ANSI X12 270/271 Technical Architecture FAQ
What is an ANSI X12 270/271?
The 270 is an electronic health care eligibility inquiry sent by a provider to a payer. The 271 is the official HIPAA-mandated response returned by the clearinghouse containing active benefit and coverage details.
Decoding the EB (Eligibility Benefit) Segment
The EB segment is the core payload: EB01 defines benefit type (1=Active, B=Copay, C=Deductible, A=Coinsurance, G=OOP Max), EB03 defines service type (30=General Health, 98=Professional, 1=Medical), and EB07 defines dollar amounts.
Preventing Front-End Denials
Eligibility-related payer responses may require review of enrollment dates and member information. Use 270/271 responses as evidence, then confirm coverage and payer requirements; an eligibility response does not guarantee payment.
