Hemorrhagic choroidal detachment, bilateral

This code describes a condition where blood accumulates between the choroid and the sclera in both eyes, leading to a detachment of the choroid. This hemorrhage can cause visual disturbances and is often associated with ocular surgery, trauma, or certain systemic conditions.

Use this code when documentation explicitly states a hemorrhagic choroidal detachment affecting both eyes. This diagnosis is typically supported by ophthalmoscopy, B-scan ultrasonography, or other imaging studies confirming the presence of blood in the suprachoroidal space bilaterally.

• Ensure documentation specifies "hemorrhagic" to differentiate from serous choroidal detachment.
• Verify that both eyes are affected; if only one eye is involved, use the appropriate unilateral code (H31.411 or H31.412).
• Look for underlying causes or associated conditions, such as recent ocular surgery or trauma, and code them as secondary diagnoses if applicable.
