ICD-10 Code H33.052 – Total retinal detachment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.052 – Total retinal detachment, left eye
What it is
This code identifies a complete separation of the retina from the underlying tissue in the left eye. It documents the anatomic location and laterality of the detachment.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include sudden vision loss, flashes, floaters, or a curtain-like shadow affecting the left eye.
When to use this code
Use H33.052 when the provider documents total retinal detachment in the left eye. It fits ophthalmology notes, consultation reports, or imaging-based diagnoses that clearly identify complete detachment and laterality.
If the record says retinal detachment without specifying totality or eye, check documentation before assigning this code. Confirm that the condition is not described as partial, rhegmatogenous, tractional, or serous unless the note specifically supports H33.052.
Do not use for
Do not use this code for retinal detachment in the right eye, bilateral detachment, or unspecified laterality. Do not assign it when the documentation describes another retinal disorder or a partial detachment.
Coding tip
Verify both totality and left-eye laterality in the provider note before coding.
