ICD-10 Code H18.82 – Corneal disorder due to contact lens (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.82 – Corneal disorder due to contact lens
What it is
H18.82 identifies a corneal problem caused by contact lens wear. Use it when the cornea is affected by the lens itself, such as irritation or injury linked to contact lens use.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include corneal irritation, redness, pain, foreign-body sensation, or blurred vision associated with contact lens wear.
When to use this code
Use H18.82 when the provider documents a corneal disorder attributed to contact lenses. It is appropriate when the note links the corneal condition directly to lens wear, fitting, or contact lens-related trauma.
Choose this code for documented corneal involvement rather than simple contact lens intolerance or routine lens fitting issues. Check documentation if the record is unclear about whether the cornea is actually affected.
Do not use for
Do not use this code for general contact lens problems without corneal involvement. If the chart only mentions eye irritation or lens discomfort, check documentation before assigning H18.82.
Coding tip
Code H18.82 only when the provider clearly connects the corneal disorder to contact lens use.
