CPT® Code 15841

The procedure described by CPT® Code 15841 involves the use of a free muscle graft to address facial nerve paralysis. This condition can result in significant functional and aesthetic challenges for patients, as it affects the ability to control facial expressions. In this surgical intervention, the physician first obtains a graft, which is typically harvested from the fascia lata, a layer of connective tissue found in the leg. The harvested graft is then carefully transplanted to the facial area, where it is sutured beneath the skin. This technique aims to partially restore movement in the areas of the face that have been affected by paralysis. The use of a free muscle graft is specifically indicated in cases where traditional methods may not suffice, providing a more effective means of reanimating the facial muscles. It is important to note that this code is distinct from others in the same category, such as CPT® Code 15842, which pertains to free muscle flaps utilizing microsurgical techniques, and CPT® Code 15845, which refers to regional muscle transfers.
