ICD-10 Code H59.121 – Intraoperative hemorrhage and hematoma of right eye and adnexa complicating other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.121 – Intraoperative hemorrhage and hematoma of right eye and adnexa complicating other procedure
What it is
This code identifies bleeding or a blood collection involving the right eye or surrounding adnexa that occurs during another procedure. Use it when the operative complication is documented as intraoperative and affects the right side.
Clinical signs
Findings may include visible bleeding, hematoma formation, or unexpected blood in the operative field involving the right eye or adnexa. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states that hemorrhage or hematoma occurred during surgery or another procedure and the right eye or adnexa was involved. It applies to procedural complications, not to preexisting eye bleeding. If laterality or the intraoperative nature is unclear, check documentation.
Do not use for
Do not use this code for hemorrhage that is postoperative, traumatic, or unrelated to a procedure. Do not assign it if the documentation does not specify the right eye or adnexa.
Coding tip
Link the complication to the procedure note and confirm laterality before assigning H59.121.
