ICD-10 Code H59.331 – Postprocedural hematoma of right eye and adnexa following an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.331 – Postprocedural hematoma of right eye and adnexa following an ophthalmic procedure
What it is
This code identifies a hematoma, or localized collection of blood, affecting the right eye and nearby adnexal structures after an ophthalmic procedure. Use it when the documentation links the bleeding complication directly to the procedure.
Clinical signs
Findings may include swelling, bruising, pain, or visible blood collection around the operative eye. Clinical features vary; refer to documentation for the specific postoperative presentation and laterality.
When to use this code
Use H59.331 when the provider documents a postprocedural hematoma involving the right eye or adnexa after an eye procedure. It fits postoperative complications such as a documented hematoma at the surgical site. If the record does not clearly connect the hematoma to the procedure, check documentation.
Do not use for
Do not use this code for spontaneous ocular hemorrhage, trauma-related bleeding, or hematoma in the left eye or unspecified eye. If the complication is not postprocedural, choose a different diagnosis code.
Coding tip
Verify the operative note and postoperative assessment for explicit right-sided, procedure-related hematoma documentation before assigning H59.331.
