ICD-10 Code H05.252 – Intermittent exophthalmos, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.252 – Intermittent exophthalmos, left eye
What it is
H05.252 identifies intermittent protrusion of the left eyeball. Use it when the record specifically documents exophthalmos that comes and goes in the left eye.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe visible forward displacement of the left eye that is episodic, sometimes associated with orbital fullness or asymmetry.
When to use this code
Use this code when the clinician documents intermittent exophthalmos limited to the left eye. It is appropriate for outpatient, specialist, or follow-up notes when the diagnosis is confirmed or clearly stated. If the chart mentions proptosis only without laterality or intermittency, check documentation.
Do not use for
Do not use this code for generalized exophthalmos, right eye involvement, or bilateral disease. If the note describes another orbital disorder without explicit intermittent left-sided protrusion, choose a more accurate code.
Coding tip
Confirm both laterality and intermittency in the provider’s documentation before assigning H05.252.
