ICD-11 Field testing - Field testing of the ICD-11 beta version in hand surgery


Hand surgery practice is characterised by surgical and conservative care for patients with a broad range of single and complex hand injuries as well as hand diseases. For an adequate mapping of diagnostic information on single and (complex) multiple hand injuries and diseases, an exact, unambiguous and reliable coding using the International Classification of Diseases (ICD) provided by the World Health Organisation (WHO) is inevitable. To date, coding of complex multiple injuries with a variety of impaired anatomical structures using the ICD-10-GM (German Modification) often means a challenge to the responsible coding staff. To ensure an exact, unambiguous and reliable future coding of patient cases within the area of hand surgery, mapping of these cases is an inevitable requirement for the 11th revision of the ICD in 2018 ( Naming concrete problems and challenges when using the currently available ICD-11 beta version in the area of hand surgery as well as proposals for modification of the available codes will support the further development and finalisation of the ICD-11 Mortality and Morbidity Statistics (MMS).

The research unit at the Chair for Public Health and Health Services Research as well as the Deutsche Gesellschaft für Handchirurgie (DGH) participate in the project funded by the Federal Ministry of Health with a case-oriented validation study. In this study, 300 cases comprising epicritic information will be coded using the ICD-10-GM and the ICD-11 beta version. Mapping of these cases to ICD-10-GM and ICD-11 will be presented and completeness of the available coding in ICD-11 will be examined. Special attention will be paid to possible gaps in mapping of complex multiple injuries within the ICD-11. Additionally, the applicability of the so called “functioning properties”, categories of the International Classification of Functioning, Disability and Health (ICF) which will be included in the ICD-11, will be tested in a substudy.
