In a report issued last September, Covered California, the golden state's ACA exchange, announced that effectuated enrollment in private health plans through the exchange had reached an all-time high of 1.53 million (1,527,730) as of June 2020. That was in the midst of an emergency Special Enrollment Period (SEP), effectively a second open enrollment season, implemented by California in response to the Covid-19 pandemic. (In normal years, SEPs are open only to individuals who can demonstrate a qualifying "life change," such as loss of job-based insurance.)
The emergency SEP ran from March 20 through August 31, 2020. According to the September report, SEP enrollment increased by more than 100% over the same period in 2019, to 289,460. As the CoveredCA report stresses, that's in contrast to a mere 27% increase in SEP enrollment in the 38 states then using the federal exchange, HealthCare.gov, for which the Trump administration refused to open an emergency SEP. In September, active membership enrolled through CoveredCA reached a new all-time high, 1,551,470.
Driven largely by the boost in SEP enrollment, plan selections as of the end of OE 2021 in California finally surpassed their 2016 high point of 1,575,340, reaching 1,625,546. (The term "plan selections" acknowledges that not all those who "enroll" in plans during OE make a first payment and thus "effectuate" enrollment and become, in CoveredCA parlance, "active members").
While plan selections as of the end of OE have always served as the headline number for ACA marketplace enrollment, they provide a somewhat misleading picture. Every year, an average of about 10% of those who "enroll" in plans during OE never pay their first premiums, and attrition continues throughout the year, as disenrollments exceed SEP enrollments -- at least through 2019, the last year for which monthly enrollment has been published. But attrition has been shrinking beginning in 2018, perhaps because the silver loading that began that year sharply reduced net-of-subsidy premiums for many enrollees, including a substantial number who paid zero premium. In 2016, national enrollment as of December was 28% below the end-of-OE total for plan selections. In 2019, December enrollment was just 20% below the end-of-OE tally.
