ICD-10 Code H05.339 – Deformity of unspecified orbit due to trauma or surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.339 – Deformity of unspecified orbit due to trauma or surgery
What it is
This code identifies an acquired deformity of the orbit, the bony eye socket, caused by prior trauma or surgery when the side is not specified. Use it when documentation confirms orbital shape change but does not name the right or left orbit.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible orbital contour change, asymmetry, or altered eye position after injury or an operative procedure.
When to use this code
Use H05.339 when the record states orbital deformity due to trauma or surgery and laterality is not documented. It also fits follow-up visits for a residual orbital defect from a prior fracture repair or reconstructive procedure. If the note specifies the side, use the more specific code.
Do not use for
Do not use this code for congenital orbital anomalies or deformities from tumors, infection, or inflammatory disease. Check documentation if the deformity is not clearly linked to trauma or surgery.
Coding tip
Code laterality whenever documented; unspecified orbit codes are appropriate only when the record truly lacks side information.
