Leptospirosis, unspecified
ICD-10 A27.9 is a billable code used to indicate a diagnosis of leptospirosis, unspecified.
Leptospirosis is a bacterial infection caused by spirochetes of the genus Leptospira. It is primarily a zoonotic disease, meaning it is transmitted from animals to humans. The infection can occur through direct contact with the urine of infected animals or through contaminated water, soil, or food. Common animal reservoirs include rodents, livestock, and wildlife. Symptoms of leptospirosis can range from mild flu-like symptoms to severe illness, including jaundice, renal failure, and hemorrhagic manifestations. The disease can be asymptomatic in some individuals, complicating diagnosis. The unspecified designation in this code indicates that the specific serovar or clinical manifestation is not documented, which can occur in cases where laboratory confirmation is pending or when the clinical presentation is not fully characterized. Public health considerations are significant, as outbreaks can occur in areas with poor sanitation and flooding, highlighting the need for effective surveillance and control measures.
Detailed clinical history, exposure history, and laboratory results.
Patients presenting with fever, myalgia, and history of exposure to contaminated water.
Ensure laboratory confirmation is documented to support the diagnosis.
Comprehensive patient history and symptom assessment.
Patients with flu-like symptoms returning from endemic areas.
Consider differential diagnoses and document any travel history.
Used when leptospirosis is suspected and culture confirmation is needed.
Document the reason for the culture and any relevant clinical findings.
Infectious disease specialists should ensure proper specimen handling.
Common symptoms include fever, chills, muscle aches, vomiting, jaundice, and abdominal pain. Severe cases can lead to kidney damage, liver failure, respiratory distress, and even death.
