ICD-10 Code H11.121 – Conjunctival concretions, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.121 – Conjunctival concretions, right eye
What it is
H11.121 identifies conjunctival concretions in the right eye. These are small, usually yellow-white deposits on the conjunctiva, the clear tissue covering the white of the eye and inner eyelids.
Clinical signs
You may see tiny, raised, firm spots on the palpebral conjunctiva. They can be asymptomatic or cause irritation, foreign-body sensation, or mild discomfort; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents conjunctival concretions specifically in the right eye. It fits charted findings from an eye exam or ophthalmology visit when the laterality is clear. If the note does not specify the eye, check documentation before coding.
Do not use for
Do not use H11.121 for conjunctival concretions in the left eye or both eyes. Also avoid it when the documentation describes another conjunctival lesion or when laterality is not confirmed.
Coding tip
Always verify laterality in the assessment, exam, or impression before assigning H11.121.
