WiSER: What ASA is doing

ASA is extremely concerned about the WISeR model and its effects on anesthesiologists, pain medicine physicians, and patients. This prior authorization model will dramatically increase the volume of items and services subject to prior authorization, which has historically not been utilized in Medicare Fee-for-Service (Original Medicare (Parts A & B)). In addition, WISeR will contribute to an already high administrative burden on physician practices and introduce barriers to care that can negatively impact patients’ health outcomes.

ASA is actively engaged in advocacy as part of a coalition of organizations whose members are affected by WISeR. Here is ASA’s response:

• On March 30, 2026, ASA convened a member town hall on Medicare’s WISeR Model for practices in the six mandatory participation states. Members from 15 states participated. The discussion surfaced real time implementation challenges, emerging operational issues, and areas of concern including delays in care due to the model rollout. Member insights will inform the ASA’s advocacy strategy and the development of practical resources to support members navigating WISeR requirements.

• ASA joined a coalition of surgical and specialty organizations in a letter to CMS expressing concerns with this model.

• ASA joined a coalition in a letter to the House Appropriations Committee to express support of an amendment to halt funding for WISeR.

• ASA advocates for other efforts to root out fraud, waste, and abuse that do not undermine or delay care.
