CPT® Code 99070 is used to report the provision of additional supplies and materials by a physician or other qualified healthcare professional during a patient encounter that are not usually included in the basic service. This code applies when supplies are necessary for patient care but are not separately listed or included in the standard procedure or office visit.
Examples include specialized dressings, splints, sterile instruments, or other expendable items used during treatment.
