About B58.0

B58.0 is the ICD-10-CM diagnosis code for toxoplasma oculopathy. It belongs to category B58 (toxoplasmosis), block B50-B64 (protozoal diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within B58 (toxoplasmosis), B58.0 is specifically for toxoplasma oculopathy. Related codes cover toxoplasma hepatitis (B58.1), toxoplasma meningoencephalitis (B58.2), pulmonary toxoplasmosis (B58.3), with other organ involvement (B58.8) and unspecified (B58.9).

To report this condition, pick the subcode that matches the documentation: B58.00 (unspecified), B58.01 (chorioretinitis) and B58.09 (oculopathy).

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