When you see patients during the postoperative global period, you should report or enter CPT code 99024. Entering this code in your practice management system reflects care provided during the postoperative period. Payors, particularly managed care or capitated plans, may require this documentation to substantiate charges or capitation payments.
Be sure to document all services and, because 99024 is a nonpayment CPT code, ensure that the charge is 0. If the payor does not require submission of 99024, set up the practice management system to allow the code to be posted, but turn off the feature to transfer it to the claim form.
