Diagnostic Code 7118 · 38 CFR §4.104
Angioneurotic edema (also called angioedema) is a condition that causes sudden, deep swelling beneath the skin, typically in the face, lips, tongue, throat, hands, feet, or genitals. Unlike regular allergic swelling, angioedema affects deeper tissue layers. It can be life-threatening when it involves the throat and restricts breathing. The condition can be hereditary, medication-related, or triggered by allergens or unknown causes. Veterans may develop angioedema from medication reactions, environmental exposures during service, or other service-related triggers.
