Hi,
description for the CPT 71022 states "Radiographs are taken of the patient's chest with the patient in a standard front to back (AP) position, as well as side to side (laterally). In addition, right and left obliques, or angled views, are taken. The key element of this code is that it reports specifically frontal, lateral, and oblique views".
If only RAO and LAO views are taken without AP and Lateral views, i would use 52 modifier with 71022.
Any other thoughts from anyone?
