Clinical context

Separate clinical guidance indicates that falls can be prevented by screening to detect risk factors and prescribing tailored interventions, a process within the scope of physical therapist practice. 2

Coverage and utilization context

Fall risk screening is a reimbursable service for physicians during the introductory Welcome to Medicare wellness visit, but fall screening is not reimbursed under Medicare for subsequent wellness visits. 2

Fall assessment is identified as a reimbursable service and a Physician Quality Reporting Initiative indicator, whereas fall screening serves as a quality indicator for Meaningful Use and Accountable Care Organization initiatives. 2
