Step 1: Learn the Basics
What Is Health Insurance?
Health insurance helps pay for the cost of medical care. Instead of paying the full cost of covered healthcare services yourself, you and your health insurance company share the cost based on the terms of your health plan.
Health insurance can help cover services such as:
-
Doctor visits
-
Hospital stays
-
Emergency care
-
Preventive care
-
Prescription medications
-
Laboratory tests
-
Medical procedures
Every health insurance plan is different, so it's important to understand what your specific plan covers and what costs you may be responsible for.
Why Is Health Insurance Important?
Healthcare can be expensive. Health insurance helps protect you from paying the full cost of covered medical services and can make it easier to access the care you need.
Having health insurance may also provide access to:
-
Preventive care, such as annual checkups and screenings
-
Lower costs when using in-network providers
-
Prescription drug coverage
-
Financial protection during unexpected illnesses or injuries
Understanding how your insurance works can help you avoid unexpected costs and make informed healthcare decisions.
How Does Health Insurance Work?
Health insurance is a cost-sharing agreement between you and your insurance company.
You typically pay a monthly premium to keep your coverage active. When you receive healthcare services, the amount you pay depends on your health plan and the type of service you receive.
For many covered services, you may be responsible for costs such as:
-
A copay
-
A deductible
-
Coinsurance
Once you've reached your plan's out-of-pocket maximum for covered, in-network services, your health plan generally pays 100% of covered costs for the remainder of the plan year.
What is a Premium?
A premium is the amount you pay to keep your health insurance coverage active.
Most people pay their premium every month, whether or not they use healthcare services.
Example:
You pay $250 per month for your health insurance. This monthly payment keeps your coverage in effect.
What is a Deductible?
A deductible is the amount you pay each plan year for certain covered healthcare services before your health insurance begins sharing the cost.
Think of your deductible as your portion of the cost before your insurance starts contributing toward many covered services. As you pay for eligible medical expenses, those payments count toward meeting your deductible. Once you've met it, your insurance generally begins sharing the cost of covered services according to your plan (for example, through coinsurance or copays).
It's important to remember that not every healthcare service is subject to the deductible. Many health plans cover certain preventive services—such as annual wellness exams, routine vaccinations, and recommended health screenings—without requiring you to meet your deductible first. Your specific benefits depend on your health plan.
Example
Let's say your health plan has a $2,000 deductible.
You haven't received any medical care yet this year.
You need an outpatient procedure that costs $2,500, and the amount is applied to your deductible.
-
You pay the first $2,000 because you haven't met your deductible yet.
-
You've now met your deductible for the year.
-
The remaining $500 is generally shared between you and your insurance according to your plan's cost-sharing rules. For example, if your plan has 20% coinsurance, you would pay 20% of that remaining $500 ($100) and your insurance would pay the other 80% ($400).
Important: The actual amount you pay depends on your health plan's deductible, coinsurance, copays, and whether you receive care from an in-network provider.
What is a Copay?
A copay, or copayment, is a set amount you may pay for certain covered healthcare services or prescriptions. For example, your health plan might require a $25 copay for a primary care visit or a $10 copay for a prescription medication.
Copays can vary depending on the type of care you receive. A specialist visit, urgent care visit, emergency room visit, or prescription may each have a different copay.
Good to Know: A copay is different from your deductible and coinsurance. Depending on your health plan, some services may require a copay even if you haven't met your deductible yet. Always review your plan details to understand when copays apply.
What is Coinsurance?
Coinsurance is the percentage of covered healthcare costs you pay after you've met your deductible.
Your insurance company pays the remaining covered amount according to your plan.
Example:
Your plan has 20% coinsurance.
A covered procedure costs $1,000 after you've met your deductible.
-
You pay $200
-
Your insurance pays $800
Out-of-Pocket Maximum
The out-of-pocket maximum is the most you'll pay during your plan year for covered, in-network healthcare expenses.
After you reach this limit, your insurance plan generally pays 100% of covered, in-network services for the rest of the plan year.
Keep in mind that monthly premiums and certain services may not count toward your out-of-pocket maximum. Check your specific health plan for details.
