The more insurance is used for standard procedures that should be paid for separately, the higher insurance rates go. If insurance refused to cover petty and routine thing like vaccinations, blood tests, and check-ups, going to see a doctor might be more affordable.
Insurance is nothing more than a guarantee of payment. If you don't have insurance, there's no guarantee the doctor will receive payment for his (or her) services. If you have insurance, the doctor has already agreed with the the insurer what he (or she) will be reimbursed for their work. If you walk in with empty pockets and say "FIX ME!" like every other irresponsible, illegal, uninsured, broke-ass mother****er, the doctor is going to charge you commensurably to recoup his (or her) services regardless of if your broke ass intends to pay him (or her) at all.
An example... I called my ophthalmologist to schedule a checkup. I asked what the "cash" price was to have him take a look at my eyes. The quote? $500. $500 just to walk in the damn door. I told them I was a return patient... they lowered their price to $150. Now, I have insurance and my copay is about $25, but someone still has to pay that $500. You have to ask where does all this start? It starts from people not paying for routine medical care and checkups and leaving doctors to haggle with insurance companies to earn a living. Who the hell wants that?
By the way, Ted Kennedy authored the first HMO legislation in Congress in 1968. Take it up with him.
