Frequently asked questions

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.

No. CPT guidelines specify that Doppler studies are reported with separate add-on codes and are not included in the limited TTE code 93308.

A "limited" study (93308) is defined as an echocardiographic exam that does not evaluate or attempt to evaluate all the cardiac structures required for a complete study (93306), typically performed to address a focused clinical concern or follow-up, and must be clearly documented as such.
