In-network physicians by specialty within 50 miles. Sample contained 136 plans in the Silver tier on the federal Marketplace in 2015, representing the lowest, second-lowest, median, and highest premium plans in each of the 34 federal Marketplace states. Search radius was defined as 50 miles for most plans; for the 2% of plans that did not offer that radius for their provider network search tool, we used the maximum available search radius (typically 25–35 miles). Percentages are expressed as out of 136 plans for emergency medicine and 135 plans for all other specialties due to defective provider directories.
