The prevalence of narrow provider networks on the ACA Marketplace is trending down. In 2017, 21% of plans had narrow networks, down from 25% in 2016. The largest single factor was that 70% of plans from National carriers exited the market and these plans had narrower networks than returning plans. Exits account for more than half of the decline in the prevalence of narrow networks, with the rest attributed to broadening networks among stable plans, particularly among Blues carriers. The narrow network strategy is expanding among traditional Medicaid carriers and remains steady among provider-based carriers and regional/local carriers.
《平价医疗法案》市场上窄供应商网络的普及率呈下降趋势。2017年，21%的保险计划拥有窄网络，低于2016年的25%。最大的单一因素是，全国性保险公司70%的保险计划退出了市场，这些计划的网络比重新进入市场的计划更窄。退出市场的计划占窄网络普及率下降的一半以上，其余下降归因于稳定计划中网络的拓宽，尤其是蓝十字蓝盾保险公司的计划。窄网络策略在传统医疗补助保险公司中不断扩大，在基于供应商的保险公司以及地区/本地保险公司中保持稳定。
