DRG is a casemix system that groups patients with similar diseases and similar expenses into Diagnosis Related Groups. The system is developed and maintained by The Danish Health Data Authority in order to provide insight into hospital activity and manage the funding in the healthcare system at hospital level.
In the DRG system, patients with similar diseases and similar expenses are organised into groups that each has a tariff. The latest revisions have approximately a thousand groups and covers both inpatient and outpatient activity at Danish public hospitals.
