ICD-10 Code H31.412 – Hemorrhagic choroidal detachment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.412 – Hemorrhagic choroidal detachment, left eye
What it is
This code identifies a hemorrhagic choroidal detachment in the left eye, meaning blood has collected in the choroidal space and separated the choroid from the underlying eye wall. It is a laterality-specific ocular diagnosis.
Clinical signs
Typical findings include sudden eye pain, decreased vision, and a visible choroidal elevation on ophthalmic examination. Clinical features vary; refer to documentation and imaging or exam findings when available.
When to use this code
Use H31.412 when the provider documents a hemorrhagic choroidal detachment affecting the left eye. It is appropriate for postoperative, traumatic, or spontaneous cases only if the record clearly states the hemorrhagic choroidal detachment and laterality. Check documentation if the note says only choroidal detachment without bleeding.
Do not use for
Do not use this code for nonhemorrhagic choroidal detachment, serous retinal detachment, or unspecified laterality. If the chart does not confirm the left eye or hemorrhage, check documentation.
Coding tip
Verify both hemorrhagic status and left-eye laterality in the ophthalmology note before assigning H31.412.
