H35.149 ICD-10-CM Code: Retinopathy of prematurity, stage 3, unspecified eye

H35.149 is the ICD-10-CM diagnosis code for retinopathy of prematurity, stage 3, unspecified eye. This is a condition affecting the blood vessels in the retina (back of the eye) of premature infants, where abnormal blood vessel growth has progressed to stage 3, the most advanced stage before potential vision loss. The specific eye affected is not documented in the medical record. H35.149 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).

H35.149 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

When the eye laterality is known (right, left, or bilateral), use the more specific codes H35.141, H35.142, or H35.143 instead of the unspecified code H35.149.
