President Trump has made price transparency a centerpiece of his health care agenda. Friday he announced two regulatory changes in a bid to provide more easy-to-read price information to patients. The first effort targets hospitals, finalizing a rule that requires them to display their secret, negotiated rates to patients starting in January 2021. The second is a proposal to make insurance companies show patients their expected out-of-pocket costs through an online tool. That proposed rule is subject to 60 days of public comment, and it’s unclear when it would go into effect.
