               EXCEPTION: For claimants with a documented diagnosis of Amyotrophic Lateral Sclerosis (ALS),
                  commonly known as Lou Gehrig’s disease, we must establish the EOD before age 64 years
                  and seven months, for the claimant to be eligible for DWB-Medicare benefits. Claimants
                  diagnosed with ALS are not required to serve the 24-month qualifying period for Medicare.
                  (For more information about ALS and Medicare entitlement, see DI 23580.001.)
