Individual Health Insurance: What to Check Before You Choose

Choosing a health insurance plan for yourself can feel like a high‑stakes puzzle. It is often the most expensive decision you make each year, and getting it wrong could mean being stuck with a plan that doesn’t cover your doctors, your medications, or your expected medical needs.

The good news is that while health insurance is complex, you only need to check a small handful of things to pick the right plan. This guide walks you through those essential factors—from premiums and out‑of‑pocket costs to provider networks and prescription drug coverage.

Disclaimer: This content is for informational purposes only. Health insurance plans and regulations differ significantly between the USA, UK, and Canada. The detailed cost and network advice below focuses on the US individual market. Always review your plan’s official documents and consult a licensed insurance professional or healthcare navigator before enrolling.

Key Takeaways at a glance:
Before you select a plan, verify four things: (1) the total estimated yearly cost (premiums + deductibles + copays), not just the monthly premium; (2) whether your preferred doctors and hospitals are in‑network; (3) that your regular prescriptions are on the plan’s formulary; and (4) how the plan handles out‑of‑network emergency care. Start by estimating your healthcare needs for the coming year—first dollar to last.

Why This Decision Matters More Than Ever

If you are shopping in the U.S. individual market, 2026 is an expensive year to get it wrong. The enhanced premium tax credits that lowered costs for many ACA marketplace enrollees expired on January 1, 2026. As a result, the average monthly premium for a benchmark silver plan climbed to $625, while the lowest‑cost bronze plan averages $456 per month. For the average subsidized household, the annual out‑of‑pocket premium more than doubled from $888 in 2025 to $1,904 in 2026. The share of enrollees receiving any subsidy dropped from 92% in 2024–2025 to 87% for 2026.

For those not receiving subsidies, the stakes are even higher. That is why carefully comparing plan details—not just the headline monthly number—is critical.

The open enrollment period for 2026 coverage ran from November 1, 2025, through January 15, 2026, in most states. While that window has closed for 2026, the next enrollment period for 2027 coverage will begin in November 2026. Use the time between now and then to understand what to look for so you are ready.

Step 1: Understand the True Cost of a Plan

The biggest mistake people make is looking only at the monthly premium (the amount you pay each month just to have insurance). But the premium is only the beginning. A low‑premium plan often comes with a very high deductible and high copays for services, meaning you will pay a lot more when you actually need care.

Key Cost Terms to Know

• Premium – The monthly amount you pay to keep the policy active.

• Deductible – The amount you must pay out‑of‑pocket for covered services before the insurance starts paying its share. For 2026, the maximum annual out‑of‑pocket limit for self‑only coverage under the ACA is $10,600.

• Copayment (Copay) – A fixed dollar amount you pay for a specific service, such as $40 for a primary care visit or $15 for a generic drug.

• Coinsurance – A percentage of the cost you pay after meeting your deductible, for example, 20% of the cost of a hospital stay.

• Out‑of‑pocket maximum – The most you will have to pay in a year (including deductibles, copays, and coinsurance) before the insurance covers 100% of allowed costs.

Common mistake: Choosing a silver or bronze plan solely because the monthly premium looks affordable. Many people end up with a high‑deductible health plan (HDHP) without realizing that they will have to pay thousands of dollars before most coverage kicks in. For 2026, all individual market bronze and catastrophic plans are considered HDHPs. A bronze plan’s deductible can be as high as the out‑of‑pocket maximum—over $10,000.

How to Estimate Your True Yearly Cost

1. Estimate your expected healthcare use for the coming year. Do you anticipate any surgeries, childbirth, or planned hospitalizations? Do you have chronic conditions that require regular specialist visits or expensive medications?

2. Add up: (Monthly premium × 12) + (deductible) + (expected copays and coinsurance).

3. Compare that total across three or four plan options.

If you rarely need care beyond preventive visits and generic drugs, a low‑premium, high‑deductible plan might be cost‑effective. But if you expect to need significant care, a plan with a higher premium and lower deductible may save you money overall.

Step 2: Check the Provider Network

Your plan’s network is the list of doctors, hospitals, and other providers who have agreed to provide services at negotiated rates. If you go outside the network, you will pay significantly more—sometimes the entire bill.

Types of Networks

The four primary network types in the U.S. individual market are HMO, PPO, EPO, and POS. Their key differences are how they handle in‑network versus out‑of‑network care and whether referrals are required.

Plan Type	In‑Network Only?	Primary Care Referral Required?	Out‑of‑Network Coverage
HMO (Health Maintenance Organization)	Yes	Yes	None
EPO (Exclusive Provider Organization)	Yes	No	None
PPO (Preferred Provider Organization)	No	No	Yes (but at higher cost)
POS (Point of Service)	Yes	Yes	Yes (but at higher cost)

HMOs typically offer the lowest monthly premiums but require you to select a primary care physician (PCP) and obtain referrals to see specialists. If you want flexibility to see out‑of‑network providers, a PPO is a better choice, but you will pay higher premiums and additional costs when using out‑of‑network care.

