}Quick Summary: Parse inbound real-time and batch HIPAA 270 eligibility check requests into structured JSON payloads in under 3ms. 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 270 transaction is used by healthcare providers, EHRs, and practice management tools to query payer databases for patient insurance active status and benefit coverage.
Traverses Loop 2100A (Information Source), Loop 2100B (Information Receiver / Provider), Loop 2100C (Subscriber), and Loop 2110C (Eligibility Request).
Extracts EQ segments containing Service Type Codes (e.g. 30 = Health Benefit Plan Coverage, 1 = Medical Care, 33 = Chiropractic, 88 = Pharmacy).
| Segment | Description | Key Elements Extracted | Usage |
|---|---|---|---|
| NM1 | Information Source / Receiver / Subscriber | NM101 (PR=Payer, 1P=Provider, IL=Insured), NM109 (Member ID) | Party routing |
| DMG | Demographic Information | DMG02 (DOB: YYYYMMDD), DMG03 (Gender: M/F) | Patient verification |
| DTP | Date of Service | DTP01 (291=Plan, 472=Service), DTP03 (Date) | Coverage active check |
| EQ | Eligibility or Benefit Inquiry | EQ01 (Service Type Code: 30, 1, 88, AL) | Requested benefit categories |

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
Yes. The parser supports both single-encounter real-time 270 transactions and multi-patient batch inquiry files.
