Diabetes insipidus

The VA rates Diabetes insipidus under Diagnostic Code 7909 at 10%, 30%. The minimum 10% rating requires: With persistent polyuria or requiring continuous hormonal therapy. The maximum 30% rating requires: For three months after initial diagnosis.

The VA rates Diabetes insipidus under Diagnostic Code (DC) 7909, governed by 38 CFR 38 CFR § 4.119. The diagnostic code establishes the specific rating tiers and severity criteria the VA examiner applies.

A 10% rating requires: With persistent polyuria or requiring continuous hormonal therapy. A 30% rating requires: For three months after initial diagnosis. The difference typically reflects the frequency, severity, or functional impact of the condition as documented in medical records and C&P examination findings.

Diabetes insipidus maxes at 30%, well below the single-disability TDIU threshold. However, combined with other service-connected disabilities, TDIU may be achievable under 38 CFR § 4.16. Focus on establishing secondary conditions to increase the combined rating.

The key evidence for Diabetes insipidus is documentation of how the condition affects daily functioning. Treatment records showing worsening symptoms, functional limitations documented by your provider, and buddy statements describing observable impact on daily life all strengthen the claim. A nexus letter from a qualified medical professional linking the current severity to service is essential for contested claims.

The C&P examiner uses a Endocrine System DBQ and evaluates your condition against the DC 7909 rating criteria. The examiner documents symptom frequency, severity, and functional impact. Bring all treatment records and describe your worst days, not your best — the VA rates on the full clinical picture across time, not a snapshot of one good day.