Before You Enroll

• Call your current doctors and ask if they accept the plan you are considering. Do not rely solely on online directories, which can be outdated.

• If you have a complex medical condition, verify that the specialists, hospitals, and treatment facilities you rely on are in‑network.

• Ask about emergency care. Under the ACA, plans must cover emergency services at in‑network cost‑sharing levels even at out‑of‑network hospitals. However, some plans may still impose additional charges for out‑of‑network emergency care. Call the insurance company to ask: “If I go to an out‑of‑network emergency room, what will I owe?”

Step 3: Review Prescription Drug Coverage (The Formulary)

If you take any regular medications—even just a generic drug—you must check the plan’s formulary (the list of drugs the plan covers). A plan that does not cover your medication could cost you thousands of dollars extra in a year.

How to Check Your Drug Coverage

Step 1: Obtain the plan’s formulary document. You can usually find it on the insurer’s website or by calling member services.
Step 2: Look for each of your medications by name and dosage.
Step 3: Note the tier of each drug. Most formularies use a four‑ or five‑tier system:

Tier	Description	Out‑of‑pocket cost
1	Preferred generic	Lowest copay
2	Preferred brand	Moderate copay
3	Non‑preferred brand	Higher copay
4	Specialty drugs	Highest cost‑sharing (often coinsurance)

Step 4: Check for prior authorization requirements. Some drugs require your doctor to obtain approval from the insurance company before the plan will cover them. Step therapy (trying a cheaper drug first) may also be required.

What if your drug is not on the formulary? You or your doctor can request a formulary exception. If the exception is granted, the plan will usually cover the drug, but you may be charged the highest tier cost‑sharing amount. The process can take weeks, so if you rely on a medication, choose a plan that already covers it.

Step 4: Identify What Is Covered (And What Is Not)

All ACA‑compliant individual plans must cover essential health benefits, including:

• Ambulatory patient services (outpatient care)

• Emergency services

• Hospitalization

• Laboratory services

• Maternity and newborn care

• Mental health and substance use disorder services

• Prescription drugs

• Rehabilitative and habilitative services

• Preventive and wellness services

• Pediatric services (including oral and vision care)

However, many plans exclude or limit:

• Adult dental and vision coverage – Often sold as separate policies.

• Non‑formulary drugs – As discussed above.

• Out‑of‑network non‑emergency care – May not be covered at all.

• Cosmetic procedures – Almost never covered.

Hidden risk: Some low‑premium plans have “narrow networks” that exclude major hospitals in your area. If you live in a rural area, a narrow network may leave you with no in‑network hospital within a reasonable distance. Always check the provider directory before enrolling.

What About the UK and Canada?

While this guide focuses primarily on the U.S. individual market (because the UK and Canada have government‑funded systems that cover most essential care), readers in those countries may still purchase supplementary private insurance.

United Kingdom – Private Health Insurance

In the UK, the National Health Service (NHS) covers most medical care. Private health insurance is supplementary – it allows you to access private hospitals, specialists, and treatments that can bypass NHS waiting lists.

Private insurance typically covers:

• Private GP appointments

• Physiotherapy

• Mental health services

• Diagnostic tests (MRI, CT scans)

• Elective surgeries in private hospitals

What it usually does not cover: GP appointments (though some plans include private GPs), A&E (emergency) services, chronic condition management, or pre‑existing conditions (depending on the policy).

Costs range from £50 to £300 per month, depending on age, health, and coverage level. Before buying, verify which hospitals are on the insurer’s “approved list” – most UK private plans cover treatment only at hospitals on that list.

Canada – Private Health Insurance

Canada’s provincial health plans cover medically necessary hospital and physician services. Private insurance typically covers what the public plan does not: prescription drugs, dental care, vision care, physiotherapy, psychotherapy, and ambulance services.

Most Canadians obtain private coverage through employer plans. If you are buying an individual plan, be aware that insurers will ask detailed health questions and may exclude pre‑existing conditions or charge higher premiums. The best plan for you may be one that coordinates with your spouse’s or employer’s coverage to avoid duplicate benefits.

Step 5: What to Do Before Open Enrollment 2027

Use the months before the next open enrollment period to prepare. You will not have time to research everything during the enrollment frenzy.

A 12‑Month Preparation Plan

If you are already insured: Review your current plan’s 2026 Summary of Benefits and Coverage (SBC) to understand exactly what it covered and what it did not. Note any denied claims or surprise bills from the past year.

If you are uninsured: Start keeping a log of your healthcare use for the next few months—doctor visits, prescriptions, lab work. That log will help you estimate your needs.

Check with your employer: If you are eligible for employer‑sponsored coverage, compare the employer plan to individual marketplace plans BEFORE you assume the employer plan is superior. Sometimes individual plans with subsidies can be more affordable.

Verify with your doctors and pharmacy: Collect a list of all providers you see (primary care, specialists, therapists, dentists), plus a list of all your prescriptions with dosages. You will need this to check networks and formularies.

