ICD-10 Code H18.001 – Unspecified corneal deposit, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.001 – Unspecified corneal deposit, right eye
What it is
This code identifies a deposit or opacity in the cornea of the right eye when the provider does not specify the deposit type. It is used for a right-eye corneal finding, not a broader corneal disease.
Clinical signs
Findings may include a visible corneal opacity, spot, or deposit noted on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use H18.001 when the record clearly documents an unspecified corneal deposit in the right eye and no more specific diagnosis is given. Code it when the provider describes the finding but does not name the material, cause, or exact corneal disorder. Check documentation if laterality is unclear.
Do not use for
Do not use this code if the chart identifies a different corneal condition, such as ulcer, dystrophy, scar, or foreign body. Avoid it when the deposit is documented in the left eye or both eyes.
Coding tip
Confirm right-eye laterality and look for a more specific corneal diagnosis before assigning H18.001.
