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.

Use this code when documentation clearly indicates a diagnosis of bubonic plague, often confirmed by laboratory identification of Yersinia pestis from bubo aspirates, blood, or other body fluids. This code is appropriate for initial encounters and subsequent care related to this specific form of plague.

• Distinguish from other forms of plague, such as pneumonic or septicemic, which have different ICD-10-CM codes.
• Ensure documentation specifies "bubonic" plague; if not specified, query the provider for clarification.
• Consider additional codes for associated complications or manifestations, such as sepsis (A40.-, R65.20, R65.21) if present.
