ICD-10 Code H59.21 – Accidental puncture and laceration of eye and adnexa during an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.21 – Accidental puncture and laceration of eye and adnexa during an ophthalmic procedure
What it is
This code identifies an unintended puncture or laceration involving the eye or nearby adnexa that occurs during an ophthalmic procedure. Use it for a procedure-related complication, not for the underlying eye disease.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe a recognized intraoperative injury, such as a tear, perforation, or cut to ocular tissues during surgery.
When to use this code
Use H59.21 when the record clearly states that an accidental puncture or laceration happened during an eye procedure. It fits operative, postoperative, or complication notes that link the injury to the ophthalmic procedure. Check documentation for the exact site and timing.
Do not use for
Do not use this code for planned surgical incisions, routine postoperative pain, or eye injuries unrelated to a procedure. If the record does not clearly document a procedure-related puncture or laceration, check documentation.
Coding tip
Assign the code only when the provider documents the complication as accidental and procedure-related.
