CPT® Code 64809

The sympathetic nervous system is a critical component of the autonomic nervous system, responsible for regulating involuntary bodily functions such as sweating, blushing, and salivation. A sympathectomy is a surgical procedure that involves the destruction or excision of sympathetic nerve fibers to alleviate certain medical conditions. Specifically, CPT® Code 64809 refers to a thoracolumbar sympathectomy, which is typically performed to manage malignant hypertension, a severe form of high blood pressure that can lead to serious health complications. During this procedure, an incision is made in the lateral aspect of the chest and extended down to the iliac crest. This approach allows the surgeon to access the sympathetic chain, which is then divided using electrocautery to ensure precise cutting and coagulation. In some cases, a segment of the sympathetic chain may be removed entirely. The procedure aims to obliterate the ganglia, effectively severing the sympathetic chain and preventing the regrowth of nerve fibers. This intervention is particularly beneficial for patients who do not respond to conventional treatments for their conditions.
