The health insurance marketplace connects millions of Americans with affordable coverage options each year. You can enroll through healthcare.gov or your state’s marketplace, compare plans side-by-side, and find out if you qualify for financial assistance to lower your monthly premiums.
Understanding the Health Insurance Marketplace
The marketplace is your one-stop shop for health insurance. Created under the Affordable Care Act, it offers a standardized way to shop for coverage, compare prices, and access subsidies based on your income.
You’ll encounter two types of marketplaces. The federal marketplace at healthcare.gov serves 32 states. State-based marketplaces like Connect for Health Colorado operate in 18 states plus Washington D.C. Both follow the same basic rules but may have different enrollment periods and assistance programs.
| Marketplace Type | Number of States | Website Example | Key Features |
|---|---|---|---|
| Federal | 32 | healthcare.gov | Centralized platform, uniform dates |
| State-Based | 18 + D.C. | connectforhealthco.com | Extended enrollment, local assistance |
Every marketplace plan covers ten essential health benefits. These include doctor visits, emergency care, prescription drugs, mental health services, and preventive care at no cost to you. Plans are organized into metal tiers—Bronze, Silver, Gold, and Platinum—that indicate how you and your insurance split costs

How to Navigate Healthcare.gov Step-by-Step
Start by creating an account on healthcare.gov. You’ll need an email address and basic information about your household. The site walks you through each section, but preparation helps you move faster.
First, gather your documents. You’ll need Social Security numbers for everyone applying, income information from recent pay stubs or tax returns, and current health insurance policy numbers if you have coverage. For self-employed individuals, bring your most recent tax return showing business income.
The application asks about household size and income. Be accurate here because these numbers determine your subsidy eligibility. Household includes you, your spouse, and any dependents you claim on taxes. Income means your modified adjusted gross income—basically your adjusted gross income with some additions.
After you submit your application, you’ll see if you qualify for premium tax credits or cost-sharing reductions. Premium tax credits lower your monthly payment. Cost-sharing reductions decrease what you pay when you use care, but only Silver plans offer them.
Browse available plans in your area. Filter by monthly premium, deductible, and provider network. Check if your current doctors accept the plan. Review the prescription drug formulary to confirm your medications are covered.
Select a plan and complete enrollment. You’ll choose a start date and payment method. Most insurers require your first premium payment before coverage begins.
State-Based Marketplaces: Connect for Health Colorado Example
State marketplaces often provide more flexibility than the federal platform. Connect for Health Colorado serves as a strong example of how state exchanges enhance the enrollment experience.
Colorado residents use connectforhealthco.com instead of healthcare.gov. The state runs its own call center with bilingual staff who understand local insurance markets. You can speak with someone familiar with Colorado-specific Medicaid rules and regional insurance carriers.
Connect for Health Colorado extends its special enrollment period for qualifying life events. If you lose job-based coverage, move to Colorado, or have a baby, you get 60 days to enroll instead of the standard window. The state also offers SEP for certain income changes.
In-person assistance is more accessible through state marketplaces. Colorado funds storefront locations across the state where you can meet face-to-face with certified assisters. These offices stay open beyond standard business hours during peak enrollment.
Other state marketplaces operate similarly. California’s Covered California, New York State of Health, and Massachusetts Health Connector each add state-specific programs and extended support options.
Finding In-Person Assistance for Marketplace Enrollment
You don’t have to navigate the marketplace alone. Free help is available through several programs funded by CMS and state governments.
Navigators receive federal grants to provide free enrollment assistance. They’re trained and certified to help you understand options, complete applications, and choose plans. Find navigators through the CMS localhelp.healthcare.gov tool or your state marketplace website.
Certified Application Counselors work through community organizations like health centers, hospitals, and social service agencies. They complete the same training as navigators. Your local community health center probably has CACs on staff.
Insurance agents and brokers can also help you enroll at no charge to you. They’re paid by insurance companies, not by you. Find registered agents through the marketplace website.
Call the marketplace hotline if you prefer phone support. Healthcare.gov operates a call center at 1-800-318-2596 with interpreters for over 150 languages. State marketplaces run their own helplines with local hours.
Schedule an in-person appointment during open enrollment. Assistance programs get busy, so book early. Bring all your documents to make the most of your session. Most appointments last 60-90 minutes.
Comparing Plans and Understanding Your Options
The marketplace shows you every plan available in your county. Understanding how to compare them helps you pick coverage that fits your budget and health needs.
Start with the metal tier. Bronze plans have the lowest monthly premiums but highest out-of-pocket costs when you need care. Platinum plans cost more each month but cover more of your medical bills. Silver plans balance premium and cost-sharing for most people.
Check the provider network next. Insurance companies contract with specific doctors and hospitals. Going outside the network usually means higher costs or no coverage at all. Search the plan’s directory for your current providers.
Look at the prescription drug formulary. Each plan covers different medications at different costs. Find your drugs in the formulary and check which tier they’re in. Tier 1 drugs cost less than Tier 3 or 4 specialty medications.
