Medical coding manual. The official guide to the coding guidelines in Switzerland

As part of the medical statistics, all inpatient hospital stays are recorded. The survey, which is carried out in all hospitals and clinics, includes administrative data and socio-demographic characteristics of patients as well as diagnoses and treatments. To collect this information, two medical classifications are used. It is the ICD-10-GM for diagnoses and the Swiss surgical classification (CHOP) for the treatments. The coding of diagnoses and treatments is subject to precise guidelines. The Department of Medical Classifications of the Federal Statistical Office (BFS) edits, reviews and adapts these rules at most, maintains the above-mentioned classifications and supports all those involved in coding. The coding manual contains all the coding guidelines that have been published until its approval. The coding manual is the basis for coding.
