FAQ
ICD-10-CM code A04.6 precisely identifies enteritis, which is the inflammation of the small intestine, specifically when it is caused by the bacterium Yersinia enterocolitica.
No, A04.6 is exclusively for enteritis due to Yersinia enterocolitica. Infections by Yersinia that affect other body parts or are considered extraintestinal are coded separately under A28.2 (extraintestinal yersiniosis).
Yes, in certain cases, Yersinia enterocolitica enteritis can trigger complications like postinfective and reactive arthropathies (joint inflammation). If this occurs, the arthropathy would be coded separately under M02, with A04.6 indicating the underlying infectious cause.
