Long-term inflammation of the kidneys that gradually impairs their ability to filter waste from the blood.
Because chronic nephritis is rated as renal dysfunction, your medical records should document GFR measurements taken over time. VA accepts GFR, estimated GFR (eGFR), and creatinine-based approximations of GFR when calculated by a medical professional. Lab results showing GFR readings across at least 3 consecutive months within the past 12 months are central to establishing the correct rating level.
For the 0% level, records should show GFR in the 60 to 89 range alongside urinalysis results documenting recurrent RBC, WBC, or granular casts, imaging or biopsy findings showing structural kidney abnormalities, or lab results showing an albumin/creatinine ratio of 30 mg/g or higher — again across at least 3 consecutive months.
If your condition also involves dialysis or a kidney transplant, documentation from your treatment team confirming those facts supports the 100% level. Nephrology records, hospital treatment notes, and dialysis logs all help show the duration and severity the rating formula requires.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
