Verified steps
Inventory which networks a trading partner is reachable on: Carequality Interoperability Framework, eHealth Exchange, and/or a TEFCA QHIN, since major networks currently operate in parallel during the transition
Where a partner is reachable only via TEFCA, connect through a Designated QHIN (eHealth Exchange has achieved TEFCA QHIN designation) rather than assuming legacy Carequality connectivity alone suffices
Query current network directories rather than a cached participant list, since organization reachability shifts as EHR vendors migrate customers to their own QHIN infrastructure
Track which exchange purposes and query/FHIR capabilities are supported over each network path, since capabilities can differ between legacy Carequality exchange and TEFCA QHIN-to-QHIN exchange
Design for dual-stack operation (legacy network plus TEFCA) rather than a hard cutover, since no blanket sunset date for legacy Carequality/eHealth Exchange connectivity has been established
Known gotchas
Do not assume Carequality or eHealth Exchange connectivity is deprecated or being shut down -- both continue to operate and are aligning their strategy with TEFCA rather than ceasing independently; verify current status directly with the network before removing legacy integrations
TEFCA's QHIN-to-QHIN capabilities (including FHIR-based exchange) are still being phased in -- confirm which capabilities and protocol requirements currently apply with the RCE/QHIN rather than assuming full feature parity with legacy Carequality
Reachability of a specific organization is a moving target during vendor-driven migrations; re-check directories rather than relying on stale integration mappings
