About H59.03

H59.03 is the ICD-10-CM diagnosis code for Cystoid macular edema following cataract surgery. It belongs to category H59 (intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified), block H59 (intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified) 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 H59.0 (disorders of the eye following cataract surgery), H59.03 is specifically for Cystoid macular edema following cataract surgery. Related codes cover keratopathy (bullous aphakic) following cataract surgery (H59.01), cataract (lens) fragments in eye following cataract surgery (H59.02) and other disorders of the eye following cataract surgery (H59.09).

To report this condition, pick the subcode that matches the documentation: H59.031 (right eye), H59.032 (left eye), H59.033 (bilateral) and H59.039 (unspecified eye).

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