ICD-10 Code H57.8A2 – Foreign body sensation, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H57.8A2 – Foreign body sensation, left eye
What it is
This code identifies a documented sensation that something is in the left eye, even when no object is confirmed. Use it for unilateral left-eye complaints recorded as a foreign body feeling.
Clinical signs
Patients may report grittiness, scratching, or the feeling of an eyelash or particle in the left eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents foreign body sensation limited to the left eye and does not identify an actual retained object. It may apply in outpatient, urgent care, or emergency settings when symptoms are unilateral. Code the documented symptom rather than assuming injury.
Do not use for
Do not use it for a confirmed foreign body in the eye or for bilateral symptoms. Check documentation if the complaint is better described by corneal abrasion, conjunctivitis, or another eye disorder.
Coding tip
Verify laterality and whether a true foreign body was found before assigning H57.8A2.