If you have a chronic condition: Contact patient advocacy organizations. Many have staff who can help you navigate plan selection for your specific condition.

One Week Before Enrollment

• Write down your maximum budget for total annual health costs (premiums + out‑of‑pocket).

• Decide your network preference. Are you willing to switch doctors to save on premiums? Or do you need to keep your current providers?

• Create a shortlist of 4–5 plans using the marketplace’s comparison tool.

• Call each plan’s member services with your shortlist of questions:

  • “Is my primary care doctor (Dr. X) in your network?”

  • “Are my prescriptions (list them) on your formulary? What tier are they?”

  • “What is the average wait time for a new patient appointment for a primary care doctor in my area?”

  • “Do you require prior authorization for [your specific medication]?”

• Use a “total cost calculator.” Many marketplace websites and independent insurance brokers have free calculators that estimate your total annual cost for each plan based on your expected usage.

Uncommon tip: Look at the plan’s deductible for prescription drugs separately from the medical deductible. Some plans have separate deductibles for drugs, meaning you could pay full price for medications even after meeting your medical deductible.

Checklist: 10 Questions to Answer Before You Enroll

1. What is the total annual cost (premiums + expected out‑of‑pocket) for each plan I am considering?

2. Are my preferred doctors and hospital in the plan’s provider network?

3. Is each of my regular prescription drugs on the plan’s formulary, and at what tier?

4. Are there any prior authorization or step therapy requirements that could delay access to my medications?

5. What is the maximum out‑of‑pocket amount I could have to pay in a single year?

6. Does the plan cover the specific services I am likely to need (e.g., mental health, physical therapy)?

7. For UK/CA readers: What does the public system cover, and what am I buying private insurance to supplement?

8. For self‑employed/independent workers: Am I eligible for a premium tax credit, and how does that affect my net monthly cost?

9. What is the plan’s policy on emergency room visits at out‑of‑network hospitals?

10. What is the customer service reputation of the plan’s parent company? Read recent reviews about claims processing and prior authorization delays.

Frequently Asked Questions

1. What is the difference between a premium and a deductible?

Your premium is the fixed monthly cost you pay just to have the insurance policy. Your deductible is the amount you must pay for covered medical services before the insurance company starts paying its share. Think of the premium as the entry fee and the deductible as the initial spending you cover yourself each year.

2. I am healthy and rarely see a doctor. Should I buy the cheapest plan?

Possibly, but with caution. The cheapest plan is usually a bronze or catastrophic plan, which has a very high deductible—often $10,000 or more for an individual. This means that if you have an unexpected accident or sudden illness, you could be responsible for that large amount before coverage kicks in. Many people find a middle‑ground silver plan is better: premiums are not the lowest, but out‑of‑pocket costs are more manageable when unexpected events occur.

3. How do I find out if a health plan covers the prescription drugs I take?

Request the plan’s formulary (sometimes called the “drug list” or “preferred drug list”) before enrolling. Search for each of your medications by name and dosage. If a drug is not listed, you can still request a formulary exception, but the process can take weeks. It is safer to choose a plan that already covers your essential medications.

4. What should I do if my doctors are not in a plan’s network?

You have three options: (1) keep your doctors and choose a different plan that includes them in‑network; (2) switch to in‑network providers if you are willing to change doctors; or (3) if a PPO plan is available and you can afford the cost, use out‑of‑network benefits (paying higher copays and coinsurance). Do not assume you can get a “network gap exception” – those are rarely granted.

5. What documents should I keep after I enroll?

Once you enroll, request and save your Evidence of Coverage (EOC) or Certificate of Insurance (COI), the Summary of Benefits and Coverage (SBC), the formulary, and the provider directory. You will need these if there is a dispute about what is covered or what you owe.

When to Talk to a Professional

If you have a complex medical history, a chronic condition requiring expensive medications, or a family member with significant healthcare needs, you may benefit from speaking with a licensed health insurance navigator or an independent insurance broker.

Navigators are free to consumers and are trained to help you compare ACA marketplace plans. Independent brokers can show you plans from multiple insurers, including plans sold outside the marketplace.

Smart questions to ask a broker or navigator:

• “Based on my expected healthcare use, which metal level (bronze, silver, gold) is most cost‑efficient for me?”

• “Which plans in my area have the broadest provider networks?”

• “How many plan members typically receive a denied prior authorization for [your specific condition] last year?”

• “Are there any cost‑sharing reduction subsidies available to me if I choose a silver plan?”

The Bottom Line – Honest and Human

Choosing an individual health insurance plan is one of the most consequential financial and health decisions you will make. You do not need to become a policy expert, but you do need to check four things: the total yearly cost, the provider network, the prescription drug formulary, and the out‑of‑pocket maximum.

Start now—not in November. Make your doctor and pharmacy lists. Estimate your expected care. Then, when open enrollment arrives, you will be ready to compare apples to apples, not just monthly premiums.

Good health insurance does not have to be perfect. It just has to be the right fit for you.
