The ICD10 code for Brill-Zinsser Disease is A79.1. Brill-Zinsser Disease is a late recrudescence of epidemic typhus occurring years or decades after the initial infection. It is characterized by a milder form of the disease. Unfortunately, I couldn't find the specific ICD9 code for Brill-Zinsser Disease. It is always recommended to consult a healthcare professional or refer to the latest coding guidelines for accurate and up-to-date information.
Brill-Zinsser Disease is a recurrent form of epidemic typhus caused by the reactivation of the bacteria Rickettsia prowazekii. It typically occurs years after the initial infection, which is known as epidemic typhus.
In the International Classification of Diseases, 10th Revision (ICD-10), Brill-Zinsser Disease is classified under A75.2. This code specifically represents "recurrent epidemic louse-borne typhus fever." It is important to note that Brill-Zinsser Disease is essentially a relapse of epidemic typhus and shares the same ICD-10 code.
In the previous revision, ICD-9, there was a specific code for Brill-Zinsser Disease, which was 081.2. However, in the transition to ICD-10, this specific code was no longer included. Instead, the ICD-10 code A75.2 encompasses both the initial epidemic typhus infection and its recurrent form, Brill-Zinsser Disease.
It is crucial to consult a healthcare professional or refer to the official coding guidelines for accurate and up-to-date information on medical coding.
