cardiovascular effects
  • Functional impact on daily activities and employment
  • Any comorbid kidney or genitourinary conditions (pyelonephritis, hydronephrosis, nephrolithiasis, etc.)
  • Whether condition requires continuous intensive management

Exam may be conducted in person at a VA facility, community care clinic, or via telehealth. If conducted via telehealth, the examiner must note how the exam was conducted. Bring all lab reports and imaging studies to the exam. You have the right to request that the exam be recorded in most states.

Typical duration: 30-45 minutes

Estimated Glomerular Filtration Rate (eGFR)

How well the kidneys filter waste from the blood; the primary measure of renal function used to determine CKD stage and VA rating level under 38 CFR - 4.115a.

What to expect:

The examiner will review your most recent serum creatinine lab results and calculate or reference your eGFR. The examiner may order labs if recent results are unavailable. Bring all recent lab work.

Key thresholds:

  • eGFR - 60 mL/min/1.73m- — Generally reflects preserved or mildly reduced renal function; rating based on other criteria such as proteinuria, casts, or symptomatic burden. Consistent with lower rating levels under renal dysfunction criteria.
  • eGFR 30-59 mL/min/1.73m- — Moderately reduced kidney function (CKD Stage 3); supports higher disability ratings under renal dysfunction criteria when combined with other findings.
  • eGFR 15-29 mL/min/1.73m- — Severely reduced kidney function (CKD Stage 4); associated with significant renal dysfunction and higher disability rating potential.
  • eGFR < 15 mL/min/1.73m- — Kidney failure (CKD Stage 5 / ESRD); may support 100% rating if requiring dialysis. Evaluate under DC 7530 if on regular dialysis.

Tips:

  • Request your most recent lab results from your treating nephrologist or primary care provider before the exam.
  • If your eGFR fluctuates, bring labs showing the range over the past 12 months - the rater considers the overall picture.
  • Do not reschedule the exam on a 'good day' after aggressive hydration; your typical daily function is what matters.
  • If labs have not been drawn recently, ask the examiner to order them at the time of the C&P exam.

Pain considerations: Chronic nephritis is not typically a pain-forward condition; however, flank pain, headache from hypertension, and fatigue are real symptoms. Accurately describe any pain associated with episodes of acute exacerbation.

Urinalysis with Microscopy (Urine Casts and Proteinuria)

Presence of RBC casts, WBC casts, granular casts, and albumin-to-creatinine ratio (ACR - 30 mg/g) - key markers of glomerular and tubular injury in chronic nephritis. These are specific DBQ fields the examiner must address.

What to expect:

The examiner will review urinalysis results. RBC casts indicate glomerular bleeding (hallmark of glomerulonephritis/nephritis). WBC casts suggest interstitial inflammation. Granular casts indicate tubular damage. Persistent proteinuria (ACR - 30 mg/g) is a major criterion.

Key thresholds:

  • ACR - 30 mg/g (microalbuminuria or macroalbuminuria) — A required checkbox in the DBQ; confirms active renal involvement and contributes to eligibility for higher rating tiers under renal dysfunction criteria.
  • Presence of RBC casts — Pathognomonic for glomerulonephritis; strongly supports the diagnosis of chronic nephritis and documents active disease.
  • Presence of WBC casts — Suggests interstitial nephritis or pyelonephritis component; supports diagnosis and higher severity rating.
  • Presence of granular casts — Indicates tubular damage and chronic renal parenchymal disease; supports more severe renal dysfunction rating.

Tips:

  • Bring copies of all recent urinalysis results, including 24-hour urine protein collections if performed.
  • If you have had multiple urinalyses, bring them all - even a single positive result for casts is significant.
  • Ask your treating nephrologist to document cast findings in a letter if your most recent labs do not reflect your typical disease activity.

Pain considerations: Hematuria (blood in urine) may be associated with discomfort or anxiety. Accurately describe any episodes of gross hematuria and their frequency.

