although this link says it is 73620 of both feet:


Incorrect. Modifier 76 is only used if more than one CPT code is used same encounter. Ex: 73650-RT, and 73650-76-RT. If performed in a hospital setting, they must append 26 modifier. 77 modifier is used when same imaging, different providers, same encounter.
