Will more eligible clinicians types be subject to the requirements of EHR reporting under MIPS?

From CMS MIPS rules, page 77037:

"In addition, we recognize that under MIPS, there will be more eligible clinicians subject to the requirements of EHR reporting than were previously eligible under the Medicare and/or Medicaid EHR Incentive Program, including hospital-based MIPS eligible clinicians, nurse practitioners, physician assistants, clinical nurse specialists, and certified registered nurse anesthetists. Since many of these non-physician clinicians are not eligible to participate in the Medicare and/or Medicaid EHR Incentive Program, we have little evidence as to whether there are sufficient measures applicable and available to these types of MIPS eligible clinicians under our proposals for the advancing care information performance category. As a result, we have provided additional flexibilities to mitigate negative adjustments for the first performance year (CY 2017) in order to allow hospital-based MIPS eligible clinicians, nurse practitioners, physician assistants, clinical nurse specialists, certified registered nurse anesthetists, and other MIPS eligible clinicians to familiarize themselves with the MIPS program. Section II.E.5.g.(8) of this final rule with comment period describes our final policies regarding the re-weighting of the advancing care information performance category within the final score, in which we would assign a weight of zero when there are not sufficient measures applicable and available."
