Health care price transparency is that rare policy initiative that elicits support across the partisan divide in the United States. The broad political consensus behind the required disclosure of relevant pricing led administrations of both parties to issue rules through the Centers for Medicare and Medicaid Service (CMS) that force the medical care and insurance sectors to post online an abundance of previously hidden pricing data. It is expected that employers and other payers, with help from technology firms, will use the data to drive competition by extracting lower fees, where possible, and that health care providers will be incentivized to disclose clinical outcomes to justify continued differences in the prices they charge for their services.
