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.
The area(s) where the RFA needle/probe will be inserted is injected with local anesthetic (numbing medication similar to what your dentist uses). RFA is accomplished by positioning the insulated radio-frequency needle/probe under fluoroscopy (x-ray) to the location of the nerve that is to be burned.
