ICD-10 Code H31.422 – Serous choroidal detachment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.422 – Serous choroidal detachment, left eye
What it is
H31.422 identifies a serous choroidal detachment in the left eye. This means fluid has collected in the space around the choroid, causing it to separate from the eye wall.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include decreased vision, eye discomfort, or an abnormal ocular exam showing choroidal elevation and subretinal fluid.
When to use this code
Use H31.422 when the provider documents serous choroidal detachment specifically affecting the left eye. It is appropriate when the note clearly distinguishes the left eye from the right or bilateral eyes.
Code it from the diagnosis statement or confirmed ophthalmic findings, not from suspected disease alone. Check documentation if the record describes a related postoperative or inflammatory condition without naming serous choroidal detachment.
Do not use for
Do not use this code for right-eye or bilateral choroidal detachment. Also avoid it when the chart only mentions retinal detachment, choroidal effusion, or another unspecified eye disorder.
Coding tip
Always verify laterality in the ophthalmology note before assigning H31.422.
