ICD-10 Code H05.249 – Constant exophthalmos, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.249 – Constant exophthalmos, unspecified eye
What it is
Use this code for persistent forward protrusion of the eyeball when the eye is not otherwise specified. It indicates a constant, ongoing finding rather than a temporary appearance.
Clinical signs
Typical documentation may note visible bulging of one or both eyes, prominence of the globe, or reduced eyelid closure. Clinical features vary; refer to documentation.
When to use this code
Assign H05.249 when the provider documents constant exophthalmos and does not identify the affected eye. Use it for office notes, consults, or problem lists that clearly describe persistent proptosis without laterality.
If the record names the eye, code the specified laterality instead. Check documentation when exophthalmos is described with an underlying disorder, because the associated condition may also need coding.
Do not use for
Do not use this code for intermittent or transient eye prominence, or when the chart documents a different orbital disorder. Do not assume laterality if the provider did not state it.
Coding tip
Verify whether the note says constant and unspecified before selecting H05.249; laterality or a different orbital diagnosis changes code choice.
