In further review, it would seem something else was at work here.
Hospital care price growth had been dropping since 2006. I'd like to see the graph for the past 20 years actually....does such a graph exist ? Service prices appear to have been leveled off.
Altarum has a longer time series, but not broken down by component. This is year-over-year change in all health prices (hospitals, physician and clinical services, perscription drugs, nursing home care, dental services, home health, other professional, other personal, other nondurable medical products, DME) going back 25 years:
The current period of decline in growth began in 2010. The only other similar period was the invention of the Medicare physician fee schedule in the early '90s followed by the price clamp-down by commercial payers during the managed care era of the mid-90s.
Now you have payers again getting aggressive in price negotiations (this is what all the hooplah over narrow and tiered networks is about), and increasingly engaging providers in risk-based contracts in which payment to the providers is impacted by the quality of the care they deliver and its total cost (i.e., their prices times their service volume). Those effectively dull the impact of larger pricer increases, making them less attractive (better performance instead becomes the route to better financial results).
At the same time, as deductibles rise you've got more people becoming price sensitive to anything priced below the deductible.
These trends started prior to 2010 and certainly before 2013.
Some of it sure, but it's all been accelerated and institutionalized in large part due to the ACA. The old fee-for-service world has started to melt away because of the ACA. We're now firmly moving into a world of value-based purchasing, risk-based contracting, and accountable care. That's a big deal and it's a big shift.
