The 33010 is not listed as one of the inclusive procedures to critical care by CPT (See below), but it does bundle together.
The documentation for the Critical Care CPT code needs to clearly stated the time spent providing critical care and....."exclusive of procedures" to let the carrier know that the time spent performing the 33010 was not included. A modifier 25 is needed to separate the E&M from the procedure code.
