Durable LVAD Implantation & Cardiac Reoperation Scrubber

Durable ventricular assist device (LVAD) implantation represents one of the highest-acuity surgical procedures in medicine. Yet commercial payers aggressively downcode durable intracorporeal implants (33979) to temporary systems (33975), unbundle redo sternotomy adhesiolysis (+33530), and reject concurrent tricuspid valve annuloplasties. Protect your heart failure surgical revenue with automated clinical audit rules.
