Navigating New Waters: How Did MACRA 2015 Transform Practices Among Medicare Part B Physicians?

ABSTRACT:

Objectives

To assess whether physicians participating in the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) exhibit different billing behaviors and practice patterns compared to non-participating physicians after MACRA implementation.

Study setting and design

A quasi-experimental staggered difference-in-difference design was used to compare pre-and post-MACRA changes among participants and non-participants from 2013 to 2021. Primary outcomes included annual submitted charges, annual Medicare payments, and charge-to-payment ratios. Secondary outcomes were average charges and payments per beneficiary, total services, and the number of beneficiaries served.

Data sources and analytic sample

The study analyzed secondary data from Centers for Medicare & Medica
