How To Apply For Health Insurance

Health insurance companies charge you based on your circumstances and the policy you choose. They are also an essential resource to many people who need help affording health care and medical costs. According to KFF’s 2025 Employer Health Benefits Survey, the average annual premium for employer-sponsored family coverage reached $25,572 in 2025, which is why choosing the right plan matters so much.

If you already have health insurance, the first priority is reading and understanding what the policy actually covers. Some people discover they are underinsured only after a serious claim, they assumed they were covered, then found out their plan excluded large categories of care. That kind of surprise is expensive. The Centers for Medicare and Medicaid Services (CMS) requires all ACA-compliant plans to provide a standardized Summary of Benefits and Coverage document, which makes plan-to-plan comparison more straightforward than it used to be.

Procedures for applying for health insurance:

Contact the insurance company.
If you do not know anyone at the company, go online or search the company’s website for information about the benefits you are applying for. Major insurers such as UnitedHealthcare, Blue Cross Blue Shield, Aetna, and Cigna all maintain online portals where you can review plan details and begin an application. You can also use the federal HealthCare.gov application portal if you are seeking an ACA Marketplace plan. You will likely be required to provide personal information, so have it ready before you start.

The application form.
Have the application form ready before your appointment. Fill it out completely and accurately, incomplete forms are one of the most common reasons applications are delayed. If you are asked to provide documents such as a government-issued photo ID, proof of citizenship or legal residency, or income documentation like a W-2 or recent tax return, bring those along with the completed form. The HealthCare.gov enrollment guide provides a full checklist of required documents before you begin.

One important caution: accuracy on the application is not optional. Errors in reported household income or dependent information can result in incorrect premium tax credit amounts. If your credits are overcalculated, the IRS will require repayment when you file your taxes, sometimes an unexpected bill of several hundred dollars or more. The IRS Premium Tax Credit guidelines explain how reconciliation works and what to do if your income changes during the year.

Obtaining claim forms from the doctor and hospitals you have visited. If you have visited doctors or hospitals recently, obtain the claim forms from them. This helps you track expenses related to those visits and ensures your records are consistent with what you report on your application. The CMS-1500 claim form is the standard form used by most non-institutional healthcare providers and suppliers for billing purposes.

Proof of address.
Proof of address shows the insurer that you actually live in the coverage area you claim. Insurers use this to prevent premium fraud from applicants who falsely claim a different residence. Acceptable documents typically include a utility bill, a bank statement, or a government-issued document showing your current address. Statements from institutions such as Chase, Bank of America, or your local credit union are widely accepted.

The right amount of premium.
Premiums vary significantly depending on your age, location, plan type, and household size, so comparing options before committing is worth the time. Tools such as the HealthCare.gov Plan Finder and resources from the National Association of Insurance Commissioners (NAIC) allow side-by-side plan comparisons so you can evaluate premiums, deductibles, and out-of-pocket maximums before enrolling.

The proper form.
Insurance companies have their own processes for handling applications. They often require documents in specific formats, and application materials may not be available at a general retailer or local office supply store. If you cannot find your specific form online, contact the insurer directly and ask whether they can provide it in person. State insurance regulators, overseen at the federal level by the Department of Health and Human Services (HHS), require that all insurers make application materials clearly available to consumers.

The right location.
You may apply directly through a licensed insurer’s office, through the federal HealthCare.gov Marketplace, or through your state’s own exchange (such as Covered California, NY State of Health, or GetCoveredNJ). If you apply at a local office, be sure to bring proof of residence. Working with a certified navigator or broker, resources listed through the CMS Navigator Program, can help you avoid enrollment errors that are easy to make when reading plan documents for the first time.

Many consumers miss out on subsidy money simply because they do not realize they qualify. Anyone shopping for coverage should check eligibility for premium tax credits through the ACA Marketplace before assuming employer-sponsored or private direct insurance is their only option. The IRS Premium Tax Credit guidelines explain the income thresholds and how to estimate your credit before you apply.

Protecting your identity.
Health insurance applications require sensitive personal data including your Social Security Number (SSN), date of birth, and household income. Submit applications only through secure, verified portals, as the Federal Trade Commission (FTC) recommends. If your identity is stolen, strangers could make claims in your name and access your benefits before you are even aware of the breach. Monitoring services such as Experian IdentityWorks, or free annual credit reports available at AnnualCreditReport.com under the Fair Credit Reporting Act (FCRA), give you early warning if something is wrong.

