ICD-10 Code H16.019 – Central corneal ulcer, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.019 – Central corneal ulcer, unspecified eye
What it is
This code identifies a corneal ulcer located in the central cornea, with the affected eye not specified. It describes a focal loss of corneal tissue that may threaten vision if not addressed promptly.
Clinical signs
Common findings include eye pain, redness, tearing, photophobia, and decreased vision. Clinical features vary; refer to documentation for the exact eye involved and any associated corneal infiltrate or epithelial defect.
When to use this code
Use H16.019 when the record documents a central corneal ulcer but does not identify the right or left eye. This is appropriate for outpatient, emergency, or specialist notes that confirm the diagnosis without laterality. If the chart specifies a different corneal location, code more precisely.
Do not use for
Do not use this code for corneal abrasion, keratitis without ulceration, or peripheral corneal ulcer. Check documentation if the ulcer is traumatic, infectious, or laterality is stated.
Coding tip
Always verify laterality and ulcer location before assigning H16.019.
