NCS/Nerve Conduction Studies

Debate in my office on counting Nerve Conduction Studies. I know they are "per study" and not "per nerve", but I'm looking for some advice on how to code (count) the following. How many studies do you see here?

Motor Nerve Conduction Study

Median Left

Median Right

Ulnar Left

Ulnar Right

Sensory Nerve Conduction Study

Median Left

Median Right

Ulnar Left

Ulnar Right

Radial Left

Radial Right

Palmar Left- Median Palm and Ulnar Palm

Palmar Right- Median Palm and Ulnar Palm

Any help would be greatly appreciated!
