Certification & Evaluation procedure for Multiple Disabilities

Evaluation of Multiple Disabilities

Whenever there are more than two values to be combined, first two values are calculated using the formula

                                a + b(90-a)

                                          90

Where a = higher value

             b = lower value

 

To clarify the calculation of percentage of disability in a case of multiple disabilities where there are more than two disabilities, hypothetical example of calculation of percentage of disabilities is give below :-

 Suppose in a patient, there are three disabilities, i.e., Locomotor impairment, Hearing Impairment, Visual Impairment and the individual calculation of percentage of disability of

 

Locomotor                 =                30%

Hearing                      =                20%

Visual                         =                15%

 

The formula     a + b(90-a)

                                      90

 

Will be applied to the two disabilities having higher percentages, i.e., Locomotor impairment (30%) and Hearing impairment (20%). The figure arrived by applying this formula will be

 

                                30 + 20(90-30)   = 30 + 13.3   = 43.3 %

              90          

 

Again the formula   a + b(90-a)

                                             90

 

shall be applied to calculate the total percentage of three disabilities, i.e. Locomotor impairment and Visual Impairment ( 15%)

 

Where   a =  43.3% ( Combination of Locomotor impairment and Hearing Impairment)

               b =  15% ( Visual Impairment)

 

                = 43.3 + 15 (90-43.3) = 43.3 + 15(46.7) = 43.3 + 7.78 = 50.81%

90                                            90

 

Thus the total percentage of multiple disabilities in this case will be 50.81%
