Overview
Open enrollment is the period when you choose or change employer-sponsored and individual health coverage for the coming plan year. Rules and choices can affect your monthly premium and how much you pay when you need care, so reviewing options carefully is important before you enroll.
This guidance explains what to compare, common pitfalls, and practical next steps to pick the best value plan for your household.
Key takeaways
- Make sure your preferred doctors and pharmacy are in the plan’s network to avoid higher out-of-pocket costs.
- Compare total expected costs—premiums, deductibles, copays, coinsurance, and out-of-pocket maximums—rather than choosing by premium alone.
- If employer coverage is not available or not suitable, you can shop individual plans through state or federal marketplaces.
- Gather needed documents and act before the enrollment deadline to avoid gaps in coverage.
How it works
Employers may offer group health plans, and many people can also buy individual coverage through insurance carriers or the public insurance exchange where available. Each plan describes who is eligible, what providers are in-network, covered services, and cost-sharing rules.
Provider networks matter: with an HMO you typically pay only for in-network care except in emergencies, while PPO plans may allow out-of-network care at a higher cost. For background on federal coverage changes and enrollment timing, see Affordable Care Act and Open Enrollment.
Plan costs include the monthly premium plus any deductible, copays for visits, coinsurance for services after the deductible, and the plan’s out-of-pocket maximum. Run a few care-use scenarios—low, moderate, and high—to estimate your annual expenses under each plan.
What it may cover (and what it may not)
Most comprehensive health plans cover preventive care, primary care visits, hospital services, emergency care, prescription drugs, and behavioral health services, though the details vary by plan and tier.
Some services may require prior authorization, have limits, or be excluded; for example, cosmetic procedures and certain elective services may not be covered. Coverage for dependents depends on the plan’s eligibility rules, and employer plans differ on whether spouses are eligible.
Common mistakes to avoid
- Assuming the lowest premium is the cheapest overall—high deductibles or coinsurance can raise total cost if you need care.
- Not checking whether your current specialists, hospital, or preferred pharmacies are in-network.
- Overlooking the out-of-pocket maximum, which caps your annual spending for covered services.
- Missing changes to plan formularies that affect the cost or coverage of your prescriptions.
- Failing to report life changes (marriage, birth, loss of other coverage) that may qualify you for a special enrollment period.
Questions to ask an agent
Ask whether a plan covers your current doctors and whether prior authorization is commonly required for procedures you may need.
Request clear examples of out-of-pocket costs for typical care you expect to use, including primary care visits, specialist visits, and common prescriptions.

Next steps
Collect plan materials, a current list of your medicines, and contact information for your doctors and pharmacy before you compare options.
Estimate costs under each plan using scenarios (few visits, chronic-care management, and a major health event) so you can compare true value, not just premiums.
If you prefer personalized help reviewing choices, talk to an agent who can explain plan terms and enrollment requirements.
Frequently Asked Questions
Do I have to sign up for coverage during open enrollment?
If you want employer or individual coverage for the next plan year, you typically must enroll during open enrollment unless you qualify for a special enrollment period due to a life event.
How can I check whether my doctor is in a plan’s network?
Use the insurer’s online provider search or call the plan’s customer service to confirm your doctor and hospital are listed as in-network providers.
Should I choose a plan with a low premium or low deductible?
Choose based on your expected health care use: a low premium may save money if you need little care, while a lower deductible and lower cost-sharing can be better if you expect regular or costly services.
What documents do I need to enroll?
Typical items include names and birthdates for household members, Social Security numbers or document numbers for eligible dependents, and details about current prescriptions and providers.
