During the pandemic, from February 2020 to May 2022, Medicaid enrollment increased by 18 million, or 29%, according to administrative data that CMS collects from states. That's mainly because of a moratorium on disenrollments that began in March 2020 and has yet to end. The moratorium will end when the federal government declares an end to the Public Health Emergency, which will happen in mid-January 2023 at the earliest (the PHE has been extended repeatedly in 3-month increments).
As noted in my last post, the disruption that may be triggered by the resumption of state "redeterminations" of Medicaid enrollees' eligibility, and subsequent disenrollment of some, is a focus of considerable angst -- and preparations, in states where Medicaid personnel are committed to keeping as many people insured as possible, to proceed with due deliberation and compassion. The Urban Institute has estimated that 15 million people may be disenrolled over the course of a year, the time period that CMS has asked states to devote to clearing the "redetermination" backlog. The Kaiser Family Foundation (KFF) estimates somewhat more modest losses, in a range from 5.3 million to 14.2 million.
This week the Census Bureau released its annual report on health insurance coverage in the United States. Based on the annual supplement to the Current Population Survey, the report shows a more modest increase in Medicaid enrollment from 2020 to 2021 -- 0.9% -- than CMS's administrative data would indicate. According to CMS, Medicaid and CHIP enrollment increased by 6.6 million from December 2020 to December 2021. That's about 2% of the population.
The Census Bureau also released a second report, spotlighting health insurance changes over two years, and based on the American Community Survey. which interviews people throughout the year about their current insurance status (the CPS, conducted early in the year, asks respondents if they were insured at any point in the past year). The ACS also shows a gap between Medicaid enrollment gains as reflected in administrative data compared to the survey data. According to the report, the percentage of the population insured by Medicaid increased by 1.3% over two years, from 2019 to 2021 (based, again, on surveys conducted throughout each year). The administrative data records an increase of 11.7 million enrollees from June 2019 to June 2021. That's about 3.5% of the population.
An analysis of the ACS data by KFF attempts to explain this gap. The explanation suggests to me that the disenrollments that will begin at the end of the PHE may not be as disruptive as "15 million disenrolled" might indicate -- at least in states that work in good faith and with due diligence to establish contact with all enrollees, accurately determine their status, and help them consider their options.
