Quick Technical Summary: Extract copays, remaining deductibles, out-of-pocket maximums, and in-network coverage terms from 271 EDI response streams. Implementation conforms to ANSI ASC X12 Standards (005010).
Specification & Structural Breakdown
The ANSI X12 271 transaction is returned by payers to deliver detailed coverage confirmation, copay amounts, coinsurance percentages, and deductible balances.
Iterates over EB (Eligibility or Benefit Information) segments mapping coverage level (Individual/Family), network indicator (In-Network/Out-of-Network), and financial amounts.
Extracts MSG message notes, DTP plan effective/termination dates, and REF group/policy numbers.
| Segment | Description | Key Elements Extracted | Usage |
|---|---|---|---|
| EB | Eligibility / Benefit Info | EB01 (1=Active, 6=Inactive), EB02 (Coverage Level), EB03 (Service Type), EB06 (Time Qualifier), EB07 (Amount), EB08 (Percent) | Core benefit values |
| DTP | Benefit Dates | DTP01 (291=Plan Begin, 292=Plan End), DTP03 (Date) | Effective coverage window |
| REF | Policy Identification | REF01 (18=Plan Number, 6P=Group), REF02 (ID) | Group and policy tracking |
| MSG | Payer Message Text | MSG01 (Freeform benefit clarification notes) | Payer guidelines |
