About B02.3

B02.3 is the ICD-10-CM diagnosis code for zoster ocular disease. 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 6 subcodes must be used instead.

Within B02 (zoster [herpes zoster]), B02.3 is specifically for zoster ocular disease. Related codes cover zoster encephalitis (B02.0), zoster meningitis (B02.1), zoster with other nervous system involvement (B02.2), 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: B02.30 (unspecified), B02.31 (conjunctivitis), B02.32 (iridocyclitis), B02.33 (keratitis), B02.34 (scleritis) and B02.39 (disease).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
