Which term serves as the data basis for most utilization outcome measures?

• A. Measure Exclusions
• B. Medicare Fee-for-Service Claims
• C. End-Result Outcome
• D. Utilization Outcome

Answer: (B)

The data source most utilization outcome measures rely on is administrative claims data, specifically Medicare Fee-for-Service Claims. Utilization outcomes track how much care a patient uses—things like hospital stays, skilled services, or home health visits—so having a standardized, billable record of services, dates, places of service, and providers is essential. Medicare Fee-for-Service Claims provide that comprehensive, comparable data across settings and over time, making them the primary basis for calculating these utilization metrics. Other terms listed don’t serve as the data source: measure exclusions are part of measure design, end-result outcomes describe the type of outcome (not the data used to compute it), and utilization outcome refers to the outcome category rather than the data source.
