ICD-10 Code H35.161 – Retinopathy of prematurity, stage 5, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.161 – Retinopathy of prematurity, stage 5, right eye
What it is
This code identifies advanced retinopathy of prematurity in the right eye, stage 5, meaning the retina has detached. Use it when documentation specifies stage 5 disease and laterality.
Clinical signs
Stage 5 retinopathy of prematurity is associated with total retinal detachment and severe visual impairment. Clinical features vary; refer to documentation for the recorded ophthalmic findings.
When to use this code
Use H35.161 when the provider documents retinopathy of prematurity, stage 5, in the right eye. It is appropriate for ophthalmology notes, discharge summaries, or problem lists that clearly identify the stage and eye. If laterality is not stated, check documentation.
Do not use for
Do not use this code for other stages of retinopathy of prematurity or for unspecified laterality. Do not assign it when the record only says retinopathy of prematurity without confirming stage 5.
Coding tip
Always verify both the stage and the affected eye before coding, because H35.161 is specific to stage 5 disease in the right eye.
