  1. The multiple chapter division is summarised in this table. KSH97-P's original chapters are represented in the columns to the left and the complete KSH97-P in the column furthest to the right. The rows then show the proportion of categories that after the multiple chapter division appear in each chapter. For instance, 11% of categories in chapter X are assigned to chapter I.
  2. As can be seen in Table 1, not all categories are included in the multiple chapter division. One reason is that some categories and chapters are not mapped to SNOMED CT. Another reason is that SNOMED CT's structure does not include all categories in the division.
  3. The multiple chapter division does not intentionally care about the excludes remarks in ICD-10.
