Use this checklist to review your current coverage, estimate next year's costs, and choose a health plan with confidence.

Key Takeaways

Reviewing last year's medical spending helps you estimate what coverage level you actually need.
Your list of current prescriptions is one of the most important documents to have on hand.
Confirming that your preferred doctors are in-network can prevent costly out-of-network bills.
Understanding the difference between premiums and out-of-pocket costs is essential before comparing plans.
Life changes like marriage, a new baby, or a job change may affect your eligibility and best plan choice.

Why Preparation Makes Open Enrollment Less Overwhelming

Open enrollment — the annual window when you can sign up for or change your health insurance — tends to arrive with little fanfare and a tight deadline. Most people either rush through it or simply re-enroll in whatever they had last year without a second look. Neither approach serves you well.

The goal of this checklist is to help you walk into the enrollment process with everything you need already in hand. When you know your real costs from last year, have your prescriptions listed, and understand the difference between a premium and an out-of-pocket maximum, comparing plans becomes a lot more straightforward.

Once you have selected a plan, our guide to getting the most out of your health coverage can help you use your benefits effectively throughout the year.

This Is General Information, Not Personal Advice

This checklist provides general educational guidance about health insurance enrollment. It is not personalized insurance, financial, or legal advice. Coverage terms, costs, and eligibility rules vary by plan, employer, and state. Read your actual plan documents carefully and consult a licensed insurance agent or benefits advisor for guidance specific to your situation.

What to Gather and How to Use This Checklist

Work through the checklist groups below before you open any plan comparison tool. Gathering your documents first saves time and prevents you from making decisions based on guesswork.

Required

Summary of Benefits and Coverage (SBC)

A standardized document required by federal law that lays out each plan's key costs and coverage in plain language — your primary comparison tool.

Required

Explanation of Benefits (EOB) statements

Past EOBs show what your insurer paid versus what you owed, helping you gauge how much care you actually used last year.

Required

Plan formulary (drug list)

Each insurer publishes a list of covered medications organized by cost tier; use it to verify your prescriptions are covered.

Required

Provider directory

Your insurer's searchable list of in-network doctors, specialists, and hospitals — essential for confirming your care team stays covered.

Optional

Healthcare.gov or your state Marketplace

The official enrollment platform for individuals and families buying coverage outside of an employer, including subsidy eligibility tools.

Optional

Spreadsheet or comparison worksheet

A simple side-by-side grid helps you compare premiums, deductibles, and out-of-pocket maximums across multiple plans without losing track.

Start with your records and spending history, then move through life changes and plan evaluation. If you are enrolling dependents, make sure you have their information — including their medications and preferred providers — ready as well.

Documents and Records to Pull Together

Locate your current health insurance card and Summary of Benefits and Coverage (SBC) document so you know exactly what your existing plan covers. Must

Pull together any Explanation of Benefits (EOB) statements from the past 12 months to see what you actually used and paid. Must

Write down every prescription medication you and your covered family members take, including dosage, so you can verify each plan's drug formulary. Must

List the names of your primary care doctor, specialists, and any preferred hospitals to confirm in-network status under prospective plans. Must

Note any upcoming procedures, planned pregnancies, or anticipated specialist visits so you can factor those costs into your plan comparison. Should

Understanding Your Current Costs

Add up your total out-of-pocket medical spending from last year — copays, coinsurance, and deductible payments — to establish a realistic baseline. Must

Identify your current monthly premium and annual deductible so you have a clear comparison point when evaluating new plan options. Must

Check whether you hit your out-of-pocket maximum last year; if so, a plan with a lower maximum may be worth paying a higher premium. Should

Review your household budget to determine how much you can realistically afford in monthly premiums versus higher cost-sharing when care is needed. Should

Life Changes That Affect Your Decision

Note any qualifying life events from the past year — marriage, divorce, a new baby, or adoption — that may change who needs coverage under your plan. Must

Confirm whether a spouse or domestic partner gained or lost employer-sponsored coverage, which affects whether you need individual or family enrollment. Must

Check whether any dependents are aging off your plan (typically at age 26) and need their own coverage. Should

If your income or employment status changed, determine whether you may now qualify for subsidies through the Marketplace or for Medicaid. Should

Evaluating Plan Options

Compare each plan's premium, deductible, copays, coinsurance, and out-of-pocket maximum side by side — not just the monthly cost. Must

Verify that your current prescriptions appear on each plan's drug formulary and note which cost tier they fall under. Must

Confirm your preferred providers are listed as in-network under each plan you are seriously considering. Must

If a High Deductible Health Plan (HDHP) is available, check whether you are eligible to open a Health Savings Account (HSA) and factor potential tax savings into your cost estimate. Should

Review each plan's mental health, dental, and vision benefits — or lack thereof — so you are not caught off guard by gaps. See our article on common coverage assumptions that lead to surprise bills. Nice to have

A note on costs: the monthly premium is what you pay to have coverage. The deductible is what you pay out of pocket before most benefits kick in. Copays and coinsurance are your share of the cost each time you receive care. The out-of-pocket maximum is the most you will ever pay in a given year — after that, your plan covers 100%. Understanding these terms side by side is the foundation of any smart plan comparison.

Don't Rely on Last Year's Plan Details

Insurers frequently change premiums, deductibles, formularies, and provider networks each year — even if you re-enroll in the same plan. Always download the current plan year's SBC and formulary before making a decision. Assuming nothing changed is one of the most common and costly enrollment mistakes.

Missing the Enrollment Window Has Real Consequences

Open enrollment windows are strict. If you miss yours, you generally cannot enroll or switch plans until the next year unless you experience a qualifying life event. Mark the dates on your calendar well in advance and do not leave your decision to the final day.
