ICD-10 Code H33.309 – Unspecified retinal break, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.309 – Unspecified retinal break, unspecified eye
What it is
This code identifies a retinal break in an eye when the chart does not specify the type of break or which eye is affected. Use it when the documentation confirms a retinal tear, hole, or break, but details are incomplete.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include flashes, floaters, or a peripheral visual field defect, and the diagnosis is usually confirmed on dilated retinal examination.
When to use this code
Use H33.309 when the provider documents an unspecified retinal break and does not identify the laterality. It also fits when the record mentions a retinal break but does not distinguish a tear, hole, or other subtype. If the note later specifies the eye or lesion type, code that more specific diagnosis instead.
Do not use for
Do not use this code for retinal detachment without a documented break, or for a clearly specified retinal tear or hole with a more exact code. Check documentation.
Coding tip
Query for laterality and break type when the note says only “retinal break,” because more specific coding may be available.
