CPT® Code 24066

The procedure described by CPT® Code 24066 refers to a biopsy of the soft tissue located in the upper arm or elbow area, specifically targeting deeper structures such as subfascial or intramuscular tissues. A soft tissue biopsy is a medical procedure that involves the removal of a small sample of tissue for diagnostic purposes. The term "soft tissue" encompasses various types of tissues, including muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the connective tissues surrounding joints. This procedure is typically performed when there is a need to investigate abnormalities or lesions within these tissues. Prior to the biopsy, anesthesia—whether local, regional, or general—is administered to ensure patient comfort during the procedure. The area of the skin over the biopsy site is thoroughly cleansed to minimize the risk of infection. A surgical incision is then made, allowing the physician to carefully dissect through the layers of tissue down to the mass or lesion while taking precautions to avoid damaging any nearby blood vessels or nerves. Once the tissue sample is obtained, it is sent to a laboratory for histological evaluation, which is a separate reportable service. After the sample is collected, the incision is closed using sutures. It is important to note that CPT® Code 24066 is specifically designated for deeper biopsies that require more extensive dissection compared to superficial biopsies, which are coded under CPT® Code 24065.
