CPT 93308 describes a non-invasive echocardiography procedure that uses ultrasound to produce images of the heart and performs M-mode recording to evaluate the volume of blood pumped by the heart.
What Is CPT Code 93308?
CPT code 93308 refers to echocardiography, a non-invasive test that uses ultrasound waves to produce images of the heart.
During the procedure, the patient is prepared, and a gel is applied to the chest. Next, a small transducer is placed on the chest wall, which sends high-frequency sound waves to the heart and receives the echoes that bounce back.
These echoes are then displayed on a monitor as images of the heart. M-mode recording is also performed during the procedure. This involves detecting the heart’s movement towards and away from the transducer to evaluate the volume of blood pumped by the heart.
The provider will view and re-evaluate any known cardiac abnormalities based on a previous complete echocardiography exam.
The CPT book describes CPT code 93308 as: “Echocardiography, transthoracic, real-time with image documentation (2D), includes M-mode recording, when performed, follow-up or limited study.”
When the patient is appropriately prepped, the provider applies a gel and places a small transducer on the chest wall.
The probe generates high–frequency sound waves that bounce off the heart back to the probe, which is connected to a monitor that displays the images of the heart. The gel helps the provider to move the probe in different directions on the chest to obtain views of the heart.
M–mode recording detects heart motion toward and away from the transducer to evaluate the volume of blood pumped by the heart.
The provider views and re–evaluates known cardiac abnormalities based on a previous complete echo.
How To Use CPT 93308
Suppose a cardiologist performs an echocardiogram and discovers a congenital anomaly. In that case, the appropriate codes to use are CPT 93303, CPT 93304, and CPT 93315 until CPT 93317, rather than a standard echocardiogram code such as CPT 93308.
This is true even if the anomaly has little or no clinical significance. However, if the echocardiogram does not reveal any congenital abnormalities, the appropriate codes to use are the normal ones (CPT 93307, CPT 93308, CPT 93312 until CPT 93314).
