Pasteurellosis

This code represents Pasteurellosis, a bacterial infection caused by species of Pasteurella, most commonly Pasteurella multocida. It typically manifests as localized infections such as cellulitis, abscesses, or osteomyelitis, often following animal bites or scratches. Systemic infections, including bacteremia, pneumonia, and meningitis, can occur, particularly in immunocompromised individuals.

Use this code when documentation explicitly states a diagnosis of Pasteurellosis. This often arises in patients presenting with infection after exposure to animals, such as dog or cat bites. Supporting documentation should include a confirmed diagnosis through culture or clinical presentation highly suggestive of Pasteurellosis.

• Ensure the documentation specifies "Pasteurellosis" and not a general animal bite infection without a confirmed causative organism.
• Always code the external cause of injury (e.g., W53.01XA for bite by dog) in conjunction with this code when an animal bite is the etiology.
• Consider additional codes for specific manifestations, such as cellulitis (L03.-) or osteomyelitis (M86.-), if documented.
