Choroidal rupture, bilateral

This code describes a traumatic break or tear in the choroid layer of both eyes, typically resulting from blunt force trauma to the globe. The choroid is a vascular layer between the retina and the sclera, supplying blood to the outer retina. A rupture can lead to subretinal hemorrhage, scarring, and vision loss.

Use this code when documentation explicitly states choroidal rupture affecting both eyes, usually following an injury. Supporting documentation should include details of the trauma, ophthalmoscopic findings confirming the rupture in both eyes, and any associated complications.

• Ensure documentation specifies bilateral involvement; otherwise, use the appropriate unilateral code.
• Always code the underlying cause of the trauma (e.g., assault, fall, motor vehicle accident) as an external cause code.
• Distinguish from choroidal detachment (H31.4-) or choroidal hemorrhage (H31.31-), which are distinct conditions.
