2026 ICD-10-CM Diagnosis Code H05.423 – Enophthalmos due to trauma or surgery, bilateral
What it is
This code identifies bilateral inward displacement of the eyeballs that occurs after trauma or surgery. It is used when both eyes are affected and the cause is documented as traumatic or postoperative.
Clinical signs
Typical findings include sunken-appearing eyes, deepened upper eyelid sulcus, and a noticeable change in orbital contour. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states bilateral enophthalmos linked to an injury or a surgical procedure. It fits postoperative orbital changes, facial trauma, or other documented causes affecting both sides. Check documentation if laterality or cause is unclear.
Do not use for
Do not use it for unilateral enophthalmos or when the cause is not trauma or surgery. If the chart does not specify bilateral involvement, check documentation.
Coding tip
Confirm both laterality and etiology in the note before assigning H05.423.
