B00.5Herpesviral ocular disease

B00.5 is the ICD-10-CM diagnosis code for herpesviral ocular disease. It belongs to category B00 (herpesviral [herpes simplex] infections), 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 B00 (herpesviral [herpes simplex] infections), B00.5 is specifically for herpesviral ocular disease. Related codes cover eczema herpeticum (B00.0), herpesviral vesicular dermatitis (B00.1), herpesviral gingivostomatitis and pharyngotonsillitis (B00.2), herpesviral meningitis (B00.3), herpesviral encephalitis (B00.4), disseminated herpesviral disease (B00.7), other forms of herpesviral infections (B00.8) and herpesviral infection, unspecified (B00.9).

To report this condition, pick the subcode that matches the documentation: B00.50 (unspecified), B00.51 (iridocyclitis), B00.52 (keratitis), B00.53 (conjunctivitis) and B00.59 (eye).

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