Blood Pressure Measurement

Hypertension is a major complication and symptom of chronic nephritis. The examiner will record your blood pressure and assess whether renal hypertension is present and being treated.

What to expect:

Blood pressure will be taken during the physical examination component. Hypertension secondary to chronic nephritis may be separately ratable or rated as part of the renal dysfunction picture. Document all antihypertensive medications you take.

Key thresholds:

  • Systolic - 140 or Diastolic - 90 on medication — Indicates poorly controlled or treatment-resistant hypertension; may support a separate rating under DC 7101 for hypertension secondary to nephritis.
  • Requiring multiple antihypertensive medications — Indicates medication burden and severity; documents continuous intensive management requirement.

Tips:

  • Do not take extra blood pressure medication before the exam to artificially lower your reading. The examiner needs to see your typical, medicated blood pressure.
  • Bring a list of all antihypertensive medications with dosages.
  • If you have home blood pressure logs showing elevated readings, bring them.
  • Hypertension caused by chronic nephritis may be separately ratable under DC 7101 - mention it explicitly.

Pain considerations: Hypertensive headaches are real symptoms. Describe frequency, severity, and impact on daily function.

BUN (Blood Urea Nitrogen) and Serum Creatinine

Waste products that accumulate when kidneys fail to filter effectively. Elevated BUN and creatinine confirm impaired renal function and are used alongside eGFR to stage kidney disease.

What to expect:

The examiner will review recent metabolic panel results. Bring your most recent comprehensive metabolic panel (CMP). If elevated, these values support higher-level disability ratings.

Key thresholds:

  • Serum creatinine > 1.5 mg/dL (males) or > 1.2 mg/dL (females) — Indicates reduced renal clearance; supports documentation of renal dysfunction.
  • BUN > 20 mg/dL in context of low eGFR — Confirms azotemia; associated with more significant renal dysfunction ratings.

Tips:

  • Bring the most recent CMP from your nephrologist or VA lab.
  • If values fluctuate, provide a series of labs to show the trend - declining function over time is important documentation.

Pain considerations: Elevated BUN can cause uremic symptoms including nausea, fatigue, brain fog, and decreased appetite. Describe all of these symptoms to the examiner.

Estimate

Rating Criteria Breakdown

100% End-stage renal disease or requirement for regular dialysis. ...

End-stage renal disease or requirement for regular dialysis. Complete or near-complete renal failure. Renal transplant status. eGFR < 15 mL/min/1.73m- (CKD Stage 5). If on regular dialysis, evaluate under DC 7530. Kidney transplant rated at 100% for one year post-transplant, then as residuals.

Key Symptoms

  • eGFR < 15 mL/min/1.73m- (kidney failure)
  • Requirement for regular hemodialysis or peritoneal dialysis
  • Kidney transplant recipient
  • Uremia with multi-system involvement
  • Complete inability to perform substantial gainful employment
  • Severe anemia, hypertension, fluid overload
  • Dependence on dialysis or post-transplant immunosuppression
  • Severely impaired functional capacity

CFR: Under 38 CFR - 4.115b DC 7530, chronic renal disease requiring regular dialysis is rated as renal dysfunction and typically warrants a 100% evaluation. DC 7502 (chronic nephritis) progressing to ESRD is rated as renal dysfunction under - 4.115a at the highest level. Kidney transplant under DC 7501 is rated 100% for one year post-transplant.

60% Renal dysfunction with significantly reduced kidney function ...

Renal dysfunction with significantly reduced kidney function, consistent with CKD Stage 3b-4. Requires continuous intensive management. Multiple medications, possible hospitalizations, and significant functional impairment. eGFR in the range of 15-44 mL/min/1.73m-.

