Understanding Deductibles
A deductible is the amount you pay for covered health care services before your insurance plan starts to pay. When comparing plans, note whether the deductible applies to all services or only to certain categories, such as hospital stays or prescription drugs. A plan with a lower premium often has a higher deductible, so consider how much you can afford to pay out of pocket before coverage begins. Also check if the plan aggregates family deductibles differently, as some plans require each family member to meet an individual deductible before the family deductible is satisfied.
Evaluating Co-pays and Coinsurance
Co-pays are fixed amounts you pay for specific services, such as a doctor visit or a specialist consultation. Coinsurance is the percentage of costs you pay after you’ve met your deductible. Plans vary in how they structure these cost-sharing features. For example, one plan may have a $30 co-pay for primary care visits and 20% coinsurance for hospitalizations, while another may have a $50 co-pay and 30% coinsurance. Compare these rates across the services you anticipate using most, as a plan with a lower premium might have higher cost-sharing that increases your overall spending.

Out-of-Pocket Maximums
The out-of-pocket maximum is the most you have to pay for covered services in a plan year. After you reach this amount, the plan pays 100% of covered benefits. This limit includes deductibles, co-pays, and coinsurance, but typically does not include premiums. A plan with a lower out-of-pocket maximum provides greater financial protection if you experience high medical costs. When comparing plans, consider how this limit interacts with the deductible and cost-sharing structure. For example, a high-deductible plan may also have a high out-of-pocket maximum, which could strain your budget in a year with significant health needs.
Network Restrictions
Plans often have networks of doctors, hospitals, and other providers. In an HMO, you typically must use providers within the network except in emergencies; a PPO offers more flexibility but often at a higher cost. Some plans cover out-of-network care at a reduced rate or not at all. Verify that your current doctors and preferred hospitals are in the plan’s network, and check how the plan handles referrals to specialists. If you travel frequently or have dependents in different locations, a plan with a broader network may save you unexpected expenses.

Prescription Drug Coverage
Review the plan’s formulary—the list of covered prescription drugs—to see if your medications are included and at what tier. Drugs in lower tiers generally have lower co-pays or coinsurance. Some plans require prior authorization or step therapy, which means you must try a lower-cost drug before a more expensive one is covered. Pay attention to any coverage restrictions, such as quantity limits or mandatory mail-order pharmacy use. If you take regular medications, the difference in drug coverage between plans can substantially affect your total costs.

Practical Comparison Checklist
Use this checklist when reviewing plan documents side by side:
- Premium: What is the monthly cost for coverage?
- Deductible: What is the annual amount you must pay before the plan starts sharing costs? Does it apply to all services?
- Co-pays and Coinsurance: What are the fixed co-pays for primary care, specialists, urgent care, and emergency room visits? What is the coinsurance rate for hospital stays or other major services?
- Out-of-pocket maximum: What is the maximum you could pay for covered services in a year?
- Network: Are your preferred doctors, hospitals, and pharmacies in-network? What is the cost for out-of-network care?
- Prescription drugs: Is each of your medications on the formulary? At what tier? Are there any access limits or special requirements?
- Additional benefits: Does the plan offer dental, vision, or wellness programs? Are there any coverage exclusions for conditions you have?
Completing this checklist for each plan will clarify which option best fits your health needs and financial situation.
