In mid-December 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: 11 new diagnosis codes, 27 new procedure codes, and eight additional codes (Tillægskoder) were added. The newly added procedure codes mainly concern the obstetrics and gynecology, surgical procedures, endocrine, gastrointestinal, and radiology fields, and some other technology groups.
