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

ICD-10 codes U00-U49 cover new diseases of uncertain cause or urgent conditions needing immediate classification, including key codes for COVID-19 and vaping-related lung disorders. This range is essential for tracking emerging health threats and complications.

This set includes U07.0, which specifically codes for vaping-related disorders such as lung injury or lipoid pneumonitis caused by e-cigarette use or dabbing. These conditions are also known as inhalation injuries or interstitial lung disorders linked to vaping. The code U07.1 is used for confirmed COVID-19 infections, capturing a wide variety of related health issues like acute respiratory distress, myocarditis, and asymptomatic SARS-CoV-2 infections. For ongoing symptoms after initial infection, U09.9 represents post COVID-19 conditions, often called post-acute COVID-19 or chronic post-COVID-19 syndrome. Including these codes allows healthcare professionals to document both immediate and long-term effects of these modern diseases reliably for clinical care and public health monitoring.
