There's lots of codes that are divisible into the technical/professional components...such as xrays, scans, other diagnostic testing such as echocardiograms, nuclear stress testing, EEG's, conduction studies, etc. There are also some lab codes that are as well. The easiest way to see if a code is divisible is to look it up on the Medicare fee schedule, and select TC or 26. The TC modifier is usually the facility that owns the equipment used to perform the procedure. The 26 is the person who reads/interprets the procedure. An example is our cardiologists own the echo machine in their office, when they bill, they don't use any modifier because they are billing globally- for both TC and 26. When they see a patient in house/inpatient they bill with the 26 modifier because the only they are doing is reading/interpreting the test. The hospital owns the echo equipment for which they are billing for the technical component.
