Provider Administrative Policy
Our provider administrative policies contain information regarding claims submission, reimbursement, and other information in order to achieve an efficient relationship with our providers.

CPT procedure codes may be timed procedures with the descriptions indicating services performed for "each 15 minutes". Time is actual face to face time spent with the patient.
Per CPT and CMS requirements, to help define the number of units to bill for the procedure, you must determine the time spent performing the procedure. A unit of time is attained when the midpoint is passed. For example; 15 minutes is attained when 8 minutes have elapsed (more than midway between 0 and 15 minutes).
- 0 - 7 minutes = 0
- 8 - 22 minutes = 1 unit
- 23 - 37 minutes = 2 units
- 38 - 52 minutes = 3 units
- 53 - 67 minutes = 4 units
- 68 - 82 minutes = 5 units
- 83 - 97 minutes = 6 units
- 98 - 112 minutes = 7 units
- 113 - 127 minutes = 8 units
Please indicate total units in box 24 G of the CMS1500 claim form.
This excludes billing units for anesthesia (see PAP500)
