CMS

Last month I posted a massive 3-part series of articles which looked at nearly 3 dozen changes being proposed by the Trump Regime's Centers for Medicare & Medicaid Services (CMS) to how the Affordable Care Act will be administered starting this fall (for the 2027 plan year).

The changes ranged from the mundane (for instance, one provision simply says that the per enrollee user fees paid by insurance carriers to HHS to pay for HealthCare.Gov's operations will remain the same as they are this year) to the devastating (up to 1.5 million legally-present immigrants who were previously eligible for ACA tax credits, including victims of domestic abuse and human trafficking, either already are or will soon become ineligible for financial assistance).

Most are somewhere in between.

Medicare Advantage (technically "Medicare Part C" & originally called "Medicare+Choice") is a type of health plan in the United States offered by private companies as part of the original Social Security Act of 1965 that created Medicare. It permits a private insurance option that wraps around traditional Medicare. Medicare Advantage plans attempt to fill some coverage gaps and offer alternative coverage options.

Under Part C, Medicare pays a plan operator a fixed payment for each enrollee. The operator then pays for their medical expenses. Traditional Medicare directly compensates providers on a fee-for-service basis. Plans are offered by integrated health delivery systems, labor unions, non profit charities, and health insurance companies, which may limit enrollment to specific groups of people (such as union members).

The Trump Regime has published an update to the official Medicaid/CHIP enrollment data:

November 2025 Key Findings

Medicaid and CHIP Enrollment

• In November 2025, 76.0 million individuals were enrolled in Medicaid and CHIP.
• 68.8 million individuals were enrolled in Medicaid, and 7.2 million individuals were enrolled in CHIP.
• 39.8 million adults were enrolled in Medicaid, and there were 36.2 million Medicaid child and CHIP enrollees.

Total Medicaid/CHIP enrollment in November 2025 dropped about 1.5% from October 2025, or by around 1.17 million people.

IMPORTANT: You have until March 13th to SUBMIT A PUBLIC COMMENT to CMS about any of the proposed changes listed below!

It may not make any difference but believe it or not sometimes it does, even under the Trump regime...and in fact in some cases they're actively stating that they're seeking comment as opposed to just ramming the proposed changes through.

The Patient Protection & Affordable Care Act includes a long list of codified instructions about what's required under the law. However, like any major piece of legislation, many of the specific details are left up to the agency responsible for implementing the law.

UPDATE: Someone correctly pointed out that it’s a bit unfair to tell people to “be afraid” without giving them any action items to try and stave off the uglier changes being proposed. You have until March 13th to submit a comment to CMS.

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 dropped by 517,000 people, or roughly 2.5%, standing at 20.4 million nationally as of last June, so it doesn't look like the Trump Admin has started cooking these particular books, at least not yet.

This will likely change radically with the draconian provisions of the GOP's Big Ugly Bill starting to kick in soon, however.
