EDI (Electronic Data Interchange) - 837P / 835: Electronic Data Interchange

Definition
The standard file format used for computer-to-computer exchange of healthcare documents.

Overview

Why it Matters

This is the "language" your software speaks. If you want to automate billing, you must understand EDI.

How it Works

Your software compiles data into an 837P text string and uploads it to the clearinghouse.

Code Comparison

Comparison: EDI vs. API

EDI: Old school, batch processing, standard across all US healthcare.

API: Modern, real-time, varies by company.

Common Questions

  • Formatting Errors: One missing character in an EDI file can cause the entire batch of 500 claims to fail.
  • Use a "Clearinghouse" that validates your EDI files before they go to the payer.
