VA Disability Rating for Angioneurotic Edema (DC 7118)
Diagnostic Code 7118 · 38 CFR §4.104
What Is It?
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.
Rating Criteria
| Rating | Criteria |
|---|---|
| 40% | Attacks without laryngeal involvement lasting one to seven days or longer and occurring more than eight times a year, or; attacks with laryngeal involvement of any duration occurring more than twice a year. |
| 20% | Attacks without laryngeal involvement lasting one to seven days and occurring five to eight times a year, or; attacks with laryngeal involvement of any duration occurring once or twice a year. |
| 10% | Attacks without laryngeal involvement lasting one to seven days and occurring two to four times a year. |
Evidence Needed
- Medical records documenting diagnosed angioedema episodes with dates, duration, and locations on the body
- Emergency room records from severe episodes, especially any involving throat swelling
- Allergy and immunology evaluation results
- Lab work including complement levels (C4, C1-INH) if hereditary angioedema is suspected
- A log or diary of episodes with details on frequency, triggers, and duration
- Service records showing the onset of episodes or exposure to triggering agents
C&P Exam Tips
- Keep a detailed diary of every episode — when it happened, where the swelling was, how long it lasted, and what triggered it
- Bring ER records from any severe episodes, especially those involving the throat
- If episodes are triggered by medications prescribed during service, document this connection
- Photos taken during active swelling episodes are very helpful evidence
- Make sure the examiner documents the frequency and average duration of your attacks
How to File
File on VA Form 21-526EZ with documentation of episodes, ER visits, and a nexus letter explaining the service connection. Include an episode log showing frequency and duration.
Common Mistakes
- Not tracking episodes between medical visits. Many episodes resolve before you see a doctor. Keep a detailed diary with photos so there is a record of every attack.
- Confusing angioedema with regular allergic reactions. Make sure your diagnosis specifically states angioedema, which involves deep tissue swelling, distinct from surface-level hives.
- Not documenting episode duration. The rating criteria depend on whether episodes last less than 24 hours, or one to three days. Track start and end times.
Frequently Asked Questions
What if my angioedema involves the throat?
Laryngeal involvement (throat swelling) is considered more serious. The rating criteria specifically distinguish between episodes with and without laryngeal involvement, and throat episodes may justify higher ratings or additional consideration.
Is hereditary angioedema ratable?
Hereditary angioedema may be ratable if it was aggravated during military service beyond its natural progression. You would need evidence that service worsened the condition.
Can angioedema from a medication reaction be service-connected?
If the medication was prescribed during service or for a service-connected condition, the resulting angioedema can be claimed as secondary.
