In mid-September 2022, the Danish Health Data Agency (Sundhedsdatastyrelsen) published an update of the Health Care Classification System (Sundheds-væsenets Klassifikations System, SKS). The most significant changes include: four new diagnosis codes, 14 procedure codes, and 46 additional codes (Tillægskoder) were added. The newly added procedure codes mainly concern the surgical procedures field, in addition to some other technology groups.
