ICD-10 Code H33.22 – Serous retinal detachment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.22 – Serous retinal detachment, left eye
What it is
H33.22 identifies a serous retinal detachment affecting the left eye. This means fluid has collected under the retina and separated it from the underlying tissue, without a tear being the primary cause.
Clinical signs
Common findings include blurred or distorted vision, decreased visual acuity, or a visible detachment on ophthalmic examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents serous retinal detachment in the left eye and the record supports that laterality. It is appropriate for confirmed detachments described as exudative or serous, including cases noted on retinal exam or imaging. Check documentation if the cause is not clearly stated.
Do not use for
Do not use H33.22 for retinal detachment with a tear, tractional detachment, or unspecified retinal detachment. Also avoid it if the documentation does not clearly identify the left eye.
Coding tip
Verify both laterality and the detachment type before assigning H33.22.
