Analgesia - Dental Procedure Code Description

This dental procedure code applies to the dental use of inhalation nitrous oxide to reduce anxiety during a variety of dental procedures. This code refers only to anxiety-controlling drugs, not local anesthetic, and is commonly used if you were to undergo surgery and require nitrous oxide, as opposed to routine dental procedures.
Nitrous oxide, or laughing gas, is a colorless and nearly odorless gas used as a sedative to reduce anxiety during a dental visit or during surgery, and is delivered via tubing connected to small “mask” that is placed over your nose. There are varying degrees of sedation that can be achieved using nitrous oxide, the effects of which range from mild tingling and euphoria to drowsiness, depending on the level of the gas used, and its percentage mix with oxygen.
Nitrous Oxide has been used for dental treatments since its discovery in 1772, and is directed mainly at achieving the following outcomes: 

  • Reduce or eliminate anxiety
  • Minimize movement during dental treatment
  • Enhance the clarity of communication and aid patient cooperation
  • Temporarily increase one's pain threshold
  • Increase tolerance for longer appointments
  • Aid in treatment of the mentally/physically disabled or medically compromised patient
  • Reduce gagging
  • Enhance the effect of sedatives
