I have some experience with these datasets and this topic (and anecdotal experience with physicians) and I don't think this will provide anything useful. Essentially, physicians are still incentivized to bill the code that provides them with the largest reimbursement. And, the physicians are incentivized to bill for any possible code they can. What I think the dataset will provide, then, is a good look at negotiations between the physician and the government--not "what will it cost to heal me?"<p>In addition, health centers may very well have a policy to simply charge uninsured more for every procedure. That may be because they "negotiate with insurers for better rates" or "know that the uninsured are more risky and won't pay, so we should charge more."<p>The "best" thing to do, unfortunately, is call around<i>. For a recent cut to my head, I had to call a dozen places to find the best price. I was "insured" but hadn't met my deductible yet so I'd be paying cash. Ranged anywhere from a quoted price of $850 to $120. Pays to call around.<p></i>Calling around, of course, won't be helpful if the agent misquotes you, your insurance company screws up your paperwork, or it's actually out of network.
