A condition where the immune system or other factors destroy red blood cells faster than the body can replace them.
Because ratings at every level turn on the type and frequency of treatment, your medical records are the most direct evidence. Treatment records showing continuous intravenous infusions or an uninterrupted course of immunosuppressive drugs support the 100% level. Records of a bone marrow transplant, including the hospital admission date and discharge date, are needed to establish the period covered by that rating.
For the 60%, 30%, and 10% levels, records that show exactly how many courses of immunosuppressive therapy were prescribed or administered within a 12-month period are critical. Pharmacy records, infusion logs, and physician notes that document each course and its dates help establish frequency. Lab results showing hemoglobin levels, reticulocyte counts, or other markers of hemolysis can support the clinical picture your provider describes.
For the 0% level, provider notes stating that the condition is currently asymptomatic and requires no active treatment reflect that criterion. If you have also had a splenectomy, operative reports and discharge summaries for that procedure would support a separate evaluation under diagnostic code 7706.
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.
