Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with advanced heart failure supported by a durable left ventricular assist device (LVAD) presents for replacement of a malfunctioning monitor/display module integral to the electric or electric/pneumatic ventricular assist device. The patient is typically seen in an outpatient advanced heart failure clinic or device clinic, or admitted to the hospital if the device alarm indicates critical function loss. The clinical workflow includes device interrogation by LVAD-trained biomedical engineering staff, confirmation of monitor/display module failure, verification of device compatibility and serial numbers, preparing the patient with monitoring and anticoagulation review, and performing the module replacement in a procedure room or operating room depending on local protocols and patient stability. Post-replacement steps include device testing, documentation of the replaced module serial number, programming checks, patient education on alarms and follow-up, and communication with the durable medical equipment supplier and the patient’s heart failure cardiologist for ongoing device management.
