ICD-10 Code H11.242 – Scarring of conjunctiva, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.242 – Scarring of conjunctiva, left eye
What it is
H11.242 identifies scar tissue affecting the conjunctiva of the left eye. It means the lining over the white of the eye has healed with fibrous change after injury, inflammation, or other prior irritation.
Clinical signs
Findings may include visible conjunctival fibrosis, adhesions, or an irregular pale area on the left eye. Clinical features vary; refer to documentation for the exact location and cause.
When to use this code
Use this code when the provider documents scarring of the conjunctiva specifically in the left eye. It is appropriate for post-inflammatory or post-traumatic conjunctival scar changes when the record identifies the left side. Check documentation if the note only says “conjunctival scar” without laterality.
Do not use for
Do not use it for corneal scarring, eyelid scarring, or unspecified conjunctival scarring. If the documentation does not confirm the left eye, choose the unspecified or other appropriate code.
Coding tip
Always verify laterality and anatomic site in the ophthalmology note before assigning H11.242.