Advantages of Health Insurance Companies

Under the ACA, insurers cannot deny coverage or charge higher premiums based on pre-existing conditions, a protection enforced by HHS and confirmed by KFF’s pre-existing condition research. This matters for anyone recently diagnosed with a chronic illness or recovering from a serious condition who might otherwise face inflated rates or outright rejection in an unregulated market.

Health insurance is still available even if you lose your job or income. You can get coverage through the ACA Marketplace during a Special Enrollment Period, through COBRA continuation coverage (which lets you keep your employer plan for up to 18 months), or through Medicaid if your income qualifies. The Department of Labor (DOL) COBRA information page explains your rights and timelines in full. Keep in mind that COBRA requires you to pay the full premium, both the portion you paid as an employee and the portion your employer covered, plus a 2% administrative fee, which can make it considerably more expensive than Marketplace alternatives.

Most major insurers including UnitedHealthcare, Humana, and Blue Cross Blue Shield maintain round-the-clock member services lines and digital chat support, so help is available when you need to resolve billing disputes or coverage questions quickly.

Many plans now include telehealth services at no additional cost, a trend accelerated since 2020 and documented by the Peterson-KFF Health System Tracker. For minor illnesses or prescription renewals, this can save both time and money compared to an in-person visit.

Coverage typically extends across a wide range of specialists, from dermatologists and podiatrists to ophthalmologists and family physicians, depending on your plan type and whether dental or vision riders are included. Dental and vision are not standard in most ACA Marketplace plans for adults, so review those details carefully before enrolling.

Many insurers offer care management programs, nurse hotlines, and second-opinion services at no additional cost to members, which can be genuinely useful when navigating a new diagnosis or complex treatment decision.

Networks are regulated by state insurance commissioners and must meet adequacy standards set by CMS for plans sold on the ACA Marketplace, which means your covered services must be accessible through a qualified group of hospitals, doctors, and specialists, not just technically listed on a provider directory.

Under Section 1557 of the ACA, insurers receiving federal funding must provide meaningful language access to individuals with limited English proficiency, which means bilingual staff or qualified interpreter services are a legal requirement, not just a courtesy.

Many plans include formulary drug lists with tiered copays, and programs like GoodRx work alongside insurance coverage to reduce out-of-pocket prescription costs further.

Some insurers, particularly Medicare Advantage plans offered through companies like Humana and Aetna, include supplemental wellness benefits such as gym memberships or discounted event tickets as part of their member perks. These extras vary widely by plan and region, so do not treat them as guaranteed when comparing options.

Select Medicare Advantage plans now include allowances for healthy food purchases, a benefit tracked by the KFF Medicare Advantage Benefits Report.

Even if you are healthy and not currently facing any medical problems, regular check-ups are worth scheduling. Unexpected things can happen at any time. Under the ACA, all Marketplace and most employer-sponsored plans are required to cover preventive services at no cost to the patient, including annual wellness exams, blood pressure screenings, and recommended vaccinations, as outlined by the HealthCare.gov preventive care page. Catching a problem early through a routine screening is almost always cheaper and less disruptive than treating it after symptoms appear.

Frequently Asked Questions

When can I apply for health insurance?

You can apply for ACA Marketplace health insurance during the annual Open Enrollment Period, which runs from November 1 through January 15 for most states. Outside of that window, you may qualify for a Special Enrollment Period if you experience a qualifying life event such as losing job-based coverage, getting married, having a baby, or moving to a new coverage area. Medicaid and CHIP applications are accepted year-round with no enrollment window restrictions.

What documents do I need to apply for health insurance?

You typically need a government-issued photo ID, your Social Security Number (SSN), proof of current address (such as a utility bill or bank statement), proof of income (such as a W-2 form or recent pay stubs), and immigration documentation if applicable. Employer plan enrollments may also require a qualifying event notice. The HealthCare.gov document checklist provides a complete list before you begin your application.

How much does health insurance cost per month?

The average monthly premium for an individual ACA Marketplace plan before subsidies is approximately $477, according to CMS enrollment data. Most enrollees receive premium tax credits that significantly reduce this amount, after subsidies, the average enrollee pays closer to $111 per month. Costs vary based on age, location, plan tier (Bronze, Silver, Gold, or Platinum), tobacco use, and household size.

