837I — Institutional Claims
The 837I (Institutional) transaction is used to submit healthcare claims for facility and institutional services (hospitals, skilled nursing facilities, etc.). The parser supports 837I for inbound processing. Outbound 837I mapping follows the same pattern as 837P — implemented as a project-specific activity in the config project.
