Leptospirosis
Chapter 1:Certain infectious and parasitic diseases
ICD-10 A75 is a billable code used to indicate a diagnosis of leptospirosis.
Leptospirosis is a bacterial infection caused by spirochetes of the genus Leptospira. It is primarily transmitted to humans through contact with water contaminated by the urine of infected animals, particularly rodents, livestock, and wildlife. The disease can manifest in a wide range of symptoms, from mild flu-like signs to severe illness, including jaundice, renal failure, and hemorrhagic manifestations. The incubation period typically ranges from 5 to 14 days, and early diagnosis is crucial for effective treatment. In endemic areas, leptospirosis is often associated with exposure to contaminated water during activities such as swimming, fishing, or farming. The clinical presentation may include high fever, chills, myalgia, headache, and conjunctival suffusion. Severe cases can lead to Weil's disease, characterized by liver damage, renal failure, and bleeding. Diagnosis is confirmed through serological tests or PCR. Given its zoonotic nature and potential for outbreaks, especially in tropical regions, awareness and preventive measures are essential for at-risk populations.
Detailed clinical notes on exposure history, symptom progression, and laboratory results.
Patients presenting with fever and myalgia after exposure to contaminated water.
Ensure laboratory confirmation is documented to support coding.
Thorough documentation of presenting symptoms and any potential exposure.
Patients with acute febrile illness after recent travel to endemic areas.
Rapid assessment and documentation are crucial for timely diagnosis and treatment.
When laboratory confirmation of leptospirosis is required.
Document the reason for the culture and any relevant clinical findings.
Infectious disease specialists should ensure all relevant symptoms and exposure history are documented.
Common symptoms include fever, chills, myalgia, headache, conjunctival suffusion, and in severe cases, jaundice and renal failure.
