What This Code Means
H35.161 is the ICD-10-CM diagnosis code for retinopathy of prematurity, stage 5, right eye. The most severe stage of retinopathy of prematurity affecting the right eye, where the retina has completely detached from the back of the eye, typically resulting in permanent vision loss. H35.161 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).
H35.161 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.
Stage 5 ROP represents total retinal detachment and is the most advanced stage; document carefully.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H35.161 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Stage 5 ROP represents total retinal detachment and is the most advanced stage; document carefully
- •Confirm right eye involvement is explicitly stated in the clinical documentation
