Diagnostic Code 6310 · 38 CFR §4.88b
Syphilis and other treponema infections are bacterial diseases that can affect multiple organ systems if untreated. Syphilis progresses through stages: primary (chancre sore), secondary (rash, systemic symptoms), latent (no symptoms but infection persists), and tertiary (serious organ damage years later). Under DC 6310, the VA does not rate the infection itself but instead rates any residual disability under the appropriate body system codes. The regulation specifically references cardiovascular codes (DC 7004), neurological codes (DC 8013, 8014, 8015), and eye and ear conditions.
| Rating | Criteria |
|---|---|
| 0% | There is no standalone percentage rating under DC 6310. All residual disabilities are rated under the appropriate body system. Nervous system damage is rated under neurological codes (such as DC 8013 for cerebrospinal syphilis), vascular damage under cardiovascular codes (such as DC 7004), and eye or ear conditions under those respective systems. |
Serological testing confirming syphilis (RPR, VDRL, FTA-ABS). Service medical records. Neurological examination and cerebrospinal fluid analysis if neurosyphilis suspected. Echocardiogram for cardiovascular involvement. Eye examination. Audiological testing. Documentation of treatment timeline.
The VA rates syphilis entirely by its residual effects on specific body systems. This approach can actually result in higher combined ratings because you get separate ratings for each damaged system.
Neurosyphilis occurs when bacteria invade the nervous system, causing cognitive decline, balance problems, and pain syndromes. It is rated under neurological codes, particularly DC 8013.
Yes. Tertiary syphilis can develop 10 to 30 years after the initial infection if inadequately treated.
