Modifier Notes

Timed code — bill in 15-minute units under the 8-minute rule (a minimum of 8 minutes is required to bill one unit). The GP modifier is often required to indicate services delivered under a physical therapy plan of care.

Reimbursement Expectations

OON reimbursement is inconsistent and plan-dependent. Cash/self-pay rates typically run $40-$80 per unit; insured patients recover a portion after meeting their deductible when the superbill itemizes units and total minutes.
