No AA is self insured, they do pay a fee to have companies manage the claims.
AA claims that they pay 80% of the Total cost, its simply not true, they pay 80% of the claim submitted subject to a variety of conditions, such as ;
-whether or not they consider the charge covered, if the Doctor that AA sent you to prescribes treatment that AA considers experimental or simply decides they dont pay for it you pay 100%.
-whether or not they agree with the amount charged, lets say your doctor charged you $100 fpr a proceedure, AA says they should have only charged you $500, AA only pays 80% of the $500 or $400 instead of $800, you have to pay the rest. In other words you would be paying 60% not 80%. Many of their rates are based on charges in the cheapest areas of the country, so if you live in NY or LAX every submission is a battle.
-That you used a doctor in their plan
Once again, AA is self insured, the money you pay goes to American Airlines, not an Insurance company. What you dont use AA uses to pay for what others use. But you are funding it and AA uses your money as part of their claim. AA pays much much less than companies that buy insurance coverage for their employees, thats another part of the big lie. Look at FWAAA numbers. AA brought in around $25billion in 2011 and spent $550 million on Health Benefits. Health benefits consumed less than .002 % of AA's revenue. Most companies spend much more than that, especially smaller companies that are not big enough to be self insured. So when AA says "compared to other companies our size" they are misleading people. Larger companies pay less per person than smaller companies generally.
So you are going to force workers to work night shift then charge them more for insurance because of the negative health effects night shift causes? Please, don't give them any ideas.
