ICD-10 Code H59.359 – Postprocedural seroma of unspecified eye and adnexa following an ophthalmic procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.359 – Postprocedural seroma of unspecified eye and adnexa following an ophthalmic procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops after an ophthalmic procedure in the eye or surrounding adnexa. Use it when the record specifies the complication but not a more exact eye or adnexal site.
Clinical signs
Findings may include postoperative swelling, a fluctuant fluid collection, or delayed healing near the surgical site. Clinical features vary; refer to documentation and confirm that the provider links the seroma to the prior eye procedure.
When to use this code
Use H59.359 when documentation states a postprocedural seroma occurred after an eye-related operation and the affected eye or adnexal structure is not further specified. It is appropriate for coding a documented surgical complication, not a routine postoperative finding. If the note names a specific site, code that more precise option instead.
Do not use for
Do not use this code for nonsurgical swelling, infection, or hemorrhage after an eye procedure. Check documentation if the fluid collection is not clearly described as a seroma or if the complication is unrelated to an ophthalmic procedure.
Coding tip
Verify both the postoperative complication and the ophthalmic procedure link before assigning H59.359.
