ICD-10 Code H59.36 – Postprocedural seroma of eye and adnexa following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.36 – Postprocedural seroma of eye and adnexa following other procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops in the eye or adnexa after a procedure. Use it when the record clearly links the fluid collection to prior eye-related surgery or intervention.
Clinical signs
Findings may include postoperative swelling, a soft fluid-filled collection, or localized discomfort near the surgical site. Clinical features vary; refer to documentation.
When to use this code
Use H59.36 when the provider documents a postprocedural seroma involving the eye or adnexa and the note specifies a causative procedure. It is appropriate for follow-up visits when the seroma is being evaluated or monitored after surgery. Check documentation if the exact procedure is unclear.
Do not use for
Do not use this code for nonsurgical edema, infection, hematoma, or unspecified postoperative swelling without a documented seroma. Do not assign it when the fluid collection is unrelated to a procedure.
Coding tip
Confirm both the postoperative nature and the seroma diagnosis in the operative or follow-up note before assigning H59.36.
