ICD-10 Code H18.02 – Argentous corneal deposits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.02 – Argentous corneal deposits
What it is
H18.02 identifies argentous corneal deposits, meaning silver-colored or silver-containing material deposited in the cornea. Use it when documentation specifically names this finding.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe corneal discoloration, visible deposits on exam, or an opacified corneal appearance.
When to use this code
Use this code when the provider documents argentous corneal deposits as the diagnosis or a confirmed ocular finding. It can support coding for a localized corneal deposit without broader corneal disease if that is what the record states.
If the chart only mentions a history of silver exposure or a nonspecific corneal opacity, check documentation before assigning this code. Code the documented condition, not the suspected cause.
Do not use for
Do not use it for other corneal opacities, scars, or deposits that are not described as argentous. Check documentation if the record uses a different corneal disorder name.
Coding tip
Assign H18.02 only when the provider explicitly documents argentous corneal deposits; otherwise, query for clarification.
