Paratyphoid fever C

This code identifies an infection caused by Salmonella enterica serovar Paratyphi C, a systemic illness characterized by fever, headache, abdominal pain, and potentially gastrointestinal symptoms. It is a less common form of enteric fever compared to typhoid fever or paratyphoid A and B.

Assign this code when documentation explicitly states a diagnosis of paratyphoid fever C, confirmed by laboratory identification of Salmonella Paratyphi C. This code is appropriate for both initial and subsequent encounters related to this specific infection.

• Ensure the specific serovar "C" is documented; do not use for unspecified paratyphoid fever or other serovars.
• Code any associated complications, such as intestinal perforation or hemorrhage, separately.
• Distinguish carefully from typhoid fever (A01.0) and other paratyphoid fevers (A01.1, A01.2).
