ICD-10 Code H59.352 – Postprocedural seroma of left eye and adnexa following an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.352 – Postprocedural seroma of left eye and adnexa following an ophthalmic procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops in the left eye or surrounding adnexal tissues after an ophthalmic procedure. Use it when documentation links the fluid collection directly to the prior eye surgery.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe postoperative swelling, a fluid-filled collection, or persistent localized fullness in the left ocular or periocular area after surgery.
When to use this code
Use H59.352 when the provider documents a postprocedural seroma affecting the left eye or adnexa after an ophthalmic operation. It is appropriate when the complication is clearly attributed to the procedure and the laterality is left. If the record only mentions postoperative swelling without confirming seroma, check documentation.
Do not use for
Do not use this code for nonspecific edema, infection, hematoma, or routine postoperative discomfort without a documented seroma. Do not assign it if the fluid collection is unrelated to an ophthalmic procedure.
Coding tip
Verify both the postoperative complication and left-sided laterality in the operative or follow-up note before coding.
