How to Compare Health Insurance Plans During Open Enrollment

EMPLOYEE BENEFITS GUIDE · REVIEWED OCTOBER 21, 2026

Here is how to compare health insurance plans: use the same household needs and cost assumptions for every option. Start with provider access and prescription coverage, then compare annual premiums, cost-sharing and account funding. Finish by checking the enrollment deadline and effective date.

A short, consistent worksheet is more useful than judging each option from a different brochure or choosing the lowest deduction shown in the employee portal.

How to compare health insurance plans during workplace open enrollment
Use the current employer plan documents to confirm your options.

Gather the Same Documents for Each Plan

Get the current Summary of Benefits and Coverage, or SBC, for every option. CMS’s Summary of Benefits and Coverage guidance explains how this standardized document presents key coverage features. Use the full plan materials for details and exceptions.

Also collect the exact network name, prescription drug list, employee premium and employer HSA or other account funding information. Label everything with the applicable plan year and coverage tier.

If you have last year’s materials open, put them aside while comparing the new choices. They can help identify changes, but they should not supply the amounts for your new-year estimate.

List Your Household’s Care Needs

Write down regular providers, hospitals, prescriptions and ongoing treatment. Add foreseeable changes such as a planned procedure, pregnancy-related care or a dependent living in another area.

Separate confirmed needs from possibilities. A planned appointment can help you estimate routine spending, while an uncertain major event belongs in a separate higher-care scenario.

For each important need, record what you must verify. The goal is not to predict every expense; it is to prevent an important coverage question from disappearing behind a premium comparison.

Verify Networks and Drug Coverage

HealthCare.gov’s plan-type guide describes differences among network arrangements. Use your actual plan directory to check providers and ask the plan about any uncertainty. A provider may participate in one carrier network and not another.

For prescriptions, check the exact medication and prescribed use. Review the tier, authorization requirements and pharmacy rules. A carrier’s general drug page is not confirmation of coverage under every employer plan.

If GLP-1 treatment is part of your household’s care, confirm the benefit and any exclusions directly with the plan or pharmacy benefit manager before enrolling.

Calculate the Annual Employee Premium

Use the number of payroll deductions, not an assumed 12-month multiplier when the amount is quoted per paycheck. For example, $125 over 24 deductions is $3,000 annually. That example is hypothetical.

Record the coverage tier alongside the total. Employee-only and family premiums cannot be compared as if they purchase the same coverage.

Ask whether the displayed amount includes any applicable surcharge or credit. Keep optional dental, vision or supplemental premiums separate until you total the complete benefits package.

Compare Costs When You Use Care

Review deductibles, copays, coinsurance and the in-network out-of-pocket maximum. Identify separate prescription or out-of-network amounts and ask which services are covered before the deductible.

Estimate a routine year under each option, then a year with substantial covered care. Use the same services or spending scenario for each comparison.

Include employer account funding and its timing, while keeping your own account contributions distinct from employer-paid money. Label estimates clearly so they are not mistaken for a promised bill.

Check Practical Requirements

Ask about referrals, prior authorization, service-area restrictions and care away from home. Consider how each option would work for the providers and family members on your list.

Review any plan replacement notice and confirm when the new coverage starts. If you are changing carriers, ask when member identification and online account information become available.

Save the plan documents and important coverage answers where you can find them after enrollment.

Submit and Confirm Your Election

Once you choose, review dependents and all benefit elections before submitting. Save the final confirmation and check the employer’s next-year summary. A comparison worksheet is not an enrollment submission.

Employees should direct specific plan questions to their benefits team. Employers seeking help explaining the available options can explore ESI’s employee benefits services. Consistent comparison materials make the decision easier to understand and complete.

A PRACTICAL NEXT STEP

Use the Same Checklist for Every Plan

  • Gather the current SBC for each plan option.
  • Check doctors, hospitals and prescription coverage.
  • Calculate annual payroll contributions.
  • Compare deductibles, copays, coinsurance and limits.
  • Model routine and substantial-care scenarios.

Common Questions

Is the Lowest Premium Always the Cheapest Plan?

No. Premiums are only one part of cost. Expected care, cost-sharing and provider access can change the overall value.

Where Can I Find a Plan’s SBC?

Ask the employer or plan administrator for the current Summary of Benefits and Coverage for each offered option.

Should I Check GLP-1 or Other Prescription Coverage?

Yes, if a medication matters to your household. Check the exact drug, use, authorization rules and plan year directly with the plan or pharmacy benefit manager.
