Transanal hemorrhoidal dearterialization

American Medical Association, AMA

Effective January 1, 2020 The new code, CPT 46948 more accurately describes all services inherent in the procedure, including identification and ligation of the terminal branches of the superior rectal artery through an anoscope equipped with an ultrasound probe and when required deployment of a ring of sutures to pull-up a prolapse (mucopexy). The ultrasound probe allows localization of all the arteries that are to be individually ligated as needed to interrupt hemorrhoid blood supply. THD is different from a traditional hemorrhoidectomy, which focuses on excising the hemorrhoidal bundle.
