How do I report a suspicious Medicare billing error without getting in trouble myself?

Question

Cynthia Nakaya · Accepted Answer

Don't let the fear of retaliation prevent you from exposing the possible wrongdoing of someone in a position of trust over you. The False Claims Act protects you.

Fraud, waste, and abuse hurts us all. It takes courage to report something you think is wrong, but it's the right thing to do. We all must do our part to expose corruption in the system because, in the end, it's our money being misused. 

To report something you think is wrong, you have several options. You can call your provider's office and inquire about the charge. They may be able to explain it. If you feel uncomfortable or sense your concern was brushed off, call your plan's member services number and speak with a supervisor about the billing error. You may also call Medicare to voice your concerns.  These actions take time, but after you call, you'll feel better knowing you did the right thing.

You will not get in any trouble for reported suspected fraud or billing errors to Medicare. 

If you believe this is an honest billing error, contact the billing agent first to try and get it corrected. You can also contact your agent for assistance in determining if an actual billing error occurred. 

If you do suspect either fraud or wastefulness, you can contact Medicare directly at 1 800 Medicare. You complaint is completely confidential.

There is a law that protects folks from intimidation when it comes to a health care or Medicare-related incident or grievance. It is the “Whistleblower” regulation. No worries!

Diana Garner · Answer

You can contact the Senior Medicare Patrol (SMP) or the Office of Inspector General (OIG) hotline. Both allow for reporting without revealing personal information.

Dana Dane · Answer

Sometimes there are billing errors. In my experience, the number one error is coding something as routine when it should be coded as medically necessary. A call to your provider is usually enough to fix the problem. They simply add the correct code and rebill. If you are being charged for services not rendered or items not received, for example, I would first contact your agent. In this case, you may also contact the provider. The next step would be to report it to CMS which is Medicare.

Medicare encourages beneficiaries to report fraud or billing mistakes — and you’re protected when doing so in good faith. You won’t get in trouble for reporting something suspicious, even if it turns out to be a mistake.

Call 1-800-633-4227

If you prefer, you can report without giving your name — though giving your info may help them investigate more thoroughly.

Katheryn Evans · Answer

Call the number listed on the practitioner's bill and ask questions so you understand why they are asking for that specific dollar amount to be paid.

If you are not satisfied, call your insurance company and share your concern.

If you are still not satisfied call your state insurance commissioner and CMS and file a complaint.

You can call Medicare. You can call or go online to the Department of Health and Human Services. They have a fraud hotline. There is the Senior Medicare patrol that can also assist you with this. I think the best way is to contact Medicare. They can assist you and provide you with all of your options.

Vachik Chakhbazian · Answer

begin by contacting the healthcare provider or billing department first to inquire about the error and seek resolution. If the issue persists, you can then report the error to the Medicare Administrative Contractor (MAC) or the Senior Medicare Patrol (SMP) for further investigation. You can also submit a complaint through Medicare.gov.

Randy Hill · Answer

Here’s what to do if you spot something fishy on your Medicare bill:

1. Double-check the bill.
Look at your Medicare Summary Notice (MSN) or Explanation of Benefits (EOB).

Did you get charged for something you didn’t receive?

Did they bill the same thing twice?

Did the date look wrong?

2. Call your doctor or provider first.
Sometimes billing mistakes happen by accident.
Ask: “Can you help me understand this charge?”

3. Still looks wrong? Report it safely.
You can call Medicare’s fraud hotline at
1-800-MEDICARE (1-800-633-4227)
or
1-800-HHS-TIPS (1-800-447-8477) (Health & Human Services)

You can stay anonymous if you want and you will not get in trouble for asking questions or reporting a possible error.

Why this matters:

Medicare loses billions of dollars every year to mistakes and fraud.
When you speak up, you’re helping protect your money and everyone else’s too.

If you’d like, I can help you review your Medicare statement and make sure everything looks right no pressure, no cost.

Kimberly Hargis · Answer

Call the Medicare 1-800-MEDICARE helpline.

You can also report it online through Medicare.gov or through the Internet Crime Complaint Center
