Entrants are encouraged to familiarize themselves with the Data File Description and Data Methodology before downloading the Procedure Price Dataset. 

Please note that when dealing with millions of claims, multiple payers, and thousands of providers, there are nuances in billing that cause some anomalies.

Entrants are also encouraged to submit proposals that speak to issues outlined in existing research on the subject of health care pricing (e.g., reports from the  Office of the Attorney General, the Massachusetts Legislature, the Health Policy Commission, the Center for Health Information and Analysis, and the Division of Insurance) and leverage other relevant datasets (e.g., CMS Hospital CompareLeapfrog Hospital SurveyAHRQ Patient Safety IndicatorsMA-RPO).

If you have any comments or questions, please email CHIA at chia.transparency@state.ma.us.
