To compare access at community health centers (s) vs private offices (non‐CHCs) under the Affordable Care Act.
Ten state primary care audit conducted in 2012/2013 and 2016.
s and non‐s were called. We calculated difference in differences comparing s vs non‐s by caller insurance type.
In both rounds, Medicaid and uninsured callers had higher appointment rates at than non‐s. appointment rates significantly increased between 2012/2013 and 2016 for both employer‐sponsored and Medicaid callers, with no significant wait time changes. Appointment rates increased (13.5% points, < 0.001) and wait times decreased (−5.7 days, = 0.017) at s relative to non‐s for employer‐sponsored insurance.
Appointment availability at s improved after implementation, without increased wait times.