Compare total costs, not just premiums. Add up your expected doctor visits, medications, and procedures for the year. Calculate what you’d pay in premiums, deductibles, copays, and coinsurance under each plan. The plan with the lowest premium might cost more overall if you use a lot of care.
Review the Summary of Benefits and Coverage. This standardized form shows exactly what each plan covers and what you’ll pay. It’s the same format for every plan, making comparisons easier.
Common Navigation Challenges and Solutions
Most people run into snags during enrollment. Here’s how to fix the most frequent issues.
Income verification problems slow down many applications. The marketplace checks your reported income against IRS and Social Security records. Mismatches trigger requests for documentation. Upload recent pay stubs, tax returns, or a letter from your employer through your marketplace account.
Immigration status questions confuse applicants in mixed-status families. Lawfully present immigrants can get marketplace coverage. Undocumented family members can’t, but you can still apply for eligible household members. The marketplace doesn’t share immigration information with other agencies.
Special enrollment period denials happen when you can’t prove a qualifying event. Getting married, having a baby, or losing other coverage triggers SEP. You need documentation—a marriage certificate, birth certificate, or letter from your old insurer. Upload these documents when you report the life change.
Plan comparison overwhelms many first-time enrollees. Focus on three factors: monthly premium you can afford, whether your doctors are in-network, and total out-of-pocket maximum. Ignore plans that fail any of these tests.
Technical glitches occasionally freeze applications. Save your progress frequently. If the site crashes, wait 24 hours and try again. Call the helpline if problems persist—they can complete enrollment over the phone.
Important Dates and Deadlines for 2025
Missing enrollment deadlines means waiting until next year for coverage. Mark these dates on your calendar.
Open enrollment for 2025 coverage runs from November 1, 2024, through January 15, 2025. This is your main chance to enroll in marketplace insurance or change plans. Some state marketplaces extend this window—California goes until January 31, 2025.
Coverage start dates depend on when you enroll. Sign up by December 15 for January 1 coverage. Enroll between December 16 and January 15 for February 1 coverage. You must pay your first premium for coverage to take effect.
Special enrollment periods happen throughout the year if you have a qualifying life event. You get 60 days from the event to enroll. Qualifying events include losing job-based coverage, moving to a new state, getting married or divorced, having or adopting a child, and losing Medicaid eligibility.
Annual plan changes take effect on January 1 even if you don’t do anything. Your current plan might change benefits or rates. Review your renewal notice carefully. You can switch plans during open enrollment if your plan no longer meets your needs.
After You Enroll: Next Steps
Enrollment isn’t the end of the process. You need to complete a few more tasks before you can use your coverage.
Pay your first premium within the deadline your insurer provides. Most require payment within 14 days of the coverage start date. Your insurance card arrives by mail about 7-10 days after the insurer receives payment.
Activate your online account with your insurance company. This is separate from your marketplace account. You’ll manage claims, find providers, and request ID cards through the insurer’s website.
Understand your coverage details. Read your plan documents to learn about referrals, prior authorization, and how to file claims. Some plans require you to choose a primary care doctor.
Use your coverage. Schedule a free annual checkup. All marketplace plans cover preventive care at no cost—no copay, no deductible. Take advantage of this.
Report life changes to the marketplace within 30 days. Income increases, household size changes, and moves affect your eligibility and subsidies. Update your application to avoid owing money at tax time.
Reconcile your premium tax credit when you file taxes. Form 1095-A shows how much advance credit you received. You’ll settle up with the IRS—getting a refund if you got too little credit or owing money if you got too much.

Frequently Asked Questions
Q: Can I get help applying for marketplace insurance for free?
Yes, navigators, certified application counselors, and registered agents provide free enrollment assistance. Find local help at localhelp.healthcare.gov or call 1-800-318-2596. These services are completely free—never pay someone to help you enroll.
Q: What happens if I miss the open enrollment deadline?
You’ll need to wait until next year’s open enrollment unless you have a qualifying life event that triggers a special enrollment period. Losing job-based coverage, moving, getting married, having a baby, or losing Medicaid eligibility all qualify. You must apply within 60 days of the event.
Q: How do I know if I qualify for financial help with premiums?
Most people with household income between 100% and 400% of the federal poverty level qualify for premium tax credits. For 2025, that’s roughly $15,000 to $60,000 for an individual or $31,000 to $124,000 for a family of four. The marketplace calculates your exact subsidy when you apply.
Q: Can I use healthcare.gov if my state has its own marketplace?
No, you must use your state’s marketplace if your state operates one. Healthcare.gov will redirect you to your state site. Connect for Health Colorado serves Colorado residents, while Covered California serves California residents, and so on for other state marketplaces.
Q: What documents do I need to apply for marketplace coverage?
Bring Social Security numbers for everyone applying, recent pay stubs or tax returns showing income, current health insurance information if you have coverage, and immigration documents if applicable. Self-employed individuals should have their most recent tax return showing business income.
