What This Code Means
Y74.1 is the ICD-10-CM diagnosis code for therapeutic (nonsurgical) and rehabilitative general hospital and personal-use devices associated with adverse incidents. An adverse event or injury caused by non-surgical therapeutic or rehabilitative devices used in general hospital settings or for personal use, such as infusion pumps, oxygen delivery systems, or mobility aids. Y74.1 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering medical devices associated with adverse incidents in diagnostic and therapeutic use (y70-y82).
Y74.1 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.
Apply this code for complications from therapeutic devices like IV pumps, oxygen concentrators, wheelchairs, or hospital beds.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y74.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
