How to Dispute a Medical Bill

Question

Accepted Answer

Medical billing errors are surprisingly common. Studies suggest up to 80% of medical bills contain errors. Understanding your rights can save you significant money.

Steps to dispute a medical bill:

Request an itemized bill. Ask for a detailed breakdown of every charge, including procedure codes (CPT codes) and diagnosis codes (ICD codes).

Review for errors. Common errors include duplicate charges, charges for services not received, incorrect procedure codes (upcoding), and charges for a private room when you had a shared room.

Compare with your insurance explanation of benefits (EOB). Check what your insurance covered and what adjustments were applied.

Appeal insurance denials. If your insurance denied coverage, file an internal appeal. If denied again, request an external review by an independent third party.

Negotiate. Many providers will accept a lower payment, especially for uninsured or underinsured patients. Ask about cash-pay discounts, payment plans, or financial assistance programs.

Request financial assistance. Nonprofit hospitals are required to have financial assistance policies. Ask about charity care programs.

Legal protections:

No Surprises Act — Protects you from surprise bills for emergency services and certain out-of-network charges at in-network facilities.

State balance billing laws — Many states have additional protections.

Fair Debt Collection Practices Act — Protects you if the bill goes to collections.

Do not ignore medical bills. Unpaid medical bills can be sent to collections and damage your credit.
