ICD10PCS standardization: first stable version

Last Friday we have updated ICD10PCS Vocabulary to include new relations built from ICD10PCS leaf-level concepts to SNOMED.

Changes since November release:

  1. Relations to SNOMED parents are now much cleaner
  2. Eliminated redundancy in relations to SNOMED attributes
  3. Fixed ICD10PCS redundant internal hierarchy links – now relations are built only to the next immediate hierarchical level.

Changes include hierarchical relations from ICD10PCS procedure concepts to SNOMED parents, e.g.:

2748998 Bypass Stomach to Duodenum with Nonautologous Tissue Substitute, Percutaneous Endoscopic Approach ICD10PCS Is a 4229321 Gastroduodenostomy SNOMED
2749003 Bypass Stomach to Duodenum, Percutaneous Endoscopic Approach ICD10PCS Is a 4229321 Gastroduodenostomy SNOMED
2749203 Bypass Stomach to Duodenum with Autologous Tissue Substitute, Via Natural or Artificial Opening Endoscopic ICD10PCS Is a 4229321 Gastroduodenostomy SNOMED
2749218 Bypass Stomach to Duodenum, Via Natural or Artificial Opening Endoscopic ICD10PCS Is a 4229321 Gastroduodenostomy SNOMED

All ICD10PCS concepts remain standard and still retain internal hierarchy with ICD10PCS classification concepts, even though latter are not integrated in SNOMED (yet). Relations are currently only built for ~40 000 concepts we ourselves have encountered in data, but will be extended to all leaf-level concepts next release after we streamline debugging process.

There also are attribute-value relations built following SNOMED model, which can be used for custom queries, but otherwise exist only as to keep consistency with SNOMED logic.

Please let us know if you encounter any problems with the new relationship structure.
