Short term rehabilitation care for elderly parent. Mother hurt her knee and cannot walk. Went to ER and they discharged her. She cannot walk and must use a wheel chair while she recuperates. She lives alone (we live over 4 hours away) and has stairs in the house. Currently cannot drive. She has medicare part A and B plus a supplemental policy (65+). Will insurance pay for a few weeks in a rehab facility while her knee recovers? Who do we talk to.
