CPT® Code 64417

The CPT® Code 64417 refers to the procedure of injecting anesthetic agents and/or steroids into the axillary nerve, which is a specific type of nerve block. This procedure can serve both diagnostic and therapeutic purposes. The axillary nerve is a critical component of the brachial plexus, originating at the level of the axilla (armpit area). It branches into anterior and posterior trunks, with the anterior trunk primarily supplying sensation to the middle and anterior surfaces of the deltoid muscle, while the posterior trunk innervates the teres minor and the posterior deltoid muscle. The injection of anesthetic or steroid agents into this nerve can help alleviate pain, reduce inflammation, and improve function in the shoulder region. The procedure may also involve imaging guidance to ensure accurate placement of the needle, enhancing the effectiveness of the nerve block and minimizing potential complications. This careful approach is essential for achieving optimal outcomes in patients experiencing shoulder pain or related conditions.
