CPT® Code 38510

The procedure described by CPT® Code 38510 involves the open biopsy or excision of deep cervical lymph nodes, which are critical components of the lymphatic system located in the neck region. These lymph nodes include specific groups such as the spinal accessory chain, transverse cervical chain, and the Delphian node. The procedure begins with the creation of an incision in the skin over the affected deep cervical lymph nodes, allowing access to the underlying structures. The platysma muscle, a thin layer of muscle in the neck, is then incised to facilitate deeper dissection. Careful dissection through the surrounding soft tissues is essential to protect nearby nerves and blood vessels, which are vital for maintaining normal neck function and sensation. During the procedure, one or more deep cervical lymph nodes are meticulously dissected free from their surrounding tissues and either removed entirely or sampled for further analysis. Additionally, lymph nodes located within the scalene fat pad, which is situated beneath the inferior aspect of the scalene muscle, may also be targeted for biopsy or excision. Accessing these lymph nodes requires a supraclavicular skin incision, which is extended through the platysma muscle and involves dividing the sternocleidomastoid muscle near its attachment to the clavicle. This approach exposes the scalene fat pad, allowing for careful dissection and removal of the fat pad along with any lymph nodes present. The excised tissue samples, lymph nodes, and scalene fat pad are subsequently sent to a laboratory for histological evaluation, which is crucial for diagnosing potential pathologies. It is important to note that CPT® Code 38510 is specifically used when the deep cervical lymph node biopsy or excision is performed without the excision of the scalene fat pad, while CPT® Code 38520 is designated for cases where scalene fat pad excision is included in the procedure.
