ICD-10 Code H33.43 – Traction detachment of retina, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.43 – Traction detachment of retina, bilateral
What it is
This code identifies traction detachment of the retina in both eyes. It means the retina has been pulled away from its normal position by fibrous or vitreoretinal traction.
Clinical signs
Findings may include decreased vision, visual distortion, or floaters, but clinical features vary; refer to documentation. Diagnosis is usually confirmed by ophthalmic examination and retinal imaging.
When to use this code
Use H33.43 when the provider documents bilateral traction detachment of the retina. Assign it for cases where both eyes are involved and the record clearly distinguishes this from rhegmatogenous or serous detachment.
If the note only states retinal detachment without etiology or laterality, check documentation before coding. Make sure the bilateral tractional cause is explicitly supported in the chart.
Do not use for
Do not use this code for unilateral traction detachment, other retinal detachment types, or unspecified retinal detachment. Check documentation if the laterality or mechanism is unclear.
Coding tip
Confirm both tractional mechanism and bilateral laterality in the provider’s note before assigning H33.43.
