NOTES: PDP is prescription drug plan. U.S. total count excludes PDPs in the territories. Totals include sanctioned plans closed to new enrollees as of September of prior year. Average monthly premium is weighted by September 2019 enrollment. Benchmark plan counts include “de minimis” plans, which can retain Low-Income Subsidy beneficiaries despite exceeding the benchmark premium by a minimal amount (up to $2 in 2020). Benchmark plans are not shown for the territories because the LIS is not available to residents of the territories.
