ICD-10 Code H35.41 – Lattice Degeneration of Retina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.41 – Lattice degeneration of retina
What it is
Lattice degeneration is a peripheral retinal thinning disorder with a characteristic lattice-like pattern. It is usually found on eye examination and may be present with or without symptoms.
Clinical signs
Typical findings include peripheral retinal thinning, white lines or crisscrossing vessels, and small atrophic holes. Clinical features vary; refer to documentation.
When to use this code
Use H35.41 when the provider documents lattice degeneration of the retina, whether discovered incidentally or during evaluation for flashes, floaters, or retinal surveillance. Code it when the diagnosis is confirmed in the record. If the note only mentions a retinal tear, detachment, or nonspecific peripheral retinal change, check documentation.
Do not use for
Do not use this code for retinal detachment, retinal tear, or nonspecific visual symptoms without documented lattice degeneration. Check documentation.
Coding tip
Verify that the ophthalmology note names lattice degeneration explicitly, since peripheral retinal abnormalities are often described more broadly.
