Antiphospholipid Syndrome

DC 7705Hematologic/Lymphatic38 CFR 4.117, DC 7705

An autoimmune disorder where the immune system mistakenly produces antibodies that cause blood clots in arteries and veins. This can lead to deep vein thrombosis, pulmonary embolism, stroke, and recurrent pregnancy loss. The VA rates antiphospholipid syndrome based on the severity and frequency of clotting events and the treatment required.

How the VA rates this condition

The VA rates this condition based on the type, severity, and frequency of your symptoms. The examiner will evaluate your specific symptoms and how they affect your daily life and ability to work.

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

You have catastrophic antiphospholipid syndrome with life-threatening multi-organ failure, or you have severe residuals from recurrent thrombosis that prevent you from working.

What the VA looks for

Multi-organ failure from catastrophic APS
ICU hospitalization for APS crisis
Severe stroke with residual disability
Renal failure requiring dialysis
Unable to maintain gainful employment due to APS complications

Common Pitfalls

⚠Not documenting the laboratory confirmation of antiphospholipid antibodies on two separate occasions at least 12 weeks apart — a single positive test is not sufficient for diagnosis.
⚠Failing to file separate claims for residuals of thrombotic events (DVT residuals, stroke residuals, pulmonary hypertension) in addition to the underlying antiphospholipid syndrome.
⚠Not documenting the burden of lifelong anticoagulation therapy including frequent blood monitoring, bleeding risks, dietary restrictions, and medication interactions.
⚠Not connecting APS to service by documenting that symptoms or clotting events first occurred during military service or within a reasonable time after separation.
