What This Code Means

Y73.1 is the ICD-10-CM diagnosis code for therapeutic (nonsurgical) and rehabilitative gastroenterology and urology devices associated with adverse incidents. An adverse event or injury caused by non-surgical therapeutic or rehabilitative devices used for gastrointestinal or urinary conditions, such as feeding tubes, ostomy pouches, or urinary collection devices. Y73.1 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).

Y73.1 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 nasogastric tubes, urinary drainage bags, or dialysis equipment.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y73.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Apply this code for complications from therapeutic devices like nasogastric tubes, urinary drainage bags, or dialysis equipment
  • Include documentation of the specific device type and the adverse outcome (e.g., leakage, skin irritation, dislodgement)
