ICD-10 Code H05.341 – Enlargement of right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.341 – Enlargement of right orbit
What it is
H05.341 identifies an abnormal increase in the size of the right bony eye socket. Use it when documentation specifically states enlargement of the right orbit, not just eye prominence or swelling.
Clinical signs
Findings may include a visibly enlarged right orbital contour or asymmetry on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents enlargement of the right orbit as the diagnosis or a confirmed imaging finding. It may be appropriate in evaluations for facial asymmetry, orbital deformity, or follow-up of a known orbital abnormality. Code only the right-sided location when specified.
Do not use for
Do not use it for right eye swelling, proptosis, or orbital mass unless the record states orbital enlargement. If the documentation does not clearly identify the right orbit, check documentation.
Coding tip
Verify laterality and distinguish orbital enlargement from soft-tissue swelling before assigning H05.341.
