ICD-10 Code H11.829 – Conjunctivochalasis, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.829 – Conjunctivochalasis, unspecified eye
What it is
Conjunctivochalasis means loose, redundant conjunctival tissue on the eye surface. This unspecified-eye code is used when the record identifies the condition but does not name the affected eye.
Clinical signs
Typical findings include folded or lax conjunctiva, tearing, irritation, foreign-body sensation, or intermittent discomfort. Clinical features vary; refer to documentation.
When to use this code
Use H11.829 when the clinician documents conjunctivochalasis and does not specify right, left, or bilateral eye. It also fits follow-up visits where the diagnosis is confirmed but laterality is not recorded. If the note names a specific eye, code that laterality instead.
Do not use for
Do not use this code for general conjunctivitis, conjunctival edema, or other conjunctival disorders without conjunctivochalasis. Check documentation if the eye laterality is stated elsewhere in the record.
Coding tip
Verify laterality carefully; unspecified eye codes are appropriate only when the record truly lacks right-or-left detail.
