ICD-10 Code H18.021 – Argentous corneal deposits, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.021 – Argentous corneal deposits, right eye
What it is
H18.021 identifies argentous corneal deposits in the right eye. It means silver-related material has been deposited in the cornea, the clear front surface of the eye.
Clinical signs
Findings may include visible corneal discoloration or deposits on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents argentous corneal deposits in the right eye. You should also use it when the provider links the corneal finding to silver deposition and clearly identifies the right eye.
Do not guess the laterality from a general eye note. If the documentation is unclear, check documentation before coding.
Do not use for
Do not use this code for corneal opacities or deposits from other causes. It is also wrong for unspecified eye or left eye findings.
Coding tip
Confirm both the deposit type and right-eye laterality in the provider note before assigning H18.021.
