ICD-10 Code H11.123 – Conjunctival Concretions, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.123 – Conjunctival concretions, bilateral
What it is
H11.123 identifies concretions in both conjunctivae. These are small, usually yellow-white deposits on the eye surface lining, documented as bilateral.
Clinical signs
Patients may have visible tiny nodules on the palpebral conjunctiva, sometimes with irritation or a foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use H11.123 when the record clearly states conjunctival concretions affecting both eyes. Code this when the provider documents the condition as bilateral, whether found incidentally or during evaluation of eye discomfort.
If the note identifies only one eye, use the unilateral code instead. Check documentation when the laterality is unclear or when another conjunctival disorder is the primary diagnosis.
Do not use for
Do not use this code for nonspecific conjunctival irritation, discharge, or other conjunctival lesions without documented concretions. Do not assign it if bilateral involvement is not stated.
Coding tip
Confirm laterality in the ophthalmology note before coding, because H11.123 requires bilateral documentation.
