ICD-10 Code H35.721 – Serous detachment of retinal pigment epithelium, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.721 – Serous detachment of retinal pigment epithelium, right eye
What it is
This code identifies a serous detachment of the retinal pigment epithelium in the right eye. It means fluid has lifted the retinal pigment epithelium away from the underlying tissue without a tear.
Clinical signs
Findings may include blurred vision, metamorphopsia, or a localized retinal elevation on eye examination. Imaging such as optical coherence tomography may show a dome-shaped pigment epithelial detachment; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents a serous detachment of the retinal pigment epithelium specifically in the right eye. It is appropriate for confirmed diagnoses in ophthalmology notes, imaging reports, or problem lists when the laterality is stated.
Assign it when the record distinguishes this condition from other retinal or macular disorders. If the documentation only says “pigment epithelial detachment” without serous type or laterality, check documentation before coding.
Do not use for
Do not use this code for retinal detachment, subretinal fluid, or unspecified pigment epithelial detachment. Do not assume the right eye if the record does not clearly identify laterality.
Coding tip
Verify both the serous nature and the right-eye laterality in the provider’s documentation before assigning H35.721.
