Stick to 1 Unit of 73218 in This Case

Question: May I report two units of 73218 for the left humerus and the left forearm?

Answer: Code 73218 (Magnetic resonance [e.g., proton] imaging, upper extremity, other than joint; without contrast material[s]) specifies "upper extremity."

Because the left humerus and left forearm belong to the same upper extremity, you should report one unit.
