Section 388-447-0050 - Progressive evaluation process step III-How does the department determine the severity of physical impairments? "Severity of a physical impairment" means the degree that an impairment restricts you from performing the basic work-related activities in WAC 388-447-0001. Severity ratings range from one to five, with five being the most severe. We assign severity ratings based on the table in WAC 388-447-0020.
(1) We assign to each physical impairment a severity rating that is supported by medical evidence.(2) If your physical impairment is rated two, and there is no mental impairment or a mental impairment that is rated one, we deny incapacity.(3) If your physical impairment is rated five, we approve incapacity.Wash.
