ICD-10 Code H59.35 – Postprocedural seroma of eye and adnexa following an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.35 – Postprocedural seroma of eye and adnexa following an ophthalmic procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops in the eye or adnexa after an ophthalmic procedure. Use it when the documentation states the seroma is a postoperative complication.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see postoperative swelling, a fluid-filled collection, or an unexpected localized mass near the surgical site.
When to use this code
Use H59.35 when the provider documents a seroma as a complication of eye surgery, such as after cataract, eyelid, or other ophthalmic procedures. The record should link the fluid collection to the prior procedure. If the note only describes routine postoperative edema or an unspecified lump, check documentation before coding.
Do not use for
Do not use this code for infection, hemorrhage, or nonprocedural swelling of the eye or adnexa. If the condition is not clearly documented as a postprocedural seroma, check documentation.
Coding tip
Code the complication only when the provider explicitly connects the seroma to the ophthalmic procedure.
