To estimate the number of Medicare beneficiaries eligible for the Medicare GLP-1 Bridge program covering GLP-1s for obesity.
Approach:
Eligibility Criteria Analysis: The analysis used 2023 Medicare claims and encounter data to estimate the number of beneficiaries with obesity or overweight and those meeting the Bridge eligibility criteria.
Key Findings:
An estimated 13.3 million Medicare beneficiaries had obesity or overweight in 2023, based on claims data.
Approximately 3.8 million Medicare Part D enrollees met the eligibility criteria for the Medicare GLP-1 Bridge in 2023.
The eligible population represents 8% of Medicare Part D enrollees and 7% of the total Medicare population in 2023.
Interpretation:
Limitations:
The estimate of 3.8 million eligible beneficiaries may be conservative as not all beneficiaries with obesity or overweight may have a claims-based diagnosis.
The actual number of eligible beneficiaries may change by 2026 due to shifts in diagnoses or GLP-1 use.
In two population-based cohorts, metabolically unhealthy status generally showed higher dementia risk estimates, while metabolically healthy obesity was not associated with increased risk in primary analyses.
