ICD-10 Code H59.362 – Postprocedural seroma of left eye and adnexa following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.362 – Postprocedural seroma of left eye and adnexa following other procedure
What it is
This code identifies a seroma, or fluid collection, that develops in the left eye or nearby adnexa after a procedure. It applies when the postoperative fluid accumulation is documented as a complication of prior eye-related care.
Clinical signs
Clinical features vary; refer to documentation. You may see localized swelling, fluid collection, or postoperative fullness in the left ocular or adnexal area after surgery or another procedure.
When to use this code
Use this code when the provider documents a postprocedural seroma affecting the left eye or adnexa and links it to a prior procedure. It is appropriate for postoperative follow-up notes, complication evaluations, or problem lists when the seroma is specifically identified. Check documentation for laterality and the exact procedure relationship.
Do not use for
Do not use this code for nonsurgical swelling, infection, hematoma, or unspecified postoperative edema. If the record does not clearly document a seroma or does not specify the left side, check documentation.
Coding tip
Confirm that the note explicitly states “seroma” and “left” before assigning H59.362.
