ICD-10 Code H05.89 – Other disorders of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.89 – Other disorders of orbit
What it is
H05.89 identifies other specified disorders affecting the orbit, the bony socket that contains the eye. Use it when the orbital condition is documented but does not fit a more specific orbit code.
Clinical signs
Clinical features vary; refer to documentation. Common orbital findings may include swelling, pain, protrusion, restricted eye movement, or visible mass effect, depending on the underlying disorder.
When to use this code
Use this code when the provider documents an orbital disorder that is not otherwise classified and no more specific code applies. It may support coding for atypical, residual, or unspecified orbital conditions after review of the record.
Confirm that the diagnosis is in the orbit and not the eyelid, globe, or lacrimal structures. If the note names a more specific orbital disease, choose that code instead.
Do not use for
Do not use for eyelid, eye globe, lacrimal, or optic nerve disorders. Also avoid this code when documentation supports a more specific orbital diagnosis.
Coding tip
Check the provider’s exact wording for location and specificity before assigning H05.89.
