Our Medicare B Carrier, National Govt Services, just released sentinel lymph node policy, Article A47181, which states that 38792 is appropo for the surgeon injecting dye AND/OR other substances for ID of sentinel node.
"CPT code 38792 can be billed for both the injection of radioactive tracer when performed without lymphoscintigraphy; and for the injection of vital dye (Isosulfan Blue Dye or a similar product) to visualize the sentinel node, by the surgeon/physician who performs the injection." [I cut and pasted that line from the article on the NGS website]
