Choosing health insurance can be confusing because a plan with a low monthly premium is not necessarily the least expensive option overall. Deductibles, copayments, coinsurance, provider networks, prescription coverage, and out-of-pocket limits can all affect what you actually spend.
The right plan depends on your health needs, expected medical expenses, household budget, and the doctors and hospitals you want to use.
Start With the Monthly Premium
The premium is the amount you pay for health insurance each month, whether or not you use medical services.
A lower premium can make a plan attractive if your priority is reducing monthly expenses. However, lower-premium plans may have higher deductibles or other out-of-pocket costs.
For that reason, do not compare plans using premiums alone.
HealthCare.gov recommends considering estimated total yearly costs, including premiums, deductibles, copayments, and coinsurance.
Understand the Deductible
A deductible is the amount you generally pay for covered services before the insurance plan begins paying according to the plan’s rules.
For example, if a plan has a $2,000 deductible, you may have to pay the first $2,000 of certain covered healthcare expenses before the plan begins sharing costs.
Some services may be covered before the deductible, depending on the plan. HealthCare.gov also notes that Marketplace plans cover certain preventive services without cost-sharing under applicable rules.
Learn About Copayments and Coinsurance
A copayment is usually a fixed amount you pay for a covered service. For example, a plan might require a fixed payment for a doctor’s visit.
Coinsurance is different because it is generally a percentage of the cost of a covered service.
A plan could therefore have a $30 copayment for certain office visits while requiring coinsurance for hospital services.
Understanding these costs can help you estimate what you might pay when you actually use healthcare.
Check the Out-of-Pocket Maximum
The out-of-pocket maximum is another important number.
For Marketplace plans, the out-of-pocket limit applies to covered services and generally limits what you pay during a plan year for deductibles, copayments, and coinsurance for covered in-network care. Premiums and certain other expenses are not included.
For 2026, HealthCare.gov lists Marketplace maximum out-of-pocket limits of $10,600 for an individual and $21,200 for a family.
Check the Provider Network
Before choosing a plan, verify that your preferred doctors, hospitals, clinics, and specialists are included in the network.
A plan may have attractive pricing but become less useful if your preferred healthcare providers are out of network.
Health insurance plans can use different network structures, including HMOs and PPOs. Marketplace plan categories can include different network types.
Review Prescription Coverage
If you take prescription medication regularly, check the plan’s drug formulary.
Look at whether your medications are covered, which tier they occupy, and whether you must use a particular pharmacy.
Prescription costs can differ substantially between plans, so this step should not be overlooked.
Compare Different Plan Categories
Marketplace plans are commonly divided into Bronze, Silver, Gold, and Platinum categories. These categories describe how you and the insurance company generally share healthcare costs; they are not ratings of the quality of healthcare.
A lower-level plan may have lower premiums but higher costs when you receive care. A higher-level plan may have higher premiums but lower costs when you use healthcare.
Consider Your Expected Healthcare Needs
Think about how often you visit doctors, whether you take prescription medication, whether you expect surgery or treatment, and whether you have ongoing healthcare needs.
Someone who rarely uses healthcare may evaluate plans differently from someone who expects frequent specialist visits.
Final Thoughts
Choosing health insurance requires looking beyond the monthly premium. Compare premiums, deductibles, copayments, coinsurance, out-of-pocket limits, provider networks, prescription coverage, and expected medical needs.
Take time to read the plan documents before enrolling. Understanding the costs in advance can make it easier to budget for healthcare throughout the year.
