I'm choosing a plan

Premium, deductible, out-of-pocket maximum — which one matters?

Short answer

All three matter, but the out-of-pocket maximum matters most in a bad year. Add a year of premiums to the out-of-pocket maximum to see the most you could pay for covered in-network care.

What to do

  1. Write down three numbers for each plan: the monthly premium (what you pay to have the plan), the deductible (what you pay before the plan starts paying), and the out-of-pocket maximum (the most you pay for covered care in a year).
  2. Multiply the premium by 12 and add the out-of-pocket maximum to get your worst-case cost for in-network care.
  3. Estimate a typical year too: premiums plus what you usually spend on visits and medications.
  4. Check what does not count toward the maximum, such as the premium itself and, usually, out-of-network care.
  5. Pick the plan whose worst case you could actually afford, then compare the typical years.

What to say

Can you tell me the deductible and the out-of-pocket maximum for in-network care, and whether copays and prescriptions count toward the maximum?

Ask the plan, your employer's benefits office, or a SHIP counselor before you enroll, and ask for the answer in writing.

Choosing the lowest premium without looking at the out-of-pocket maximum. A cheap monthly plan can leave you with a very large bill in the year you actually need care.

The rule behind it

Insurance companies and job-based plans must give you a Summary of Benefits and Coverage (SBC) (45 CFR 147.200). It lists your premium, deductible and out-of-pocket maximum in a standard format. Federal law caps what you pay each year for in-network covered care. For 2026, HealthCare.gov lists the limit for Marketplace plans as $10,600 for one person and $21,200 for a family. Medicare Advantage plans also have a yearly limit, but Original Medicare has none, which is why many people add a Medigap policy.
