Washington HealthPlanFinder, the state's ACA exchange, has set the standard for enrollment data reporting, providing a more detailed and complete
account of private plan buyers' demographics and behavior than any other state to date. Washington is a wealthy state, with a median household income (2013) of $60,106, compared to a national median of $51,939. Its buyers of private plans on the exchange (known as Quality Health Plans, or QHPs) are accordingly a much wealthier group than the average among the 37 states that used the federal exchange, healthcare.gov.
Only 12.5% of Washington's QHP buyers have incomes under 150% of the Federal Poverty Level (FPL), compared to 24% in those healthcare.gov states that accepted the Medicaid expansion -- and 50% in healthcare.gov states that refused the expansion. (In non-expansion states, eligibility for QHP subsidies began at 100% FPL, versus 138% FPL in expansion states, and those between 100 and 138% FPL swelled the QHP enrollments, accounting for about a third of all enrollments in non-expansion states.) Low takeup in this low-income band perhaps explains in part why Washington has reached just 32% of its target QHP market as
calculated by the Kaiser Family Foundation, versus 42% for the nation as a whole. Conversely, Washington has been very successful in expanding its Medicaid rolls. The enrollment report tallies 533,628 "Medicaid expansion adults," far exceeding a 2012 Urban Institute forecast of 330,000.
Too many poor buyers of bronze plans
While Washington's relatively small number of enrollees in the 100-150% FPL income band may be in large part a matter of demographics, there is one way in which the state exchange has seemingly failed lower-income buyers. Takeup of Cost Sharing Reduction subsidies, available only with silver plans and only to buyers with incomes below 250% FPL, is lower in Washington than on healthcare.gov, and much lower than in states like New York and Connecticut that take special measures to highlight CSR for those who are eligible for it.
