Audit Your Medical Bills and Fight Junk Fees
DeepSeek's web chat is completely free, requires no credit card, and its massive document parser can cross-reference your hospital bill against your insurance Explanation of Benefits (EOB) to find hidden billing errors that cost you thousands.
The Walkthrough
Demand the Real Bill
Call the hospital billing department. Do not accept the "summary" bill. You have a legal right to an Itemized Statement with CPT/HCPCS codes. Request this as a PDF.
"I am requesting a complete Itemized Statement including all CPT codes and revenue codes for my visit on [Date]. Please email it as a PDF."
The OCR Pre-Flight Check
Open the PDF on your computer. Try to highlight the text. If you cannot highlight the numbers (it acts like a single image), the AI will hallucinate the math. You must first run it through your phone's built-in Live Text (iOS) or Microsoft Lens (Android) to convert it to a real, selectable PDF.
Upload to DeepSeek
Go to chat.deepseek.com (create a free account with an email/phone). Click the attachment icon and upload both the Itemized Statement and your Insurance EOB.
Deploy the Auditor Prompt
Paste this exact instruction to force the AI to look for upcoding, unbundling, and duplicate dates:
"Act as a medical billing auditor. I have uploaded my EOB and the hospital's Itemized Statement. 1. Cross-reference the CPT codes. 2. Identify unbundling (billing components separately that should be bundled). 3. Identify duplicate dates or mismatched charges between the EOB and the bill. 4. Draft a polite, firm dispute letter to the billing department citing the exact discrepancies."
Deploy the Charity Care Shield
If the bill is still too high, ask the AI to invoke federal law to pause collections:
"Draft a formal request to the hospital's billing department asking for their Financial Assistance Policy (FAP) application and plain-language summary, as required by IRS Section 501(r) for nonprofit hospitals. State that I will pause payment until I receive this."
⚠️ What Breaks
This is not legal or medical advice; it is a math and logic check. DeepSeek does not have a hard daily message limit, but during peak US evening hours (6 PM - 9 PM EST), you may hit a "Server Busy" soft limit. If this happens, wait 10 minutes and retry. The biggest failure mode is OCR errors: if you upload a scanned image PDF without converting it to selectable text first, the AI will confidently invent wrong prices. Always verify the PDF text is highlightable before uploading.
