I don't see any hope for a "cash only" practice. Obamacare is supposed to make not having insurance "illegal" -- and very few people are going to pay for medical care outside of their insurance plans.
When you have $2500-$10,000 deductibles, you don't really have insurance. It's only catastrophic coverage. If your lucky you have a MSA, and it makes it easier to document the deductible items, and makes them pre-tax.
The concept of high deductible health "insurance" works in favor of the hospitals primarily, but I think it probably won't effect the cash (credit card) practices.
