The MIPS Improvement Activity (IA) performance category is new for 2017; there was no analogous program in previous years.CMS MIPS Performance Category Weights The IA category requires eligible practitioners to attest to completing a certain number of CMS-approved activities over the course of the year, with each activity taking place over at least 90 days. This category will count for 15% of the overall MIPS Performance Score.


The number of required activities depends on whether the group or individual is considered “patient facing” or “non-patient facing.” If an individual or group practice has billed more than 100 patient facing encounter codes in the past year, they will be considered patient facing. CMS has released the list of all patient facing encounter codes to help physicians determine their status. For more information, see ACR’s Patient Facing Clarification write-up.

Patient facing clinicians will be required to attest to either two high-weighted Improvement Activities or four medium-weighted activities, while non-patient facing clinicians, groups of fewer than 15 participants and those in rural or health professional shortage areas will only have to attest to one high-weighted activity or two medium-weighted activities. 

You can review all 92 available MIPS Improvement Activities, with the ACR’s notes on which activities might be especially relevant to radiologists in Column H.MIPS IA Suggested Activities

            For MIPS reporting, only an attestation is required to receive credit for completing Improvement Activities. However, please note that Columns F and G in the above spreadsheet include CMS’s suggested documentation for each activity. In the event of an audit, practices will need to ensure they have documentation confirming the completion of the activity.MIPS IA Suggested Activities Col. F-G

            Participants in the ACR’s NRDR QCDR can attest to Improvement Activities using the MIPS Portal at Those who choose to submit using Claims or Qualified Registries can attest to Improvement Activities using a web interface soon to be available on the CMS website.
