A new and poly-hierarchical chapter division of KSH97-P's categories has been created using the category and chapter mappings and SNOMED CT's generic structure. In the new chapter division, most categories are included in their original chapters. A considerable number of concepts are included in other chapters than their original chapters. Most of these inclusions can be explained by ICD-10's design. KSH97-P's categories are also extended with attributes using the category mappings and SNOMED CT's defining attribute relationships. About three-fourths of all concepts receive an attribute of type Finding site and about half of all concepts receive an attribute of type Associated morphology. Other types of attributes are less common.It is possible to use mappings from KSH97-P to SNOMED CT and SNOMED CT's structure to enrich KSH97-P's mono-hierarchical structure with a poly-hierarchical chapter division and attributes of type Finding site and Associated morphology. The final mappings are available as additional files for this paper.There are various types of medical terminology systems to satisfy different needs. To satisfy more needs than what exist today, both Rossi Mori et al. [1] and Cimino [2] ask for an evolution of the medical terminology systems for more flexiblity.Rossi Mori et al. describe three generations of medical terminology systems [1]. The first generation comprises traditional terminology systems [1]. This generation includes controlled vocabularies, nomenclatures, taxonomies and coding systems which satisfy most needs in paper-based information systems. In this generation, systems typically consist of a list of phrases, a list of codes, a coding scheme and a hierarchy. The role of the coding scheme is to map between phrases and codes [1]. Examples of systems in the first generation are ICD-10, KSH97-P and International Classification of %U http://www.jbiomedsem.com/content/1/1/7
