Healthcare EDI & HL7 Integrations
2022
Dynamic 835/837 EDI and HL7 parsers that turn messy, multi-vendor healthcare interchange into reliable structured data.

What it did
The problem
Why it needed building
Clinical and billing systems exchange data as dense X12 EDI (835 remittance, 837 claims) and HL7 messages that vary by vendor and break rigid parsers. The work was making interchange dependable across Iguana, fax, and internal systems without hand-coding every format variant.
The approach
How it works
Built schema-driven parsers that tokenize the X12 stream, resolve segment definitions dynamically, validate loops and control numbers, and normalize everything into internal claim and remittance models — then route the results through Iguana, a fax gateway, or internal services.

- 01Segment TokenizationSplit the X12 stream into segments and elements
- 02Schema ResolutionMap segment IDs to 835/837 definitions dynamically
- 03ValidationCheck loops, required elements, and control numbers

- 05RoutingDeliver via Iguana, fax gateway, or internal systems
The trade-off
What it cost
A schema-driven parser is slower and harder to debug than a hand-written one per vendor, and it adds a schema registry to maintain. What it buys is not shipping a release every time a vendor changes a segment.
