Auto-enrollment in Medicare Advantage isn’t a nudge. It’s a trap

The Trump administration is reportedly weighing a policy that would make private Medicare Advantage (MA) the default enrollment option for every new Medicare beneficiary. Officials are billing it as a technocratic nudge toward better, more coordinated care. If that were truly the goal, payment models already lowering costs through the coordination of care could be more aggressively expanded in traditional Medicare. Instead, MA auto-enrollment is a stealth effort to privatize Medicare by making for-profit insurance the path of least resistance for millions of seniors who never asked for it. Edit note: Worth noting that CMS director Chris Klomp stated the agency is also considering ACO/Medicare Shared Savings Program models — not only private MA plans — as potential auto-enrollment defaults? The author’s framing focuses exclusively on the MA track, which is the more consequential and controversial option, but you may wish to add a brief parenthetical acknowledging the ACO alternative to pre-empt criticism of selective framing. Today, new beneficiaries who do not make an active plan selection are enrolled in traditional, government-run Medicare — the default that has anchored the program since its inception. Under this proposed change, those seniors would be automatically funneled into private MA plans chosen by algorithms. CMS has not released details of its plan, but legislation introduced in the House would automatically assign new beneficiaries to the lowest-premium MA plan in their ZIP code and lock them in for three years. Assigning new enrollees to the plans with the narrowest networks and highest prior authorization rates prioritizes insurer profits over patient access, leaving vulnerable seniors saddled with inferior coverage. The proposal’s architects are counting on a behavior pattern well documented for decades: Most people accept whatever default they’re assigned, whether it’s retirement savings, organ donation, or insurance selecti
