Understanding Your Explanation of Benefits (EOB): The Key to Avoiding Medical Billing Mistakes

This week, I want to talk about something that many people receive from their insurance company but often ignore: your Explanation of Benefits, also known as an EOB.

I know insurance terminology can be confusing, and “EOB” sounds like another complicated insurance acronym. But reviewing your EOBs is one of the most important things you can do to protect yourself from overpaying for medical care.

What Is an Explanation of Benefits (EOB)?

An Explanation of Benefits is a statement from your insurance company that shows:

• The services you received
• How your claim was processed
• What the insurance company paid
• Any discounts applied
• What portion you may owe

An EOB is not a bill.

Instead, it’s a record of how your insurance company handled your claim.

Why Reviewing Your EOB Matters

I cannot stress this enough: Always review your EOBs.

Mistakes happen more often than people realize.

I’ve seen claims that:

• Were denied incorrectly
• Showed the patient had no insurance when they actually did
• Applied the wrong copay or deductible
• Processed services incorrectly
• Included billing errors

Reviewing your EOB helps you catch these issues before you pay a bill you don’t actually owe.

Compare Your EOB to Your Medical Bill

Once you receive a bill from your doctor’s office, hospital, or lab, compare it line by line to your EOB.

Ask yourself:

• Do the services match?
• Were the insurance payments applied correctly?
• Were network discounts included?
• Does the patient responsibility amount match?

The amount you owe on your provider bill should generally match what your EOB says you owe.

If it doesn’t, ask questions.

Mistakes Happen More Than You Think

Insurance companies process millions of claims every year.

Doctors’ offices process thousands of bills every month.

Unfortunately, mistakes happen on both sides.

I’ve helped many clients discover:

• Incorrect charges
• Services they never received
• Payments that weren’t applied correctly
• Insurance claims that should have been paid but weren’t

By simply reviewing your paperwork, you can potentially save yourself hundreds—or even thousands—of dollars.

My Recommendation: Print Everything

I know we live in a digital world, but I personally like to print my EOBs and compare them to my provider bills.

There’s something helpful about physically reviewing:

• The line items
• The charges
• The payments
• The discounts
• The patient responsibility

Think of it like balancing your checkbook or reconciling your bank statement.

You wouldn’t pay a credit card bill without reviewing the charges first, right?

Your medical bills deserve the same attention.

What If Something Doesn’t Look Right?

If something seems off:

1. Call the provider’s billing office.
2. Call your insurance company.
3. Ask questions.
4. Request corrections if needed.

Sometimes a simple phone call can resolve an issue quickly.

Other times, there may be a larger billing error that needs to be corrected.

I Help Clients With This All the Time

Many of my clients reach out when they receive confusing bills or EOBs.

While I cannot access your claims directly due to HIPAA privacy laws, you can always send me your documents and I’ll help you understand what you’re looking at.

Sometimes it’s an insurance issue.

Sometimes it’s a provider billing issue.

Sometimes it’s simply a misunderstanding of how the plan works.

But reviewing your EOB is always the first step.

Final Thoughts

Your Explanation of Benefits is more than just paperwork.

It’s one of the best tools you have to:

• Understand how your insurance works
• Catch billing mistakes
• Avoid overpaying
• Verify your claims were processed correctly

Take a few minutes to review every EOB you receive.

Your wallet will thank you.
