CPT code 93351 describes a transthoracic echocardiography procedure that uses ultrasound to produce images of the heart during rest and exercise and includes continuous electrocardiographic monitoring and interpretation of a report on the hemodynamic and echocardiographic responses to stress.
What Is CPT Code 93351?
CPT 93351 refers to transthoracic echocardiography, a non-invasive test that uses ultrasound waves to produce heart images.
During the procedure, a tiny probe is placed on the patient’s chest and generates ultrasound in M mode, which captures the one-dimensional motion and position of the heart and its chambers on a paper strip.
The provider records images of the heart while the patient is at rest and then again while the patient is exercising on a treadmill or stationary bike.
The provider may also use medication to perform the procedure. The images are recorded in videotape and digital cine loop formats, which allows the images to be reviewed cyclically and stored on floppy disks for future reference.
The provider also performs continuous electrocardiographic monitoring and interprets a report on the duration of stress, the reason for stopping, the hemodynamic stress response, and the echocardiographic response to stress.
The CPT book describes CPT code 93351 as: “Echocardiography, transthoracic, real-time with image documentation (2D), includes M-mode recording, when performed, during rest and cardiovascular stress test using a treadmill, bicycle exercise and/or pharmacologically induced stress, with interpretation and report; including the performance of continuous electrocardiographic monitoring, with supervision by a physician or other qualified health care professional.”
The provider applies a gel and places a small probe on the chest wall. The probe generates ultrasound in M mode that captures the one-dimensional motion and position of the heart and its chambers on a paper strip.
This procedure is known as two–dimensional motion. The provider records a sequence of sections of images once while the patient is at rest and then again while the patient exercises on a treadmill or stationary bicycle.
The provider may perform this procedure with or without medication in videotape and digital cine loop formats that allow echocardiography images in a digital form as a sequence of a determined frame number. These images can be reviewed cyclically.
The digital images can then be stored on floppy disks so that the image database can be an accurate tool for clinical use. She then supervises continuous electrocardiographic monitoring.
She interprets a report of the duration of stress, the reason for stopping, the hemodynamic stress response, and the echocardiographic reaction to stress.
How To Use CPT 93351
If you report CPT code 93351 with modifier 26, do not report it with CPT 93016, CPT 93018, or CPT 93350 with modifier 26.
