Relative Price and Provider Price Variation

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.

In June 2021, CHIA published relative price for calendar year 2019 for hospitals, final S-RP results for acute hospitals, and CY 2018 relative price for physician groups within the commercial market.

CHIA has also produced an an interactive Tableau dashboard which includes data on provider-specific S-RP results and payer-specific S-RP results.
