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

U29: Emergency use of U29

The conditions within the U29 ICD-10 code group are provisionally assigned for emergency use and deal with critical health situations that have widespread impact, such as global pandemic diseases. These conditions can be caused by various pathogens, including new viruses that may not have been previously identified or classified. Transmission methods can vary depending on the specific pathogen, but common methods include direct contact, respiratory droplets, and contaminated objects or surfaces. Symptoms are often flu-like, ranging from mild, such as cough and fever, to severe, including pneumonia and in some cases, death. Disease progression is determined by various factors, such as the individual's immune response, underlying health conditions, age, and access to medical care. The conditions can impact multiple body systems and can lead to long-term health complications if not addressed promptly.