What is the difference between a deductible and a premium?

A premium is the monthly amount you pay to maintain your health insurance coverage, regardless of whether you use any medical services. A deductible is the amount you must pay out of pocket for covered health services before your insurance plan begins sharing costs. If your plan has a $2,000 deductible, you pay the first $2,000 of covered medical costs each year before your insurer contributes. After the deductible is met, cost-sharing through copays and coinsurance applies until you reach your out-of-pocket maximum.

What is a Health Savings Account (HSA) and who qualifies?

A Health Savings Account (HSA) is a tax-advantaged savings account available to individuals enrolled in a qualifying High-Deductible Health Plan (HDHP). Contributions are tax-deductible, grow tax-free, and can be withdrawn tax-free for qualified medical expenses. For 2026, the IRS contribution limit is $4,300 for individuals and $8,550 for families. HSAs are offered through many financial institutions including Fidelity, HSA Bank, and Chase. You cannot have an HSA if you are enrolled in Medicare or claimed as a dependent on someone else’s tax return.

Can I get health insurance if I have a pre-existing condition?

Yes. Under the Affordable Care Act (ACA), insurance companies are legally prohibited from denying coverage or charging higher premiums based on pre-existing conditions such as diabetes, cancer, heart disease, or asthma. This protection applies to all plans sold on the ACA Marketplace and to most employer-sponsored group health plans, and is enforced by HHS and the Department of Labor (DOL). One important exception: short-term health plans, which are not ACA-compliant, may still impose pre-existing condition exclusions. Read the fine print before enrolling in any plan marketed as “short-term” or “limited benefit.”

What is COBRA and how does it work?

COBRA (Consolidated Omnibus Budget Reconciliation Act) is a federal law administered by the Department of Labor (DOL) that allows you to continue your employer-sponsored health insurance for up to 18 months after leaving a job, having your hours reduced, or experiencing other qualifying events. Under COBRA, you pay the full premium, both the employee and employer share, plus a 2% administrative fee. This can be costly. For many people, a subsidized ACA Marketplace plan will be cheaper than COBRA, so compare both options before defaulting to continuation coverage.

What are the 10 essential health benefits required under the ACA?

The ACA requires all Marketplace plans and most employer plans to cover 10 essential health benefits: ambulatory patient services, emergency services, hospitalization, maternity and newborn care, mental health and substance use disorder services, prescription drugs, rehabilitative services and devices, laboratory services, preventive and wellness services, and pediatric services including dental and vision for children. These requirements are enforced by CMS and outlined in full at HealthCare.gov. Note that adult dental and vision are not included in this list, those require separate riders or standalone plans.

What is Medicaid and do I qualify?

Medicaid is a joint federal and state health coverage program for low-income individuals and families, administered by the Centers for Medicare and Medicaid Services (CMS)., Medicaid covers over 90 million Americans. Eligibility is based primarily on income relative to the federal poverty level (FPL). In states that have expanded Medicaid under the ACA, adults earning up to 138% of the FPL (approximately $20,800 per year for an individual in 2026) qualify. You can apply at any time through your state Medicaid agency or through HealthCare.gov.

How do I compare health insurance plans effectively?

Look beyond the monthly premium. Evaluate the annual deductible, out-of-pocket maximum, and copay structure, and verify that your preferred doctors and hospitals are in-network before enrolling. Use the HealthCare.gov Plan Finder tool or your state exchange’s comparison tool to view side-by-side details. The National Association of Insurance Commissioners (NAIC) also maintains a consumer complaint database that can help you assess insurer reliability before you commit.

Is health insurance worth it if I am young and healthy?

For most young adults, yes, though the math depends on how you use care. The main risk of going uninsured is a single unexpected event: a broken bone, an appendectomy, or an ER visit averages $1,219 out of pocket for the uninsured, according to the Peterson-KFF Health System Tracker. A catastrophic plan (available to adults under 30) offers a low-premium option with high deductibles for exactly this scenario. If your income qualifies you for a subsidized Silver plan with cost-sharing reductions, the catastrophic plan may not actually be cheaper, always run the numbers on the Marketplace before deciding.
