ICD-10 Code H05.221 – Edema of right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.221 – Edema of right orbit
What it is
H05.221 identifies swelling in the right orbital tissues around the eye. Use it when the record specifically documents edema limited to the right orbit.
Clinical signs
Findings may include visible puffiness around the right eye, orbital fullness, or swelling noted on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents edema of the right orbit as the diagnosis or a confirmed finding. It may appear in notes describing unilateral orbital swelling, including postoperative or inflammatory contexts, if the right side is specified. Check documentation for laterality and whether the swelling is orbital rather than eyelid or facial.
Do not use for
Do not use it for generalized facial edema, eyelid swelling, or left-sided orbital edema. If the record does not clearly identify the right orbit, check documentation.
Coding tip
Verify laterality carefully; right orbit codes should not be assigned from nonspecific eye swelling alone.
