ICD-10 Code A25.1 – Streptobacillosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A25.1 – Streptobacillosis
What it is
A25.1 identifies streptobacillosis, an infection caused by Streptobacillus species, most often after exposure to infected animals. Use it when the record specifically documents this diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include fever, chills, rash, and joint pain after an animal bite or scratch, especially from rodents.
When to use this code
Use A25.1 when the clinician documents streptobacillosis or streptobacillary infection. It is appropriate for confirmed cases and for encounters where the diagnosis is clearly stated in the assessment or discharge summary. If the note only mentions exposure without infection, check documentation.
Do not use for
Do not use this code for nonspecific fever, bite wounds alone, or animal exposure without a documented streptobacillosis diagnosis. If the organism or infection type is unclear, check documentation.
Coding tip
Code the infection only when streptobacillosis is explicitly named; otherwise, query the provider for clarification.
