ICD-10 Code H35.343 – Macular cyst, hole, or pseudohole, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.343 – Macular cyst, hole, or pseudohole, bilateral
What it is
This code identifies a bilateral macular abnormality involving a cyst, true hole, or pseudohole in the central retina. Use it when documentation specifies both eyes are affected.
Clinical signs
Patients may report blurred or distorted central vision, reduced reading ability, or a central spot. Clinical features vary; refer to documentation and ophthalmic examination findings.
When to use this code
Use H35.343 when the provider documents macular cyst, macular hole, or macular pseudohole in both eyes. It is appropriate for confirmed bilateral findings on exam or imaging. Do not infer bilaterality from a single-eye note.
Do not use for
Do not use this code for unilateral macular disease or for nonspecific retinal complaints without a documented diagnosis. Check documentation if the record only mentions epiretinal membrane or another macular disorder.
Coding tip
Confirm that the diagnosis is explicitly bilateral before assigning H35.343.
