How to Handle Health Plan Billing Errors and Get Your Money Back

Billing errors in healthcare are too common. Patient advocates estimate that almost half of all medical bills contain at least one error. You don’t have to pay for someone else’s mistake. You can fix a duplicate charge, an incorrect code, or a service you never received. Here’s how to identify, document, and resolve billing errors, and how WellthCare can stop many of them before they hit your wallet.

Step 1: Spot the Error

Start by reading your Explanation of Benefits (EOB) or medical bill carefully. Look for these red flags:

• Duplicate charges – the same service billed twice
• Upcoding – a more expensive code than the service provided
• Unbundled services – separate charges for what should be one procedure
• Services you didn’t receive – check dates and descriptions
• Incorrect insurance adjustments – your plan paid less than it should
• Balance billing – a provider charging you the difference between its full charge and what your plan paid

With WellthCare, many errors get caught before you ever see a bill. Our bill reduction services automatically review charges so overcharges get caught before they reach your wallet.

Step 2: Gather Your Evidence

Before calling anyone, collect your paperwork:

1. Your EOB from the insurer
2. The provider’s itemized bill with service codes
3. Payment receipts (if any)
4. Notes on what you discussed before a procedure
5. Prior authorization numbers or referrals

This paper trail saves you. Without it, you’re relying on memory and the provider’s goodwill, and both can fail.

Step 3: Call the Provider First

Most errors start with the provider’s billing office, not the insurance company. Start there:

• Call the billing department directly
• Politely explain the error, referencing the code and charge
• Ask for a corrected bill or a written explanation
• Request a good-faith adjustment if it’s their mistake

While the dispute is open, ask the billing office in writing to hold the account out of collections.

Pro tip: Write down the name of every person you speak with, the date, and any reference number. Log each call in the WellthCare app, and your care coordination team can help you work through the dispute. WellthCare is a Health-to-Wealth Benefit System where healthcare pays you back.

Step 4: Appeal to Your Insurer

If the provider doesn’t fix it, or the error is on the insurer’s side, file a formal appeal:

1. Call the number on the back of your insurance card
2. Give your claim number and a clear description of the error
3. Submit a written appeal within the deadline, usually 180 days
4. Include copies of all documentation (keep originals)
5. Request a timely written response

For employer-sponsored plans, your HR team can advocate for you. With WellthCare, the system automatically maintains compliance-grade records that are clean and ready to submit.

Step 5: Escalate Smartly

If the insurer denies your appeal or ghosts you, escalate:

• State insurance commissioner – each state has a consumer complaint division
• Employee Benefits Security Administration (EBSA) – for ERISA plans
• Healthcare advocate organizations – some non-profits offer free help

Under ERISA, you have the right to a full and fair review of denied claims, so a denial is not the final word.

Surprise Bills: Your Rights Under the No Surprises Act

Some surprise bills are now illegal. The No Surprises Act, in effect since January 1, 2022, bans balance billing for most emergency services, for non-emergency care from out-of-network providers at in-network facilities, and for air ambulance transport. In those situations you owe no more than your plan’s in-network cost-sharing, and the provider and insurer have to settle the rest between themselves.

If one of these bills still reaches you, call the No Surprises Help Desk at 1-800-985-3059 or file a complaint with CMS. Ground ambulance transport is the main gap: the law does not cover it, so that bill can still surprise you.

How WellthCare Prevents Errors Before They Start

WellthCare eliminates the waste and friction that cause billing errors. Employees use $0-co-pay care before filing claims through their primary plan, so fewer claims can go wrong. When bills do come through:

• Our bill reduction services automatically review charges and work to reduce what you owe
• The app tracks every bill, EOB, and payment, so you never lose a document

WellthCare isn’t just a benefit for when you’re healthy. It also works for you when a bill is wrong.

Final Advice: Act Fast, Stay Organized

Billing errors don’t disappear if you ignore them. Most insurers have strict deadlines, and missing them can cost you your appeal rights. Follow this checklist:

• Review every EOB within 30 days
• Call the provider within 60 days of discovering the error
• File a formal appeal within 180 days of the claim
• Set a reminder to follow up every 2 weeks until resolved

For employers, billing errors drain your healthcare spend. An estimated 20–25% of U.S. healthcare spending goes to waste each year. WellthCare aligns incentives upfront: fewer claims hit the primary plan, and employees skip the administrative nightmare. It’s healthcare that pays you back, including your time.
