8 min rule

The 8-minute rule is a billing guideline used in physical therapy and other time-based medical services under Medicare. It allows healthcare providers to bill for one unit of service if they spend at least 8 minutes performing a time-based procedure. For every additional 15-minute block of time, another unit can be billed, as long as the total time meets or exceeds the required threshold. The rule ensures accurate billing and reimbursement based on the actual time spent delivering care.
