U00-U49: Provisional assignment of new diseases of uncertain etiology or emergency use

U37: Emergency use of U37

The U37 code group corresponds to health conditions that necessitate emergency use. These conditions typically arise suddenly and require urgent medical attention due to their potential to severely impact health or even be life-threatening. The causes for these conditions can be varied including accidents, acute illness, or sudden exacerbation of a chronic disease. Symptoms largely depend on the specific condition at hand but commonly involve a rapid onset of severe pain, difficulty breathing, loss of consciousness, or other drastic changes in health status. The progression of these conditions is often swift, requiring immediate treatment to stave off lasting damage. Multiple bodily systems can be affected depending on the precise nature of the emergency. As a temporary code, U37 is used to identify conditions for which there is an urgent need for medical intervention and it was added during public health crisis.
