ICD-10 Code H16.011 – Central corneal ulcer, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.011 – Central corneal ulcer, right eye
What it is
H16.011 identifies a corneal ulcer located in the central area of the right eye. Use it when documentation clearly states a central corneal ulcer affecting the right cornea.
Clinical signs
Typical findings include a painful red eye, corneal opacity or infiltrate, tearing, light sensitivity, and reduced vision. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a central corneal ulcer in the right eye, especially in ophthalmology notes, exam findings, or discharge diagnoses. It applies when laterality and central location are both specified.
If the record only says “corneal ulcer” without eye or location, check documentation before assigning H16.011. You should code the documented site as written, not infer the right eye.
Do not use for
Do not use this code for corneal abrasion, keratitis without ulceration, or ulcers in the left eye or unspecified eye. Check documentation if the note does not confirm a central corneal ulcer.
Coding tip
Verify both laterality and the central location in the chart before coding H16.011.
