Federal Patient Rights (All States)
📋 You Always Have These Rights
✓
Right to Itemized Bill: Under HIPAA, you can request an itemized statement of every charge within 30 days. Hospitals must provide it.
✓
No Surprises Act (2022): Out-of-network emergency care can't be billed more than in-network rates. You can dispute surprise bills.
✓
Right to Dispute: You can formally dispute any charge. The provider must respond within 30 days and cannot send to collections during dispute.
✓
Price Transparency: Since 2021, hospitals must publish standard charges online. You can compare before disputing.
✓
Charity Care: Nonprofit hospitals (most are) must offer financial assistance programs. Ask directly — many won't tell you.
✓
Collections Protection: Medical debt under $500 was removed from credit reports (2023 rule). Disputed bills cannot be collected during review.
Common Questions
Everything you need to know before using BillAudit.
Is my medical data safe? ▼
Yes. BillAudit runs entirely in your browser. Your bill data is stored only on your device using localStorage — it never leaves your phone or computer. We have no server, no database, no account. Zero data collection.
I don't have an itemized bill. Can I still use this? ▼
Absolutely. Select "No" when asked if you have an itemized bill. BillAudit will automatically generate a formal demand letter requesting your itemized statement — which is your legal right under federal law. Getting that itemized bill is step one.
Is this legal advice? ▼
No. BillAudit is an educational tool that helps you identify common billing errors and understand your rights. It does not provide legal advice. For complex situations involving collections or legal disputes, consult a patient advocate or attorney.
Will disputing my bill hurt my credit? ▼
No — and it's legally protected. While a dispute is open, the provider cannot send your bill to collections. Additionally, medical debt under $500 was removed from credit reports under 2023 federal rules. Disputing is your right.
What if the hospital ignores my letter? ▼
You have escalation options: (1) File a complaint with your state's insurance commissioner, (2) File with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov — free and effective, (3) Contact your state attorney general's office. Hospitals respond to CFPB complaints very quickly.
What does the Pro plan include? ▼
Pro gives you unlimited bill audits, unlimited dispute letter generation, all 50 state patient rights guides, and access to all future error detectors we add. The free plan allows 1 audit with error detection only — the dispute letter requires Pro.
How accurate are the error detections? ▼
BillAudit flags potential errors based on 12 documented billing patterns — duplicate charges, round-number suspicion, vague line items, etc. These are starting points for your dispute, not guaranteed errors. Always verify each flag against your own records before disputing.
Can I use this for insurance denials too? ▼
BillAudit currently focuses on itemized billing errors. Insurance denial appeals are a different process. In your notes section, mention if a service was denied — the dispute letter will include language invoking the No Surprises Act and your right to appeal.
Still have a question?
Medical billing is complicated. If you have a specific situation not covered here, your state's Department of Insurance has free consumer helplines.
