Let’s see. your question is very broad. Understand that anything I write is a superficial cartoon of a very complex system. Let me give some broad brush strokes and we can refine specific questions later.
First, what is MEDICARE. In a few words, medicare is the health insurance program offered by the federal government to individuals over 65 years old and to a few other categories of folks who are too sick to ever qualify for private insurance, such as renal patients on dialysis. @GracieT mentioned above she qualifies because of a brain injury. Perfect example. Medicare can be roughly divided into 4 parts (A-D). Part A is hospital insurance. It is automatically given to any senior over 65. It covers a certain number of days at a stretch at a hospital, any and all hospital costs. I believe, although I may be wrong, that this period is 180 days. After 180 days, Medicare benefits would have to be extended with help of the hospital OR the patient would have to be discharged or readmitted for another pay period. This is a critically important part because hospital costs are brutally expensive and without this, likely most seniors in the country would be forced into poverty. Part B is roughly outpatient insurance. Seniors have the right to purchase this from the federal government. It covers many, but certainly not all services. For example, a big lacking problem is hearing aids and eye glasses. Part C is an alternative to Part B. It is AKA “medicare advantage” and is managed by the private insurance industry. The idea was that the more efficient private sector would provide a more robust coverage package for less money. The opposite proved to be true because it is a myth the private sector is more efficient than government. Medicare advantage turned out to be more expensive and lead to worse outcomes than medicare B. It is also WAY less administratively efficient. Part D is the Medicare Drug Program that came into being under Bush II. It is entirely managed by the private insurance industry with public funding. It is a mediocre service in terms of outcomes and a bad service in terms of efficiency. It is a windfall for big pharma and the insurance industry. In 2008, the US spent approx 2.3 trillion dollars in healthcare. just over half was spent by the govt and the biggest piece by far of the govt pie is medicare (the other pieces are medicaid, the VA, indian health services, public employee health benefits).
Who benefits? Anyone over 65 and individuals with qualifying conditions who otherwise would be driven into poverty by healthcare costs. Private insurance companies and big pharma benefit over parts C and D.
Problems and solutions. There are many many many many many problems. Some of the biggest ones in my opinion. I will number the list.
1. this sequential approach to health insurance drives up the cost to medicare. since employer-sponsored health insurance knows that it will not have to pick up the tab for old age, there is an active dissincentive not to promote prevention and primary care. The majority of consequences for not investing in primary care and prevention are paid for by someone else – medicare. Makes sense? If we had a single payer system (ie. Medicare for everyone, not just seniors) the incentives would be different.
2. Medicare pays by procedure or intervention. For example, if you come to the hospital with appendicitis, the hospital can bill for each “intervention” it does to you, including placing an iv, each medication, etc. There is an incentive for healthcare providers to “do” as much as possible to make as much money as possible. I’m a doctor and sometimes i take an ER shift. I’ve had supervisors tell me, “oh this person has medicare, why don’t you get an MRI too”. If Medicare gave a global payment or if it paid for results, people would get a lot less unnecessary care. Hospitals would be a lot more in the red though which is a whole other problem.
3. Medicare reimburses less than private insurance. This creates a disincentive for profit-oriented docs or health systems to see medicare patients. A BIG problem is that Medicare is supposed to reduce physicians reimbursement by 20% in order to reduce costs. If this happens, it will be hard for physicians to see medicare patients because the reimbursement will not cover the operating costs of the practice. Congress has to delay this frequently. Extensions to this measure has already happened 3 times this year. A permanent solution is needed, but it is not clear what that solutions is.
4. Healthcare costs are going up and this stretches the ability of medicare to provide comprehensive coverage. The American public is loath to have a conversation of what should and should not be covered. a LOT of money is spent in the last 4 months of life in heroic measures that add little to the health and dignity of the patient. We could save a lot if we simply don’t do as many heroic end-of-life measures that really don’t add that much to the overall outcome. However, just bringing up the topic makes cynical politicians howl about killing grandma. It’s very frustrating we cant even have this critically important national conversation without political fear-mongering. To give these political vipers some leeway, it’s no question that Americans are very afraid of facing our own mortality and not fearing death. Unfortunately, we all die some day.
5. a made-up problem is that medicare will go broke. This is something people who hate govt services love to scream about. Medicare has as much chance of going broke as the military. It’s a public service and we (the people through our duly elected representatives – cough* cough*) determine how much of our taxes go to this service. If we choose to support it because we find it valuable, it will not go broke. If we decide to spend our money on another war or more tax cuts for the ultra-wealthy, then we many not have the money for medicare.
Personal opinion.
What we need is health reform that goes much further than what Obama and the dem Congress pushed through. We really need a single, comprehensive, federal program that insures everyone in America for all their medical, mental, and dental care needs. We need to extend Medicare to cover everyone from birth to death. This would allow us to take all the waste out of the system and focus on evidence-based strategies that would give us the best value for our money. The best way to save medicare is to make it the only insurance in the land.
