ICD-10 Code H11.1 – Conjunctival degenerations and deposits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.1 – Conjunctival degenerations and deposits
What it is
H11.1 identifies degenerative or deposit-related changes of the conjunctiva, the thin membrane covering the white of the eye and inner eyelids. Use it when the record describes conjunctival degeneration, deposits, or both.
Clinical signs
Findings may include visible conjunctival plaques, deposits, or localized thickening on eye exam. Clinical features vary; refer to documentation for the exact lesion type and laterality, if stated.
When to use this code
Use H11.1 when the clinician documents a conjunctival degeneration or deposit as the diagnosis, such as a chronic surface change noted on ophthalmic examination. Code it when the condition is the reason for the visit or is clinically relevant to care. If the note only describes a nonspecific eye irritation, check documentation before assigning this code.
Do not use for
Do not use this code for corneal, scleral, or eyelid lesions. Also avoid it when the record documents a different conjunctival disorder, such as inflammation or acute infection.
Coding tip
Confirm the provider specifically names a conjunctival degeneration or deposit before coding H11.1.
