What This Code Means
H44.629 is the ICD-10-CM diagnosis code for retained (old) magnetic foreign body in iris or ciliary body, unspecified eye. A magnetic foreign object that has been lodged in the iris or ciliary body (colored part of the eye or muscle that controls lens focus) for an extended period, and the specific eye affected is not documented. This is typically a result of a past eye injury that was not immediately removed. H44.629 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of vitreous body and globe (h43-h44).
H44.629 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.
Use this code only when the documentation does not specify whether the foreign body is in the right eye (H44.621), left eye (H44.622), or when truly bilateral/unspecified. Query the provider if laterality can be determined from clinical notes or imaging.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H44.629 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the documentation does not specify whether the foreign body is in the right eye (H44.621), left eye (H44.622), or when truly bilateral/unspecified. Query the provider if laterality can be determined from clinical notes or imaging.
- •Ensure the foreign body is documented as magnetic and retained/old (not acute/recent). If the foreign body is non-magnetic, use code H44.629 from the non-magnetic series instead (H44.629 is specifically for magnetic bodies).
