You can report CPT codes 93308 (limited transthoracic echocardiography) and 93306 (complete transthoracic echocardiography) on the same day only if they represent distinct and medically necessary studies.
Still, these codes are generally not billed together for the same patient on the same date because 93306 includes a complete evaluation, while 93308 is for a limited or follow-up study that does not assess all cardiac structures.
