How to buy health insurance, step by step
Buying health insurance for the first time can feel overwhelming — too many acronyms, too many numbers, and the sense that one mistake could cost you dearly. The good news is that the process comes down to a few clear steps, and you don't have to do it alone.
The 6 steps to buy your insurance
1. Confirm when you can enroll
The open enrollment period for 2027 runs from November 1 to December 15, 2026. Outside those dates, you may qualify through a life event — moving, marriage, the birth of a child, or loss of other coverage.
2. Gather your household information
You will need: your household size, approximate annual income, and the ages of those seeking coverage. This is used to calculate whether you qualify for a subsidy that lowers your monthly premium.
3. Think about how much medical care you actually use
If you see the doctor often or have a scheduled surgery, a lower deductible is better for you, even if the monthly premium is a bit higher. If you rarely use medical services, a low premium with a higher deductible usually saves you money over the year.
4. Check that your doctor is in the network
Before choosing a plan, confirm that your trusted doctor, your pediatrician, or your regular specialist is within the network — otherwise you could end up paying much more than expected.
5. Review your medication coverage
If you take medications regularly, review the plan's list of covered drugs (formulary) to know how much you will pay for them.
6. Compare, then enroll with the help of a licensed agent
An agent can explain the differences between plans in your own language, check whether you qualify for a subsidy, and complete the enrollment with you — at no additional cost for that service.
The five terms you should understand before deciding
- Deductible — What you pay out of pocket before the plan starts covering most services.
- Premium — What you pay each month to keep your coverage active, whether you use it or not.
- Provider network — The doctors and hospitals the insurer has already negotiated lower prices with.
- Copay — A fixed amount you pay for a specific visit or prescription.
- Out-of-pocket maximum — The annual limit on what you would pay in total; after that, the plan covers 100%.
A common mistake: choosing the plan with the lowest monthly premium without reviewing the deductible or the network. Sometimes that "deal" ends up costing more over the year if you need medical care.
