The MIPS final score determines a provider's Medicare Part B payment adjustments. MIPS also created a means for consumers to rank providers.

MIPS scores are calculated using four performance categories, quality, cost, improvement activities, and promotion of interoperability. Higher scores are better.: The highest final MIPS score is 100.
