ICD-10 Code H59.342 – Postprocedural hematoma of left eye and adnexa following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.342 – Postprocedural hematoma of left eye and adnexa following other procedure
What it is
This code identifies a hematoma, or localized collection of blood, affecting the left eye and nearby adnexal tissues after a procedure. Use it when the record clearly links the bleeding complication to the prior intervention.
Clinical signs
Clinical features may include swelling, bruising, pain, or pressure around the left eye after surgery or another procedure. Clinical features vary; refer to documentation.
When to use this code
Use H59.342 when the provider documents a postprocedural hematoma involving the left eye or adnexa and names a procedure-related cause. It is appropriate for postoperative or procedure-related bleeding complications in the left periocular area. Check documentation if laterality or the causal procedure is unclear.
Do not use for
Do not use this code for spontaneous eye hemorrhage, trauma-related bruising, or hematoma not linked to a procedure. Do not assign it if the chart does not specify the left eye and adnexa.
Coding tip
Verify both laterality and the postprocedural relationship before coding, and query the provider if either element is missing.
