Overview
The Affordable Care Act (ACA) changed how individuals and many employers obtain health insurance by creating organized marketplaces, standardizing certain benefits, and expanding consumer protections.
This article explains how those marketplace choices and protections affect individuals, small businesses, and people who buy insurance on their own.
Key takeaways
- Most people can shop for individual and family plans through state or federal health insurance marketplaces during open enrollment.
- Employers of a certain size have options about offering group coverage or allowing employees to use marketplace plans with potential employer contributions.
- Premium tax credits are available to eligible people based on income, which can lower monthly costs.
How it works
Health insurance marketplaces collect plans from different insurers and display them with standardized information so consumers can compare premiums, deductibles, provider networks, and covered benefits.
Coverage choices and eligibility for premium assistance depend primarily on household size and income, while plan tiers (bronze, silver, gold, platinum) indicate relative levels of cost-sharing.

What it may cover (and what it may not)
Marketplace plans must include a set of essential health benefits such as hospitalization, prescription drugs, maternity care, mental health services, and preventive care.
However, coverage limits, provider networks, prior-authorization rules, and out-of-pocket maximums vary by plan, and some services may have separate cost-sharing or not be covered if they fall outside the essential benefits package.
Common mistakes to avoid
Do not assume the lowest premium is the best value; check deductibles, co-payments, and whether your preferred doctors are in-network.
Avoid missing enrollment deadlines — special enrollment periods apply only for qualifying life events such as loss of coverage, marriage, or birth of a child.
Questions to ask an agent
Ask about plan networks and whether your current doctors and pharmacies are included in the plan you are considering.
Confirm how cost-sharing works for typical services you use, such as primary care visits, specialist care, prescription medications, and hospital stays.
Ask whether your household income would qualify for premium tax credits or cost-sharing reductions and how those credits affect plan choices.
Next steps
Compare available plans side-by-side for premiums, deductibles, provider networks, and covered services before enrolling.
Small business owners who want information on employer responsibilities and small-group options can review Affordable Care Act and Health Coverage Options for Small Businesses to understand how offering coverage interacts with marketplace options.
If you provide or coordinate home health services and need coverage guidance specific to that work, see Home Health Care and Nurse Registries Insurance for specialty considerations.
If you prefer personal help to compare plans and assess eligibility, talk to an agent who can review options and next steps with you.
Frequently Asked Questions
Will I be able to keep my current plan?
Some people can keep their current plans if the insurer continues to offer them, but plan availability varies by location and insurer participation in the marketplace.
How do premium tax credits work?
Premium tax credits lower monthly premiums for eligible people based on income and household size and are applied when you enroll or claimed when you file taxes.
Can employers require employees to use the marketplace?
Employer obligations depend on employer size and applicable regulations; employers may offer group plans, contribute toward individual coverage, or allow marketplace enrollment in some cases.
What if I miss open enrollment?
If you miss open enrollment, you generally must wait until the next enrollment period unless you qualify for a special enrollment period due to certain life events.
