FAQ
Are these dispute letters free?
Yes. Every letter is free to read and copy, with no account or paywall.
Is this legal advice?
No. These are general educational templates, not advice for your situation. Confirm the rule and deadline that apply to you, and consider a patient advocate or attorney.
Does the No Surprises Act cancel a surprise bill?
It limits most surprise out-of-network charges to your in-network cost-share, but you still owe that share and usually must flag the bill in writing.
Will disputing hurt my credit?
Disputing with the provider does not report to bureaus. Paid medical collections, unpaid amounts under $500, and debt under a year old are no longer reported.
