Health Insurance in 2026: How to Review Your Coverage, Compare Costs, and Avoid Surprises

Bottom line: Even if you like your current health plan, it’s worth reviewing your options each year. Premiums, provider networks, drug coverage, and eligibility rules can change — and those changes can affect your access to care and your out-of-pocket costs.

Health insurance in the United States remains a patchwork of employer plans, Marketplace coverage under the Affordable Care Act (ACA), Medicaid, Medicare, and other public programs. For families, caregivers, and individuals managing chronic conditions, small plan changes can have big real-world effects.

Here’s what to review in 2026, based on guidance from the Centers for Medicare & Medicaid Services (CMS), HealthCare.gov, and independent health policy research organizations such as KFF.

1. Check More Than the Monthly Premium

Many people focus on the monthly premium — the amount you pay each month to keep coverage. But total costs also include:

Deductible: What you must pay before most services are covered.
Copayments and coinsurance: Your share of costs after the deductible.
Out-of-pocket maximum: The most you would pay in a year for covered services.

CMS requires plans sold on the ACA Marketplace to clearly list these amounts, but they can shift from year to year. A slightly lower premium may come with a higher deductible — or narrower provider network.

Why this matters: For people with ongoing medical needs, such as diabetes, asthma, heart disease, or mental health conditions, the out-of-pocket maximum can be just as important as the premium.

2. Confirm Your Doctors and Hospitals Are Still In-Network

Insurance plans regularly update their provider networks. A hospital or specialist that was covered last year may not be in-network this year.

According to CMS consumer guidance, using in-network providers typically costs far less than going out of network. Before your plan renews:

Check your insurer’s updated provider directory.
Call your doctor’s office to confirm they still accept your plan.
If you have a planned procedure, confirm coverage in writing when possible.

This step is especially important for people receiving cancer care, pregnancy care, behavioral health treatment, or specialty services.

3. Review Prescription Drug Coverage Carefully

Each plan maintains a drug formulary — a list of covered medications. Insurers can change:

Which drugs are covered
Which “tier” a medication is placed in (affecting cost)
Prior authorization requirements

If you take regular medications, compare formularies directly before renewing coverage. Even a tier shift can increase monthly pharmacy costs.

For older adults and people with disabilities enrolled in Medicare, Medicare.gov provides plan comparison tools for Part D and Medicare Advantage prescription drug plans.

4. Understand Changes in Medicaid and Marketplace Eligibility

Eligibility for Medicaid and ACA Marketplace subsidies is based on income and household size. Changes in employment, marriage, divorce, or family size can affect eligibility.

HealthCare.gov advises consumers to update their income information promptly if it changes during the year. This can prevent unexpected tax bills tied to advance premium tax credits.

For families: Children may qualify for Medicaid or the Children’s Health Insurance Program (CHIP) even if parents do not. Coverage options can differ within the same household.

5. Compare Plans Even If You’re Automatically Re-Enrolled

Many Marketplace enrollees are automatically renewed into their current plan if they take no action. But plan details — including premiums and cost-sharing — may change.

KFF health policy analyses consistently show that consumers who actively compare plans during open enrollment sometimes find lower-cost options with similar benefits.

If you receive employer-sponsored insurance, your company’s annual benefits enrollment period is also an opportunity to review:

Health savings account (HSA) eligibility
Flexible spending account (FSA) limits
Dental and vision add-ons
Mental health and telehealth benefits

6. Don’t Overlook Preventive Care Coverage

Under federal law, many preventive services must be covered without cost-sharing when delivered by in-network providers. These include recommended vaccines, certain cancer screenings, blood pressure checks, and some preventive dental services for children.

Preventive coverage recommendations are based in part on guidance from the U.S. Preventive Services Task Force (USPSTF).

Why this matters: Using preventive benefits can help detect conditions earlier — often reducing long-term health and financial risk.

7. Watch for Mental Health and Substance Use Coverage Parity

Federal mental health parity rules require most health plans to provide mental health and substance use disorder benefits comparable to medical and surgical benefits. However, differences can appear in network size or prior authorization practices.

If you or a family member relies on therapy, psychiatric care, or medication-assisted treatment, review coverage details carefully before renewing.

8. Understand Dental and Oral-Systemic Health Connections

Adult dental coverage is not automatically included in most standard Marketplace health plans. However, oral health is closely connected to overall health. Untreated gum disease has been associated with conditions such as diabetes and cardiovascular disease.

If dental coverage is not bundled with your health plan, compare standalone dental options — especially if you have chronic health conditions.

When to Seek Help

If you are confused about your options:

Use the official HealthCare.gov enrollment assistance tools.
Seek help from certified navigators or licensed insurance brokers.
For Medicare questions, contact your State Health Insurance Assistance Program (SHIP).

Avoid relying solely on unsolicited phone calls or advertisements. Official government websites (ending in .gov) provide reliable enrollment information.

What This Means for Readers

Health insurance is not “set it and forget it.” Even small plan changes can affect:

Access to doctors and specialists
Medication affordability
Financial protection during serious illness
Preventive care access

Taking 30–60 minutes to review your coverage each year can reduce surprise bills and ensure you and your family have access to needed care.

In a healthcare system where costs remain high and policies evolve, staying informed is one of the most practical steps you can take to protect both your health and your finances.
