ICD-10 Code H16.07 – Perforated corneal ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.07 – Perforated corneal ulcer
What it is
H16.07 identifies a corneal ulcer that has progressed to a perforation, meaning the corneal surface has broken through full thickness. Use it for a documented perforated ulcer of the cornea.
Clinical signs
Typical findings include a corneal ulcer with full-thickness defect, possible aqueous leakage, and marked ocular pain or redness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a perforated corneal ulcer, corneal perforation from ulceration, or an ulcer that has penetrated the cornea. It is appropriate when the record clearly states perforation, not just an ulcer or abrasion. Check documentation if the note is unclear.
Do not use for
Do not use it for a nonperforated corneal ulcer, corneal abrasion, or other corneal injury without ulceration. If the chart only says “corneal ulcer” and perforation is not documented, check documentation.
Coding tip
Code H16.07 only when perforation is explicitly documented; the presence of an ulcer alone is not enough.
