}Quick Summary: Process employer benefit enrollments, terminations, and demographic modifications with high-speed 834 EDI to JSON parsing. Validates strictly against ANSI ASC X12 Standards (005010) with sub-5ms in-memory response times.
Specification & Structural Breakdown
Technical Summary: Validates strictly against ANSI ASC X12 Standards (005010). Payloads are parsed in memory and return clean, typed JSON in milliseconds with zero data logged.
The ANSI X12 834 transaction set is mandated under HIPAA for exchanging healthcare benefit enrollment and member maintenance between employers, unions, and insurance carriers.
Parses INS segments for maintenance type (021=Addition, 024=Cancellation/Termination, 001=Change, 030=Audit).
Extracts HD health coverage loops with insurance line codes (HLT=Health, DEN=Dental, VIS=Vision, RX=Pharmacy) and plan coverage dates.
| Segment | Description | Key Elements Extracted | Usage |
|---|---|---|---|
| BGN | Beginning Segment | BGN01 (00=Original, 15=Re-Submission), BGN02 (Reference ID), BGN03 (Date) | File identification |
| INS | Member Level Detail | INS01 (Y=Subscriber, N=Dependent), INS02 (18=Self), INS03 (021=Add, 024=Term) | Maintenance action |
| NM1 | Member Demographics | NM101 (IL=Insured), NM103 (Last), NM104 (First), NM109 (SSN/ID) | Member identity |
| HD | Health Coverage | HD01 (021=Add, 024=Term), HD03 (HLT/DEN/VIS/RX Coverage Type) | Elected benefits |

Rules:
- Send the request with a 2-second timeout.
- Parse the standard envelope { success, data, meta: { latency_ms, version } }.
- On failure, read { success: false, error, code } and branch on the code.
- Do not retry 4xx responses; surface the error code to the caller.
- Treat invalid-but-well-formed payloads as HTTP 200 with data.valid === false.Frequently Asked Questions & Technical Notes
