The possibility of double assessment for a single loss of function must be guarded against. For example, it would be inappropriate to assess a lower limb amputation by reference to both the amputation table (9.3) and the lower extremity table (9.2).
Where an employee suffers from more than one impairment the values are not added but are combined using the Combined Values Table. The purpose of this table is to give the total effect of all impairments, according to a formula, as a percentage value of the employee's whole bodily system or function (see Table 14).
