ICD-10 Code H59.1 – Intraoperative hemorrhage and hematoma of eye and adnexa complicating a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.1 – Intraoperative hemorrhage and hematoma of eye and adnexa complicating a procedure
What it is
This code identifies bleeding or a hematoma involving the eye or surrounding adnexa that occurs during a procedure. Use it when the complication is documented as intraoperative and linked to the procedure.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible bleeding, blood collection, or operative notes describing hemorrhage in the eye or adnexal tissues during the procedure.
When to use this code
Use H59.1 when the surgeon documents intraoperative hemorrhage or hematoma as a complication of an eye or adnexal procedure. Code it from the operative record, especially when the event occurred during surgery and required mention in the final note. Check documentation if the timing or site is unclear.
Do not use for
Do not use this code for postoperative bleeding, unrelated traumatic eye hemorrhage, or a preexisting hematoma. If the record does not clearly link the event to the procedure, check documentation.
Coding tip
Confirm both the intraoperative timing and the anatomic site before assigning H59.1.
