ICD-10 Code H15.9 – Unspecified disorder of sclera (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.9 – Unspecified disorder of sclera
What it is
H15.9 identifies a disorder of the sclera, the white outer coat of the eye, when the specific condition is not documented. Use it when the record confirms a scleral problem but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include scleral redness, pain, discoloration, thinning, or visible structural change, but the exact pattern depends on the underlying disorder.
When to use this code
Use this code when the clinician documents an unspecified scleral disorder and no further detail is available. It also fits cases where the note confirms scleral involvement, but the diagnosis remains unclear after evaluation. If the record later identifies a specific scleral condition, code that diagnosis instead.
Do not use for
Do not use H15.9 for conjunctival, corneal, or other eye disorders that do not involve the sclera. Do not use it when a more specific scleral diagnosis is documented.
Coding tip
Before assigning H15.9, check whether the provider documented a named scleral condition or only a nonspecific eye finding.
