ICD-10 Code H05.323 – Deformity of bilateral orbits due to bone disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.323 – Deformity of bilateral orbits due to bone disease
What it is
H05.323 identifies a structural deformity affecting both orbits, caused by an underlying bone disease. Use it when the record documents bilateral orbital shape change or distortion linked to a bony disorder.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include visible orbital asymmetry, altered eye position, or imaging evidence of bony remodeling or deformity involving both orbits.
When to use this code
Use this code when the provider states that bilateral orbital deformity is due to bone disease, such as a documented skeletal disorder affecting the orbit. It is appropriate when the diagnosis is confirmed clinically or by imaging. If the cause is not specified, check documentation before assigning the code.
Do not use for
Do not use this code for orbital deformity from trauma, tumor, or infection unless bone disease is specifically identified. Do not assign it for general eye misalignment without orbital structural deformity.
Coding tip
Link the bilateral orbital deformity to the documented bone disease in the record; if the etiology is unclear, query the provider.
