COUNTY-LEVEL DATA ON TENNESSEE S 2018 OBAMACARE ENROLLMENT

APRIL 19, COUNTY-LEVEL DATA ON TENNESSEE S OBAMACARE ENROLLMENT Last week, we dug into statewide data on open enrollment in private health insurance through the healthcare.gov Marketplace created by the Affordable Care Act (ACA). The maps, charts, and tables below show how key data about Marketplace enrollment vary by county. The following observations were notable in our analysis of the data, but the factors that might be driving them are not yet clear: Counties in Northeast Tennessee experienced the largest declines in enrollment from 2017 to. The average net premium for subsidized enrollees is notably higher in the rating areas that include Davidson County and the Tri-Cities. Meanwhile, these same areas have some of the lowest premiums for the minority of enrollees who are unsubsidized. Note: These county-level data are based on actual enrollment and plan selections during the open enrollment period that ran from November 1 st to December 15 th, 2017. Participating insurers, plan options and premium rates are based on 8 rating areas across the state, which are shown on the maps that follow. ENROLLMENT Tennessee s most populous counties (i.e. Davidson, Shelby, Knox, and Hamilton) have the most enrollees. Just under 229,000 Tennesseans enrolled statewide in Marketplace coverage for. (Figure 1) ranges from 1.8% of population in Montgomery County to 5.1% in Sevier County. Statewide, Marketplace enrollment amounts to about 3.4% of the state s total population. (Figure 2) Change in enrollment from 2017 to varies considerably ranging from a 7.6% increase in Williamson County to a 14.6% decline in Hawkins County. Statewide enrollment was relatively stable with only a 2% drop from 2017. (Figures 3 and 4) FIGURE 1.

Sources: 2017 and Marketplace Open Period State- and County-Level Public Use Files (4) (5) (1) (2) SUBSIDIES The share of enrollees eligible for federal subsidies to offset premiums ranges from 66% in Williamson County to 97% in Decatur County. Statewide, about 84% of enrollees are eligible for federal premium subsidies. (Figures 5 and 6) These subsidies are available to those with incomes under 400% of poverty (about $48,560 for an individual in ). Average monthly premium subsidies range from $569 in Williamson County to $1,082 in Perry County, while growth in subsidies from 2017 to range from 21% in Bledsoe County to 95% in Loudon County. Statewide, average premium subsidies for eligible enrollees were $797 per month, a 51% increase over average subsidies in 2017. (Table 1) Because subsidies are available on a sliding scale, growth in average premium subsidies is driven by both premiums for the benchmark plan on which subsidies are based and the income levels of actual enrollees.

COUNTY-LEVEL DATA ON TENNESSEE S OBAMACARE ENROLLMENT PREMIUMS There is a wide range across counties in average monthly premiums for both subsidized and unsubsidized enrollees. Subsidized enrollees net average monthly premiums range from $12 in Haywood County to $74 in Cheatham and Johnson Counties. Statewide, this average amount is $39 per month, on average. (Figures 7 and 8) Unsubsidized enrollees average monthly premiums range from $514 in Davidson County to $1,007 in Houston County. Statewide, this average amount is $619 per month. (Figures 9 and 10) County-level data on 2017 premiums are not available, which limits our ability to do county-level analysis of premium trends. FIGURE 7.
