ASIPP was founded in November 1998 as the Association of Pain Management Anesthesiologists (AOPMA) to represent interventional pain physicians dedicated to improving the delivery of interventional pain management services to patients across the country in the various settings of ambulatory surgical centers, offices, and hospital outpatient departments. The name seemed to exclude some physicians and other professionals, so it was changed unanimously to the American Society of Interventional Pain Physicians. In addition, ASIPP also started the Interventional Pain Physician-PAC of AOPMA in December 1999 to represent the advocacy interests of interventional pain physicians. Its name was changed to American Society of Interventional Pain Physicians-PAC.
