Relative Price and Provider Price Variation

Relative Price Report

Statewide Hospital Relative Price

Relative Price Methodology
(Updated May 2019)

CHIA reports annually on relative price to examine provider price variation in the Massachusetts commercial market. Relative Price (RP) facilitates comparison of average provider prices, accounting for differences in patient acuity, the types of services providers deliver to patients, and the different insurance product types that payers offer to their members.

CHIA calculates both payer-specific RP, which enables comparison within a payer’s network, and cross-payer statewide relative price (S-RP), which enables comparison across commercial payers.

New for the May 2019 report, CHIA presents relative price information in a series of interactive graphics. If you are unfamiliar with using a Tableau interface, please watch this video.
