## Why medical billing teams annotate a PDF

A biller merges a claim with its EOB and supporting records, extracts the charges into a spreadsheet, and redacts patient identifiers before sending the file on.

**Built for claims.** Whether it's claims, explanations of benefits, superbills, Arthize's annotate pdf keeps the work inside your private workspace. Billing records carry health and financial data; private processing and deletion are essential.

## What matters when you annotate a PDF

You can highlight, comment, draw and add notes.

Annotated files are ideal for review and feedback.
