About H30.2
H30.2 is the ICD-10-CM diagnosis code for posterior cyclitis. 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 (chorioretinal inflammation), H30.2 is specifically for posterior cyclitis. Related codes cover focal chorioretinal inflammation (H30.0), disseminated chorioretinal inflammation (H30.1), other chorioretinal inflammations (H30.8) and unspecified chorioretinal inflammation (H30.9).
To report this condition, pick the subcode that matches the documentation: H30.20 (unspecified eye), H30.21 (right eye), H30.22 (left eye) and H30.23 (bilateral).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
