ICD-10 Code H05.22 – Edema of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.22 – Edema of orbit
What it is
H05.22 identifies swelling of the orbital tissues around the eye. It describes edema in the eye socket, not a primary disease cause.
Clinical signs
Typical findings include periorbital fullness, eye protrusion, discomfort, or pressure behind the eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents edema of the orbit or orbital swelling as the diagnosed condition. It may be appropriate when imaging or examination notes orbital tissue swelling without a more specific cause.
If the record identifies an underlying disorder, you should code that condition instead or in addition, as directed by documentation. Check documentation when the cause is unclear.
Do not use for
Do not use this code for generalized facial swelling, eyelid edema, or conjunctival swelling. Those findings are coded elsewhere if documented separately.
Coding tip
Assign H05.22 only when the provider specifically documents orbital edema or swelling of the orbit.
