Upload your bill. We check every line against Medicare's published national rate and draft a letter asking your hospital to explain the difference.
Example · CPT 99285 · ER visit, level 5
"You billed $2,450 for CPT 99285, a code Medicare's national fee schedule sets at $171. Please provide an itemized explanation of this charge."
Medicare publishes a national rate for the codes on your bill: doctors' services, lab tests and Part B drugs, from the official CMS fee schedules. It's not a "fair price" — it's a documented, government benchmark nobody can dispute the source of. Hospitals can add separate facility fees, which is exactly why the letter asks for an itemized explanation instead of accusing anyone.
You don't need to know what a CPT code is. We look it up for you.
01A PDF or a photo works. From any US hospital, ER, or urgent care.
02Each charge is compared to Medicare's published national rate — a public number, not our opinion.
03Addressed, dated, and citing the exact codes — ready to print and mail.
The audit is free. You only pay if you want the letter. No subscription.

Have another bill to check?
Yes. Medicare rates are a public, government-published benchmark. Citing them to request an itemized review is a normal, lawful practice.
Disputing a bill directly with a hospital's billing department typically pauses collections while the review is pending. Confirm directly with your hospital's billing office.
The letter requests a written response within 30 days. The Pro plan includes a follow-up letter template if you don't hear back.
Your bill is processed to extract the data needed for your letter. We don't keep the original file, and the extracted information is stored encrypted. If you don't buy, it is automatically deleted after 48 hours. If you do buy, it is kept for 30 days so you can re-download your documents, then automatically deleted. See our Privacy section for details.
No. CureMyBill generates a request for itemized review that you send yourself. It isn't legal advice.
