It's difficult to see which factors are contributing without a similar breakdown for a similar procedure from somewhere else. Are doctor's costs more expensive in CA due to the increased cost of living? Ditto for administrators, driving up the hospital costs? Is it due to a scarcity of hospital beds / operating tables that the hospital charges 'what the market will bear' in more densely populated regions?
