Plain-language verdict
As scored, the CMS file lists payment reduction Yes (Total HAC Score 0.8824; threshold 0.3792).
Reported on 2 of 6 measures; each reported measure moves the equal-weighted score by 0.5000 points.
Penalized as scored; would NOT be penalized on measured data alone — a mechanics illustration using measured-only mean -0.4069 vs threshold 0.3792, not a CMS prediction.
Describes scoring mechanics only. Not medical or legal advice. Any “would / would not” language is an illustration against the published threshold, not a CMS prediction.
