CPT® Code 76873

The CPT® Code 76873 refers to a specific ultrasound procedure known as a transrectal ultrasound for the purpose of conducting a prostate volume study. This procedure is particularly significant in the context of brachytherapy treatment planning, which involves the implantation of radioactive seeds to treat prostate cancer. During the transrectal ultrasound, a specialized ultrasound probe is carefully inserted into the rectum. This positioning allows for a clear view of the prostate gland and surrounding tissues. The ultrasound technique utilizes sound waves that are transmitted through the body tissues; these waves reflect off the tissues and return to the probe. The returning echoes are then converted into electrical signals, which are processed and displayed as images on a monitor. This imaging provides critical information regarding the size and shape of the prostate, which is essential for determining the most effective approach to brachytherapy. By accurately measuring the prostate volume, the physician can make informed decisions about the placement and dosage of radioactive beads, ultimately aiming to optimize treatment outcomes for patients diagnosed with prostate cancer.
