271 Health Care Eligibility/Benefit Information (003050)
This is the standard X12 003050 spec, with 5 loops and 31 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.
Use the 271 spec in your code
ediFabric .NET
Add the C# template and its common files to your project, or reference the template NuGet package, and read 271 files into TS271 objects. See ediFabric .NET.
ediFabric Native
Map version 003050 to the Native model with set_map, then parse 271 files to JSON from Python, Java, C or C#. See Convert between EDI and JSON.
OpenEDI
Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.
Generate 271 classes in Python, Java, Node.js, Go, Rust or C
ediFabric Native returns each 271 as JSON, with the property names of the OpenEDI schema. To work with that JSON as typed objects, generate classes from the OpenEDI file in your language and deserialize the JSON into TS271. Serialize the objects back to JSON to build EDI with ediFabric Native. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats, so validate files with ediFabric Native. Read more in Generate a class from OpenEDI.
