Kidney damage caused by viral infections such as HIV, Hepatitis B, or Hepatitis C.
Because the rating depends on GFR measured over time, the most direct evidence is lab reports showing GFR, estimated GFR, or creatinine-based GFR values recorded on at least three consecutive months within the past year, as calculated by a medical professional. For the 0% level, records showing a GFR of 60 to 89 alongside urinalysis results with RBC, WBC, or granular casts, imaging or pathology confirming structural kidney abnormalities, or urine albumin-to-creatinine ratio results of 30 mg/g or higher would support that level.
Records confirming the viral diagnosis—such as HIV, Hepatitis B, or Hepatitis C test results—help establish the connection between the infection and the kidney condition. Dialysis treatment records or a transplant evaluation showing you are an eligible recipient would support the 100% level. Statements from you or others describing how kidney disease affects your daily activities and work may also help VA understand the overall picture, but the GFR thresholds themselves must be documented in medical records.
