Paste your bill text. The AI audits each line for overcharges, bundling violations, duplicate charges, and balance-billing — then drafts a formal dispute letter citing the actual statutes.
What this catches: upcoding, unbundled CPT codes, duplicate charges, balance billing protected by the No Surprises Act (42 USC §300gg-111), nonprofit hospital charity care violations (IRS §501(r)), facility fees billed wrong, math errors, services you never received.
What to do with the letter
Mail it certified, return-receipt requested, to the provider's billing address. Keep a copy.
Wait 30 days for response.
If no response or refusal: escalate to your state insurance commissioner, the No Surprises Help Desk (1-800-985-3059), or the IRS for §501(r) violations at nonprofit hospitals.
For charity care: also send a copy to the hospital's Financial Assistance / Charity Care office.
