About H33.2

H33.2 is the ICD-10-CM diagnosis code for serous retinal detachment. It belongs to category H33 (retinal detachments and breaks), 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 H33 (retinal detachments and breaks), H33.2 is specifically for serous retinal detachment. Related codes cover retinal detachment with retinal break (H33.0), retinoschisis and retinal cysts (H33.1), retinal breaks without detachment (H33.3), traction detachment of retina (H33.4) and other retinal detachments (H33.8).

To report this condition, pick the subcode that matches the documentation: H33.20 (unspecified eye), H33.21 (right eye), H33.22 (left eye) and H33.23 (bilateral).

Don't report H33.2 together with the conditions in its Excludes1 note: central serous chorioretinopathy (H35.71-).

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