2026 ICD-10-CM Diagnosis Code H35.412 – Lattice degeneration of retina, left eye
What it is
H35.412 identifies lattice degeneration affecting the left retina. It is a peripheral retinal thinning disorder that can be found incidentally or during evaluation for retinal symptoms.
Clinical signs
Findings may include circumferential retinal thinning, white lines, pigment changes, or atrophic holes on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents lattice degeneration specifically in the left eye. It fits routine ophthalmology visits, incidental exam findings, or follow-up of a previously diagnosed retinal degeneration. Code the laterality exactly as documented.
Do not use for
Do not use it for lattice degeneration in the right eye or both eyes. Do not use it for retinal detachment, tears, or other retinal disorders unless separately documented.
Coding tip
Confirm the eye laterality in the assessment or impression before assigning H35.412.