Health Insurance at a Glance
Think of health insurance like a team effort.
-
You pay a premium each month to keep your coverage active.
-
If you need medical care, you may first pay toward your deductible.
-
Depending on your plan, you may also pay a copay or coinsurance for covered services.
-
Once you reach your out-of-pocket maximum, your insurance generally pays 100% of covered, in-network costs for the rest of the plan year.
Understanding these five terms is the first step toward making informed healthcare decisions.
Frequently Asked Questions
Do I have to use my health insurance every year?
No. Even if you don't need medical care, maintaining health insurance can help protect you from unexpected healthcare costs if you become sick or injured.
Does every health insurance plan work the same way?
No. Every health plan has its own rules, costs, provider network, and covered services. Always review your plan documents to understand your specific benefits.
Why do I still receive a bill if I have health insurance?
Health insurance does not always pay the full cost of covered healthcare services. Depending on your plan, you may still be responsible for a deductible, copay, coinsurance, or services that are not covered.
Where can I find information about my coverage?
You can review your plan documents, log in to your insurance company's member portal, or call the customer service number listed on the back of your insurance card.
STEP 2: Know Your Plan
Goal
Learn how to understand your health insurance plan so you can make informed healthcare decisions and avoid unexpected costs.
What You'll Learn
✔ Identify the different types of health insurance plans.
✔ Understand how provider networks and referrals work.
✔ Read and understand your insurance card.
✔ Check whether your doctors, hospitals, and prescriptions are covered.
Why This Matters
Choosing the right doctor, visiting the correct facility, or understanding your benefits before receiving care can help you avoid unexpected costs and delays. Learning how your health plan works will help you make informed decisions and get the most from your health insurance.
Understanding Your Insurance Card
Your health insurance card is one of the most important tools you'll use when accessing healthcare. While every insurance company designs its cards differently, most include similar information to help identify your coverage and process your healthcare claims.
You should carry your insurance card with you and present it whenever you receive medical care or fill a prescription.
Information You'll Commonly Find on Your Insurance Card
Although every insurance card looks a little different, most include the same key pieces of information. Understanding what each item means can help you use your health insurance with confidence.
Member ID
Your Member ID is your unique identification number. It tells your healthcare provider and insurance company who you are and links you to your health insurance plan.
Your provider will use this number when submitting claims for payment.
Group Number
If your insurance is provided through an employer or organization, your card may include a Group Number.
This number identifies the employer or organization sponsoring your health plan.
Some health plans, such as individual Marketplace plans, may not include a group number.
Health Plan Name
Your insurance card usually lists the name of your health plan.
Knowing your plan name can help you:
-
Verify your benefits
-
Find in-network providers
-
Access your member portal
-
Contact customer service
Primary Care Provider (PCP)
Some insurance cards include the name of your assigned Primary Care Provider (PCP).
If your plan requires a PCP, this is generally the healthcare provider who coordinates your routine medical care and, when required by your plan, provides referrals to specialists.
Not every insurance plan requires you to select a PCP, so this information may not appear on every card.
Copays
Some insurance cards list the copay amounts for common services, such as:
-
Primary care visits
-
Specialist visits
-
Emergency room visits
-
Urgent care visits
If your card does not list these amounts, you can usually find them in your plan documents or by contacting your insurance company.
Customer Service
Most insurance cards include a customer service phone number.
Call this number if you have questions about:
-
Your benefits
-
Covered services
-
Claims
-
Prior authorizations
-
Finding in-network providers
-
Prescription drug coverage
Keeping this number handy can save time when you need answers about your health plan.
Pharmacy Information
If your health plan includes prescription drug coverage, your insurance card may include pharmacy information used to process your prescriptions.
Present your insurance card when filling prescriptions so your pharmacy can verify your coverage and determine your cost.
Website or Member Portal
Many insurance cards include a website where you can:
-
View your benefits
-
Find in-network providers
-
Check claims
-
Download a digital insurance card
-
Review your Explanation of Benefits (EOB)
-
Access health and wellness resources
Creating an online member account can make it easier to manage your health insurance and find information when you need it.
