Cost-Sharing as a Barrier to Accessing Care at FQHCs and RHCs for Rural Medicare Beneficiaries. Cost is often a significant barrier to accessing care for the rural Medicare population, so having a better understanding of the variations in cost-sharing per claim (deductibles and coinsurance amounts) at various types of safety-net facilities is important. The purpose of this study from the North Carolina Rural Health Research and Policy Analysis Center is to investigate cost as a barrier to accessing care at Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) for the rural Medicare population.
