Yet the ASPE/HHS evaluation reveals that PACE does NOT reduce total costs—Medicare capitation rates are equivalent to FFS overall (with lower costs only in the first 6 months post-enrollment), while Medicaid costs are significantly HIGHER under PACE. The value is in restructuring care (community vs. institution, chronic vs. acute) and quality improvements (significantly lower nursing home utilization across all measures, some evidence of lower mortality), not in cost savings.
