When is it appropriate to do limited echo 93308 and 93321?

Limited: You should report 93308 (Echocardiography, transthoracic, real-time with image documentation [2D], includes M-mode recording, when performed, follow-up or limited study) for an exam that doesnt evaluate -- or document the attempt to evaluate -- all the structures in the bulleted list below.
" Left and right atria
" Left and right ventricles
" Aortic, mitral, and tricuspid valves
" Adjacent portions of aorta.
AMAs CPT Assistant (September 2005) explains that the cardiologist may choose a 93308 service as a follow upto a complete exam when the patient only needs evaluation of a more focused area. Or you may see a limited exam chosen in certain emergent situations.
Documentation: Remember that you need a report that includes interpretation of all obtained information, documentation of all clinically relevant findings including quantitative measurements obtained, plus a description of any recognized abnormalities. Pertinent images, videotape, and/or digital data are archived for permanent storage and are available for subsequent review. If you dont meet these requirements, you cant report the echo separately.
Same principle applies to 93321 also being a add-on code.
