Survey: Medicaid Expansion Changed Mix of Patients

Among all physicians, the average share of Medicaid patients was 16.9% in 2016, up from 15.9% four years earlier. The number of doctors treating Medicaid patients also rose — from 81.9% to 82.6%. That share exceeded 90% for three hospital-based specialties — emergency medicine, anesthesiology and radiology — and was just under 90% for pediatrics, the survey shows.
