Assessment. We specifically asked for feedback on whether to retire SNP-specific measures since these measures focus on processes of care and are only applicable to a subset of contracts and enrollees. Our Star Ratings contractor, RAND Corporation, convened a Technical Expert Panel in late October 2024 to obtain feedback related to making enhancements to the Part C and D Star Ratings measure set. The TEP did not recommend making the measurement set smaller given the high stakes nature of the Part C and D Star Ratings program, but the TEP did support rethinking the measures included. Overall, there was support for the current HEDIS, CAHPS, HOS, and some of the operational measures. Suggestions included the following: adding more evidence- based clinical outcomes measures or redesigning current measures to assess patient outcomes (such as medication adherence); considering relevance, reliability, and the small denominator for some measures; considering “gameability,” attribution issues, provider burden, and the sensitivity of measures to small changes; and considering measures focused on trust with the plan and network issues. We asked for feedback from all interested parties on ways to simplify and refocus the measure set. Commenters provided mixed support for simplifying the overall measure set and focusing more on clinical care, outcomes, and patient experience. Some commenters were supportive of removing some or all of the measures focused on operational performance, while other commenters raised concerns about reducing the number of measures, retiring measures where plans do well, and removing measures where plans have more control over their performance. There was mixed reaction to removing the Part C and D call center measures. For the call center measures, a few commenters mentioned limitations of the current measures due to a small number of calls causing significant shifts in performance, other commenters suggested increasing the number of calls made or removing the TTY component of the call center measures, and some commenters opposed removing these measures since they promote access for people with limited English proficiency and people with disabilities. We received mixed support for retiring the complaints measure, with some commenters noting that the complaints measure is an integral component of the program and is within the control of Part C and D contracts. The majority of commenters did not support retiring the Part C appeals measures, noting that these measures safeguard patients and promote accountability and transparency. There was mixed feedback on retiring the Medicare Plan Finder Price Accuracy measure, with some commenters saying that it helps ensure that consumers have accurate information about drug prices and others stating that the measure is effectively topped out. We received mixed feedback on the retirement of the MTM measure. Although some commenters supported the retirement of this measure, the majority of commenters were opposed to retirement until CMS adopts an outcomes-based MTM measure as a replacement. Similarly, we received mixed support for retiring the SNP Care Management measure. Those in support of
