About H30

H30 is the ICD-10-CM diagnosis code for chorioretinal inflammation. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: H30.0 (inflammation), H30.1 (inflammation), H30.2 (cyclitis), H30.8 (inflammations) and H30.9 (inflammation).

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