About H33.30
H33.30 is the ICD-10-CM diagnosis code for unspecified retinal break. 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 H33.3, choose H33.30 (Unspecified retinal break) only when documentation doesn't support a more specific option: horseshoe tear of retina without detachment (H33.31), round hole of retina without detachment (H33.32) and multiple defects of retina without detachment (H33.33).
To report this condition, pick the subcode that matches the documentation: H33.301 (right eye), H33.302 (left eye), H33.303 (bilateral) and H33.309 (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.
