X12 271 Eligibility Response Reader
Read an X12 271 eligibility response without sending it anywhere.
Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Coverage
- Active, individual, in network
- Deductible
- $1,500.00 calendar year; $1,112.40 remaining
Result: 1 active person reported across 3 benefit lines.
Answer the questions this way to reach that result. Your own answers give your own.
Inputs and output
- What you enter
One X12 271 005010X279A1 text file, or a response pasted into the page, up to 50 MB. The response remains in the browser tab.
- What you get
- A coverage and benefit summary, every EB benefit line with its raw codes and dates, response error counts, and full or redacted CSV downloads. Redacted downloads mask names and member IDs.
What this is
The reader turns coverage, plan identifiers, benefit amounts, percentages, dates, service types and network status into a plain summary and a checkable table.
When to use it
Use this after receiving a 271 from a payer or clearinghouse and before quoting benefits. Raw codes remain beside project-authored labels so you can verify what the file actually says.
