ICD-10 Code H59.323 – Postprocedural hemorrhage of eye and adnexa following other procedure, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.323 – Postprocedural hemorrhage of eye and adnexa following other procedure, bilateral
What it is
This code identifies bleeding involving both eyes or nearby adnexal structures after a procedure other than the ones specifically named elsewhere in the classification. It signals a postoperative complication, not the original eye condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include documented hemorrhage, blood in or around the eye, or postoperative bleeding noted by the surgeon after bilateral eye or adnexal procedures.
When to use this code
Use H59.323 when the record clearly states postprocedural hemorrhage affecting both eyes or adnexa after another procedure. Code the complication when it is documented as bilateral and linked to the prior procedure, even if the exact bleeding source is not fully described. Check documentation if the procedure type is unclear.
Do not use for
Do not use this code for preexisting ocular hemorrhage, trauma-related bleeding, or unilateral postprocedural hemorrhage. Do not assign it when the chart does not support bilateral involvement or a postoperative cause.
Coding tip
Confirm both laterality and the causal procedure in the operative or postoperative note before assigning H59.323.
