The groups previously opposed to the legislation switched their focus from opposing the bill to creating new versions of it. As a result, three forms of the bill emerged: John Byrnes', the American Medical Association's, and the administration's bill (known as Medicare). Byrnes was a Republican committee member who proposed that doctors' services and drugs be financed; participation in coverage would be voluntary for the aged. If an elderly patient did need the help, his or her financing would be "scaled to the amounts of the participant's Social Security cash benefits" and the financing would come from the government's revenues. The AMA proposed Eldercare, which provided government financing for physician's services, surgical charges, drugs, nursing home costs, x-ray and lab services. When brought back to the Ways and Means committee, three bills were presented: Byrnes,' Eldercare, and Medicare.
