Scalene muscle injection
A patient with brachial plexus disorder with neck and upper back tightness presented for a scalene muscle injection. Preliminary sonographic images demonstrated conventional morphology of the left brachial plexus at the level of the scalene muscles. Under sonographic guidance and using 1% lidocaine as local anesthetic, a short 25-gauge needle was inserted into the anterior scalene muscle and 2.5 mL of lidocaine were injected. How is it determined whether a code should be assigned from the Medicine section or from the Musculoskeletal System? Therefore, what is the correct code assignment for a lidocaine injection into the anterior scalene muscle to treat the brachial plexus disorder? ...