Good to Kn0w
Your insurance card is a helpful starting point, but it doesn't contain all the details about your coverage. For more information about your benefits, costs, provider network, or covered services, review your plan documents or visit your insurance company's member portal.
Tips for Using Your Insurance Card
✔ Carry your insurance card with you at all times.
✔ Present your insurance card at every medical appointment and when filling prescriptions.
✔ Notify your healthcare provider if your insurance changes.
✔ Review your insurance card each year to make sure your information is current.
✔ Contact your insurance company if your card is lost, damaged, or contains incorrect information.
Quick Tip
Your insurance card is your key to accessing your health benefits—but it doesn't explain everything your plan covers. For complete details about your coverage, costs, and benefits, review your plan documents or log in to your insurance company's member portal.
Types of Health Insurance Plans
Not every health insurance plan works the same way.
Understanding your plan type helps you know:
-
Which doctors you can see.
-
Whether you need referrals.
-
How much flexibility you have.
-
What your costs may be.
HMO (Health Maintenance Organization)
An HMO usually requires you to:
✔ Choose a Primary Care Provider (PCP)
✔ Receive referrals before seeing many specialists
✔ Use in-network providers except in emergencies
Best For
People who want lower costs and don't mind coordinating care through one primary doctor.
PPO (Preferred Provider Organization)
A PPO generally offers more flexibility.
You can often:
✔ See specialists without a referral
✔ Visit both in-network and out-of-network providers (usually at a higher cost)
Best For
People who value provider choice and flexibility.
EPO (Exclusive Provider Organization)
An EPO combines features of HMOs and PPOs.
Typically:
✔ No referral required
✔ Must stay in-network for most covered services
POS (Point of Service Plan)
A POS plan combines elements of both HMOs and PPOs.
Typically:
✔ Primary Care Provider required
✔ Referrals often required
✔ Some out-of-network coverage available
Comparing Plans
Each type of health insurance plan has its own rules, costs, and level of flexibility. Comparing plan types can help you better understand how your coverage works and what to expect when seeking care.
STEP 3: Understand Your Healthcare Costs
How Does the Healthcare Billing Process Work?
Receiving medical care starts a billing process between your healthcare provider and your insurance company. Understanding what happens behind the scenes can make it much easier to understand the paperwork and bills that arrive later.
For most insured healthcare services, the process looks something like this:
You Receive Care → Provider Submits a Claim → Insurance Processes the Claim → You Receive an EOB → Provider Sends a Bill
Let's break down what each of these steps means.
Each step plays a different role in determining how your healthcare services are paid for and what portion of the cost may be your responsibility. Understanding how these pieces work together can make it easier to review your insurance information, recognize potential errors, and know what to expect before paying a medical bill.
1. You Receive Healthcare
You visit a doctor, hospital, laboratory, imaging center, or another healthcare provider.
Depending on your plan, you may pay a copay or another amount at the time of your visit.
4. You Receive an Explanation of Benefits
After processing the claim, your insurance company usually provides an Explanation of Benefits (EOB).
The EOB explains how the claim was processed and what you may owe.
Remember: An EOB is not a bill.
2. Your Provider Submits a Claim
After providing care, your healthcare provider generally sends a claim to your insurance company.
A claim is essentially a request for payment. It tells your insurer what services you received and how much the provider charged.
5. Your Provider Sends a Medical Bill
If you have a remaining financial responsibility, your healthcare provider may send you a medical bill requesting payment.
Before paying, compare the bill with your EOB and make sure your insurance has processed the claim correctly.
3. Your Insurance Processes the Claim
Your insurance company reviews the claim according to your health plan.
It may consider things such as:
-
Whether the service is covered
-
Whether the provider is in-network
-
The plan's allowed amount
-
Your deductible
-
Your copay or coinsurance
-
Whether prior authorization was required
Your insurer then determines what it will pay and what portion may be your responsibility.
6. Have Questions? Contact Your Insurance Company
If something on your EOB or medical bill doesn't make sense, don't be afraid to ask questions. Contact the customer service number on your insurance card and ask your insurance company to explain how the claim was processed and why a certain amount is listed as your responsibility.
