The source adds the following:
*"The federal Hospital Price Transparency Rule, which took effect on January 1, 2021, requires hospitals to post all prices online in the form of (i) a single machine-readable file of standard charges for all items, services, and drugs by all payers and all plans, the de-identified minimum and maximum negotiated rates, and all discounted cash prices, as well as (ii) prices for the 300 most common shoppable services either as a consumer-friendly standard charges display or as a price estimator tool. 
Combined with requirements for disclosure of systemwide prices and historical claims in the Transparency in Coverage Rule (TiC) and the Consolidated Appropriations Act of 2021 (CAA), respectively, the Hospital Price Transparency Rule is intended to empower healthcare consumers – patients, employers, and unions as purchasers – with ease of access to compare prices."

**Beginning July 1,2024, key price transparency requirements were rolled back. "The updated rule allows hospitals to post percentages and algorithms instead of actual prices effective July 1, 2024, and will permit estimates and averages instead of dollars-and-cents prices beginning on January 1, 2025." Therefore, Patent Rights Advocate "assessed each hospital for its “Pricing Data Sufficiency” based on the availability of actual, dollars-and-cents prices found in the files."
