The short answer
Every ACA Marketplace plan has an out-of-pocket maximum — a yearly cap on what you pay for covered, in-network care. Once your deductible, copays, and coinsurance add up to that limit, the plan pays 100% of covered costs for the rest of the year. This cap is one of the ACA's most important protections, because it puts a ceiling on your costs in a serious health year.
So no matter how bad a year gets medically, your in-network costs for covered care can't exceed that maximum.
What counts toward it
Your deductible, copays, and coinsurance for covered, in-network services count toward the out-of-pocket maximum. Premiums do not count, and out-of-network care generally doesn't count (and may not be capped at all on some plans). There's an individual maximum and, for families, a family maximum. If your income qualifies you for cost-sharing reductions on a Silver plan, your out-of-pocket maximum is lowered.
So staying in-network matters, both for cost and for the cap to apply. Our guide to checking your doctor's network status covers that.
Why it matters
The out-of-pocket maximum is what makes a Marketplace plan real insurance against catastrophe — it's the number that limits your downside. When comparing plans, look at the out-of-pocket maximum alongside the premium and deductible, since a plan with a lower maximum protects you better in a bad year. Our cost estimator helps you weigh these together.
The bottom line: know your plan's out-of-pocket maximum — it's the ceiling on your yearly risk.
