I want to know where in cpt 2016 code book I can find the surgical package for code 47564? I look in the biliary tract note section and I can not find the description of the surgical package. One of the rational in my CPC exam book state the procedure includes incision of the common duct to extract stones and the insertion of a T-tube that is brought out through the abdominal wall, but I do note see that description in the cpt code book.
