Physical Rehabilitation

When billing for outpatient rehabilitation services and units described as “each 15-minute,” please adhere to the following guidelines when determining the total number of units to bill: 

• When only one service is provided in a day, providers should not bill for services performed for less than eight minutes.   
• For any single-timed CPT code in the same day measured in 15-minute units, bill a single 15-minute unit for treatment greater than or equal to eight minutes up to and including 22 minutes. 

If the duration of a single modality or procedure in a day is greater than or equal to 23 minutes, up to and including 37 minutes, then two units should be billed.       

Use appropriate time intervals for units.   

When more than one service, represented by 15-minute-timed codes, is performed in a single day, the total number of minutes of service determines the number of timed units to bill.
