The LAN was launched in March 2015 to accelerate the adoption of alternative payment models (APM) and drive alignment in payment reform approaches across the public and private sectors. These payment models have the potential to realign treatment and payment incentives to improve health care quality while containing cost. Through the LAN’s collaborative structure, more than 7,100 participants are taking action towards APM adoption and implementation. The LAN has adopted the goal of tying 50% of U.S. health care payments to APMs by the end of 2018. In 2016, the LAN embarked on its first national APM Measurement Effort to assess the adoption of APMs and the progress toward the LAN’s goals. The 2018 LAN APM Measurement Effort marks the third year of this initiative.
