HR 676 is alot better than Medicare and would cover other things like dental vision etc.
What is "single-payer"?
The term single-payer describes the kind of financing system that H.R. 676 uses. It means that one entity--in this case, established by the government--handles all billing and payment for health care services. Right now, there are thousands upon thousands of "payers"-- HMOs, PPOs, bill collection agencies, etc. The sheer volume of paperwork required by our current system means that administrative waste accounts for roughly 31% of the money spent on health care. The single-payer system would eliminate the wasteful paperwork and administrative costs, redirecting more of our health care dollars to providing care.
Medicare is perhaps the best known single-payer system. Essentially, H.R. 676 would improve Medicare and expand it, so that it covers all Americans, regardless of their income.
Who will be eligible for health care coverage under H.R. 676?
All Americans will be eligible for health care coverage. Every person who enrolls in the program and receive a United States National Health Insurance Card and individual ID number, and that is all anyone will need to receive care.
What health care services are covered?
The program established by H.R. 676 will cover all medically-necessary services without charging co-pays or deductibles. The services covered will include: primary care; inpatient, outpatient and emergency hospital care; prescription drugs; durable medical equipment; hearing, dental and vision care; chiropratic treatment; mental health services; and long-term care.
