The recent Medicare report on variation in hospital “prices” is not exactly news. In fact, I wonder why anyone (including the NY Times and NPR) covered it, let alone make it a lead story.
As you probably know, Medicare reported that hospital charges for specific treatments, such as joint replacement surgery, greatly vary from one hospital to another. (This includes charges for all services during the hospitalization, including room charges, drugs, tests, therapy visits, etc.) Everyone in the healthcare business knows that charges do not equal the actual prices paid to hospitals, no more than automobile sticker prices equal the prices that car buyers actually pay. Except that for the past thirty years, the gap for hospitals greatly exceeds (in percentage terms) the gap for cars. This is not just a nonstory, it is an old nonstory.
So reporters tried to give it a new spin. One angle concerns the uninsured, who may have to pay full charges. I will write about this in a future blog. Another angle is that by publishing these charges, Medicare will encourage patients to shop around. That is the subject of this blog.
I suppose it is okay to tell patients that the amount they might have to pay out of their own pockets may vary from one hospital to the next. But the published charge data is useless for computing out of pocket payments; in fact, it may be worse than useless. As even the NY Times noted, insured patients make copayments based on prices that their insurers negotiate with hospitals. These prices are essentially uncorrelated with charges. So a patient who visits a hospital with low charges may well make higher out-of-pocket payments than a patient who visits a high charge hospital. It is a crap shoot.
