When amputation due peripheral vascular disease isinvolved, the impairment due to amputation should be evaluated accordingto Section 3.2a, 3.2b, 3.2c, or 3.2d, and combined with the appropriatevalue in Table 48, using the Combined Values Chart. Note that the valuesin Table 48 related to impairment of the lower extremity.
