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

As part of the SpiGes survey, all inpatient hospital stays are recorded. The survey, which is carried out in all hospitals and clinics, includes not only administrative data and sociodemographic characteristics of patients, but also 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 treatments. Encoding of diagnoses and treatments is subject to precise guidelines. The Department of Medical Classifications of the Federal Office of Statistics (BFS) edits, reviews and adapts these rules at best, maintains the above classifications and supports all those involved in coding. The coding manual includes all coding guidelines published until its approval. The coding manual is the basis for coding.
