CMS posts claimed November 2025 Medicare enrollment; over 51% now enrolled in Med Advantage

 The Centers for Medicare & Medicaid Services just published updated enrollment data for Medicare, adding November 2025 to the data archive.

Whether the data posted since January 20, 2025 is accurate or not, I can't say for certain, but at least they're updating it...and so far, at least, I don't see anything in their monthly reports which is setting off any obvious red flags.

In any event, according to the latest report, as of November 2025:

• Total Medicare beneficiaries are up to 69.73 million (up ~57K month over month)
• Traditional/FFM Medicare beneficiaries are at 34.10 million (up ~28K m/m)
• Medicare Advantage beneficiaries reached 35.63 million (up ~18K m/m)
• 12.08 million Medicare enrollees (17.3% of the total) were "Dual Eligibles"...that is, enrolled in both Medicare and Medicaid.

After crossing the 50% threshold two years ago, Medicare Advantage has now been, for good or for bad, the default option for Medicare enrollment ever since, with over 51% of all enrollees now utilizing Advantage plans.

It's also worth noting that, given the Musk/Trump Admin's obsession with erasing any reference or data regarding gender, race or ethnicity, the Medicare enrollment reports still include breakouts of those demographic factors.
