Confused by a code on your EOB? Decode it.

Those cryptic codes on your Explanation of Benefits — like CO-45 or PR-1 — each mean something specific. Enter one and we'll translate it into plain English, free.

It's usually in the "reason" or "remark" column, next to a charge.

We don't store anything from this. Your full EOB read — every code, what you owe, and what to dispute — is free when you create an account.
