Figure 2: CMS Total Effectuated Enrollment by Month, 2024 vs. 2025 (July-December), Compared with

enrollees who said they had filed and reconciled their Advance Premium Tax Credits (APTCs) actually did so. Enrollment in the figure is national

enrollment, while numbers in text boxes refer to subsidy removals for FFE removals only

If the theory that improper and phantom enrollment have a structurally lower MLR is

correct, there could be a mechanical upward shift in acuity based on the data in CMS’s

report. 2M of improper enrollment lost in early 2026 vs December 2025 would reflect

slightly less than 10% of total enrollment and would create HSD% pressure on MLR if the

phantom/improper enrollment had a <25% MLR. We think this could be captured by the

morbidity assumptions in 2026 bids; however, it is a point to monitor, and, all else equal, we
