ICD-10 Code H18.023 – Argentous corneal deposits, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.023 – Argentous corneal deposits, bilateral
What it is
H18.023 identifies argentous deposits in both corneas. Use it when the record documents bilateral corneal silver-like deposits without a broader corneal disorder.
Clinical signs
Findings may include visible bilateral corneal discoloration or fine deposits on slit-lamp exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the ophthalmology note specifically states argentous corneal deposits in both eyes. It is appropriate when the provider documents the condition as the diagnosis and there is no more specific corneal code.
If the chart only mentions corneal opacity, foreign material, or another corneal disease, check documentation before assigning H18.023. Code the documented bilateral finding, not a presumed cause.
Do not use for
Do not use this code for unilateral deposits or for nonspecific corneal haze. Check documentation if the note describes a different corneal opacity or another eye disorder.
Coding tip
Confirm that both eyes are documented and that “argentous” appears in the diagnosis, not just in the exam description.
