Understand coverage before choosing a plan
Health Insurance Basics
What Is Health Insurance?
Health insurance is designed to help cover eligible healthcare expenses in exchange for a premium and, depending on the plan, other forms of cost sharing. Instead of paying every covered medical bill entirely on your own, you and the health plan share eligible costs according to the policy or plan's rules.
That cost sharing can include a deductible, copayments and coinsurance. A plan can also have an out-of-pocket maximum for covered services. These terms matter because the monthly premium is only one part of what healthcare coverage can cost you.
Health insurance also involves rules about providers, covered services, prescriptions and when certain services require authorization or referrals. The exact details depend on the plan, the market in which you receive coverage and the policy documents.
Premium: The amount paid for health insurance coverage, generally on a monthly basis.
Deductible: What you generally pay for certain covered services before the plan begins paying its share.
Out-of-pocket maximum: A limit on what you pay for covered services during a plan year, subject to the plan's rules.
The Four Cost Terms
Know What You Actually Pay
Understanding the difference between premium and out-of-pocket costs is essential when comparing health insurance plans.
Premium
The recurring amount you pay to maintain health insurance coverage, whether or not you use healthcare services.
Deductible
The amount you generally pay for covered services before your plan starts paying its share, with exceptions for certain services.
Copayment
A fixed dollar amount you pay for a covered healthcare service, depending on your plan's cost-sharing rules.
Coinsurance
A percentage of the allowed cost of a covered service that you pay after meeting the applicable deductible.
Plan Structures
Common Health Insurance Plan Types
Plan names describe how coverage is organized. The actual benefits, provider network, referrals and cost sharing must always be checked in the specific plan documents.
HMO — Health Maintenance Organization
HMO plans generally use a defined provider network and may have rules around selecting a primary care provider or obtaining referrals for certain specialist care.
- Network structure matters
- Referral rules may apply
- Check out-of-network coverage carefully
PPO — Preferred Provider Organization
PPO plans generally provide a network of preferred providers and may offer coverage for some out-of-network care, often at a higher cost than in-network care.
- Provider network is important
- Out-of-network options may exist
- Compare cost differences carefully
EPO — Exclusive Provider Organization
EPO plans generally limit coverage to providers within the plan's network except where the plan allows otherwise, such as certain emergency situations.
- Network restrictions can be significant
- Check doctors before enrolling
- Review emergency-care rules
POS — Point of Service
POS plans combine characteristics of managed-care arrangements and may use different cost-sharing rules depending on whether you use in-network or out-of-network providers.
- Network choice affects cost
- Referral rules may apply
- Read plan-specific requirements
Marketplace Plan Categories
Bronze, Silver, Gold & Platinum
Marketplace metal categories are designed to help compare how plan costs are generally divided between the enrollee and the plan. The category is not a rating of the quality of medical care.
Choosing a Plan
Do Not Compare Health Plans by Premium Alone
HealthCare.gov recommends considering estimated total yearly costs because deductibles, copayments, coinsurance and other out-of-pocket costs can significantly affect the overall cost of coverage. :contentReference[oaicite:1]{index=1}
Check Your Doctors
If you have a preferred doctor, specialist or hospital, check whether they participate in the plan's network. Network rules can materially affect your costs.
Review Prescription Coverage
If you regularly use prescription medicines, review the plan's drug coverage and applicable cost-sharing rules before choosing a plan.
Estimate Healthcare Use
Think about expected doctor visits, prescriptions, specialist care and other healthcare needs when comparing estimated annual costs.
Look at the Worst-Case Cost
Review the plan's out-of-pocket maximum for covered services. It can be an important part of understanding financial exposure during a high-use year.
A Simple Comparison Method
How to Evaluate a Health Insurance Plan
Use a consistent process so that two plans can be compared on more than just their monthly premium.
1
Start With Coverage
Check the services, prescriptions and healthcare needs that matter most to your household.
2
Check the Network
Confirm whether your preferred doctors, hospitals and specialists are included.
3
Compare Total Costs
Consider premium, deductible, copays, coinsurance and the out-of-pocket maximum together.
4
Read the Details
Review the plan documents, limitations, exclusions and rules before making a final choice.
What Is an Out-of-Pocket Maximum?
An out-of-pocket maximum is the most you generally pay for covered services in a plan year after meeting the plan's applicable rules. HealthCare.gov explains that once you reach the applicable limit for covered in-network services, the plan generally pays 100% of covered benefits for the remainder of the plan year. Premiums, non-covered services and certain out-of-network costs are not included in the out-of-pocket maximum. :contentReference[oaicite:2]{index=2}
For 2026 Marketplace plans, the federal limit cannot exceed $10,600 for an individual or $21,200 for a family. Individual plans can have lower limits, so the actual plan documents should always be checked. :contentReference[oaicite:3]{index=3}
