Grandfathered plan
Health Insurance
A health plan that an individual was enrolled in prior to March 23, 2010 is considered a grandfathered plan under the ACA. Grandfathered plans are exempted from most changes required by the ACA. New employees may be added to group plans that are grandfathered, and new family members may be added to all grandfathered plans.
