Equatorial staphyloma, bilateral

This code describes a bulging or thinning of the sclera in the equatorial region of both eyes, which is the area around the widest circumference of the eyeball. This condition is a complication of high myopia or other degenerative eye diseases, leading to a localized ectasia of the globe. It can result in visual disturbances and increased risk of retinal detachment.

Use this code when documentation clearly indicates the presence of an equatorial staphyloma affecting both eyes. The diagnosis should be confirmed by an ophthalmologist, often through funduscopic examination or imaging studies like OCT. This code is appropriate for patients presenting with symptoms related to the staphyloma or during routine follow-up for known ocular degeneration.

• Ensure documentation specifies "equatorial" and "bilateral" to support this specific code.
• Do not confuse with other types of staphyloma (e.g., anterior, ciliary, posterior) or with simple scleral thinning without ectasia.
• Code any underlying conditions, such as high myopia (H44.2x), as a primary or secondary diagnosis, depending on the encounter's focus.
