The Challenge

The Transformation Gap

Payers store claims data in X12 EDI format. CMS requires FHIR APIs. The gap is the transformation layer.

Profile Mapping

Transaction to Profile Mapping

Each X12 transaction automatically maps to the correct CMS-required FHIR profile.

X12 Transaction FHIR Profile Primary Resource
837P/I/D (Claims) CARIN Blue Button 2.1.0 ExplanationOfBenefit
835 (Remittance) CARIN Blue Button 2.1.0 ExplanationOfBenefit
278 (Prior Auth) Da Vinci PAS 2.0.1 Claim, ClaimResponse
270/271 (Eligibility) US Core 6.1.0 CoverageEligibilityRequest/Response

Note: 270/271 uses US Core because Da Vinci PDex does not define eligibility profiles.

Integration

Simple Integration

Transform X12 EDI to CMS-compliant FHIR bundles with a single method call.

Basic Transformation

Program.cs 
// CMS-0057-F compliant output
var result = await Interop.X12ToFhirAsync(
    x12Message,
    OutputFormat.Cms0057F
);

if (result.Success)
{
    string fhirJson = result.FhirBundle;
    // CARIN Blue Button, Da Vinci PAS
    // PDex Provenance included
}

Batch Processing

Program.cs 
var options = new BatchOptions
{
    Domain = "CMS-0057-F",
    OutputFormat = OutputFormat.Cms0057F
};

var result = await Interop.ProcessBatchAsync(
    "./input/x12", options
);

Console.WriteLine($"Processed: {result.TotalFiles}");
