NPCR-internal code system identifying the component types used across three biopsy-results observation profiles: NPCRBiopsyResultsTargetedBiopsyObservation, NPCRBiopsyResultsSystematicBiopsyObservation, and NPCRBiopsyResultsUnclearBiopsyObservation. Unlike the Gleason score family — where three source-specific profiles share an identical 4-component structure — biopsy results metrics differ by source:

• Targeted biopsies measure: cores count, longest cancer lesion, total biopsy length of the longest-cancer biopsy (plus per-metric missing flags). 6 components total.
• Systematic biopsies measure: cores count, cores with cancer count, total biopsy length, total cancer length in mm (plus per-metric missing flags). 8 components total.
• Unclear biopsies (combined targeted + systematic where PAD does not separate) measure the same set as systematic (cores count, cores with cancer, total biopsy length, total cancer length, plus per-metric missing flags). 8 components total — structurally identical to systematic biopsy.

This shared CodeSystem provides all component codes needed across the three profiles; each profile uses the subset relevant to its source-specific metrics.

NPCR documentation gap rationale: Informationsspecifikation §7 does not provide terminology bindings for biopsy-results variables (same pattern as MR findings, Gleason score). No international code systems (LOINC, SNOMED CT) provide equivalent coverage of this NPCR-specific granularity. This NPCR-internal CodeSystem preserves documentation fidelity by mirroring NPCR Variabelbeskrivning variable structure.

Thesis Discussion note: Unlike Gleason (3 parallel source groups + 1 Summary), BiopsyResults has no equivalent 'summary' concept in NPCR — each biopsy source reports its metrics independently, with no cross-source aggregation in INCA. Therefore the BiopsyResults profiles are 3 source-specific profiles with no Summary Observation counterpart.
