We personalize it to your situation. Here's a redacted example.
"My hospital charged me $1,800 for a blood test that my insurance said should cost $140. BillFight wrote the letter in under a minute — the billing department reduced it to $160 within three weeks."
"Got a surprise $2,400 bill from an out-of-network anesthesiologist after surgery at an in-network hospital. BillFight cited the No Surprises Act, and it was removed entirely."
"My insurance denied my MRI claim. Used BillFight's letter — they cited the right guidelines and the appeal was approved within two weeks. Paid for itself many times over."
If any of these sound familiar, you have grounds to dispute.
In-network hospital, out-of-network doctor you never chose. The No Surprises Act (2022) prohibits this — and we cite it.
Charged for services you didn't receive, double line items, or fees that don't match your itemized bill.
Your insurer denied a claim. You have the right to a formal internal appeal — our letter makes it official.
Your Explanation of Benefits doesn't match the hospital bill. We demand reconciliation in writing.
The same item or procedure appears twice on your bill. Request immediate correction and a refund.
Insurance covered less than expected after a pre-authorization or network agreement. Formally contest it.
One letter. One price. No surprises — we'd never do that to you.
BillFight provides document preparation assistance, not legal advice.
Takes 2 minutes. You'll pay $29 after we save your details.