Key Symptoms

  • Significantly reduced eGFR (approximately 15-44 mL/min/1.73m-)
  • Marked proteinuria and hematuria with casts
  • Requiring continuous intensive medical management
  • Anemia of chronic kidney disease requiring treatment
  • Significant hypertension requiring multiple medications
  • Peripheral edema
  • Fatigue severely limiting daily activities and work capacity
  • Nausea, decreased appetite, uremic symptoms
  • Electrolyte imbalances requiring management
  • Hospitalizations for exacerbations

CFR: Under 38 CFR - 4.115a renal dysfunction criteria, this level reflects severe impairment of kidney function requiring continuous management. The DBQ field for 'continuous intensive management required' (field 224) is a key marker at this level. Functional impact on work and daily activities must be thoroughly documented.

30% Renal dysfunction with persistent proteinuria, elevated crea ...

Renal dysfunction with persistent proteinuria, elevated creatinine, or reduced eGFR consistent with CKD Stage 2-3a. Condition requires ongoing medical management including diet and/or medication therapy. Lab findings document chronic kidney involvement.

Key Symptoms

  • Persistent proteinuria (ACR - 30 mg/g)
  • Mildly to moderately reduced eGFR (approximately 45-59 mL/min/1.73m-)
  • Mild elevation of creatinine and/or BUN
  • Requiring diet therapy and/or drug therapy
  • Urinary casts present on microscopy
  • Fatigue and mild edema
  • Hypertension requiring medication

CFR: Under 38 CFR - 4.115a, renal dysfunction rated at this level reflects documented laboratory abnormalities requiring active medical management. Chronic nephritis (DC 7502) directs rating as renal dysfunction, so all findings that support higher-level renal dysfunction criteria apply.

0% Renal dysfunction is present but does not meet the threshold ...

Renal dysfunction is present but does not meet the threshold for a compensable rating under 38 CFR - 4.115a. Condition is diagnosed and service-connected but symptoms are minimal and lab values are near normal.

Key Symptoms

  • Diagnosis confirmed but eGFR within normal or near-normal range
  • Mild or no proteinuria
  • No significant elevation of creatinine or BUN
  • No required treatment beyond monitoring
  • No functional impairment

CFR: Under 38 CFR - 4.115a, renal dysfunction ratings begin at the lowest compensable level when lab abnormalities and symptoms are present but mild. A 0% rating indicates service connection is established but current severity does not yet meet minimum compensable criteria.

How to Describe Your Symptoms

Fatigue and Functional Limitation

How to describe:

Describe fatigue as it affects your ability to perform daily activities, work, household tasks, and social activities. Quantify how many hours per day you can be active before fatigue sets in. Note whether fatigue is constant or episodic.

Worst-day example:

“On my worst days, I am so fatigued that I cannot get out of bed for more than a few hours. I cannot drive, prepare meals, or perform basic household tasks. I need to rest after any minor exertion such as showering or walking to my mailbox. This level of fatigue occurs approximately [X] days per week.”

What the examiner listens for:

The examiner needs to understand how fatigue limits your occupational and daily functioning. Statements connecting fatigue to inability to maintain employment or perform activities of daily living directly support higher-level renal dysfunction ratings.

Understatements to avoid:

Do not say 'I get a little tired' if your fatigue significantly limits your activities. Do not minimize fatigue because you have learned to cope with it. Describe your actual functional capacity accurately.

Edema (Fluid Retention and Swelling)

How to describe:

Describe which body parts swell, how severe the swelling becomes, how often it occurs, and what you must do to manage it (elevating legs, wearing compression stockings, taking diuretics). Note whether swelling limits walking, wearing shoes, or working.

Worst-day example:

“On my worst days, my ankles and lower legs swell so severely that I cannot wear regular shoes and must elevate my legs for several hours. My abdomen becomes distended and uncomfortable. Even with diuretic medication taken daily, I still experience significant swelling [X] days per week.”

What the examiner listens for:

Peripheral edema is a hallmark sign of nephrotic syndrome and severe renal dysfunction. The examiner will note whether edema is present and whether it requires treatment. Documenting treatment-resistant or medication-dependent edema supports higher disability ratings.

