CPT® Code 42870

The procedure described by CPT® Code 42870 involves the excision or destruction of the lingual tonsil, which is a mass of lymphoid tissue situated at the posterior aspect of the tongue. This procedure can be performed using various methods, and it is classified as a separate procedure, indicating that it is distinct from other surgical interventions. The lingual tonsil plays a role in the immune response, and its removal may be indicated in certain clinical scenarios. During the procedure, a mouth prop is typically utilized to keep the mouth open and provide access to the lingual tonsil. Surgeons may employ different techniques for dissection, including the use of scissors, curettes, cautery, radiofrequency, or laser ablation, depending on the specific requirements of the case. In some instances, access to the lingual tonsil may necessitate an incision in the neck. Control of bleeding during the procedure is critical and can be achieved through various methods such as applying pressure, using suture ties, or employing cautery techniques to minimize blood loss and ensure patient safety.
