What This Code Means
H57.8A2 is the ICD-10-CM diagnosis code for foreign body sensation, left eye. A patient experiences an uncomfortable feeling that something is in their left eye, even though there may not be an actual foreign object present. This sensation can be caused by dry eyes, irritation, or residual effects from a previous foreign body. H57.8A2 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering other disorders of eye and adnexa (h55-h57).
H57.8A2 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify laterality is documented as left eye (H57.8A2) and ensure it's not bilateral or right eye, as each has a distinct code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H57.8A2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as left eye (H57.8A2) and ensure it's not bilateral or right eye, as each has a distinct code
- •Investigate the underlying cause of the foreign body sensation (dry eye, corneal abrasion, post-removal irritation) and code any confirmed diagnoses separately
