CPT® Code 42305

The procedure described by CPT® Code 42305 refers to the drainage of a complicated abscess located in the parotid gland, which is one of the major salivary glands situated in front of the ears. This condition, known as sialoadenitis, involves the accumulation of pus within the gland due to infection or obstruction. The parotid glands are significant as they produce saliva, which is essential for digestion and oral health. During the procedure, a surgical incision is made anterior to the ear and extends beneath the jawline, allowing access to the gland. The surgeon raises skin flaps to expose the underlying fat and fascia, which are carefully dissected to reveal the parotid gland. Multiple incisions may be made in the gland itself, parallel to the branches of the facial nerve, to effectively drain the pus from the abscess cavity. Following drainage, the cavity is irrigated with sterile saline or an antibiotic solution to ensure cleanliness and reduce the risk of further infection. Drains may be placed to facilitate ongoing drainage if necessary, and the incision is subsequently closed. It is important to differentiate this procedure from simpler drainage methods, as CPT® Code 42305 is specifically designated for more extensive cases requiring multiple incisions.
