We have a pt who comes in and gets an injection of B12 (her own meds) for Herpes Zoster. Can a 99211 be billed since the phys. does not directly supervise? I know some info. I have read states this code cannot be used for just an injection. However, the CPT states that if a physician is not present to use the 99211 instead of the injection admin code 96372. I know there has been alot of discussion concerning this matter but I need a little more. Is there a definite answer?
