ICD-10 Code H15.842 – Scleral ectasia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.842 – Scleral ectasia, left eye
What it is
H15.842 identifies scleral ectasia affecting the left eye. It means the sclera is abnormally thinned or stretched, creating a localized outward bulge.
Clinical signs
Findings may include visible scleral thinning, bluish discoloration, or focal protrusion of the eye wall. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents scleral ectasia specifically in the left eye. It is appropriate for confirmed structural scleral thinning or bulging on ophthalmic exam or imaging. Check documentation if the note only mentions scleral abnormality without laterality.
Do not use for
Do not use it for corneal ectasia, general scleral inflammation, or unspecified eye involvement. If the record does not clearly state left eye scleral ectasia, check documentation.
Coding tip
Confirm both the diagnosis and laterality in the ophthalmology note before assigning H15.842.
