How do I choose a health insurance plan?

01Your premium is what you pay every month to keep your coverage

Think of it like a subscription. If you stop paying, your coverage ends. Premiums vary a lot. They depend on the plan, your age, where you live, and whether you get coverage through work or buy it on your own. In general, plans with lower premiums tend to have higher costs when you get care. Plans with higher premiums tend to have lower costs when you get care. That trade-off is at the heart of choosing a plan.

02Coinsurance is a percentage you pay, rather than a flat fee

For example, after you meet your deductible, you might pay 20 percent coinsurance for a hospital stay, and insurance pays 80 percent. If the covered cost is 10,000 dollars, you pay 2,000 dollars and insurance pays 8,000 dollars. Coinsurance can be harder to predict than a copay, because it depends on the total cost of care.

03There are a few common plan types

An HMO, or Health Maintenance Organization, usually requires you to use in-network providers and pick a primary care doctor. You often need a referral to see a specialist. HMOs tend to have lower premiums and lower out-of-pocket costs, but less flexibility. A PPO, or Preferred Provider Organization, lets you see providers in or out of network without a referral, though you pay more out of network. PPOs tend to have higher premiums but more choice. An EPO, or Exclusive Provider Organization, is in between. You do not need referrals, but you usually must stay in network except for emergencies. An HDHP, or High Deductible Health Plan, has a higher deductible and lower premium. It can be paired with an HSA, a Health Savings Account, that lets you save pre-tax money for medical costs.

04Do the math

Do not just look at the premium. Add up the premium for the year, plus what you would likely pay in deductibles, copays, and coinsurance based on your usual care. That total is a better way to compare plans than premium alone. And check the out-of-pocket maximum. That tells you your worst-case cost for covered care.

Check the network before you enroll. Look up your doctors, your preferred hospital, and your pharmacy. If they are out of network, you could pay a lot more, or you could have to switch providers. If you are choosing between two similar plans, the one that includes your current doctors often wins.

05Health insurance will never be simple

But it does not have to be a mystery. Premium is what you pay to keep the plan. Deductible is what you pay first. Copay is a flat fee. Coinsurance is a percentage. Out-of-pocket maximum is your cap. Network is where you get the best price. Start with your health, your doctors, and your budget, then pick the plan that fits those three. That is how you choose well.