Before calling, have your insurance card, EOB, medical bill, and date of service nearby. Take notes during the conversation, including the representative's name, the date of the call, and any next steps you are given.
Remember: Understanding what you're being charged for is an important part of becoming your own healthcare advocate.
Claim vs. EOB vs. Medical Bill
These three terms are easy to confuse, but they represent different parts of the billing process.
Claim
A claim is information submitted to your insurance company requesting payment for healthcare services you received.
Think:
Provider → Insurance Company
Explanation of Benefits (EOB)
An Explanation of Benefits is a statement from your insurance company explaining how it processed the claim.
It may show:
-
Amount the provider charged
-
Allowed amount
-
Insurance discounts or adjustments
-
Amount insurance paid
-
Amount applied to your deductible
-
Copay or coinsurance
-
Amount you may owe
Think:
Insurance Company → You
Medical Bill
A medical bill comes from the healthcare provider and requests payment for the amount the provider says you owe.
Think:
Healthcare Provider → You
An Easy Way to Remember
Claim = Request for payment
EOB = Explanation
Medical Bill = Request for you to pay
Understanding Common Billing Terms
Knowing a few key terms can make your EOB and medical bills much easier to understand.
Amount Charged
The amount charged is the price the healthcare provider initially bills for a service.
This isn't necessarily the amount you will pay.
Why Did I Receive More Than One Bill?
Receiving multiple bills after one appointment or hospital visit can be confusing, but it doesn't necessarily mean you've been charged more than once for the same thing.
One visit can involve several separate healthcare providers.
For example, imagine you have surgery at a hospital.
You might receive separate bills from:
The hospital
— for use of the facility, supplies, equipment, and other services.
The surgeon
— for performing the procedure.
The anesthesiologist
— for providing anesthesia.
The laboratory
— for testing samples.
The radiologist
— for interpreting imaging.
Each provider may submit its own claim and send its own bill.
Good to Know
Don't assume that multiple bills are automatically duplicates. Compare the provider name, date of service, and services listed on each bill and EOB.
If something appears twice or you don't recognize a charge, contact the provider's billing department or your insurance company for clarification.
So, How Do I Know What I Actually Owe?
Now that you understand how the billing process works, it's time to put the pieces together. Comparing your EOB with your medical bill can help you understand how your costs were calculated and determine what you may be responsible for paying.
When you receive a medical bill:
Step 1: Check That Insurance Processed the Claim
Look for the corresponding claim in your insurance member portal or EOB.
What About Balance Billing?
Balance billing can occur when a provider bills you for an amount beyond what your insurance plan recognizes or pays for a service in circumstances where the provider is permitted to seek that difference from you.
This can be especially important with out-of-network providers.
However, federal and state laws provide protections against certain types of balance and surprise billing.
Good to Know
The amount a healthcare provider charges is not necessarily the amount you owe.
Your insurance coverage, network status, deductible, copays, coinsurance, negotiated rates, and other plan rules can all affect your final responsibility.
Learning to compare your claim, EOB, and medical bill can help you better understand your healthcare costs and identify charges that may need further review.
STEP 4: When Things Don't Go As Planned
When Insurance Doesn't Go as Expected
You and your healthcare provider may agree on a treatment, test, medication, or procedure, but that doesn't always mean your health insurance will immediately approve or pay for it.
Your plan may require additional information, a prior authorization, or proof that a service meets its requirements for medical necessity. In other situations, a claim may be denied after you've already received care.
A delay or denial doesn't always mean the process is over. Understanding why your insurance made its decision is the first step toward figuring out what you can do next.
What Is Prior Authorization?
Prior authorization—sometimes called preauthorization or preapproval—is a process some health plans use to review certain healthcare services or medications before they are provided.
Your insurance company may require prior authorization for things such as:
-
Certain prescription medications
-
MRIs, CT scans, and other imaging
-
Surgeries and procedures
-
Medical equipment
-
Specialty treatments
-
Certain therapies
The exact requirements depend on your health plan.
How Does Prior Authorization Work?
The process will vary, but it commonly looks something like this:
1. Your provider recommends care.
Your healthcare provider determines that you need a particular treatment, medication, test, or procedure.
