Combining Multiple Impairments

If 2 conditions are present, with one having an impairment A and the second an impairment B:

combined value for A and B =

= A + (B * (1 - A))

where:

• A is the decimal representing the impairment due to the first condition

• B is the decimal representing the impairment due to the second condition

• A is the larger of the 2 decimals

• The combined value is a decimal corresponding to the total percent impairment.

• Both A and B must be of the same impairment level (hand or foot, extremity, total person, etc.).

If more than 2 conditions are present, the above steps are repeated, starting with the largest decimal and progressing to smallest:

• The combined value for the first 2 decimals is used with the third decimal to generate a second combined value.

• The second combined value is used with the fourth decimal to generate a third combined value.

• and so on, until all the values are combined.
