A22.0

What This Code Means

Cutaneous anthrax is a skin infection caused by the bacterium Bacillus anthracis, characterized by a painless black sore or lesion that typically appears on exposed areas of the body. It is the most common form of anthrax infection and is generally treatable with antibiotics if caught early.

Coding Tips

• •Verify documentation specifies cutaneous anthrax rather than inhalation or gastrointestinal forms, as each has a different ICD-10-CM code
• •Document the site of infection (e.g., arm, hand, face) as this may require an additional anatomical location code for specificity in some coding systems
