  "description": "Extension to record whether both targeted and systematic biopsies were taken but cannot be distinguished in the PAD-utlåtande (pathology report), per NPCR Variabelbeskrivning variable D_OklarBiopsi (Både riktade och systematiska biopsier har tagits men separata svar saknas i PAD-utlåtandet).\r\n\r\nSource variable: D_OklarBiopsi\r\n- Datatyp: Lista (0/1/98)\r\n- Listvärden: 0 = Nej, 1 = Ja, 98 = Uppgift saknas\r\n- Teknisk giltighetstid: 2014-01-21 -\r\n- Obligatorisk: Ja (when D_Vavn = 1)\r\n- Beteende/logik: D_Vavn = 1 → D_OklarBiopsi = synlig OCH obligatorisk\r\n\r\nPer NPCR Manual / Variabelbeskrivning Hjälptext: \"När både riktade och systematiska biopsier har tagits men inte kan särskiljas i PAD-svaret, registreras alla biopsier sammantaget under 'Både riktade och systematiska biopsier har tagits men separat svar saknas i PAD-utlåtandet'.\"\r\n\r\nValidering rules (Variabelbeskrivning Beteende/logik):\r\n- Villkor 1: When Primär and Sekundär Gleasongrad are completed for both targeted and systematic biopsies, D_OklarBiopsi defaults to Nej\r\n- Villkor 2: When only one of (targeted, systematic) is Ja and the other is Nej, D_OklarBiopsi defaults to Nej\r\n\r\nThis extension is bound to Procedure as its only context, specifically intended for use on NPCRBiopsyProcedure instances.\r\n\r\nData type: code, bound (required) to NPCRBiopsyFlagCodes ValueSet. This shared ValueSet is also used by extensions NPCR_Targeted_Biopsy and NPCR_Systematic_Biopsy.\r\n\r\nInformation model note: D_OklarBiopsi reflects a data-quality situation rather than a distinct clinical technique — it exists because pathology reports (PAD) sometimes aggregate findings without distinguishing targeted vs systematic samples. This flag governs how subsequent biopsy results variables (D_AntOklarBiop, D_OklarBiopCa, D_OklarBiopLangd, D_OklarBiopmmcancer) are populated in NPCRBiopsyResultsObservation.\r\n\r\nTerminology binding rationale: NPCR documentation does not provide an international code system binding. The extension uses the NPCRBiopsyFlag CodeSystem (0/1/98) to preserve NPCR's internal coded values.",
