Rat-bite fever, unspecified
ICD-10 A24.9 is a billable code used to indicate a diagnosis of rat-bite fever, unspecified.
Rat-bite fever is a zoonotic infection caused by the bacteria Streptobacillus moniliformis or Spirillum minus, typically transmitted through bites or scratches from infected rats or contact with their secretions. The disease presents with symptoms such as fever, chills, headache, muscle pain, and rash, which can develop within a week after exposure. In some cases, complications such as endocarditis or septic arthritis may arise if left untreated. Diagnosis is primarily clinical, supported by serological tests or culture of the bacteria. The unspecified designation indicates that the specific type of rat-bite fever is not identified, which may complicate treatment and management. Public health considerations include the need for awareness of rodent control measures and the importance of educating at-risk populations about the risks associated with handling rodents or their environments. Effective prevention strategies are crucial in reducing the incidence of this disease, particularly in urban areas where rodent populations are prevalent.
Detailed patient history including exposure to rodents, clinical symptoms, and laboratory test results.
Patients presenting with fever and a history of rodent exposure.
Consideration of differential diagnoses and potential complications.
Comprehensive patient history and physical examination findings.
Patients with flu-like symptoms and recent contact with rodents.
Awareness of local rodent populations and preventive measures.
Used when bacterial culture is performed to confirm diagnosis.
Document the source of the culture and clinical indications.
Infectious disease specialists may require additional details on the patient's history.
Common symptoms include fever, chills, headache, muscle pain, and rash, which can develop within a week after exposure.
Rat-bite fever is transmitted through bites or scratches from infected rats or contact with their secretions.
Treatment typically involves antibiotics, and early intervention is crucial to prevent complications.
