How to code with multiple modifiers on following scenario

Can you please tell me if the following modifiers used are correct for billing on a Medicare patient? Here is the scenario:

75 y.o. female presents with complaint of Rt shoulder pain. She also has multiple skin lesions and wants them frozen-removed. After exam, doctor's assessment is that she has bursitis and performs a joint injection of the right shoulder. He also does 2 cycles of cryosurgery on Actinic Keratoses of the right shin, as well as, 2 cycles each of Seborrheic keratoses of the back and right temple areas. These were the codes chosen:

99213-25
17110
17000-59
206101-51

Can you please tell me if the correct modifiers were chosen, as well as, if we code x2 for each cycle of cryosurgery performed (I know CPT® states "each lesion" and doesn't mention # of cycles.

Thank you.
