KFF estimated that 3.8 million Part D enrollees met all modeled Bridge eligibility criteria in 2023, approximately 8% of that year’s Part D enrollment. Its analysis uses Medicare claims, encounter and prescription-event data, with assumptions about unchanged diagnosis and GLP-1 use for potential 2026 eligibility.
This estimate is not a count of people receiving Bridge drugs in 2026. It does not measure awareness, search volume or traffic that this website can acquire. The original article’s claims about the typical eligible beneficiary and lack of awareness were not established by the cited analysis and have been removed.