Important to Know
Prior authorization is not the same as a guarantee of payment.
Even when a service receives prior authorization, your final coverage can depend on other plan requirements, including eligibility, benefits, network status, and the circumstances when the service is provided.
What Does "Medical Necessity" Mean?
You may see the words medically necessary or medical necessity in your insurance documents.
Health plans generally use medical-necessity criteria to determine whether a healthcare service meets the plan's requirements for coverage based on factors such as your condition, clinical information, and the type of treatment requested.
Your healthcare provider may believe a treatment is appropriate for you while your insurer determines that the request doesn't meet the plan's coverage criteria.
That's one reason understanding the insurer's specific reason for a denial is so important.
Why Was My Care or Claim Denied?
Insurance denials happen for many reasons, and not every denial means the healthcare service itself was inappropriate.
Common reasons can include:
Prior Authorization Was Missing
The service required authorization before it was provided, but the required process wasn't completed.
Medical Necessity
The insurer determined that the information submitted didn't demonstrate that the service met the plan's medical-necessity criteria.
Missing Information
Medical records, documentation, or other requested information may be incomplete.
Out-of-Network Care
The provider or facility may not participate in your plan's network.
Benefit Exclusion
Your health plan may exclude the particular service or treatment.
Coding or Billing Issue
Eligibility or Coverage Issue
Incorrect or incomplete billing information can sometimes result in a claim being denied.
The insurer may determine that coverage wasn't active on the date the service was provided.
What Is an Appeal?
An appeal is a formal request asking your health insurance company to reconsider a coverage or claim decision.
Depending on the reason for the denial and your plan, an appeal may include additional information supporting why the service should be covered.
This could include:
-
Medical records
-
Test results
-
Treatment history
-
A letter from your healthcare provider
-
Documentation of previous treatments
-
Relevant information requested by your plan
Keep Track of Everything
Create a folder—paper or digital—for:
✔ Denial letters
✔ EOBs
✔ Medical records
✔ Appeal documents
✔ Letters from your provider
✔ Emails
✔ Dates and times of phone calls
✔ Names of representatives you speak with
✔ Confirmation and reference numbers
Good documentation can make it much easier to follow what has happened and what needs to happen next.
Know Your Appeal Rights
Many health plans provide a process for challenging certain coverage decisions.
Depending on your plan and situation, you may have access to an internal appeal, where your insurance company reviews its decision again.
Appeal procedures and deadlines can vary, so follow the instructions included with your denial notice and plan documents.
Don't ignore the deadline listed on your notice.
What Is an External Review?
Sometimes a denied coverage decision may qualify for review by an independent organization outside of your insurance company.
This is called an external review.
External review may be available for certain types of adverse benefit determinations, such as some decisions involving medical necessity, appropriateness, healthcare setting, level of care, or effectiveness of a covered benefit.
Eligibility and procedures depend on your health plan, the type of denial, and applicable federal or state rules.
Your denial notice should provide information about available review rights and how to request them.
What If My Situation Is Urgent?
Some health plans and applicable laws provide expedited review processes when waiting through the standard process could seriously jeopardize a person's life, health, or ability to regain maximum function, or in certain other urgent circumstances.
If you believe your situation may qualify as urgent, contact your healthcare provider and insurance company promptly and ask about expedited review or appeal options.
For a medical emergency, seek appropriate emergency medical care rather than waiting for an insurance determination.
Putting It All Together
When coverage is delayed or denied:
Read the notice → Understand the reason → Contact your insurer → Talk with your provider → Correct missing information if appropriate → Review your appeal rights → Keep records → Consider external review if available
The most important thing is to understand why the decision was made before deciding what to do next.
Questions to Ask Your Insurance Company
When you call, consider asking:
✔ What specifically caused this request or claim to be denied?
✔ What part of my plan or coverage criteria applies?
✔ Is additional information needed?
✔ Can the provider correct or resubmit anything?
✔ Do I have the right to appeal?
✔ What is the deadline?
✔ How do I submit an appeal?
✔ Is an expedited appeal available in urgent circumstances?
✔ If my internal appeal is unsuccessful, could external review be available?
