Paratyphoid fever, unspecified

This code describes paratyphoid fever, a systemic bacterial infection caused by Salmonella Paratyphi serovars A, B, or C. It presents with symptoms similar to typhoid fever but is generally milder, characterized by fever, headache, malaise, and sometimes gastrointestinal symptoms.

Use this code for documented cases of paratyphoid fever where the specific serovar is not identified or specified in the medical record. Documentation should clearly indicate a diagnosis of paratyphoid fever, often confirmed by blood or stool cultures.

• Differentiate from typhoid fever (002.0-002.1) based on physician documentation.
• Do not use if a specific Salmonella Paratyphi serovar (e.g., A, B, or C) is identified; use the more specific codes within 002.1.
• Code any associated complications, such as intestinal perforation or hemorrhage, separately.
