CPT® Code 20526

A therapeutic injection, specifically referred to as a carpal tunnel or median nerve injection, is a medical procedure aimed at alleviating symptoms associated with carpal tunnel syndrome. This condition arises when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed, leading to pain, numbness, and weakness in the hand and fingers. The injection typically involves the administration of a local anesthetic, such as lidocaine, and/or a corticosteroid, such as methylprednisolone, directly into the affected area. This targeted approach helps to reduce inflammation and provide immediate pain relief, making it a preferred option for patients who may not respond adequately to other non-surgical treatments, such as oral medications or wrist splinting. The procedure is performed with precision, ensuring that the injection is delivered between the flexor carpi radialis and palmaris longus muscles, which are key anatomical landmarks in the wrist. By effectively addressing the symptoms of carpal tunnel syndrome, this injection can significantly improve the quality of life for individuals suffering from this condition.
