About H30.0

H30.0 is the ICD-10-CM diagnosis code for focal chorioretinal inflammation. It belongs to category H30 (chorioretinal inflammation), block H30-H36 (disorders of choroid and retina) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within H30 (chorioretinal inflammation), H30.0 is specifically for focal chorioretinal inflammation. Related codes cover disseminated chorioretinal inflammation (H30.1), posterior cyclitis (H30.2), other chorioretinal inflammations (H30.8) and unspecified chorioretinal inflammation (H30.9).

To report this condition, pick the subcode that matches the documentation: H30.00 (inflammation), H30.01 (juxtapapillary), H30.02 (of posterior pole), H30.03 (peripheral) and H30.04 (macular or paramacular).

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