ICD-10 Code H59.361 – Postprocedural seroma of right eye and adnexa following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.361 – Postprocedural seroma of right eye and adnexa following other procedure
What it is
This code identifies a seroma, or fluid collection, that develops in the right eye or nearby adnexal tissues after a procedure. It describes a postoperative complication rather than the original eye condition.
Clinical signs
Clinical features vary; refer to documentation. You may see localized swelling, fluctuation, or a documented fluid collection after surgery involving the right eye or adnexa.
When to use this code
Use this code when the provider documents a postprocedural seroma affecting the right eye or adnexal structures after another procedure. It applies when the complication is specifically linked to the prior procedure and the laterality is right. Check documentation if the record does not clearly identify the site or postoperative nature.
Do not use for
Do not use this code for nonsurgical edema, infection, or a seroma not documented as postprocedural. Do not use it if the affected side is not the right eye and adnexa.
Coding tip
Confirm both the postoperative relationship and right-sided laterality in the provider note before assigning H59.361.
