CHIA reports annually on relative price to examine provider price variation in Massachusetts. Relative Price (RP) facilitates comparison of average provider prices while accounting for differences in patient acuity, the types of services providers deliver to patients, and the different insurance product types (e.g., HMO, PPO) that payers offer to their members.
For acute hospitals, CHIA calculates both payer-specific RP, which enables comparison ofprovider prices within a payer’s network, and cross-payer statewide relative price (S-RP), which enables comparison of acute hospital prices across all commercial payers.
For other hospital types (chronic, rehabilitation, and psychiatric hospitals/acute hospitals with dedicated behavioral health units), CHIA calculates payer-specific RP results, enabling comparison within a payer’s network of hospitals that provide similar services. Payer-specific RP is also calculated for physician organizations.
In August 2023, CHIA published relative price results with data through CY 2021 for Massachusetts hospitals and physician groups. CHIA also produced an interactive Tableau dashboard which enables users to explore this data in more detail.
