Quick Answer: Every ACA-compliant health insurance plan sold in 2026 must cover 10 essential health benefit categories, including emergency care, hospitalization, mental health, prescription drugs, and preventive care. How much you pay out-of-pocket depends on your plan tier and income.
If you have ever stared at an Explanation of Benefits and wondered what your plan actually pays for, you are not alone. The Affordable Care Act settled this question for most Americans by requiring every individual and small-group plan to cover a defined set of services. No annual dollar limits. No lifetime caps. Mandatory coverage from day one.
This guide breaks down all 10 essential benefit categories, shows you what plans typically exclude, and explains how your 2026 income determines whether you qualify for a subsidized plan.

The 10 Essential Health Benefits Every ACA Plan Must Cover in 2026
The Affordable Care Act's essential health benefits requirement applies to all non-grandfathered individual and small-group plans. Here is what every compliant plan must include as of 2026.
1. Ambulatory (Outpatient) Patient Services
Doctor visits, urgent care, same-day surgery, and other care you receive without being admitted to a hospital. This is the category that covers your annual physical, specialist appointments, and most routine care.
2. Emergency Services
Emergency room visits must be covered without prior authorization, even if the hospital is out of your plan's network. You cannot be charged more for an out-of-network ER visit than for an in-network one. This applies in all 50 states under federal law.
3. Hospitalization
Inpatient stays, surgery, overnight care, and related services. This includes room and board, nursing care, and procedures performed while you are admitted. There are no annual or lifetime dollar limits on hospitalization coverage under the ACA.
4. Maternity and Newborn Care
Prenatal visits, labor and delivery, and postnatal care are all covered. The ACA reversed decades of practice where many individual plans sold before 2014 excluded maternity care entirely. Newborn care immediately following delivery is also included.
5. Mental Health and Substance Use Disorder Services
Plans must cover mental health treatment, behavioral health therapy, and substance use disorder services at parity with medical and surgical benefits. That means your plan cannot impose stricter limits on psychiatric visits than it does on primary care visits. As of 2026, the CMS mental health parity rules require plans to document and prove compliance.
6. Prescription Drugs
Every marketplace plan maintains a formulary, a list of covered drugs. Plans must cover at least one drug in every category and class listed in the United States Pharmacopeia. Generic drugs are almost always covered. Brand-name and specialty drugs may require prior authorization or step therapy.
7. Rehabilitative and Habilitative Services and Devices
Rehabilitative services help you recover lost function after illness or injury. Habilitative services help you develop or maintain function if you have a disability. Both are covered, including physical therapy, occupational therapy, speech therapy, and medically necessary devices. This distinction matters for children with developmental conditions.
8. Laboratory Services
Blood work, diagnostic imaging, biopsies, screenings, and other lab tests ordered by your provider. Preventive screenings with a grade A or B from the U.S. Preventive Services Task Force must be covered at no cost to you.
9. Preventive and Wellness Services
Annual wellness visits, recommended vaccinations, cancer screenings, cholesterol tests, blood pressure monitoring, and preventive counseling are covered with no cost-sharing on most ACA plans. The full list is published by healthcare.gov.
10. Pediatric Services
Children's dental and vision care are required benefits under the ACA. Adult dental and vision are not required, though many plans offer them as add-ons. Pediatric dental coverage must be available in every marketplace, either built into the health plan or purchasable as a stand-alone benefit.
What Health Insurance Typically Does NOT Cover in 2026
Essential benefits set the floor. They do not define the ceiling. Most standard plans exclude or limit the following services in 2026.
Common exclusions:
- Adult dental care (cleaning, fillings, crowns)
- Adult vision care (glasses, contacts, LASIK)
- Cosmetic procedures not medically necessary
- Fertility treatments (IVF, egg freezing)
- Long-term care and custodial care
- Experimental or investigational treatments
- Weight-loss surgery, in most cases unless BMI criteria are met
- Alternative therapies (acupuncture, chiropractic) unless your state mandates coverage
Coverage limits to watch:
- Mental health visits may have annual session caps on some legacy plans
- Specialty drug tiers can create high cost-sharing even when drugs are "covered"
- Out-of-network care typically requires higher cost-sharing or may not count toward your deductible
Reading your Summary of Benefits and Coverage before enrolling is the only way to know what a specific plan covers. Plans are required by law to provide this document in plain language.
2026 ACA Marketplace Income Limits: Who Qualifies for Subsidized Coverage
The 2026 marketplace uses 2025 Federal Poverty Level (FPL) figures, as published by ASPE at HHS. Your household income relative to the FPL determines whether you qualify for a premium tax credit, and at what level.
2026 Subsidy Cliff: The enhanced premium tax credits from 2021 through 2025 have expired. As of 2026, subsidies only extend to 400% of FPL. If your income is above that line, you pay the full unsubsidized premium.
2026 ACA Premium Tax Credit Income Range by Household Size
| Household Size | 100% FPL (Minimum) | 400% FPL (Maximum for Subsidy) |
|---|
| 1 | $15,650 | $62,600 |
| 2 | $21,150 | $84,600 |
| 3 | $26,650 | $106,600 |
| 4 | $32,150 | $128,600 |
| 5 | $37,650 | $150,600 |
| 6 | $43,150 | $172,600 |
| 7 | $48,650 | $194,600 |
| 8 | $54,150 | $216,600 |
| Each additional | +$5,500 | +$22,000 |
Table: 2026 ACA Marketplace Subsidy Income Range, 48 Contiguous States. Based on 2025 HHS poverty guidelines.
