ICD-10 Code H05.322 – Deformity of Left Orbit Due to Bone Disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.322 – Deformity of left orbit due to bone disease
What it is
This code identifies a deformity of the left eye socket caused by an underlying bone disorder. Use it when documentation links the orbital shape change to bone disease, not to trauma or a mass.
Clinical signs
Findings may include visible asymmetry of the left orbit, altered orbital contour, or eye displacement related to bony change. Clinical features vary; refer to documentation.
When to use this code
Use H05.322 when the record states that the left orbit is deformed because of a bone disease such as a skeletal disorder affecting the orbital bones. It may be supported by imaging, specialist assessment, or a clear provider statement. Check documentation if the cause is unclear.
Do not use for
Do not use this code for orbital deformity from trauma, surgery, infection, or neoplasm unless bone disease is documented as the cause. Do not assume laterality or etiology without provider support.
Coding tip
Always confirm both laterality and the documented bone-related cause before assigning H05.322.
