ICD-10 Code H05.2 – Exophthalmic conditions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.2 – Exophthalmic conditions
What it is
H05.2 identifies exophthalmic conditions, meaning abnormal forward protrusion of one or both eyes. Use it when the record documents exophthalmos or proptosis as the diagnosis.
Clinical signs
Typical findings include visibly prominent eyes, eyelid retraction, and reduced ability of the eyelids to cover the globe. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents exophthalmos, proptosis, or an exophthalmic condition without a more specific cause. It may appear in thyroid-related eye disease, orbital mass, or inflammation, but you should code the documented diagnosis. If the note only describes eye prominence, confirm the exact condition.
Do not use for
Do not use H05.2 for general eye disease without protrusion or for unrelated orbital disorders. If the provider names a different orbital or thyroid diagnosis, code that condition instead.
Coding tip
Always look for the documented cause of the eye protrusion, because H05.2 is appropriate only when exophthalmic conditions are specifically stated.
