Combined ratings table

Each new rating combines with the existing combined value using a table in regulations. Online calculators mirror this process for planning.

Why it exists

The model reflects diminishing combined impact of multiple impairments on earning capacity.

Bilateral factor

When both sides of the body qualify under specific rules, an extra adjustment may apply before final combination.
