VA Disability Rating for Parasitic Diseases (DC 6320)
Diagnostic Code 6320 · 38 CFR §4.88b
What Is It?
This is a catch-all for parasitic infections without their own diagnostic code. The VA uses the General Rating Formula: active disease at 100 percent, and residual organ damage rated under appropriate body system codes.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Active parasitic infection confirmed by lab testing with symptoms requiring treatment. |
| 0% | Successfully treated. Residual organ damage is rated under affected body system codes. |
Evidence Needed
Stool examination, blood tests, or biopsy confirming the parasite. Deployment records to endemic areas. Treatment records. Documentation of chronic symptoms. Follow-up testing.
C&P Exam Tips
Identify the specific parasite. Bring deployment records. Describe exposure conditions. Report chronic GI or other symptoms. Mention if you have had recurrent episodes.
How to File
File under DC 6320 with lab confirmation and deployment records. File residual organ damage separately. Do not assume old infections have resolved without testing.
Common Mistakes
Common mistakes include not specifying the exact parasite, assuming the infection resolved without testing, not claiming GI damage separately, and overlooking parasites that persist for decades.
Frequently Asked Questions
Can parasitic infections persist for years?
Yes. Many parasites, particularly Strongyloides stercoralis, can maintain chronic infections for decades through auto-infection.
What if I cannot identify the specific parasite?
While identifying the organism strengthens the claim, the VA can rate based on documented symptoms, exposure history, and treatment response.
