ICD-10 Code H05.429 – Enophthalmos due to trauma or surgery, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.429 – Enophthalmos due to trauma or surgery, unspecified eye
What it is
This code identifies backward displacement of the eyeball caused by prior trauma or surgery, when the affected eye is not specified. Use it when documentation clearly links enophthalmos to an injury or operative event.
Clinical signs
Typical findings include a sunken-appearing eye, asymmetry, and reduced orbital fullness. Clinical features vary; refer to documentation for the exact eye and the documented cause.
When to use this code
Use H05.429 when the record states enophthalmos is due to trauma or a surgical procedure and does not identify the right or left eye. It also fits follow-up visits when the condition remains active and is still being assessed.
Choose this code only if the provider documents the traumatic or postoperative cause. Check documentation if the note instead describes orbital fracture, postoperative swelling, or another eye displacement diagnosis.
Do not use for
Do not use this code for enophthalmos from a congenital, age-related, or unspecified nontraumatic cause. Do not assign it when the chart names a different eye condition or provides no causal link.
Coding tip
Verify that both the cause and the unspecified eye are documented before assigning H05.429.
