Tasks this bears on
Deciding whether to image at all
Protocolling: whether this study answers the clinical question, which sequence, how much contrast, how much dose — and whether to say no.

Where this applies
The Medicare payer's final rule. Under the 2014 statute, any clinician ordering advanced diagnostic imaging such as CT, MRI or PET must consult appropriate use criteria through qualified clinical decision support software. CMS says the statute's real-time, claims-based reporting requirement presents an insurmountable barrier to operationalising the program, finalises a pause of the program for reevaluation and rescinds its regulations, and says the expected savings are negligible because the program cannot be implemented as written; it adds that it expects clinical decision support to keep being used where it helps. The statute remains in force, the pause was for claims-processing rather than clinical reasons, and the program bound the ordering clinician, not radiologists.
What this means
The largest attempt to put software in front of every advanced imaging order — a national mandate — was paused before it bit, for operational reasons. Deciding whether a scan is worth doing has not been handed to rules; the people ordering and protocolling studies still carry it.
What it does not yet show
It is about Medicare's mandate on ordering clinicians and why it stalled, not about how often radiologists decline or change a requested study.
What you can check
Open the CY 2024 Physician Fee Schedule final rule (88 FR 78818) and find "presents an insurmountable barrier for CMS to fully operationalize the AUC program".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
