You might have heard terms like out-of-pocket max or limit. They mean the same thing. They each refer to the most you could pay during a 12-month coverage period for your share of the costs of covered services. Typically, deductibles, copays and coinsurance all count toward your out-of-pocket maximum. Things like your monthly premium or anything your plan doesn't cover (like out-of-network services) do not.
If you meet your out-of-pocket maximum, your plan will pay for 100% of your covered health care costs (up to the allowed amount). Let’s say you have an annual out-of-pocket maximum of $6,000. That means once you’ve paid $6,000 out-of-pocket for your covered health care, usually including deductibles, copays and coinsurance, your plan will cover any future (covered, in-network) health care services during your coverage period.
