Madjic.Edi.Dom 2.1.2

Madjic.Edi.Dom

Strongly typed ANSI X12 5010 version HIPAA objects for parsing and generating healthcare related documents.

This project used the official ANSI X12 databases to generate the original source code. I'm opening this project up for others to use and modify as they see fit.

When reading, you would use the static methods on the Madjic.Edi.Dom.Document class to get started. The stream passed in will be parsed into the EDI structures of Envelopes, Functional Groups, and Transaction Sets.

Examples of reading an EDI document from a given file path

Visual Basic.NET Example

Imports Madjic.Edi.Dom

Async Function ReadImplementation271(ByVal path As String) As Task(Of Document)
    Dim Doc As Document

    Using stream As New IO.FileStream(path, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
        Doc = Await Document.FromStreamAsync(stream)
    End Using

   'Examine the first transaction set
    Dim RawTS = Doc.Envelopes(0).FunctionalGroups(0).Transactions(0)

    'Treat the generic transaction set as the v5010 Implementation Guide for a Benefit Eligibility Response Transaction
    Dim Imp = TryCast(RawTS, Transactions.Transaction271.Transaction271_B1.TransactionSet)

    Return Doc
End Function

C# Example

using Madjic.Edi.Dom;

public async Task<Document> ReadImplementation271(string path)
{
  Document doc;

  using stream = new IO.FileStream(path, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
  {
    doc = await Document.FromStreamAsync(stream);
  }
  
  // Examine the first transaction set
  var RawTS = Doc.Envelopes[0].FunctionalGroups[0].Transactions[0];

  // Treat the generic transaction set as the v5010 Implementation Guide for a Benefit Eligibility Response Transaction
  var Imp = RawTS as Transactions.Transaction271.Transaction271_B1.TransactionSet;
 
  return (doc);
}

When creating, you would use the static methods on the desired transaction sets in the Madjic.Edi.Dom.Factory.* namespaces. You will notice that these methods all return objects that implement the specific interface.

C# Example (TODO)

async Task CreateFile(string path)

Internally, there are single classes used for all implementations of each segment. For example, there is an internal class named REF_Obj. This class implements a large number of interfaces, one for each distinct use. The same is true for transaction sets and individual loops (in the 837 professional there are a number of 2310 loops, they are all backed by a single class definition).

Known Issues

1. Creating transaction sets is affected by the lack of I.G. work that should happen (there should be an extra initialization step that happens to set the specialized loop and segment containers). I need to add conveniences that set required fields when instantiating segments and loops.

History

V2.1.2

• This release includes a fix to make reading ST03 optional. The 835 implementation guide allows this to be inferred from the GS segment. This stops throwing an exception. Note: this relaxing of the rule is currently global. For other transaction sets, the element should be required but isn't enforced.

V2.1.0

• This release includes very basic validation when reading a transaction set. After parsing is complete, the HasReaderErrors property on the base TransactionSet object.
• Fixes an issue with writing a new document. When trying to write a document to a stream, performing the FlushAsync operation was throwing an error.

V1.0.6

• This release includes a test case for writing a file from scratch.
• A bug has been fixed for adding segments that can repeat as well as child loops that can repeat

V1.0.4, V1.0.5

• This release includes the generated XML Documentation file for all supported platforms.
• Removed debugging statements (the file readers were dumping incoming characters to the debugger output when looking for the envelope information).

V1.0.3

• This release supports interpreting the parsed transaction sets as their appropriate Implementation Guides.
• Rudimentary validation is performed at the functional group level. If a transaction set does not agree with the group code in the GS segment, it will be ignored.
• This version does not currently enforce segment and loop level validation.
• Tests have been put in place to verify the transactions can be read and interpreted correctly.

V1.0.1, V1.0.2

Do not use. These versions do not perform correctly.
