Built for teams running claims at scale

This site exists to help PBM operations teams, pharmacy benefits analysts, healthcare IT staff, and Python automation engineers automate high-volume claims adjudication workflows. It focuses on validating formulary rules, NDC/GPI mappings, and prior-authorization logic; syncing fragmented PBM portals; batch-processing NCPDP transactions; calculating rebates; tracking accruals; and maintaining compliance audit trails.

Every guide prioritizes production-ready automation, explicit error handling, HIPAA/PHI-safe patterns, and clear Python implementations over theoretical architecture. You will find deterministic state machines, idempotent batch workers, schema-validated ingestion, and auditable pricing logic — the patterns that keep real adjudication pipelines reliable under load.

The content is organized as three connected areas. Start with the architecture foundations, move into the ingestion and parsing layer, then dive into the formulary and rule-engine logic that drives copay, tier, and prior-authorization decisions.
