Risk Adjustment for Alzheimer Disease and Related Dementias in Medicare Advantage and Health Care Experiences
In this cross-sectional study of MA beneficiaries, reintroducing ADRD HCCs into the MA risk adjustment model was associated with improved care access and reduced financial burden among MA beneficiaries with ADRD. These findings suggest that risk adjustment that better reflects the costs of chronic, complex conditions may better align MA plan incentives with the needs of high-need populations and promote care equity.
