ICD-10 Code H35.342 – Macular cyst, hole, or pseudohole, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.342 – Macular cyst, hole, or pseudohole, left eye
What it is
This code identifies a structural abnormality in the macula of the left eye, including a macular cyst, macular hole, or pseudohole. Use it when documentation specifies the left eye and the exact macular lesion.
Clinical signs
Patients may report blurred or distorted central vision, especially with reading or fine detail. Clinical features vary; refer to documentation and ophthalmic examination findings such as macular changes on retinal imaging.
When to use this code
Use H35.342 when the provider documents a macular cyst, hole, or pseudohole in the left eye. It is appropriate for ophthalmology notes, imaging-confirmed diagnoses, or follow-up visits for a known left macular lesion.
If the record does not clearly specify the left eye or the exact macular condition, check documentation before coding. Code the documented laterality only when it is stated.
Do not use for
Do not use this code for right-eye or bilateral macular lesions, or for nonspecific retinal disorders. Do not assign it when the note describes a different macular diagnosis; check documentation.
Coding tip
Confirm laterality and the exact term “cyst,” “hole,” or “pseudohole” in the provider record before selecting H35.342.
