Grandfathered Health Plans (F.S. 627.402)

Group or individual coverage in which someone was enrolled on March 23, 2010 (the ACA's advent) and that has covered someone continuously since — sold through agents and brokers, never the Marketplace. Grandfathered plans skip some ACA rules (no free preventive care or essential-health-benefit mandate) but must still: ban lifetime limits on essential benefits (a grandfathered INDIVIDUAL policy may keep annual limits), cover adult children to age 26 (not the adult child's own child), cap waiting periods at 90 days, and exclude no preexisting conditions. Status is LOST by eliminating substantially all benefits for a condition, raising cost-sharing beyond federal limits, or cutting the plan sponsor's contribution percentage — and plan materials must carry a statement claiming grandfathered status.

A pre-Obamacare policy that gets to play by (some) old rules — as long as nobody changes the deal.
