Tuberculous Adenitis — VA Disability Rating (DC 7710)
Diagnostic Code 7710 · 38 CFR §4.117
What Is It?
Tuberculous adenitis is infection of the lymph nodes by Mycobacterium tuberculosis. The lymph nodes become swollen and may drain or form abscesses. Veterans may have been exposed to tuberculosis during deployments to regions where TB is endemic, in close quarters during barracks living, or through occupational exposure in military medical settings. The condition can be active (with ongoing infection) or inactive (previously treated but with residual lymph node damage). The VA rates differently based on whether the disease is active or inactive.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Active tuberculous adenitis requiring ongoing anti-tuberculosis treatment. |
| 30% | Inactive tuberculous adenitis with residual lymph node damage, scarring, or other chronic effects requiring ongoing monitoring. |
| 0% | History of tuberculous adenitis that has been fully treated with no active disease and no residual symptoms. |
Evidence Needed
TB testing results (skin test, blood test, cultures) are needed. Imaging showing affected lymph nodes helps document the extent. Treatment records for anti-tuberculosis medications are important. Service records showing deployment to TB-endemic areas or other exposure risk factors establish nexus. Follow-up records showing the current disease status (active vs. inactive) are needed for the rating.
C&P Exam Tips
Describe when you were diagnosed, the treatment received, and current symptoms. If the disease is inactive, describe any residual effects from the infection or treatment. If active, describe current symptoms and treatment burden.
How to File
File on VA Form 21-526EZ with DC 7710. Submit TB testing records, treatment documentation, and evidence of in-service exposure. A nexus opinion connecting the TB infection to service is recommended.
Common Mistakes
Not documenting the in-service exposure to TB — deployment to endemic areas, close-quarters living, or medical occupational exposure. Not distinguishing between active and inactive disease status can lead to the wrong rating level.
Frequently Asked Questions
Can TB adenitis be service-connected?
Yes. If you were exposed to TB during military service — through deployment to endemic regions, living in close quarters, or medical occupational exposure — and later developed tuberculous adenitis, the condition can be service-connected.
