Physician acceptance is an important dimension of access to care, especially for Medicaid patients. We constructed two new measures to quantify primary care physician (PCP) acceptance of Medicaid patients using geocoded Virginia physician addresses and population data and geospatial methods. For each Census block group, we measured the shares of "accessible PCPs" accepting any Medicaid patients or new Medicaid patients. Accessible PCPs were defined as those located within 30-minute travel from patient locations and patient locations were proxied by Census block group geographic centroids. We found that the shares of accessible PCPs accepting Medicaid varied within Virginia, and were significantly lower in urban communities where larger fractions of the population were Hispanic, even controlling for unobserved market-level traits associated with Medicaid acceptance. Policy makers and Medicaid program officials should continue to improve nonfinancial access to primary care, especially by addressing access barriers in communities with high shares of minority residents.
