More importantly, there are deep-in-the-weeds protections baked into the Affordable Care Act: risk adjustment, reinsurance, and risk corridors.
These programs—collectively called the “three Rs”—aid insurers if they wind up enrolling a population that is sicker and more expensive than projected. They do a crucial bit of policy work: we want plans competing on efficiency and quality, not their ability to attract the healthiest patients.
