ICD-10 Code H31.409 – Unspecified choroidal detachment, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.409 – Unspecified choroidal detachment, unspecified eye
What it is
This code identifies a choroidal detachment in an eye, but the chart does not specify which eye or the underlying cause. It is used when the detachment is documented, yet details are incomplete.
Clinical signs
Clinical features vary; refer to documentation. Choroidal detachment is typically noted on eye examination or imaging as separation of the choroid from the sclera, sometimes with reduced vision or ocular discomfort.
When to use this code
Use H31.409 when the provider documents choroidal detachment and does not identify the right or left eye. It also fits when the record confirms the condition but does not state the cause or laterality. If the note specifies a different eye or a more exact diagnosis, code that instead.
Do not use for
Do not use this code when the record identifies the affected eye or another more specific choroidal disorder. Check documentation if the finding is actually a retinal, ciliary body, or postoperative complication diagnosis.
Coding tip
Capture laterality and cause from the ophthalmology note whenever possible, because “unspecified” should be reserved for incomplete documentation.
