Cannot Find Doctor to Shadow

I am looking for a doctor to shadow. I asked my primary care physician and he said that students cannot simply ask to shadow a physician. He claims that paperwork must be filled out regarding HIPAA and that students have to apply to shadow physicians through college programs. However, I see that many people on this forum were able to call doctors offices. Should I just start calling doctor's offices? Is there any paperwork I need to fill out in order to shadow?
