Patient Resources — Patient Rights & Legal

Medical billing errors are remarkably common. Studies have found that a significant percentage of hospital bills contain mistakes — and most patients never catch them. Whether your bill contains an outright error or you simply cannot afford to pay it, you have more options than you may realize.

Step 1: Request an Itemized Bill

The first thing to do when you receive a medical bill is request a fully itemized statement — a line-by-line breakdown of every charge. You are entitled to this by law. The summary bill you typically receive first says things like “room and board” or “laboratory services” but gives no detail. The itemized bill shows exactly what you were charged for, including the billing codes used for each service.

Step 2: Get Your Explanation of Benefits from Your Insurer

If you have health insurance, your insurer will send you an Explanation of Benefits (EOB) after your provider submits a claim. The EOB shows what was billed, what your insurer paid, what was written off, and what you owe. Compare the EOB carefully to your itemized bill — discrepancies between the two are common and worth investigating.

Common Medical Billing Errors to Look For

  • Duplicate charges — the same service billed more than once
  • Upcoding — billing for a more expensive service than what was actually provided
  • Unbundling — charging separately for services that should be billed together at a lower rate
  • Services not rendered — being charged for tests or procedures that didn’t happen
  • Wrong patient information — incorrect insurance ID, date of birth, or diagnosis code
  • Operating room or recovery room time errors — being charged for more time than actually used
  • Incorrect diagnosis or procedure codes — codes that don’t match what actually occurred

Step 3: Contact the Billing Department

If you find an error or have questions about a charge, call the hospital or provider’s billing department. Be specific — reference the line item, the date of service, and why you believe the charge is incorrect. Keep notes of every conversation including the date, the name of the person you spoke with, and what was said. Follow up in writing to create a paper trail.

Step 4: File an Appeal with Your Insurance Company

If your insurer denied a claim or paid less than you expected, you have the right to appeal. The denial letter will explain the reason and the appeals process. File your appeal in writing and include supporting documentation — your doctor’s notes, a letter of medical necessity, or relevant research supporting the treatment. Most insurers have multiple levels of appeal, and you can also request an independent external review if your internal appeals are denied.

Step 5: Negotiate the Bill

Medical bills are often negotiable — especially if you are uninsured or underinsured. Hospitals routinely accept less than the full billed amount. You can ask the billing department what the Medicare rate or the insured rate for the service is — and request that you be charged that amount instead. You can also ask for a prompt-pay discount if you can pay a lump sum, or negotiate a payment plan.

Step 6: Ask About Financial Assistance

Nonprofit hospitals are required by law to have charity care programs — financial assistance for patients who cannot afford to pay. Even for-profit hospitals often have assistance programs. Ask the billing department specifically about financial assistance, charity care, or hardship programs. You may qualify for a significant reduction or complete forgiveness of your bill based on your income.

Step 7: Hire a Medical Billing Advocate

If you are dealing with a large or complex bill, consider hiring a medical billing advocate — a professional who reviews bills for errors and negotiates with hospitals and insurers on your behalf. Many work on a contingency basis, taking a percentage of whatever they save you. The Patient Advocate Foundation and similar organizations can help connect you with resources.

Step 8: File a Complaint if Necessary

If you believe you have been improperly billed and the provider will not correct it, you can file a complaint with your state insurance commissioner (for insurance issues), your state attorney general’s consumer protection office, or the Centers for Medicare & Medicaid Services (CMS) if the provider receives federal funding.
