Billing Timed Procedures
Provider Administrative Policy
DisclaimerOur provider administrative policies contain information regarding claims submission, reimbursement, and other information in order to achieve an efficient relationship with our providers. These policies are not an authorization or explanation of benefits. Blue Cross of Idaho retains the right to add to, delete from and otherwise modify this policy in accordance with our provider contracts.
CPT procedure codes may be timed procedures with the descriptions indicating services performed for "each 15 minutes." Time is the face to face 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 mid-point 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 24G of the CMS 1500 claim form.
This excludes billing units used for anesthesia (see PAP500)
