6 Medical Bills You Have the Right to Dispute — and Win
By Erica Coleman · May 31, 2026
Studies consistently find that up to 80% of medical bills contain errors, duplicate charges, or incorrect billing codes. Most patients pay without question. Here are six situations in which you have a documented right to dispute what you have been billed — and where the law is on your side.
1. Bills that exceed your good faith estimate by $400 or more
Under the No Surprises Act, which took effect in 2022, healthcare providers are required to give uninsured or self-pay patients a good faith estimate of expected costs before non-emergency services. If your final bill exceeds that estimate by $400 or more, you are legally entitled to dispute it through the federal patient-provider dispute resolution process at CMS.gov. An independent third party reviews the bill and determines an appropriate amount. Providers often settle before the review is complete.
2. Duplicate charges
Request an itemized bill — not the summary statement — from every provider after a hospital stay or complex procedure. Look specifically for the same service billed twice on the same date. Duplicate charges are among the most common billing errors and among the easiest to dispute. Hospitals are required by law to provide an itemized bill within 30 days of your written request.
3. Upcoding — charges for services more expensive than what you received
Upcoding occurs when a provider bills for a higher-level service than what was actually performed — for example, billing for a complex evaluation when a routine visit occurred. Compare the CPT codes on your itemized bill against the description of what actually happened during your appointment. If the codes don’t match your experience, you can dispute them. The hospital pricing tool at PatientRightsAdvocate.org allows you to look up the correct price for your procedure at your specific hospital.
4. Out-of-network charges at in-network facilities
Nearly 60% of Americans have received a surprise bill for out-of-network services at a hospital they specifically chose because it was in-network. This typically happens when an anesthesiologist, radiologist, or specialist involved in your care is not in your plan’s network, even though the hospital is. Under the No Surprises Act, for emergency care and certain non-emergency services at in-network facilities, you cannot be charged more than your in-network cost-sharing amount. If you received such a bill, contact your insurer and the provider and cite the No Surprises Act.
5. Bills for services that weren’t rendered
Check every line on your itemized bill against your actual experience. Common phantom charges include items like a $15 “box of tissues,” charges for medications brought from home, or fees for consultations by physicians you never saw. If you were charged for something you didn’t receive, dispute it in writing with your provider and follow up with your insurer.
6. Bills that exceed your state’s financial assistance income thresholds
Most nonprofit hospitals — which represent the majority of US hospital beds — are required by their tax-exempt status to provide charity care or financial assistance to patients below certain income thresholds, typically 200-400% of the federal poverty level ($31,920–$63,840 for individuals in 2026). If you have a large bill and your income falls within these ranges, you may qualify for significant reduction or elimination of the debt. Ask the hospital’s billing department for their financial assistance application — it exists at every nonprofit hospital, and they are required to tell you about it.
Write dispute letters, keep copies of everything, and follow up in writing rather than by phone. If you suspect systematic overcharging or have a large bill you cannot resolve, patient advocacy services like Solace Health and Medical Bill Rescue negotiate on behalf of patients — typically for a percentage of the amount saved.
