or at least the US Private Insurance system. It is an old rule of thumb that 20% of your population accounts for 80% of your claims. Hospitals account for 50% of all spending and most of the excessive cost and profit.
PCIP found this out when they blew through their allotted 5 billion to quickly. Being from the Government and always looking to help they had a very effective solution;
"The federal PCIP program run by the U.S. Department of Health and Human
Services (HHS) will set most reimbursement levels at just 100 percent of
the Medicare reimbursement rates, officials said"
For doctors this might be a slight haircut but for large hospitals, the ones racking up large bills, used to getting 300-400% of Medicare, or more, this will be noticeable.
If the Government was truly interested in being useful they would provide catastrophic insurance to reign in hospital spending and leave all the day to day care and the other 80% of the population alone. This would immediately make insurance affordable for the majority of the country which would likewise drop the percentage uninsured. It would also do so without all the other intrusive programs and requirements of the ACA.
