ICD-10 Code H57.8A9 – Foreign body sensation, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H57.8A9 – Foreign body sensation, unspecified eye
What it is
This code identifies a patient-reported feeling that something is in the eye, without a specified foreign body or a more specific eye diagnosis. It is used when the sensation is documented but the exact cause is not yet defined.
Clinical signs
Patients may report grittiness, scratching, or the feeling of debris in the eye. Clinical features vary; refer to documentation for associated redness, tearing, blinking, or exam findings.
When to use this code
Use this code when the record documents foreign body sensation in an unspecified eye and no actual foreign body is identified. It may fit initial evaluations when symptoms are recorded but the cause remains unclear. If the provider later documents a specific disorder, code that condition instead.
Do not use for
Do not use this code for a confirmed retained foreign body in the eye or for a more specific ocular diagnosis. Check documentation if the sensation is clearly linked to trauma, infection, or another defined eye condition.
Coding tip
Code the symptom only when the provider documents it and no more specific eye diagnosis is available.
