ICD-10 Code H18.823 – Corneal Disorder Due to Contact Lens, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.823 – Corneal disorder due to contact lens, bilateral
What it is
H18.823 identifies a corneal disorder in both eyes caused by contact lens wear. Use it when the record links the corneal problem directly to contact lenses.
Clinical signs
Findings may include corneal irritation, redness, pain, tearing, photophobia, or reduced vision. Clinical features vary; refer to documentation for the specific corneal disorder and bilateral involvement.
When to use this code
Use this code when the provider documents a bilateral corneal disorder attributed to contact lenses, such as keratitis, abrasion, or other corneal injury from lens wear. The note should clearly connect the condition to contact lens use. If laterality or the causal link is unclear, check documentation.
Do not use for
Do not use this code for non-corneal contact lens complications or for unilateral disease. If the record does not specify bilateral involvement or does not state contact lens causation, choose a different code or check documentation.
Coding tip
Confirm both laterality and the contact lens cause in the provider note before assigning H18.823.
