ICD-10 Code A75.2 – Typhus fever due to Rickettsia typhi (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A75.2 – Typhus fever due to Rickettsia typhi
What it is
A75.2 identifies typhus fever caused by Rickettsia typhi, an infection usually linked to flea-borne exposure. Use it when documentation names murine or endemic typhus.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include acute fever, headache, rash, and systemic illness after relevant exposure history.
When to use this code
Use this code when the provider documents typhus fever due to Rickettsia typhi or murine typhus. It also fits confirmed or suspected cases tied to compatible clinical presentation and exposure history, if the record supports that organism.
Do not use for
Do not use A75.2 for other rickettsial infections, such as spotted fever group disease or epidemic typhus. If the organism is not specified, check documentation before assigning this code.
Coding tip
Code the specific organism only when the record clearly links typhus to Rickettsia typhi.
