ICD-10 Code H05.229 – Edema of unspecified orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.229 – Edema of unspecified orbit
What it is
Use this code for swelling in the orbital tissues when the specific orbit side is not documented. It indicates edema around the eye socket, not a diagnosis of the cause.
Clinical signs
Typical findings include periorbital fullness, puffiness, and possible eyelid swelling. Clinical features vary; refer to documentation for laterality, associated pain, redness, or vision changes.
When to use this code
Assign H05.229 when the provider documents orbital edema but does not identify the right or left orbit. Use it for nonspecific swelling of the orbit in the absence of a more detailed diagnosis. If the chart names a cause, code the underlying condition instead.
Do not use for
Do not use this code for eyelid edema, generalized facial swelling, or orbital swelling with documented laterality. Check documentation if the record identifies trauma, infection, or another specific orbital disorder.
Coding tip
Look for laterality and an underlying cause before assigning H05.229.
