ICD-10 Code H59.333 – Postprocedural hematoma of eye and adnexa following an ophthalmic procedure, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.333 – Postprocedural hematoma of eye and adnexa following an ophthalmic procedure, bilateral
What it is
This code identifies a hematoma involving both eyes or surrounding adnexal tissues after an ophthalmic procedure. Use it when documentation states the bleeding complication is postprocedural and bilateral.
Clinical signs
Findings may include swelling, bruising, pain, or visible blood collection around the operated eye structures. Clinical features vary; refer to documentation.
When to use this code
Use H59.333 when the record clearly links the hematoma to a prior eye procedure and specifies bilateral involvement. It fits postoperative complication documentation, such as surgeon notes, discharge summaries, or follow-up visits describing bilateral postprocedural hematoma.
If the provider documents only one eye, use the unilateral code instead. If the hematoma is not stated as procedure-related, check documentation before assigning this code.
Do not use for
Do not use this code for preexisting trauma-related hematoma, nonsurgical bruising, or unspecified eye bleeding. Do not assume laterality; check documentation.
Coding tip
Verify both the postoperative cause and bilateral laterality in the provider note before coding H59.333.
