The International Statistical Classification of Diseases and Related Health Problems (ICD) is the basis for recording medical data and statistical information necessary for the work of clinicians and health care managers. The ICD allows the global medical community to exchange data, jointly analyze and systematize various pathologies. In the Russian Federation, the tenth revision of the ICD (ICD-10) is currently in force. Only in ICD-10 skin diseases were represented as a separate class. ICD-10 was a dynamically changing document, to which individual changes were made almost every year (these changes concerned both the addition of new codes and changes and/or deletions of individual codes). The classification of diseases of the skin and subcutaneous tissue also did not stand still and was constantly improved. It was planned to completely switch to ICD-11 by 2025. However, due to the geopolitical situation, as well as the presence of fundamental disagreements on the structure and content of individual sections of the classification, a “pause” was taken until a number of controversial and fundamental issues for the country were resolved. At present, it seems relevant to refine the existing classification, which will reflect the current needs of practicing physicians and medical concepts in such a way that it is compatible with modern information technologies while maintaining a simple structure for coding data with a high degree of detail, as well as with the possibility of timely and necessary updating of information, which will allow obtain the most accurate and useful results.
