Thrombotic Thrombocytopenic Purpura (TTP) Residuals

DC 7705Hematologic/Lymphatic38 CFR 4.117, DC 7705

A rare blood disorder where small blood clots form throughout your body, using up your platelets and causing damage to organs like the brain and kidneys. The VA rates TTP residuals based on how often the disease comes back, what organ damage remains, and what treatment you need.

How the VA rates this condition

The VA rates this condition based on the type and intensity of treatment you require. Higher ratings correspond to more aggressive treatment regimens, such as daily medication, insulin dependence, or the need for ongoing medical management.

Diagnostic code

DC 7705

Rating range

0% – 100%

Rating levels

Rating criteria are defined in 38 CFR 4.117, DC 7705. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

Your TTP has caused severe, permanent organ damage, such as end-stage kidney disease, major stroke, or ongoing refractory disease. You are unable to work.

What the VA looks for

End-stage renal disease requiring dialysis
Major stroke or permanent neurological deficits
Refractory TTP despite plasma exchange and immunosuppression
Unable to maintain gainful employment
Frequent hospitalizations for acute episodes

Common Pitfalls

⚠Not documenting all relapse episodes with hospitalization records — the frequency of TTP relapses directly impacts your rating and shows the chronic nature of the disease.
⚠Failing to file separate claims for each organ system damaged by TTP — kidney damage, neurological deficits, and cardiac problems can each be rated independently.
⚠Not requesting ADAMTS13 activity level testing as part of your claim evidence — low ADAMTS13 levels confirm the diagnosis and show ongoing disease activity.
⚠Not connecting TTP to military service — physical stress, infections, certain medications, and environmental exposures during service can trigger the first TTP episode.
