ICD-10 Code H59.33 – Postprocedural hematoma of eye and adnexa following an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.33 – Postprocedural hematoma of eye and adnexa following an ophthalmic procedure
What it is
This code identifies a hematoma, or localized collection of blood, in the eye or surrounding adnexa that develops after an ophthalmic procedure. Use it when the postoperative bleeding complication is documented as occurring in the eye region.
Clinical signs
Findings may include swelling, bruising, pain, or visible blood collection in the operative eye area. Clinical features vary; refer to documentation for the specific postoperative complication described.
When to use this code
Use H59.33 when the provider documents a postprocedural hematoma involving the eye or adnexa after an eye procedure. It is appropriate for postoperative complications such as a hematoma noted during follow-up or after surgery. Check documentation if the record only mentions bleeding without confirming a hematoma.
Do not use for
Do not use this code for routine postoperative bruising without a documented hematoma. Do not assign it for nonprocedural eye trauma or other eye complications unless the hematoma is clearly linked to the ophthalmic procedure.
Coding tip
Link the hematoma to the ophthalmic procedure in the record before coding H59.33.
