ICD-10 Code H31.40 – Unspecified choroidal detachment (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.40 – Unspecified choroidal detachment
What it is
H31.40 identifies a choroidal detachment without further detail. Use it when the chart documents separation of the choroid, but does not specify the cause, laterality, or type.
Clinical signs
Clinical features vary; refer to documentation. Findings may include decreased vision, ocular pain, shallow anterior chamber, or a visible detachment on eye examination or imaging.
When to use this code
Use this code when the provider documents choroidal detachment and does not state a more specific type or cause. It also fits cases where laterality is not recorded. If the note gives more detail, code to that specificity instead.
Do not use for
Do not use H31.40 when the record identifies a specific choroidal detachment cause or laterality. Check documentation if the condition is actually retinal detachment, serous effusion, or another posterior segment disorder.
Coding tip
Before assigning H31.40, look for laterality and any documented underlying cause to see whether a more specific code is available.
