Medicare risk adjustment for the frail elderly

Area of Science:

• Health Services Research
• Gerontology
• Health Economics

Background:

• The Centers for Medicare & Medicaid Services (CMS) has consistently sought methods to integrate frailty adjustment into risk adjustment strategies.
• The Hierarchical Condition Categories (CMS-HCC) model is a key component of Medicare risk adjustment for private health plans.

Purpose of the Study:

• To present research findings on Medicare risk adjustment for the frail elderly population.
• To evaluate the impact of frailty adjustment implementation for Program of All-Inclusive Care for the Elderly (PACE) organizations since 2004.
• To report on a revised frailty adjuster being phased in for PACE organizations from 2008 to 2012.

Main Methods:

• Analysis of Medicare risk adjustment data incorporating frailty metrics.
• Longitudinal evaluation of risk adjustment accuracy for frail elderly beneficiaries.
• Assessment of the revised frailty adjuster's performance in PACE settings.

Main Results:

• The study details the outcomes of Medicare risk adjustment for frail elderly individuals.
• Findings are presented regarding the effectiveness of frailty adjustment in PACE organizations.
• Performance data for the revised frailty adjuster during its implementation phase is discussed.

Conclusions:

• Frailty adjustment is a critical consideration for refining Medicare risk adjustment methodologies.
• The research provides insights into the evolving application of frailty adjusters for vulnerable populations.
• The revised frailty adjuster shows potential for improving risk prediction in specific Medicare programs.
