ICD-10 Code H05.33 – Deformity of orbit due to trauma or surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.33 – Deformity of orbit due to trauma or surgery
What it is
Use this code for an acquired change in the bony orbit’s shape after injury or surgical repair. It describes orbital deformity, not the original trauma or the procedure itself.
Clinical signs
Findings may include visible asymmetry, sunken or displaced eye position, or altered orbital contour after trauma or surgery. Clinical features vary; refer to documentation.
When to use this code
Assign H05.33 when the record documents an orbital deformity caused by prior trauma or an operative procedure. Use it when the provider identifies the deformity as the current diagnosis, even if the original event is historical.
It is appropriate for follow-up visits, specialist evaluations, or imaging reports that confirm post-traumatic or postsurgical orbital shape change. Check documentation if the cause is unclear or if the deformity is congenital.
Do not use for
Do not use this code for acute orbital injury, active fracture, or nonspecific eye swelling. It is also not for congenital orbital anomalies or cosmetic concerns without documented deformity.
Coding tip
Link the deformity to trauma or surgery in the note; if the cause is not stated, check documentation before coding.
