ICD-10 Code H18.032 – Corneal deposits in metabolic disorders, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.032 – Corneal deposits in metabolic disorders, left eye
What it is
This code identifies corneal deposits linked to a metabolic disorder in the left eye. It means abnormal material has accumulated in the cornea, and you should code the laterality exactly as documented.
Clinical signs
Findings may include visible corneal opacities or deposits on eye examination. Clinical features vary; refer to documentation for the specific metabolic condition and whether the left cornea is affected.
When to use this code
Use H18.032 when the provider documents corneal deposits caused by a metabolic disorder and specifies the left eye. This is appropriate for ophthalmology notes, consults, or problem lists that clearly link the corneal finding to a metabolic cause.
Assign it when the diagnosis is not just a nonspecific corneal opacity or a bilateral finding. If the record does not clearly state metabolic etiology or laterality, check documentation before coding.
Do not use for
Do not use this code for corneal deposits without a documented metabolic disorder, or when the right eye, both eyes, or unspecified eye is recorded instead. Check documentation if the cause is unclear.
Coding tip
Match both the metabolic cause and left-eye laterality in the note before assigning H18.032.
