Patricia Clark, now 86, went into the hospital about four years ago for a hip replacement. Patricia had had health problems over the years, but was doing well at the time, except that her declining mobility was making it increasingly difficult to live independently. Her doctors expected her to fare better with a new hip. Unfortunately, Patricia suffered a debilitating stroke in surgery and was left unable to get around on her own or live at home by herself. She was admitted to a rehabilitation center but did not improve, and now she lives there as a nursing home resident. Medicare pays for most medical care that Patricia needs, but Medicaid pays for her nursing home care
