Class 1: 0% when there are no complaints or evidence of disease and the usual activities of daily living can be performed; no blood transfusion is required; and the hemoglobin level is 10-12gm/100ml.(b)
Class 2: 30% when there are complaints or evidence of disease and the usual activities of daily living can be performed with some difficulty; no blood transfusion is required; and the hemoglobin level is 8-10gm/100ml.(c)
Class 3: 70% when there are signs and symptoms of disease and the usual activities of daily living can be performed with difficulty and with varying amounts of assistance from others; blood transfusion of 2 to 3 units is required every 4 to 6 weeks; and the hemoglobin level is 5-8gm/100ml before transfusion.(d)
Class 4: 85% when there are signs and symptoms of disease and the usual activities of daily living cannot be performed without assistance from others; blood transfusion of 2 to 3 units is required every 2 weeks, implying hemolysis of transfused blood; and the hemoglobin level is 5-8gm/100ml before transfusion.(2)
White blood cell system impairments are rated under the following classes:(a)
Class 1: 5% when there are symptoms or signs of leukocyte abnormality and no or infrequent treatment is needed and all or most of the activities of daily living can be performed.(b)
Class 2: 20% when there are symptoms and signs of leukocyte abnormality and continuous treatment is needed but most of the activities of daily living can be performed.(c)
Class 3: 40% when there are symptoms and signs of leukocyte abnormality and continuous treatment is needed and the activities of daily living can be performed with occasional assistance from others.(d)
Class 4: 73% when there are symptoms and signs of leukocyte abnormality and continuous treatment is needed and continuous care is required for activities of daily living.(3)
Splenectomy is given an impairment value of 5%.(4)
Hemorrhagic disorders receive 5% impairment if many activities must be avoided and constant endocrine therapy is needed, or anticoagulant treatment with a vitamin K antagonist is required. Hemorrhagic disorders that stem from damage to other organs or body systems are not rated under this section but are rated based on the impairment of the other organ or body system.
