ICD-10 Code H35.349 – Macular cyst, hole, or pseudohole, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.349 – Macular cyst, hole, or pseudohole, unspecified eye
What it is
This code identifies a macular cyst, hole, or pseudohole when the affected eye is not specified. It refers to a structural abnormality in the central retina that can affect central vision.
Clinical signs
Patients may report blurred or distorted central vision, and examination may show a macular defect or irregular foveal contour. Clinical features vary; refer to documentation.
When to use this code
Use H35.349 when the record documents a macular cyst, hole, or pseudohole but does not state whether it is the right or left eye. It is appropriate for confirmed retinal findings on ophthalmic examination or imaging. If the provider specifies the eye, code that laterality instead.
Do not use for
Do not use this code when the documentation identifies a different macular disorder or clearly states the right or left eye. Check documentation if the finding is described only as suspected or uncertain.
Coding tip
Always verify laterality in the ophthalmology note before assigning this unspecified-eye code.
