Cost is the fourth performance category under the MIPS program and makes up 15% of your total MIPS score for 2019 (up from 10% in 2018 and 0% in 2017). This category will steadily increase to 30% by the year 2022 when it will have the same weight as Quality. If CMS is unable to calculate a Cost score for a clinician, the category will be reweighted to Quality. While clinicians can relatively quickly change their MIPS Quality score by tracking some specific outcomes (e.g., track smoking status and give cessation advice), Cost is more challenging. It is more complex with many different variables, so monitoring Cost becomes important as it contributes more towards your final MIPS score. MDinteractive can help you access your CMS performance feedback reports which will provide your Cost score from prior MIPS reporting years.  In this article we will explore the different cost measures, how they are scored and the potential impact on your practice.
