Average total cost, sometimes referred to as the per unit total cost, is the per unit cost. This includes fixed costs, those costs that are required for production but do not change based on output, and variable costs, those costs that increase (or decrease) as output increases (or decreases).
The basic stress test involves walking on a treadmill while your electrocardiogram (EKG) is continuously monitored for changes that may indicate a blocked artery to the heart. However, there are options if you are unable to walk on a treadmill or if your EKG is already abnormal at rest. The existing options include: imaging stress tests -- echocardiographic or nuclear -- and pharmacologic stress tests -- adenosine and dobutamine.
Question: Can nurse practitioners (NPs) and physician assistants (PAs) charge for interpreting EKGs using 93010 (electrocardiogram, routine ECG with at least 12 leads; interpretation and report only) or for reading EKG rhythm strips using 93042 (rhythm ECG, one to three leads; interpretation and report only)?
