Paratyphoid fever, unspecified

This code signifies an acute systemic infection caused by Salmonella enterica serovars Paratyphi A, B, or C, characterized by fever, headache, malaise, and gastrointestinal symptoms. It represents a diagnosis of paratyphoid fever where the specific serovar or type is not documented.

Utilize this code when a definitive diagnosis of paratyphoid fever is established, but the medical record does not specify the particular serotype (e.g., Paratyphi A, B, or C). This is appropriate when laboratory confirmation of Salmonella Paratyphi is present, but further differentiation is lacking.

• Avoid using this code if the specific serovar (e.g., Paratyphi A) is documented; instead, use the more specific code.
• Ensure documentation supports a diagnosis of paratyphoid fever, typically through positive blood or stool cultures.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter.
