ICD-10 Code H15.849 – Scleral ectasia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.849 – Scleral ectasia, unspecified eye
What it is
This code identifies thinning and outward bulging of the sclera in an unspecified eye. Use it when the record documents scleral ectasia but does not specify laterality or a more detailed cause.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible scleral thinning, focal bulging, or abnormal contour noted on eye examination.
When to use this code
Use H15.849 when the provider documents scleral ectasia and the affected eye is not specified. It also fits when the note confirms the diagnosis but lacks enough detail for a more specific code. Check documentation if the condition is linked to trauma, surgery, or another eye disorder.
Do not use for
Do not use this code for corneal disorders, generalized scleral inflammation, or other eye conditions without ectasia. If the chart names a different scleral lesion or laterality is documented elsewhere, code that instead.
Coding tip
Assign this code only when the diagnosis is explicitly stated and no better eye-specific detail is available.
