Before You Pay That Medical Bill: Check Your Medicare Summary Notice

A medical bill arrives in the mail. Before you write the check, there’s another document Medicare beneficiaries should know how to read.

You open the mailbox and there it is.

A bill from a doctor, hospital, laboratory or other healthcare provider.

Maybe you recognize the service.

Maybe you don’t.

Maybe the amount is much higher than you expected.

The natural reaction is to assume:

“Medicare must have processed it, so this must be what I owe.”

Not necessarily.

Here’s something I wish more Medicare beneficiaries knew:

If you have Original Medicare, one of the first things you should do before paying an unexpected medical bill is compare it with your Medicare Summary Notice.

Your Medicare Summary Notice — commonly called an MSN — can help you understand what was billed to Medicare, what Medicare approved, what Medicare paid, and what Medicare says you may owe.

And despite the word “Notice” appearing on it:

Your Medicare Summary Notice is not a bill.

Let’s look at what it is — and how you can use it.

What Is a Medicare Summary Notice?

If you have Original Medicare, Medicare sends you a Medicare Summary Notice every three months when you receive Medicare-covered services during that period.

The MSN summarizes claims submitted to Medicare for your care.

It shows information including:

  • The services or supplies providers billed to Medicare
  • Whether Medicare approved the claim
  • What Medicare paid
  • The maximum amount you may be billed
  • Information about denied claims
  • Information about your appeal rights

You can see Medicare’s explanation of the Medicare Summary Notice.

You can also access Medicare claims information through your Medicare.gov account.

What you can do: Don’t automatically throw your Medicare Summary Notice into the “insurance paperwork” pile. It contains information worth reviewing.

First Things First: An MSN Is NOT a Bill

This deserves to be repeated.

Do not send money because you received a Medicare Summary Notice.

The MSN is Medicare’s explanation of how claims submitted during that period were processed.

Your healthcare provider may separately send you a bill for your portion.

That’s where the MSN becomes useful.

You can compare the provider’s bill with what Medicare says happened with the claim.

What you can do: Put the provider’s bill next to your Medicare Summary Notice and compare them before paying an amount you don’t understand.

What Should You Look For?

You don’t have to understand every code or abbreviation on the document.

Start with a few basic questions.

1. Do You Recognize the Provider?

Look at the names of the doctors, hospitals, laboratories, suppliers and other providers who submitted claims.

Ask yourself:

“Did I actually receive care from this provider?”

Sometimes the name appearing on a Medicare claim isn’t identical to the name you recognize from the doctor’s office. A practice may bill under a larger organization or health system.

So an unfamiliar name doesn’t automatically mean something is wrong.

But it is worth investigating.

What you can do: If you don’t recognize a provider or service, don’t ignore it. Call the provider or Medicare and ask questions.

2. Do You Recognize the Service?

Look at the description and date of service.

Does it correspond with an appointment, test, procedure or medical service you remember receiving?

Pay particular attention to services you don’t recognize.

Medicare encourages beneficiaries to review their Medicare claims for accuracy.

This isn’t only about billing mistakes.

Reviewing your claims can also help identify potential Medicare fraud or misuse of your Medicare number.

Medicare provides guidance about how to spot and report Medicare fraud and abuse.

What you can do: If you see a service you’re certain you didn’t receive, investigate it promptly.

3. Was the Claim Approved?

Your MSN tells you whether Medicare approved the service.

If Medicare didn’t pay something, don’t stop at:

“Medicare denied it.”

Find out why.

There may be an explanation on the MSN.

A denial doesn’t necessarily mean the situation is hopeless or that you automatically owe whatever amount appears on a provider bill.

There are circumstances in which Medicare’s decision can be appealed.

Medicare explains the Original Medicare appeals process.

What you can do: Read the explanation associated with a denied claim before deciding what to do next.

4. Look at “Maximum You May Be Billed”

This is one of the most useful pieces of information on the MSN.

Medicare’s MSN includes a column showing the maximum amount you may be billed for a claim.

Compare that amount with the bill you received from the provider.

If the provider’s bill is higher than what you expected based on the MSN, don’t simply assume you need to pay it.

Call the provider’s billing department and ask them to explain the difference.

There may be another insurer involved, a Medigap claim still being processed, or another reason the balances don’t match yet.

What you can do: Compare the amount the provider is requesting with the information Medicare provides before paying an unexpected balance.

