ICD-10 Code H59.12 – Intraoperative hemorrhage and hematoma of eye and adnexa complicating other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.12 – Intraoperative hemorrhage and hematoma of eye and adnexa complicating other procedure
What it is
This code identifies bleeding or a blood collection in the eye or nearby adnexal tissues that occurs during another procedure. Use it when the complication is clearly documented as intraoperative and involves the eye or adnexa.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visible bleeding, hematoma formation, or an operative note describing hemorrhage affecting ocular or periocular structures during surgery.
When to use this code
Use H59.12 when the surgeon documents intraoperative hemorrhage or hematoma as a complication of a procedure involving the eye or adnexa. It applies when the event is not part of the expected procedure and is specifically linked to the operation. Check documentation for laterality, if recorded.
Do not use for
Do not use this code for postoperative bleeding, traumatic eye hemorrhage, or routine blood loss not tied to an eye or adnexal procedure. If the note does not clearly state an intraoperative complication, check documentation.
Coding tip
Code the complication only when the provider links it to the procedure and documents the eye or adnexa as the site.
