ICD-10 Code H16.072 – Perforated corneal ulcer, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.072 – Perforated corneal ulcer, left eye
What it is
This code identifies a corneal ulcer in the left eye that has progressed to perforation. It indicates a full-thickness corneal defect and is a serious eye condition requiring precise documentation.
Clinical signs
Findings may include a visible corneal ulcer, severe pain, redness, tearing, photophobia, and decreased vision. Clinical features vary; refer to documentation for confirmation of perforation and left-eye involvement.
When to use this code
Use H16.072 when the record clearly states a perforated corneal ulcer affecting the left eye. Apply it when the provider documents corneal perforation from an ulcer, not just corneal erosion or nonperforated ulceration. If laterality is unclear, check documentation.
Do not use for
Do not use this code for a corneal ulcer without perforation or for ulcers in the right eye or unspecified eye. Check documentation if the note describes another corneal disorder instead.
Coding tip
Confirm both perforation and left-eye laterality in the provider note before assigning H16.072.