5. If You Have a Medicare Supplement, Give It Time to Process

If you have Original Medicare plus a Medicare Supplement — also called Medigap — there can be more than one step involved in processing your claim.

Medicare processes its portion first.

Information may then be sent to your Medigap insurer so it can determine what it owes under your policy.

That means a provider’s initial statement isn’t always the end of the story.

If your Medigap policy should cover some or all of the remaining Medicare-approved cost, make sure that claim has been processed before assuming the provider’s current balance is your final responsibility.

Medicare explains how Medigap works with Original Medicare.

What you can do: If you receive a bill shortly after Medicare processes a claim, verify whether your Medicare Supplement has processed its portion before paying an unexpected balance.

What If You Have Medicare Advantage?

Here’s an important distinction.

The Medicare Summary Notice we’re discussing is for people with Original Medicare.

If you’re enrolled in a Medicare Advantage plan, your plan will generally provide its own Explanation of Benefits, often called an EOB.

The concept is similar:

Don’t automatically treat an EOB as a bill.

Use it to understand how your plan processed the claim, what the provider charged, what the plan paid and what the plan says you may owe.

If something doesn’t make sense, contact your Medicare Advantage plan and the provider.

What you can do: Know which document applies to you:

Original Medicare → Medicare Summary Notice

Medicare Advantage → Your plan’s Explanation of Benefits

What If Medicare Denied Something?

This is another reason not to immediately pay a large bill.

If Original Medicare denies a service you believe should have been covered, you have the right to appeal Medicare’s decision.

Your MSN contains information about how and when to appeal.

Appeals have deadlines, so don’t put a questionable denial aside for six months and assume you can deal with it later.

Medicare provides step-by-step information about filing an Original Medicare appeal.

If you have Medicare Advantage, the appeal process goes through your Medicare Advantage plan and follows different procedures. Medicare provides separate guidance for Medicare Advantage appeals.

What you can do: If you believe something was incorrectly denied, read your notice and pay attention to the appeal deadline.

Watch for Something Else: Medicare Fraud

Reviewing your MSN isn’t only about protecting your wallet.

It’s also one way to protect your Medicare benefits.

Look for:

  • Services you never received
  • Medical equipment you never ordered
  • Providers you’ve never seen
  • Duplicate services
  • Dates that don’t make sense

Again, an unfamiliar item isn’t automatically fraud.

Ask first.

But if you discover that Medicare was billed for something you definitely didn’t receive, don’t ignore it.

Medicare provides instructions for reporting suspected Medicare fraud.

What you can do: Treat your Medicare number like other important personal information, and review claims regularly for services you don’t recognize.

Before You Pay an Unexpected Medical Bill, Ask These 6 Questions

Keep this list somewhere handy:

  1. Does this bill match a service I actually received?
  2. Has Medicare processed the claim yet?
  3. What does my Medicare Summary Notice say I may owe?
  4. If I have Medigap, has my Medicare Supplement processed its portion?
  5. If Medicare denied the service, why was it denied — and do I have appeal rights?
  6. Does anything on the claim look unfamiliar or incorrect?

If something doesn’t add up, make a phone call before writing a check.

An Easy Habit That Can Help

You don’t need to become an expert in medical billing.

Create a simple system.

When you receive an unexpected medical bill:

Bill → Medicare/EOB → Supplement → Pay

In other words:

1. Review the provider’s bill.

2. Compare it with Medicare’s MSN or your Medicare Advantage EOB.

3. If you have secondary coverage, make sure that coverage has processed the claim.

4. Then determine what you actually owe.

That extra few minutes can be worthwhile when something doesn’t look right.

The Bigger Medicare Lesson

Most people spend a lot of time learning about Medicare before they enroll.

What happens afterward matters just as much.

Understanding your Medicare Summary Notice is one of those small skills that can help you become a better healthcare consumer.

You don’t have to understand every billing code.

You don’t have to know every Medicare regulation.

You simply need to know enough to stop when something doesn’t look right and ask:

“Is this really what I owe?”

Why We’re Talking About This

There are things people don’t always learn when they enroll in Medicare.

We’re going to talk about them.

Not to make Medicare more complicated — but to help you understand the questions to ask, recognize potential problems and make more informed decisions about your healthcare.

Because sometimes avoiding an unexpected healthcare bill starts with knowing what to ask before you pay it.
