What This Code Means
Z89.221 is the ICD-10-CM diagnosis code for acquired absence of right upper limb above elbow. The person has lost their right arm above the elbow, including the upper arm and potentially the shoulder area. Z89.221 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).
Z89.221 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.
This code indicates amputation ABOVE the elbow on the RIGHT side; verify the amputation level is proximal to the elbow.
