Presumptive disability refers to any physical or mental condition which is understood to be so severe that the Social Security Administration automatically grants Supplemental Security Income (SSI) payments to an applicant for up to six months while the Social Security Administration processes their Supplemental Security Income claim. Social Security Disability claimants who are denied SSI benefits after the Social Security Administration review do not have to repay the received Supplemental Security Income benefits. Medical statements must be provided by the claimant's physician verifying they have a presumptive disability. Disabilities must match exactly the categories listed by the Social Security Administration. Presumptive disabilities include: amputations of a leg at the hip, total blindness and deafness, bed confinement due to accident, recent surgery or immobility without a wheelchair, walker or crutches, allegations of a stroke occurring more than 3 months in the past, paraplegia and quadriplegia.
