The most you'll ever pay in a year — your financial ceiling on healthcare costs.
Your out-of-pocket maximum is the most you will ever have to pay for covered healthcare in a single plan year. Once you hit this number, your insurance pays 100% of covered costs for the rest of the year.
Your deductible, copays, and coinsurance all count toward your out-of-pocket max. Think of it as a running total of everything you've personally paid for covered care this year.
Your deductible is $1,500. Your out-of-pocket max is $5,000. You have a bad year — surgery, follow-up care, prescriptions. You pay your deductible, then coinsurance on everything after that. When your total out-of-pocket spending hits $5,000, everything covered for the rest of that year is free.
Like deductibles, family plans have both an individual cap and a family cap. If one person hits their individual max, insurance pays 100% for that person — regardless of what the rest of the family has spent.
The out-of-pocket max is your protection against catastrophic medical bills. When comparing plans, look at this number alongside the premium. A cheaper monthly plan with a $9,000 OOP max is a bigger financial risk than a pricier plan with a $4,000 max — if something serious happens.
