Radiology services for a unilateral x-ray of the hip; single view. c. what code(s) are listed for the procedure in the alphabetic index?

The code which is listed for the procedure in the alphabetic index is 73501

The section of the CPT which manual tubular lists verified the code is the index.

The description of the given code matches the scenario. The main term which is used in this alphabetic index of the CPT coding manual is the service. 
Unilateral X-ray is the subterm which best identifies the reason for the procedure. The location of the procedure is being identified by the hip.

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
