Medicare Supplement plans (Medigap coverage) overview. Medicare Supplement (also known as MedSup or Medigap) coverage, is health insurance sold by private insurance companies to fill the âgapsâ in Medicare Part A and Part B coverage.
Radiofrequency ablation (RFA) is a minimally invasive procedure that destroys cancerous tumors. Pulses of radiofrequency energy are sent through a catheter (a long, thin tube) to heat and destroy diseased tissue. Currently, RFA is a standard treatment for patients with inoperable liver tumors.
RFA is now used in a multitude of settings for a variety of tumors. It was originally developed for patients who were not surgical candidates, but its use has now expanded to patients as a bridge to liver transplantation and even as a substitute for those who may be considered for surgical resection [ 13 ].
