What is ICD-11 and how does it improve on ICD-10?

ICD-11 is the latest International Classification of Diseases, endorsed by the WHO in 2019. Key improvements include post-coordination (combining codes for greater specificity), a digital-native design with RESTful API access, formal alignment with SNOMED CT through mapping, improved representation of rare diseases, and chapters covering traditional medicine, patient safety, and antimicrobial resistance.
