Anthrax (A22)
ICD-10 code A22 covers various forms of anthrax, a bacterial infection caused by Bacillus anthracis. These codes specify the infection's type and location, such as cutaneous, pulmonary, gastrointestinal, or septic manifestations.
This section is used to document and classify different presentations of anthrax for accurate diagnosis and treatment tracking. For example, A22.0 refers to cutaneous anthrax, also known as skin eschar or crust on the skin. A22.1 is for pulmonary anthrax, sometimes called inhalational anthrax or anthrax pneumonia. When the infection affects the intestinal tract, A22.2 applies. A22.7 identifies anthrax-related sepsis, and A22.8 includes other less common forms, such as meningitis caused by Bacillus anthracis. If the type isn’t specified, A22.9 is assigned. Using these specific ICD-10 codes for anthrax ensures clear communication of the infection's exact nature, aiding both healthcare providers and medical coders in managing care and reporting.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Anthrax
An acute infection caused by the spore-forming bacteria BACILLUS ANTHRACIS. It commonly affects hoofed animals such as sheep and goats. Infection in humans often involves the skin (cutaneous anthrax), the lungs (inhalation anthrax), or the gastrointestinal tract. Anthrax is not contagious and can be treated with antibiotics.
Anthrax Vaccines
Vaccines or candidate vaccines used to prevent ANTHRAX.
Bacillus anthracis
A species of bacteria that causes ANTHRAX in humans and animals.
