ICD-10 Code H59.349 – Postprocedural hematoma of unspecified eye and adnexa following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.349 – Postprocedural hematoma of unspecified eye and adnexa following other procedure
What it is
This code identifies a hematoma in the eye or nearby adnexa that develops after a procedure. Use it when the record documents a postprocedural collection of blood, but the exact eye structure is not further specified.
Clinical signs
Findings may include localized swelling, bruising, pain, or visible blood collection after an eye-related procedure. Clinical features vary; refer to documentation.
When to use this code
Use H59.349 when the provider documents a hematoma as a complication after an eye or adnexal procedure and does not name a more specific site. It is appropriate for postoperative bleeding collections noted in follow-up, consult, or complication documentation. Check documentation if the record only mentions hemorrhage without hematoma.
Do not use for
Do not use this code for preexisting orbital or eyelid hematomas unrelated to a procedure. Do not use it when the complication is better described by a more specific eye or adnexal code.
Coding tip
Link the code to the documented procedure complication and confirm that “hematoma” is explicitly stated.
