ICD-10 Code H05.3 – Deformity of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.3 – Deformity of orbit
What it is
H05.3 identifies a deformity of the bony orbit, the eye socket. Use it when the orbit has an abnormal shape or contour documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible asymmetry of the orbit, abnormal orbital contour, or associated displacement of the eye.
When to use this code
Use H05.3 when the record clearly states deformity of the orbit, including congenital, traumatic, or acquired changes in orbital shape. You may also use it when imaging or specialist notes describe orbital deformity without a more specific diagnosis. Check documentation if the cause is unclear.
Do not use for
Do not use this code for general eye disorders, eyelid problems, or nonspecific facial deformity. If the chart identifies a fracture, mass, or other specific orbital condition, code that diagnosis instead.
Coding tip
Query for the underlying cause and any more specific orbital diagnosis before assigning H05.3.
