Diagnosis Coding

Are the health care providers (hospitals and publicly/privately funded outpatient care centres) in your country obliged to use a coding system for diagnoses?

If yes,

• Did the implementation predate COVID-19, or has it only been implemented since then?
• Please describe the coding system in place (e. g, ICD, ICPC, SNOMED, CT, other or combinations).
• Please describe the usage of the data (who’s the data holder, COVID analyses, analyses in general, scientific studies regarding COVID...).
