If objective medical evidence from an AMS already establishes the existence of the
                        MDI, authorize purchase of a CE from a qualified CE source who is not an AMS to document
                        the severity of the impairment and its effect on the claimant’s functioning.
                     
                     Example 1 (physical impairment): Evidence from an AMS establishes the existence of a musculoskeletal MDI. However,
                        you need more information about the current severity of the impairment. A qualified
                        physical therapist may perform the CE required to show the severity of the impairment
                        and its effect on the claimant’s functioning.
                     
                     Example 2 (mental impairment): Evidence from an AMS establishes the existence of a mental MDI. However, you need
                        more information about the severity and functional effects of the mental impairment.
                        You may obtain a CE from a qualified licensed clinical social worker to document the
                        severity and functional effects of the mental impairment.
