ICD-10 Code H33.302 – Unspecified retinal break, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.302 – Unspecified retinal break, left eye
What it is
This code identifies a retinal break, such as a tear or hole, in the left eye when the type is not specified. It tells you the defect is present but the documentation does not define the exact retinal lesion.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include flashes, floaters, or a peripheral retinal defect seen on eye examination, but the record must support a left-eye retinal break.
When to use this code
Use H33.302 when the provider documents an unspecified retinal break in the left eye and does not name the lesion as a tear, hole, or other specific type. This code is appropriate when laterality is clear but the retinal defect is not further characterized. If the note is ambiguous, check documentation before coding.
Do not use for
Do not use this code for retinal detachment without a documented break, or when the provider specifies a different retinal lesion. Do not assign it if the eye or lesion type is not supported by the record.
Coding tip
Confirm both laterality and the exact retinal finding in the ophthalmology note before selecting H33.302.
