Introducing a Free, Centralized Dataset for Hospital Prices

We are excited to introduce our national hospital price transparency dataset, a free resource that consolidates more than 5,000 files published by hospitals and over 5 billion negotiated rates into a single, accessible location. 

While hospitals have been required to publish price transparency data since 2021, the information has been dispersed across thousands of websites in inconsistent formats. By aggregating these files and applying a unified structure, Trilliant Health is transforming technically public but practically inaccessible data into a usable resource for researchers, policymakers, journalists and healthcare organizations. 

This same dataset also powers Oria, our free AI chatbot that enables users to ask natural-language questions about hospital prices. 

What’s New: A Central Source for Hospital Price Transparency Files 

Now, hospital machine-readable files (MRFs) can be accessed in one place, without searching individual hospital websites, parsing inconsistent file formats or performing extensive normalization. 

With this release, users can: 

• Access standardized MRFs from more than 5,000 hospitals 

• Explore 5+ billion negotiated rates in a structured, downloadable format 

• Work with the same dataset that powers Oria’s conversational interface 

• Conduct analysis immediately, without needing specialized technical expertise 

This dataset eliminates the barriers that have historically made transparency data difficult to use at scale. 

Our Approach 

Hospitals are required to publish price transparency files under Executive Order 13877 and the Centers for Medicare and Medicaid Services (CMS) Hospital Price Transparency rule, which requires disclosure of negotiated rates, cash prices and payer-specific charges. 

Although these files are public, accessing them is challenging: 

• Each hospital hosts its own files 

• Naming conventions vary 

• File formats differ 

• Schemas are inconsistently applied 

To make this data usable, we: 

1. Aggregated publicly posted MRFs across more than 5,000 hospitals 
2. Standardized the underlying schemas to create a unified, consistent structure 
3. Normalized key fields to improve comparability across hospitals and payers 
4. Developed a centralized access point for downloading the full dataset 

We then connected this standardized and aggregated dataset to the same infrastructure that powers Oria, enabling conversational queries about the prices for hospital services. 

Limitations 

The dataset reflects the transparency files hospitals publish, which include important limitations: 

• Highly variable formats and data quality. Hospitals interpret CMS schema guidance differently, resulting in inconsistent field naming, payer identifiers and rate structures. 

• Incomplete visibility into care delivery. The files include only hospital-based services, even though most healthcare encounters occur in non-hospital settings. 

• No insight into utilization or market share. The data lists negotiated rates but does not show how often services are used. 

Over time, we will continue refining normalization and expanding the completeness of the dataset.
