About the B02 Code Range
Zoster, also called herpes zoster, belongs to a group of viral infections marked by lesions on the skin and mucous membranes.
The subdivisions distinguish nervous system involvement, eye disease, disseminated zoster, other complications, and zoster without complications. Within the nervous system branch, B02.2 groups other involvement and divides it into named postherpetic conditions, meaning conditions after herpes zoster, and other involvement. The eye disease branch, B02.3, separates named eye conditions from unspecified and other eye disease.