Understatements to avoid:

Do not omit edema because it is 'normal for you.' Do not fail to mention that you require diuretics or other interventions to manage swelling.

Urinary Symptoms

How to describe:

Describe changes in urine output (polyuria, oliguria), foamy or frothy urine (proteinuria), blood in urine (hematuria), frequency, urgency, nocturia (waking at night to urinate), and any voiding difficulties. Quantify how often these occur.

Worst-day example:

“On my worst days, I urinate very frequently - up to [X] times during the night - which severely disrupts my sleep. My urine appears foamy, which my doctor has told me is due to protein in my urine. I have had episodes where my urine appeared dark or blood-tinged, occurring approximately [X] times per month.”

What the examiner listens for:

The DBQ specifically captures voiding dysfunction symptoms. Nocturia, hematuria, proteinuria-related foamy urine, and frequency all feed into the overall severity picture. These are key fields the examiner must document.

Understatements to avoid:

Do not omit nocturia - it has a major impact on sleep quality and next-day function. Do not fail to mention foamy urine if present; it is a direct indicator of proteinuria that the examiner needs to document.

Nausea, Appetite Loss, and Uremic Symptoms

How to describe:

Describe nausea, vomiting, decreased appetite, metallic taste in the mouth, and cognitive effects such as difficulty concentrating or 'brain fog.' Quantify how often these symptoms occur and whether they affect your ability to eat, work, or function.

Worst-day example:

“On my worst days, I feel persistently nauseated and cannot eat more than a few bites at meals. I have experienced unintentional weight loss of [X] pounds over the past year. I have a constant metallic taste in my mouth and difficulty concentrating, which makes it impossible for me to perform my job duties.”

What the examiner listens for:

Uremic symptoms indicate significant accumulation of waste products due to impaired kidney filtration. These symptoms are consistent with advanced renal dysfunction and support higher disability ratings. The examiner needs to document them as part of the functional impact assessment.

Understatements to avoid:

Do not fail to mention cognitive effects of uremia. Do not say you have adjusted to reduced appetite without noting the functional impact of weight loss and nutritional deficiency.

Hypertension and Cardiovascular Effects

How to describe:

Describe your blood pressure history, how many medications you take to control it, whether it remains poorly controlled despite medication, and any related symptoms such as headaches, dizziness, or shortness of breath.

Worst-day example:

“Despite taking [X] blood pressure medications daily, my blood pressure regularly reads above [X/X] mmHg at home. On my worst days, I experience severe headaches and dizziness that force me to lie down. I have had [X] hypertensive urgency episodes in the past year requiring emergency or urgent care.”

What the examiner listens for:

Renal hypertension is a direct complication of chronic nephritis. The examiner will document whether it is present and being treated. Poorly controlled hypertension on multiple medications supports both a higher renal dysfunction rating and a potentially separate rating under DC 7101.

Understatements to avoid:

Do not say your blood pressure is 'fine' if you are taking medications to control it. The medications are the reason it is controlled - without them it would not be fine. Always mention every antihypertensive medication you take.

Treatment Burden and Continuous Management

How to describe:

Describe every treatment you undergo: dietary restrictions (low-protein, low-sodium, low-potassium, fluid restriction), all medications and their side effects, dialysis schedule if applicable, frequency of lab draws and physician visits, and any invasive procedures.

Worst-day example:

“I attend dialysis three times per week, each session lasting approximately four hours, which prevents me from working and exhausts me for the remainder of those days. I take [X] medications daily including immunosuppressants with significant side effects. I have dietary restrictions that require me to avoid [list foods] and carefully measure all fluid intake.”

What the examiner listens for:

The DBQ field for 'continuous intensive management required' is a critical checkbox that supports higher-level ratings. Documenting the full scope of your treatment burden - medications, diet, procedures, hospitalizations - directly informs whether this field is checked.

Understatements to avoid:

Do not underestimate the burden of dietary restrictions, medication regimens, or frequent medical appointments. These all constitute management of your condition and must be accurately reported.
