WAC 388-449-0045. How does the department determine the severity of physical impairments?

We must decide if your physical impairment is serious enough to significantly limit your ability to perform substantial gainful activity. "Severity of a physical impairment" means the degree that an impairment restricts you from performing basic work-related activities (see WAC 388-449-0005 ). Severity ratings range from none to severe. We will assign severity ratings according to the table in WAC 388-449-0035 . We assign to each physical impairment a severity rating that is supported by medical evidence.
