Chronic Pain Management Documentation

Best answers
Hello, I'm coding services for a new provider in our family medicine clinic, who is specializing in chronic pain management. She provides IMS/acupuncture, 21k Laster therapy-class 3B, and Alpha Stim-electrical stimulation. I need help with documentation guidelines. Our office follows 95 guidelines, but there is not much on procedures, especially on these new types of procedures. If some one can point me in the right direction, it would be much appreciated. :confused:
