Bubonic plague

This code represents bubonic plague, a severe infectious disease caused by the bacterium Yersinia pestis. It is characterized by painful, swollen lymph nodes (buboes), fever, chills, and prostration, typically transmitted through flea bites from infected rodents.

Assign this code for confirmed cases of bubonic plague based on microbiological testing or strong epidemiological and clinical evidence. Documentation should clearly describe the characteristic buboes, systemic symptoms, and potential exposure history.

• Do not use this code for other forms of plague (e.g., pneumonic, septicemic); specific codes exist for those manifestations.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Ensure documentation specifies the site of the bubo if known, though this code does not require it.
