ICD-10 Code H33.013 – Retinal Detachment with Single Break, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.013 – Retinal detachment with single break, bilateral
What it is
Use this code for a retinal detachment in both eyes caused by a single retinal break in each eye. The retina separates from the underlying tissue, which can threaten vision if not documented and managed promptly.
Clinical signs
Typical findings include flashes of light, new floaters, a curtain-like shadow, or reduced peripheral vision. Clinical features vary; refer to documentation, especially if the note confirms bilateral detachment with a single break.
When to use this code
Assign H33.013 when the provider documents retinal detachment in both eyes and specifies a single break as the cause. Use it for operative, ophthalmology, or consult notes that clearly identify bilateral involvement. Check documentation if the laterality or break pattern is unclear.
Do not use for
Do not use this code for unilateral retinal detachment, multiple breaks, or retinal tears without detachment. Also avoid it if the record does not confirm both eyes or the single-break detail.
Coding tip
Confirm both laterality and break type in the ophthalmology note before coding H33.013.
