VASCULAR DISORDERS OF THE UPPER EXTREMITY
When amputation due to peripheral vascular disease is involved, the impairment due to amputation should be evaluated and combined using the Combined Values Chart.
Impairment of the Upper Extremity Due to Peripheral Vascular Disease
Class 1 Impairment of Upper Extremity, 0—5% The patient experiences neither intermittent claudication nor pain at rest; and The patient experiences only transient edema; and On physical examination, not more than the following findings are present: loss of pulses, minimal loss of subcutaneous tissue of fingertips; calcification of arteries as detected by radiographic examination; asymptomatic dilation of arteries or of veins, not requiring surgery and not resulting in curtailment of activity. or Raynaud’s phenomenon that occurs with exposure to temperatures lower than 0°C (32°F) but is readily controlled by medication.
Class 2 Impairment of Upper Extremity, 6—24% The patient experiences intermittent claudication on severe usage of the upper extremity; or There is persistent edema of a moderate degree, incompletely controlled by elastic supports; or There is vascular damage evidenced by a sign such as a healed, painless stump of an amputated digit showing evidence of persistent vascular disease, or a healed ulcer; or Raynaud’s phenomenon occurs on exposure to temperatures lower than 4°C (39° F). but is controlled by medication.
Class 3 Impairment of Upper Extremity, 25—50% The patient experiences intermittent claudication on moderate upper-extremity.usage; or
There is marked edema that is only partially controlled by elastic supports; or
There is vascular damage evidenced by a healed amputation of two or more digits of one extremity, with evidence of persisting vascular disease or superficial ulceration; or
