How to generate x12 file by hand
<p>I work for a small healthcare company. We use a simple browser-based gui to create our healthcare claims. Recently our number of claims has grown. To make things easier, we'd like to be able to batch bill our claims now. We only do 1 type of procedure (this requirement will not change for the foreseeable future). I need to generate an 837I file for said procedure.</p>

<p>Any resources to learn about building an edi file as well as any walkthroughs about how I can do this for one procedure? I'm not looking for an already created solution. I'm also not looking to buy anything. I'm not looking to create a full x12 parsing tool. </p>

<p>We already have a solution for receiving acknowledgements and remittance advice. However, we don't have a simple way to batch upload unless we create 837 formatted files. This is only for one procedure so I'm looking to do this myself and learn as I go along. </p>
