H30.9Unspecified chorioretinal inflammation

H30.9 is the ICD-10-CM diagnosis code for unspecified 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 4 subcodes must be used instead.

Within H30, choose H30.9 (Unspecified chorioretinal inflammation) only when documentation doesn't support a more specific option: focal chorioretinal inflammation (H30.0), disseminated chorioretinal inflammation (H30.1), posterior cyclitis (H30.2) and other chorioretinal inflammations (H30.8).

To report this condition, pick the subcode that matches the documentation: H30.90 (unspecified eye), H30.91 (right eye), H30.92 (left eye) and H30.93 (bilateral).

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