The ACA requires insurers selling plans in the marketplace to cover "essential health benefits" — a standardized set of services including hospitalizations, maternity care, mental health and substance abuse treatment, prescription drugs, and preventive care. Standardized plans make it easier for consumers to compare coverage apples-to-apples. Nonstandardized plans are allowed but currently limited — the rule change would expand the number of nonstandardized plans insurers can offer, potentially flooding the marketplace with lower-cost plans that look like insurance but exclude benefits people don't think to check until they need them.
The mechanism of harm is well documented from the first Trump term's promotion of short-term and association health plans: when cheaper, limited plans enter the marketplace, healthy people tend to choose them because they're lower-cost and healthy people rarely use the benefits they're excluding. This concentrates the sicker, higher-cost enrollees in the standardized plans, which drives up premiums for those who need comprehensive coverage most. It's insurance market adverse selection — a known and predictable dynamic that market regulations were designed to prevent.
A trio of senior Senate Democrats — including Senate Health Committee Ranking Member — wrote to condemn the proposed rule this week, noting that it would undermine ACA marketplace stability and harm consumers who rely on comprehensive coverage. The rule is in the proposed stage and has not been finalized. A comment period is open. But the direction is clear: the second-term administration is pursuing the same ACA sabotage strategy as the first, now through regulation rather than legislation.
