About B02.2
B02.2 is the ICD-10-CM diagnosis code for zoster with other nervous system involvement. It belongs to category B02 (zoster [herpes zoster]), block B00-B09 (viral infections characterized by skin and mucous membrane lesions) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.
Within B02, choose B02.2 (Zoster with other nervous system involvement) only when documentation doesn't support a more specific option: zoster encephalitis (B02.0), zoster meningitis (B02.1), zoster ocular disease (B02.3), disseminated zoster (B02.7), zoster with other complications (B02.8) and zoster without complications (B02.9).
To report this condition, pick the subcode that matches the documentation: B02.21 (ganglionitis), B02.22 (neuralgia), B02.23 (polyneuropathy), B02.24 (myelitis) and B02.29 (involvement).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
