About H33.32
H33.32 is the ICD-10-CM diagnosis code for round hole of retina without 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 H33.3, choose H33.32 (Round hole of retina without detachment) only when documentation doesn't support a more specific option: unspecified retinal break (H33.30), horseshoe tear of retina without detachment (H33.31) and multiple defects of retina without detachment (H33.33).
To report this condition, pick the subcode that matches the documentation: H33.321 (eye), H33.322 (eye), H33.323 (bilateral) and H33.329 (eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
