Greetings,I have read most of the NCS posts and see that most of these are done with an EMG. The code I come up with for this test is 95909 - Nerve conduction studies; 5-6 studies. I would like to know if the comparison hand is also counted, then the code should be 95912. Any feedback greatly appreciated.

I have a similar question Patricia. For the comparison study you have listed:

Comparison Summary Table

Left Median/Ulnar Palm Comparison (Wrist - 8cm)

Right Median/Ulnar Palm Comparison (Wrist - 8cm)

This is counted as 2 tests? I am confused because of both the nerves referenced. I wasn't sure to allow 2 or 4??