Note: If your state expanded Medicaid, the lower threshold is 138% FPL (approximately $21,597 for a single person). Below that, you likely qualify for Medicaid rather than marketplace subsidies. If your state did NOT expand Medicaid and your income falls below 100% FPL, you fall into the coverage gap and may have limited marketplace options.
Cost-Sharing Reductions (Silver Plans Only)
If you earn between 100% and 250% FPL and enroll in a Silver plan, you may also qualify for cost-sharing reductions that lower your deductibles, copays, and out-of-pocket maximum. These reductions are most valuable for households at or below 200% FPL.
How to Apply for ACA Marketplace Coverage in 2026
Open Enrollment Period: November 1, 2026 through January 15, 2027 for 2027 coverage. The 2026 plan year open enrollment ran from November 2025 through January 2026.
Special Enrollment Periods (SEPs): If you have a qualifying life event, you can enroll outside open enrollment. Qualifying events include losing job-based coverage, getting married or divorced, having a baby, moving to a new state, and gaining citizenship.
Application Steps
- Gather your documents (see checklist below).
- Go to HealthCare.gov or your state's marketplace portal to create an account.
- Complete the application with your household size, income estimate, and state of residence.
- Compare plans by metal tier (Bronze, Silver, Gold, Platinum) and review each plan's Summary of Benefits.
- Select a plan and pay your first premium to activate coverage.
- Confirm enrollment with your insurer and request an insurance card.
Documents You Will Need
- Social Security numbers for all household members applying for coverage
- Employer and income information for all household members (pay stubs, W-2s, or a wage estimate)
- Policy numbers for any current health insurance
- Immigration documents if applicable
- Birth dates for all household members
Common Reasons Applications Get Denied or Delayed
- Income listed does not match IRS records (resolve with a data-matching notice response)
- Citizenship or immigration status not verified
- Existing minimum essential coverage through an employer that meets affordability standards
- Missing documentation after a Special Enrollment Period request
- Applying outside of open enrollment without a qualifying life event
Plan Tiers and How They Affect What You Actually Pay
The 10 essential benefits are the same across all tiers. What changes is how costs are split between you and the insurer.
| Plan Tier | Average Insurer Share | Typical Deductible Range (2026) | Best For |
|---|
| Bronze | 60% | $6,000 to $9,000 | Healthy adults who rarely use care |
| Silver | 70% | $3,000 to $5,000 | Most people, especially with CSR eligibility |
| Gold | 80% | $500 to $1,500 | People with regular medical needs |
| Platinum | 90% | $0 to $500 | High medical users willing to pay higher premiums |
Table: 2026 ACA Plan Tiers, approximate cost-sharing ranges.
Silver plans are almost always the right starting point if your income qualifies for cost-sharing reductions, because the actual deductible can drop dramatically below the sticker figures above.
How State Medicaid Expansion Affects Your Options
In 2026, 40 states plus Washington D.C. have expanded Medicaid under the ACA. Expansion states offer Medicaid coverage to adults earning up to 138% of FPL regardless of household composition.
If you live in a non-expansion state, including Texas, Florida, Georgia, Alabama, Mississippi, Tennessee, Kansas, Wyoming, Wisconsin, and South Carolina, you may not qualify for Medicaid as a childless adult regardless of how low your income is.
Understanding which side of this line your state falls on determines whether you should be looking at Medicaid or marketplace coverage. The CoveredUSA screener accounts for both pathways when you enter your state and income.
Frequently Asked Questions
Does health insurance cover mental health treatment in 2026?
Yes. The ACA requires mental health and substance use disorder services to be covered in every compliant plan as one of the 10 essential benefits. Federal parity rules require insurers to cover mental health treatment at the same level as physical health care. Outpatient therapy, inpatient psychiatric care, and substance use disorder treatment are all included.
Does health insurance cover prescription drugs?
Every ACA marketplace plan must cover prescription drugs. Coverage is based on a formulary, and your cost depends on which tier the drug falls into. Generic drugs carry the lowest cost-sharing. Specialty drugs at higher tiers can still require significant out-of-pocket spending even with insurance.
Is dental covered by health insurance?
Pediatric dental coverage is required for children. Adult dental care is not a required essential benefit under the ACA. Most marketplace health plans do not include adult dental. You can purchase stand-alone dental coverage through the marketplace or separately.
Does health insurance cover pregnancy and childbirth?
Yes. Maternity and newborn care is one of the 10 essential health benefits. Prenatal visits, labor and delivery, and postnatal care are all covered. This applies to all ACA-compliant individual and small-group plans in 2026.
What is the income limit to get help paying for health insurance in 2026?
For 2026, premium tax credits are available to individuals earning between 100% and 400% of the federal poverty level, which is approximately $15,650 to $62,600 for a single person. For a family of four, the range is $32,150 to $128,600. If your income is above 400% FPL, you pay the full unsubsidized premium. If it is below 100% FPL, you may qualify for Medicaid.
What does health insurance NOT cover?
Most plans exclude adult dental and vision, cosmetic procedures, fertility treatments, long-term custodial care, and experimental treatments. Coverage for weight-loss surgery, chiropractic care, and alternative therapies varies by plan and state. Always check your plan's Summary of Benefits and Coverage before enrolling.
Can I get health insurance if I missed open enrollment?
You can enroll outside of open enrollment if you have a qualifying life event, called a Special Enrollment Period. Qualifying events include losing job-based coverage, marriage, divorce, birth of a child, moving to a new state, and gaining or losing Medicaid eligibility. Some states have year-round enrollment for people below certain income thresholds.
