ICD-10 Code H16.071 – Perforated corneal ulcer, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.071 – Perforated corneal ulcer, right eye
What it is
Use this code for a corneal ulcer in the right eye that has progressed to perforation, meaning the corneal surface has broken through. It indicates a serious, sight-threatening eye condition.
Clinical signs
Findings may include severe eye pain, redness, tearing, decreased vision, and visible corneal defect. Clinical features vary; refer to documentation for confirmation of perforation and right-eye laterality.
When to use this code
Assign H16.071 when the provider documents a perforated corneal ulcer affecting the right eye. Use it for confirmed cases in which the record clearly identifies corneal ulceration with perforation, not just a nonperforated ulcer or corneal abrasion.
If the note describes laterality, code the right eye specifically. Check documentation when the chart mentions corneal ulcer, corneal melt, or corneal perforation without a clear diagnosis statement.
Do not use for
Do not use this code for corneal ulcer of the left eye, bilateral disease, or an ulcer without perforation. Do not use it for nonspecific corneal injury unless the provider documents a perforated ulcer.
Coding tip
Confirm both perforation and right-eye laterality in the provider note before assigning H16.071.
