Scleral ectasia, unspecified eye

This code describes a localized bulging or thinning of the sclera, the white outer layer of the eye, which is not further specified as to its exact type or cause. Scleral ectasia can lead to vision disturbances or other ocular complications due to the altered structural integrity of the globe.

Use this code when documentation clearly indicates scleral ectasia without specifying the laterality (right, left, or bilateral) or the specific type of ectasia (e.g., staphyloma). This code is appropriate when the physician's diagnosis is simply "scleral ectasia" and no further details are provided.

• Avoid using this code if the medical record specifies the affected eye (right, left, or bilateral); instead, use a more specific code from the H15.84- series.
• Ensure the documentation supports the diagnosis of ectasia and not just general scleral thinning or inflammation.
• Consider co-occurring conditions like high myopia or inflammatory diseases that can predispose to scleral ectasia, and code them separately if documented.
