ICD-10 Code H05.8 – Other disorders of orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.8 – Other disorders of orbit
What it is
H05.8 is used for orbital disorders that do not fit a more specific ICD-10-CM category. It covers miscellaneous conditions affecting the orbit, the bony cavity that holds the eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include orbital pain, swelling, protrusion, restricted eye movement, or other abnormal orbital signs noted on exam or imaging.
When to use this code
Use H05.8 when the record clearly states an orbital disorder but does not identify a more specific diagnosis. It is appropriate when the provider documents an unusual or nonspecific orbital condition and no other H05 code applies.
If the note names the exact disorder, code that specific diagnosis instead. Check documentation for laterality, cause, and any associated eye or systemic condition that may require additional coding.
Do not use for
Do not use H05.8 for trauma, infection, neoplasm, or a specific orbital diagnosis with its own code. If the condition is better described elsewhere, choose the more precise code.
Coding tip
Before assigning H05.8, confirm that the provider has documented an orbital disorder and that no more specific code is available.
