ICD-10 Code H16.319 – Corneal abscess, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.319 – Corneal abscess, unspecified eye
What it is
H16.319 identifies a corneal abscess in an unspecified eye. It means there is a localized infectious collection in the cornea, but the record does not specify right or left eye.
Clinical signs
Typical findings include a painful, red eye with corneal opacity, ulceration, or infiltrate. Clinical features vary; refer to documentation for laterality and any associated keratitis details.
When to use this code
Use this code when the provider documents a corneal abscess and does not identify the affected eye. It is appropriate for confirmed corneal infection with abscess formation in the unspecified eye. If laterality is documented, code the more specific option instead.
Do not use for
Do not use this code for nonspecific conjunctivitis, superficial foreign body, or corneal irritation without abscess. Check documentation if the condition is described as ulcer, keratitis, or another corneal disorder.
Coding tip
Verify whether the note states right, left, or unspecified eye before assigning H16.319.
