General Anesthesia, Each Additional 15 Minutes - Dental Procedure Code Description
This dental procedure code applies to the administration of anesthetic drugs once the first 30 minutes of sedation has elapsed. This code covers general anesthesia that is used when a person is unable to cooperate during a procedure, as in the case of special needs individuals, or in cases where significant pain and discomfort is expected as part of the procedure. General anesthesia of this type used in dentistry is also referred to as “deep sedation.”
General anesthesia works by depressing the autonomic nervous system to such a state that protective reflexes that would normally come into play during a surgery are prevented from occurring. Essentially, with this type of deep sedation, an individual is placed into a medically induced coma.
General anesthesia has many purposes including:
Analgesia — loss of response to pain;
Amnesia — loss of memory;
Immobility — loss of motor reflexes;
Unconsciousness — loss of consciousness;
Skeletal muscle relaxation.
General anesthesia in a dental setting is typically administered intravenously (IV) but can also be given as a gas that is inhaled. Because IV administered sedation is more rapid, however, and can reduce complications such as vomiting and irregular respiration, many anesthetists prefer to sedate intravenously.
A variety of drugs can be used to induce this level of unconsciousness, and because it renders an individual medically comatose, breathing assistance via tubing, or a mask is necessary. Occasionally, an anesthetist may pre-medicate a person to allow the anesthetic to function more efficiently, or to aid in the patient's overall comfort going into, or coming out of anesthesia. Such pre-medications may include Clonidine and Melatonin.
