Hmm ok well when I'm talking about abuse of the system I'm not talking about the paperwork you fill out, I'm talking about the abuse of doctor's time and the abuse of services by the doctor's themselves, not just the patients.
I'd have to investigate the medical system here, but in the USA, UK, and Canada there are 2 ways that doctors are paid:
1) Salary -- this is usually at community hospitals in the USA, and then depends on province in Canada
2) By procedure -- ie Fee For Service
This is more common in Canada and as far as I know the more popular system in the USA.
In Canada for instance, when you go and have a baby your doctor will get paid based on which procedure they do. ie Straight forward vaginal delivery is one price, Caesarian is another, a delivery with X complication another, they get paid for their follow up, they get paid for being on call, the Anaesthetist gets paid for being there (my sister has told me that while the rest of the team will let immigrants that aren't yet covered by Canada medicare go, the Anaesthestists have literally chased patients down the hallway to make sure they get paid their few thousand dollars!).
Then the hospitals have to pay for the running of all the lab work and the machines. An MRI costs between 3500 and 10000 USD to run, each time.
When you look at private medical insurance all of these costs are not covered by the government and by taxes, they are passed onto YOU, the subscriber.
The doctors in a private system are making money from the insurance company -- the more labs, tests, procedures they run, the more money they make. This is the abuse of the system that leads to YOU paying more in health insurance fees.
I have not fully investigated the system here in Argentina, but those doctors working with private plans make more money than the guys at the private hospitals, and I can only imagine it's because the system is similar to that of the USA -- run an MRI? Make 50 bucks, see 50 patients in a day? Make X number of dollars for each one.
Every time you go to a doctor here you sign your receipt at the doctor's office after they swipe your insurance card. Those receipts go off to the company, they pay the doctors based on visits and procedures. OSDE etc start losing ground on the margin between what patients are paying in insurance and how much they are paying out to the MDs, and then your prices get jacked.
It's all a business, it's not about keeping patients healthy. It's about making money.
