CPT® Code 27324

The CPT® Code 27324 refers to a biopsy procedure performed on the soft tissues of the thigh or knee area, specifically targeting deep tissues that are either subfascial or intramuscular. Soft tissues encompass a variety of structures, including muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the tissues that surround joints. This procedure is typically conducted under local, regional, or general anesthesia, or conscious sedation, depending on the specific site and depth of the biopsy being performed. Prior to the biopsy, the skin over the designated area is thoroughly cleansed to minimize the risk of infection. A surgical incision is then made, allowing the physician to carefully dissect through the tissue layers down to the mass or lesion of interest, while taking precautions to avoid damaging any nearby blood vessels and nerves. Once the tissue sample is obtained, it is sent to a laboratory for histological evaluation, which is reported separately. After the sample collection, the incision is closed using sutures. It is important to note that this code is specifically for deeper biopsies that require more extensive dissection compared to a superficial biopsy, which is coded under 27323.
