Chapter 5: Endocrine, Nutritional or Metabolic Diseases
ICD-11 to ICD-10 crosswalk mappings for codes 5A00-5D46
216 ICD-11 codes in this chapter have ICD-10 crosswalk mappings from the WHO.
Includes diabetes mellitus (type 1, type 2), thyroid disorders, obesity, malnutrition, and metabolic conditions. ICD-11 provides improved diabetes classification with better specificity for complications and introduces updated metabolic disorder categories.
