How to dispute a surprise medical bill

Reduce or eliminate an unexpected medical charge.

Step-by-step

1. Step 1: Request an itemized bill

   Hospitals and large providers often send a summary bill. Request an itemized bill showing every CPT code charged. Studies show 30-80% of medical bills contain errors when reviewed line-by-line.

2. Step 2: Check for billing errors

   Common errors: duplicate charges, services not provided, wrong CPT codes, upcoded procedures (a 'short visit' billed as 'long visit'). Compare each line to your actual visit. Mark anything unfamiliar.

3. Step 3: Check the No Surprises Act applies

   Since 2022, the federal No Surprises Act protects most patients from surprise out-of-network bills for emergency care and for non-emergency services at in-network facilities. If you have one of these bills, dispute it at cms.gov/nosurprises. The IDR (Independent Dispute Resolution) process handles it.

4. Step 4: Negotiate cash-pay or financial assistance

   Most hospitals offer 30-60% discounts for cash-pay patients and financial assistance programs (often called 'charity care') for patients under 400% of the federal poverty level. Call the billing office and ask for both.

5. Step 5: Get a written settlement before paying

   Once a number is agreed to, request a written letter showing the agreed amount and what it covers. Pay the agreed amount and keep proof. Do not pay disputed amounts before written agreement.
