ICD-10 Code H05.30 – Unspecified deformity of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.30 – Unspecified deformity of orbit
What it is
H05.30 identifies a deformity of the orbit when the exact cause, side, or type is not documented. Use it for structural orbital abnormality without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible orbital asymmetry, contour change, or abnormal eye position when the orbit’s shape is altered.
When to use this code
Use this code when the record states an unspecified orbital deformity and does not identify trauma, congenital anomaly, or another defined orbital disorder. It also fits when the provider notes deformity but gives no further detail. Check documentation if a more specific orbital diagnosis is available.
Do not use for
Do not use H05.30 when the chart documents a specific orbital condition, such as fracture, mass, inflammation, or congenital abnormality. Also avoid it if laterality or etiology is clearly stated and a more precise code exists.
Coding tip
Query for the cause and laterality before assigning H05.30, because unspecified orbital deformity is often a placeholder diagnosis.
