CPT® Code 42320

The procedure described by CPT® Code 42320 refers to the drainage of an abscess located in the submaxillary gland, which is also known as the submandibular gland. This gland is one of the major salivary glands situated beneath the lower jaw, specifically in the triangle of the neck. It plays a crucial role in saliva production and secretion. An abscess in this gland, often resulting from infection or blockage, can lead to significant discomfort and complications if not addressed. The term 'sialadenitis' is commonly used to describe inflammation of the salivary glands, which can manifest as an abscess. The drainage procedure involves making an incision externally, below the jawline, to access the affected gland. This approach allows for effective drainage of the abscess, alleviating pressure and pain associated with the condition. The procedure is performed with careful dissection of the surrounding soft tissues and muscles, ensuring the protection of critical structures such as the mandibular branch of the facial nerve. Following the drainage, drains may be placed to facilitate continued drainage and prevent fluid accumulation, with the incisions being closed around these drains to promote healing.
