Code Description

ICD-10 A22.0 is a billable code used to indicate a diagnosis of pulmonary anthrax.

Key Diagnostic Point:

Pulmonary anthrax is a severe infectious disease caused by the bacterium Bacillus anthracis, primarily affecting the lungs. It is classified as a zoonotic infection, meaning it can be transmitted from animals to humans. The disease typically occurs when spores of the bacterium are inhaled, leading to a rapid onset of symptoms such as fever, cough, chest pain, and severe respiratory distress. The initial symptoms may resemble those of a common cold or flu, but can quickly progress to severe pneumonia and systemic shock. Pulmonary anthrax is often associated with occupational exposure, particularly in individuals who work with animal products, such as wool or hides, or in agricultural settings where livestock may be infected. Public health considerations are critical, as anthrax can be used as a biological weapon, necessitating surveillance and preparedness measures. Vaccination is available for high-risk populations, and prompt treatment with antibiotics is essential for improving outcomes in infected individuals.
