Not a lawyer but the thing I don't get is in general contracts needs certain elements to be enforceable. Meeting of the minds... having a layman sign sheet after sheet of documents that are in legalese most of which they do not understand hardly satisfies a meeting of the minds to me. Which brings me to another thing, the patient/guardian, is getting these forms while under duress of a real/perceived medical emergency and in general, contracts entered into under duress may not be enforceable especially when with huge differential in the power and sophistication of the parties. I just find it unseemly at best and near criminal at worst.
I do my DD when I can but in an emergency that can be near impossible. So far, I've been pretty happy with my insurance and providers but have only dealt with "emergency" situations with my ex-wife and probably got a little lucky.
Not a king either, but if I was king for a day, I'd have menu pricing with standardized definitions/terminology, all parties pay the same, no negotiated prices (for gov't, insurance co, anyone, no exceptions with big penalties). Patients are to told up front the total to be billed and can better choose facilities that are cost effective. Insurance would clearly state how much they'll pay (either in $ or percent) for each service/drug regardless of provider using the same terminology. This would generate some cost competitiveness and eliminate some of the leaches/middlemen.
