Trends in hospital price transparency after implementation of the CMS Final Rule

Objective

To assess trends in hospital price disclosures after the Centers for Medicare & Medicaid Services (CMS) Final Rule went into effect.

Data Sources and Study Setting

The Turquoise Health Price Transparency Dataset was used to identify all US hospitals that publicly displayed pricing from 2021 to 2023.

Study Design

Price-disclosing versus nondisclosing hospitals were compared using Pearson's Chi-squared and Wilcoxon rank sum tests. Bayesian structural time-series modeling was used to determine if enforcement of increased penalties for nondisclosure was associated with a change in the trend of hospital disclosures.

Data Collection/Extraction Methods

Not applicable.

Principal Findings

As of January 2023, 5162 of 6692 (77.1%) US hospitals disclosed pricing of their services, with the majority (2794 of 5162 [54.1%]) reporting their pricing within the first 6 months of the final rule going into effect in January 2021. An increase in hospital disclosures was observed after penalties for nondisclosure were enforced in January 2022 (relative effect size 20%, p = 0.002). Compared with nondisclosing hospitals, disclosing hospitals had higher annual revenue, bed number, and were more likely to be have nonprofit ownership, academic affiliation, provide emergency services, and be in highly concentrated markets (p < 0.001).

Conclusions

Hospital pricing disclosures are continuously in flux and influenced by regulatory and market factors.
