  • the $2m enrollment failure that changed how i think about integration

    March 20, 2026

    upcoming blog post

    this one’s brewing โ€” the story of how a single 834 enrollment file brought down a health plan’s member database, and what it taught me about building resilient systems.

    what you’ll learn:

    • why batch EDI processing without idempotency is a ticking time bomb
    • the 3 AM phone call that kicked off a 72-hour war room
    • how a missing segment terminator cascaded into $2M in duplicate enrollments
    • the architectural patterns we built after to make sure it never happened again

    stay tuned. this drops soon.

    the CMS Prior Authorization Rule (CMS-0057-F) is coming January 2027. most health plans aren’t ready.

    • real timelines for PARDD compliance โ€” not the vendor marketing version
    • why your current prior auth workflow is about to become a compliance liability
    • a practical architecture blueprint for making the switch

    coming soon.
