About EOBDecode

A calm, primary-source-pinned decoder for the denial codes on your Explanation of Benefits — and an educational appeal-letter scaffold for when a denial is worth contesting.

Why this exists

A denied EOB is one of the most confusing pieces of paper a person can receive — a string of codes like CO-22 or PR-1 with no plain explanation of what it means or what to do. EOBDecodeturns those codes into clear language, points to the official source, and lays out concrete next steps, without the alarmist framing or the “fight the insurer” tone that the moment does not need.

Our approach

Official X12 descriptions transcribed verbatim and pinned to source.
A plain-English layer that explains the meaning and next steps.
An appeal-letter scaffold matched to your plan type and state.
Privacy by design — nothing you look up or type is logged.
