ICD-10 Code H11.442 – Conjunctival Cysts, Left Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.442 – Conjunctival cysts, left eye
What it is
Code H11.442 identifies a cyst located in the conjunctiva of the left eye. Use it when the record specifically documents a conjunctival cyst on the left side.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a visible, fluid-filled conjunctival lesion, localized irritation, or a foreign-body sensation in the left eye.
When to use this code
Use this code when the provider documents a conjunctival cyst affecting the left eye, whether found on exam or listed as the final diagnosis. It is appropriate for outpatient, specialty, or problem-list documentation when laterality is clear. If the note only says “eye cyst,” check documentation.
Do not use for
Do not use H11.442 for cysts of other eye structures or for unspecified laterality. If the documentation names a different conjunctival disorder, choose the more accurate code.
Coding tip
Verify that both the conjunctival location and left-eye laterality are documented before assigning H11.442.
