ICD-10 Code H11.129 – Conjunctival Concretions, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.129 – Conjunctival concretions, unspecified eye
What it is
This code identifies conjunctival concretions in an unspecified eye. These are tiny, usually yellow-white deposits in the conjunctiva, the clear tissue covering the white of the eye and inner eyelids.
Clinical signs
Patients may have no symptoms, or they may report irritation, foreign-body sensation, or mild discomfort. Clinical features vary; refer to documentation.
When to use this code
Use H11.129 when the record documents conjunctival concretions but does not specify right or left eye. It is appropriate when the provider notes the finding on exam and does not describe another conjunctival disorder as the primary diagnosis. If the eye is specified, use the laterality-specific code instead.
Do not use for
Do not use this code for conjunctival lesions that are not concretions or for unrelated corneal, eyelid, or lacrimal conditions. Check documentation if the note only mentions eye irritation without confirming concretions.
Coding tip
Always verify laterality in the chart before assigning the unspecified-eye code.
