ICD-10 Code H31.429 – Serous choroidal detachment, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.429 – Serous choroidal detachment, unspecified eye
What it is
This code identifies a serous, or fluid-related, separation of the choroid in an unspecified eye. It means the eye has a choroidal detachment, but the record does not specify laterality.
Clinical signs
Clinical features may include decreased vision, ocular discomfort, or a visible detachment on ophthalmic examination. Imaging or fundus findings may support the diagnosis; clinical features vary, so refer to documentation.
When to use this code
Use H31.429 when the clinician documents serous choroidal detachment and does not identify the right or left eye. It also fits when the note confirms a fluid-related choroidal detachment without further laterality detail. Check documentation if the record mentions trauma, surgery, or another cause, because those details may affect coding.
Do not use for
Do not use this code for choroidal detachment with specified laterality, or for retinal detachment and other posterior segment disorders. If the chart describes a different eye condition, code the documented diagnosis instead.
Coding tip
Verify laterality in the ophthalmology note before assigning this unspecified-eye code.
