Subject: Re: Boom. The EO I wanted (healthcare pricing)

The order directs the Departments of the Treasury, Labor, and Health and Human Services to rapidly implement and enforce the Trump healthcare price transparency regulations, which were slow walked by the prior administration.
The departments will ensure hospitals and insurers disclose actual prices, not estimates, and take action to make prices comparable across hospitals and insurers, including prescription drug prices.
The departments will update their enforcement policies to ensure hospitals and insurers are in compliance with requirements to make prices transparent.

They can issue regs to require the insurance companies to disclose pricing of care all day long:

(c) issue guidance or proposed regulatory action updating enforcement policies designed to ensure compliance with the transparent reporting of complete, accurate, and meaningful data.
