ICD-10 Code H35.419 – Lattice Degeneration of Retina, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.419 – Lattice degeneration of retina, unspecified eye
What it is
This code identifies lattice degeneration affecting the retina, with no eye specified in the record. It describes a peripheral retinal thinning pattern that may be found on examination, often without symptoms.
Clinical signs
Findings may include peripheral retinal thinning, visible lattice-shaped lesions, and associated retinal pigment changes. Clinical features vary; refer to documentation.
When to use this code
Use H35.419 when the provider documents lattice degeneration of the retina but does not specify right or left eye. It also fits when the note confirms the condition on exam or imaging and no retinal tear or detachment is documented. Check documentation if laterality is available elsewhere in the record.
Do not use for
Do not use this code for lattice degeneration limited to a specified eye when laterality is documented. Do not use it for retinal tear, detachment, or other retinal disorders unless those conditions are separately documented.
Coding tip
Always verify laterality in the ophthalmology note before assigning the unspecified-eye code.
