This paper - originally released in October 2020 - was updated in February 2021 to compare 2019 and 2020 WNRAR data through October (previously July). Additionally, a table was added to compare the percentage of members with at least one HCC between metal tiers (Table 6).

In this paper, we provide our observations on the impact of COVID-19 on ACA markets by summarizing data collected through October of each benefit year in the 2019 and 2020 Wakely National Risk Adjustment Reporting (WNRAR) project. The WNRAR project collects summary level risk adjustment data from over 70 health insurance issuers across over 30 states and provides participants with detailed reports several times throughout the calendar year.
