CMS posts Medicaid expansion enrollment as of June 2025: 20.4 million nationally

The Centers for Medicare & Medicaid Services (CMS) has posted an official update to the enrollment data for ACA Medicaid expansion through June 2025.

According to the new report, total enrollment from December 2024 through June 2025 only dropped slightly (just over 330,000 people, or just 1.6%), and remained at almost exactly 20.4 million nationally, so it doesn't look like the Trump Admin has started cooking these particular books, at least not yet.

Enrollment through June remained remarkably stable, although this is going to change radically with the draconian provisions of the GOP's Big Ugly Bill starting to kick in soon.
