ICD-10 Code H35.34 – Macular cyst, hole, or pseudohole (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.34 – Macular cyst, hole, or pseudohole
What it is
This code identifies a macular cyst, macular hole, or macular pseudohole affecting the central retina. Use it when the provider documents one of these macular structural abnormalities.
Clinical signs
Clinical features vary; refer to documentation. Common findings include central visual distortion, blurred central vision, or an abnormal macular appearance on ophthalmic examination or imaging.
When to use this code
Use H35.34 when the diagnosis specifically states macular cyst, hole, or pseudohole. It is appropriate for documented retinal findings involving the macula, especially when confirmed by eye exam or imaging. If the note is nonspecific, check documentation before coding.
Do not use for
Do not use this code for other retinal disorders, peripheral retinal holes, or nonspecific vision complaints without a documented macular lesion. Check documentation if the record does not clearly identify the macula.
Coding tip
Code from the provider’s exact macular diagnosis, and verify whether the finding is a cyst, hole, or pseudohole before assigning H35.34.
