ICD-10 Code H18.022 – Argentous corneal deposits, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.022 – Argentous corneal deposits, left eye
What it is
H18.022 identifies argentous deposits in the cornea of the left eye. Use it when documentation specifically states this left-eye corneal finding.
Clinical signs
Clinical features vary; refer to documentation. Records may describe visible corneal deposits or a corneal opacity noted on eye examination.
When to use this code
Use this code when the clinician documents argentous corneal deposits limited to the left eye. It is appropriate for ophthalmology notes, problem lists, or encounter diagnoses that name the left eye specifically.
If the record mentions corneal deposits without laterality, check documentation before coding. Code the documented eye only when the source clearly supports the left-sided diagnosis.
Do not use for
Do not use this code for corneal deposits in the right eye, both eyes, or unspecified eye. Check documentation if the note describes a different corneal disorder.
Coding tip
Verify laterality in the assessment, not just the exam findings, before assigning H18.022.
