ICD-10 Code H35.413 – Lattice Degeneration of Retina, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.413 – Lattice degeneration of retina, bilateral
What it is
H35.413 identifies lattice degeneration affecting both retinas. It describes a peripheral retinal thinning pattern that can be seen on eye examination and may be noted as an incidental finding.
Clinical signs
Findings usually include bilateral lattice-like retinal thinning, often in the peripheral retina. Clinical features vary; refer to documentation for associated holes, tears, or vitreoretinal traction.
When to use this code
Use this code when the provider documents lattice degeneration in both eyes, whether found during routine retinal evaluation or workup for symptoms. It is appropriate when the record clearly states bilateral involvement. If laterality is unclear, check documentation before coding.
Do not use for
Do not use H35.413 for unilateral lattice degeneration or for nonspecific retinal degeneration without bilateral documentation. Do not assign it for retinal detachment, tear, or hole unless those conditions are separately documented.
Coding tip
Confirm both eye laterality and the exact retinal diagnosis in the note before assigning H35.413.
