Veterans rated for Papillary necrosis may qualify for TDIU if the condition — alone or in combination with other service-connected disabilities — prevents substantially gainful employment. A single disability rated at 60% or higher (or multiple disabilities combining to 70%, with one at 40%) can support a TDIU claim under 38 CFR § 4.16.

Service connection for Papillary necrosis requires three elements: (1) a current diagnosis of the condition, (2) an in-service event, injury, or disease, and (3) a medical nexus linking the current diagnosis to that in-service occurrence. A nexus letter from a treating or independent medical examiner is the most reliable nexus evidence.

A Compensation & Pension (C&P) exam for Papillary necrosis uses a Disability Benefits Questionnaire (DBQ) specific to the body system involved. The examiner documents the frequency, severity, and functional impact of your symptoms. Bring all relevant treatment records and be prepared to describe your worst-day symptoms — the examiner rates your condition based on the full clinical picture, not a single visit.
