Paratyphoid fever B

This code represents a specific bacterial infection caused by Salmonella Paratyphi B, characterized by fever, headache, malaise, and gastrointestinal symptoms. It is a systemic illness distinct from common salmonellosis or typhoid fever.

Assign this code for confirmed cases of paratyphoid fever type B, typically diagnosed via blood, stool, or bone marrow cultures. Documentation should clearly specify the causative organism as Salmonella Paratyphi B.

• Differentiate carefully from typhoid fever (002.0) and other salmonella infections (003.xx).
• Ensure laboratory confirmation of Salmonella Paratyphi B is present in the medical record.
• Consider additional codes for specific manifestations or complications, such as enteritis or pneumonia, if documented.
