ICD-10 Code H05.10 – Unspecified Chronic Inflammatory Disorders of Orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.10 – Unspecified chronic inflammatory disorders of orbit
What it is
H05.10 identifies chronic inflammation in the orbit, the tissue surrounding the eye, when the specific cause or subtype is not documented. Use it when the record confirms an ongoing inflammatory orbital disorder but does not name a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include orbital pain, swelling, redness, or eye movement discomfort, but you should code only what is clearly documented.
When to use this code
Use this code when the clinician documents chronic inflammatory disease of the orbit without specifying the underlying condition, such as idiopathic or nonspecific orbital inflammation. It also fits when the note confirms orbital inflammation but lacks enough detail for a more precise code. Check documentation if the cause is unclear.
Do not use for
Do not use H05.10 for acute orbital inflammation, orbital cellulitis, or orbital disorders with a documented specific cause. If the record names a more specific inflammatory orbital diagnosis, code that condition instead.
Coding tip
Query for the exact orbital diagnosis and laterality if the note only says “orbital inflammation.”
