Typhoid pneumonia

This code represents a severe pulmonary complication arising from an infection with Salmonella Typhi, the bacterium responsible for typhoid fever. It signifies the presence of pneumonia as a direct consequence of systemic typhoid infection, often manifesting with respiratory distress, cough, and infiltrates on chest imaging.

This code is appropriate when documentation clearly indicates pneumonia as a complication of confirmed typhoid fever. It should be used when the physician explicitly links the lung infection to the underlying Salmonella Typhi etiology. Supporting documentation would include positive blood cultures for Salmonella Typhi and clinical signs of pneumonia.

• Do not use this code for pneumonia of unknown etiology or for pneumonia secondary to other bacterial infections.
• Always sequence this code as the primary diagnosis if the typhoid pneumonia is the reason for the encounter, followed by codes for other manifestations of typhoid fever if present.
• Ensure the medical record explicitly states "typhoid pneumonia" or clearly establishes a causal link between typhoid fever and the pneumonia.
