Extension: EnLiST LoT designation extension
| Official URL: https://bih-cei.de/fhir/therapieziele-onkologie/StructureDefinition/enlist-lot | Version: 1.0.0-ballot | ||||
| Draft as of 2026-08-03 | Computable Name: EnlistLotExt | ||||
EnLiST designation of the systemic line of therapy in X.Y notation per setting axis. The line of therapy is a clinical continuum that may span multiple organisation-bound episodes; the designation exists exactly once per line — on the leading episode or, in the MII-only path, on the systemic therapy procedure. Executing segments link via the shared lineId. Recorded, not computed.
