About H35.10
H35.10 is the ICD-10-CM diagnosis code for retinopathy of prematurity, unspecified. It belongs to category H35 (other retinal disorders), 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 H35.1, choose H35.10 (unspecified) only when documentation doesn't support a more specific option: stage 0 (H35.11), stage 1 (H35.12), stage 2 (H35.13), stage 3 (H35.14), stage 4 (H35.15), stage 5 (H35.16) and Retrolental fibroplasia (H35.17).
To report this condition, pick the subcode that matches the documentation: H35.101 (right eye), H35.102 (left eye), H35.103 (bilateral) and H35.109 (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.
