(2) We use the description of how your condition impairs your ability to perform work activities given by the acceptable medical source or your treating provider, and review other evidence you provide, to establish severity ratings when the impairments are supported by, and consistent with, the objective medical evidence.
(3) A contracted doctor reviews your medical evidence and the ratings assigned to your impairment when:
(a) The medical evidence indicates functional limitations consistent with at least a moderate physical or mental health impairment;
(b) Your impairment has lasted or is expected to last, twelve months or more with available medical treatment; and
(c) You are not an active ABD recipient previously determined likely to be disabled as defined in WAC 388-449-0010 through 388-449-0100.
(4) The contracted doctor reviews your medical evidence, severity rating, and functional assessment to determine whether:
(a) The medical evidence is objective and sufficient to support the findings of the provider;
(b) The description of the impairment(s) is supported by the medical evidence; and
(c) The severity rating, duration, and assessment of functional limitations assigned by DSHS are consistent with the medical evidence.
(5) If the medical provider's description of your impairment(s) is not consistent with the objective evidence, we will:
(a) Assign a severity rating, duration, and functional limitations consistent with the objective medical evidence; and
(b) Clearly describe why we rejected the medical evidence provider's opinion; and
(c) Identify the medical evidence used to make the determination.
