Second Plan Preview of 2023 Part C and D Star Ratings Data
CENTER FOR MEDICARE
DATE: September 7, 2022
TO: All Medicare Advantage Organizations, Prescription Drug Plans, and Section 1876
FROM: Amy Larrick Chavez-Valdez – Director, Medicare Drug Benefit and C & D Data Group
SUBJECT: Second Plan Preview of 2023 Part C and D Star Ratings Data
The purpose of this memorandum is to inform Part C and D sponsors that they can preview their
Star Ratings data in the Health Plan Management System (HPMS) prior to display on the
Medicare Plan Finder (MPF). The second plan preview will be available September 8, 2022 and
will end on September 15, 2022 at 5:00 p.m. ET. We have made measure data revisions and
Technical Notes updates following the first plan preview. Additionally, each contract’s
preliminary Star Ratings for each measure, domain, summary score, and overall score will be
displayed, including any applicable disaster adjustments. We have also added a file in HPMS
with data for one Part C and one Part D measure for contracts to check the CMS programming.
The 2023 Star Ratings are scheduled to be released via the MPF on Medicare.gov on or about
October 6, 2022.
During this second plan preview, CMS expects Part C and D sponsors to again closely review
their posted data for each measure, as well as their preliminary Star Rating assignments.
Sponsors should immediately alert CMS of any suspected data issues or errors during the plan
preview in order to allow sufficient time to investigate and process any necessary data
corrections. If you print or save the data displayed on the HPMS Star Rating preview pages,
please double check the current values online prior to submitting emails in case any updates have
been made. Prior to the release of data on the MPF, all data in HPMS will be updated with the
final 2023 Star Ratings. As a reminder, we are unable to make changes to the 2023 Star Ratings
methodology that has previously been codified at §§ 422.160 – 422.166 and 423.180 – 423.186.
