For physicians who are selecting the 90-day reporting option for MACRA, your performance period should begin no later than October 2. However, participating at any level in 2017 will ensure your practice will not be hit with a negative 4 percent payment adjustment in 2019. Physicians who choose to report for 90 days may possibly earn a small bonus payment. For free assistance with any questions you may have about MACRA, please contact the ACCMA at (510) 654-5383.
