ICD-10 Code H05.24 – Constant exophthalmos (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.24 – Constant exophthalmos
What it is
H05.24 identifies constant exophthalmos, meaning a persistently protruding eye. Use it when the chart documents ongoing forward displacement of the globe rather than a temporary or intermittent finding.
Clinical signs
Typical findings include visible eye bulging, widened eyelid opening, and incomplete eyelid closure. Clinical features vary; refer to documentation for whether the protrusion is unilateral or bilateral and for the underlying cause.
When to use this code
Use this code when the provider clearly documents constant exophthalmos, proptosis, or persistent ocular prominence. It may appear in records for thyroid eye disease, orbital disease, or other confirmed causes, but you should code only what is documented.
If the note describes eye bulging without stating it is constant, check documentation before assigning H05.24. When a specific underlying disorder is documented, report that condition as well if the record supports it.
Do not use for
Do not use H05.24 for intermittent, transient, or unspecified eye protrusion. Do not assume the diagnosis from appearance alone; check documentation.
Coding tip
Confirm that “constant” is explicitly stated, because exophthalmos without that qualifier may require a different code.
