The urgency related group (URG) is derived from the urgency disposition group (UDG) which classifies patients into 12 groups based on disposition (admitted or discharged) and urgency (triage category 1-5), including a category for patients who did not wait for treatment as well as a category for patients who died.

The URG classification system segments the UDG classification system further by using 26 major diagnostic blocks.
