VA Disability Rating for Toxic nephropathy (DC 7535)
DC 7535 covers toxic nephropathy, kidney damage from a toxic substance such as a drug or an antibiotic. The VA rates it as renal dysfunction, from 0% up to 100% by the glomerular filtration rate (GFR) sustained for at least 3 consecutive months in the past year, by recurrent urine casts or persistent proteinuria at a near-normal GFR, and by the need for regular dialysis or eligibility for a kidney transplant (38 CFR 4.115a and 4.115b). What caused the exposure is a service-connection question decided on your records, not part of the rating.
