Hello,
The Talend Data Mapper is specifically designed for this, and it comes with a predefined 835 structure and the Talend Data Mapper - X12 HIPAA Specifications contain the structure definitions that allow you to create maps that interact with the X12 4010 or 5010 HIPAA EDI transactions.
You'll want to use the tHMap component and load the 835 structure as the input structure, which you can find at:
Metadata/Hierarchical Mapper/Other Projects/X12_5010_HIPAA (Read Only/Structures/Transactions/
Here are the Data Mapper user guide and documentation, which I recommend you read before building the job. They have a section just on EDI records. Also, be sure to read the section on Loops: in my experience, this is the hardest thing to get right about EDI mapping.

Hope it helps.
