Guinea worm disease

Parasitic infection by Guinea worm (Dracunculus medinensis) causing skin ulcers

What the rating means

Guinea worm disease is rated under diagnostic code 6320, "Parasitic diseases otherwise not specified," using the General Rating Formula for Infectious Diseases. When the disease is active, the rating is 100%. Once the active disease has resolved, the infection itself is rated at 0%. Any lasting health problems the infection caused are then rated separately under whichever body system they affect — for example, a joint, skin, or neurological condition — rather than continuing under this code. This means the total picture of your disability depends on what residual conditions remain after the infection clears and how those conditions are rated in their own body systems.

Evidence that helps

To support a 100% rating for active disease, medical records confirming a current, active guinea worm infection are central. Treating physician notes, laboratory findings, imaging, or hospital records that document the presence of the parasite and ongoing symptoms would reflect that active status. Once the disease has resolved, the evidence that matters most shifts to documentation of any lasting damage. Records showing specific residual conditions — such as joint damage, soft tissue injury, secondary infections, or other physical impairments — and their connection to the guinea worm infection help establish ratings under the appropriate body systems. Statements from you or people who know you describing how any remaining symptoms affect your work, movement, or daily activities can also help show the severity of those residual conditions.

Secondary conditions

Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
