ICD-10 Code H05.421 – Enophthalmos due to trauma or surgery, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.421 – Enophthalmos due to trauma or surgery, right eye
What it is
H05.421 identifies inward displacement of the right eye caused by prior trauma or surgery. Use it when documentation links the enophthalmos to an injury or operative history affecting the right orbit.
Clinical signs
Typical findings include a sunken appearance of the right eye and asymmetry of the orbits. Clinical features vary; refer to documentation for the confirmed cause and laterality.
When to use this code
Use this code when the provider documents right-sided enophthalmos and states it is due to trauma or surgery. It also fits follow-up visits where the condition remains present after the original event. Check documentation if the cause is unclear or not linked to the right eye.
Do not use for
Do not use H05.421 if the record does not specify trauma or surgery, or if the affected eye is not the right eye. Check documentation for other orbital disorders that may better describe the finding.
Coding tip
Capture both laterality and cause exactly as documented, because missing either detail can change the code.
