D9211
Regional block anesthesia
The dentist administers a local anesthetic not in conjunction with operative or surgical procedures in D9210. Topical antiseptic and/or topical anesthetic may be applied to the area first. With a sterilized needle and the patient in position, the dentist inserts the needle into mucosa, injects several drops of local anesthetic solution, and begins slowly advancing the needle toward the target. More local anesthetic is injected before the periosteum is touched, and the local anesthetic is slowly deposited and the needle carefully withdrawn.
