All of the enrollment data was based on official reports via the Centers for Medicare & Medicaid Services (CMS) through May 2026 for Medicare, Medicaid & CHIP and through February 2026 for ACA exchange coverage. I included estimated ACA enrollment data for March, April & May 2026 by extrapolating the limited hard data I did have for about a dozen or so states out nationally, including both a lower- and upper-bound range.
My conclusion at the time was that from January 2025 through May 2026...
Yesterday I wrote about the standard monthly Medicaid/CHIP enrollment report published by the Centers for Medicare & Medicaid Services (CMS). I noted that as of April 2026, total combined Medicaid & CHIP enrollment had fallen by another 398,000 people, to around 73.9 million Americans.
I also noted that this figure is nearly 5.1 million lower than it was as of January 2025...the same month that Donald Trump returned to the White House and Republicans took over all three branches of the federal government.
