ICD-10 Code H11.12 – Conjunctival Concretions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.12 – Conjunctival concretions
What it is
H11.12 identifies conjunctival concretions, which are small, yellow-white deposits in the conjunctiva. They are usually benign and may be found incidentally during an eye exam.
Clinical signs
Patients may have no symptoms, or they may report foreign-body sensation, irritation, or tearing. On exam, you may see tiny, firm, discrete nodules in the palpebral conjunctiva.
When to use this code
Use this code when the provider documents conjunctival concretions as the diagnosis, whether symptomatic or incidental. It is appropriate when the note clearly identifies concretions rather than another conjunctival lesion. Check documentation if the record only mentions irritation or a nonspecific conjunctival finding.
Do not use for
Do not use this code for foreign bodies, conjunctivitis, or other conjunctival masses unless concretions are specifically documented. If the diagnosis is uncertain, check documentation.
Coding tip
Code H11.12 only when the chart names conjunctival concretions; avoid assigning it from symptoms alone.
