Hospital Price Transparency Data Still Hampers Rate Comparisons
In a Peterson-KFF Health System Tracker analysis, researchers examine how CMS's revised hospital price transparency rule, effective January 2026 with enforcement beginning April 2026, affects the usability of hospital pricing data. The revisions require hospitals to encode negotiated rates as dollar values whenever determinable in advance, and to report new "allowed amounts" (median, percentile, and payment counts) when rates are expressed as percentages or algorithms instead. Reviewing sample admission codes using Turquoise Health's aggregated data, the authors find clearer CMS guidance has improved reporting precision, but several issues still complicate comparability: dollar-amount fields are used inconsistently for both base and final rates, some arrangements generate duplicate-looking rate entries, and hospitals inconsistently use algorithm versus free-text note fields, affecting whether additional payment detail is captured.
