Before you upload a bill or EOB
Remove names, member IDs, account numbers, dates of birth, addresses, barcodes, and other identifiers you do not need explained. The file is sent to Anthropic to create the report. Anthropic's standard API policy provides automatic deletion within 30 days, but policy-enforcement, legal, and other published exceptions can be longer. Policy-flagged inputs and outputs may be retained for up to two years and associated classification scores for up to seven years. Medical Bill Reader does not claim zero-data-retention terms or a Business Associate Agreement and is a direct-to-consumer tool, not a HIPAA-covered service.

What is this?
An AI-assisted tool that organizes legible medical-bill fields, explains unfamiliar terms, and identifies specific items to verify.
Who needs it?
Patients who received a confusing medical bill and want to understand what they were charged for before paying or disputing.
Bottom line
Upload a supported medical bill for an AI-assisted first pass. Verify important findings against the source; results are not financial or medical advice.
How does AI medical bill analysis work?
Upload a supported medical bill or EOB and the AI attempts to organize legible line items, billing codes, and insurance fields into a plain-language report.
Files are sent over encrypted HTTPS through the application to Anthropic solely to generate the requested report. Medical Bill Reader does not intentionally save the document in its own database. The tool accepts JPEG, PNG, WebP, and PDF files up to 10 MB. AI output can omit or misread text, so compare every important finding with the original document.
What are the most common medical billing errors?
Common issues worth checking include apparent duplicate line items, incorrect patient or insurance information, missing payments, and services or quantities you do not recognize. Coding questions require the underlying records and payer rules.
CMS advises comparing the provider bill with the Explanation of Benefits, checking that the services match what you received, and contacting the provider or insurer when amounts do not match. An AI flag is only a prompt to verify the source records; it does not establish that a charge is wrong.
What do CPT codes mean on a medical bill?
CPT (Current Procedural Terminology) codes identify medical procedures and services. The code alone does not establish what you should owe because payment depends on the claim, network, plan, and other billing details.
CPT is maintained by the American Medical Association. CMS recommends comparing the bill and EOB with the care and supplies you received, and asking the provider or insurer about anything that does not match. Use the report to locate items for that review, not as a payment determination.
What happens to my data when I upload a medical bill?
Bills are transmitted over encrypted HTTPS through the application to Anthropic for your requested explanation. They are not sold or used for advertising, and Medical Bill Reader does not intentionally store bill documents in its own database.
No account or login is required. The document may contain identifying, health, insurance, and financial information. Redact fields you do not need explained and read the Consumer Health Data Privacy Notice before uploading. Bill content, filenames, report text, and analysis activity are not sent to analytics or advertising systems; Anthropic and infrastructure providers process data under their terms.
Important: This tool provides general explanations of medical billing codes and charges for informational purposes only. It is not financial or medical advice. For billing disputes, contact your healthcare provider or insurance company directly.

Frequently Asked Questions About Medical Bills
What is Medical Bill Reader?
Medical Bill Reader generates an AI-assisted report from a supported medical bill or EOB. It attempts to identify visible codes, charges, insurance fields, and patterns that may be worth verifying.
Is my medical bill data kept private?
Documents are transmitted securely to Anthropic for analysis. They are not sold or shared for advertising, and Medical Bill Reader does not intentionally store them in its own database. Anthropic's standard API policy provides automatic deletion within 30 days, with longer policy-enforcement, legal, and other published exceptions. Policy-flagged inputs and outputs may be retained for up to two years and associated classification scores for up to seven years. Medical Bill Reader does not claim zero-data-retention terms or a Business Associate Agreement. Redact identifiers you do not need explained and see the Consumer Health Data Privacy Notice for details.
What medical billing codes does the tool explain?
The tool attempts to identify CPT, ICD-10-CM, and HCPCS codes when they are legible. Verify each code and description against the original document and provider or insurer records.
Can Medical Bill Reader detect billing errors?
The tool may identify apparent duplicate lines, mismatches, or unfamiliar fields for review. It cannot determine from a bill alone that coding, coverage, or a charge is wrong. Confirm every concern with the provider or insurer before taking action.
Is Medical Bill Reader a substitute for professional advice?
No. Medical Bill Reader provides general explanations of visible medical-billing fields, codes, and charges for informational purposes only. It is not financial or medical advice. For billing disputes, contact your healthcare provider, insurance company, or a qualified medical billing advocate.
