What This Code Means
Z89.232 is the ICD-10-CM diagnosis code for acquired absence of left shoulder. A person who has lost their left shoulder and arm due to amputation or other acquired cause. Z89.232 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).
Z89.232 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.
Shoulder disarticulation involves loss of the entire upper limb including the shoulder joint.
