removal of a portion or all of an organ would require general anesthesia in order to tolerate
such an extensive surgical procedure. General anesthesia is used for those procedures when
loss of consciousness is required for the safe and effective delivery of surgical services;
• Regional Anesthesia: the delivery of anesthetic medication at a specific level of the spinal
cord and/or to peripheral nerves, including epidurals and spinals and other central
neuraxial nerve blocks, is used when loss of consciousness is not desired but sufficient
analgesia and loss of voluntary and involuntary movement is required. Given the potential
for the conversion and extension of regional to general anesthesia in certain procedures, it is
necessary that the administration of regional and general anesthesia be delivered or
supervised by a practitioner as specified at 42 CFR 482.52(a).
The administration of medication via an epidural or spinal route for the purpose of
analgesia, during labor and delivery, is not considered anesthesia and therefore is not
subject to the anesthesia supervision requirements at 42 CFR 482.52(a). However, if the
obstetrician or other qualified physician attending to the patient determines that an operative
delivery (i.e., C-section) of the infant is necessary, it is likely that the subsequent
administration of medication is for anesthesia, as defined above, and the anesthesia
supervision requirements at 42 CFR 482.52(a) would apply.
• Monitored Anesthesia Care (MAC): anesthesia care that includes the monitoring of the
patient by a practitioner who is qualified to administer anesthesia as defined by the
regulations at §482.52(a). Indications for MAC depend on the nature of the procedure, the
patient’s clinical condition, and/or the potential need to convert to a general or regional
anesthetic. Deep sedation/analgesia is included in MAC.
- Deep sedation/analgesia: a drug-induced depression of consciousness during which
patients cannot be easily aroused but respond purposefully following repeated or
painful stimulation. The ability to independently maintain ventilatory function may
be impaired. Patients may require assistance in maintaining a patent airway, and
spontaneous ventilation may be inadequate. Cardiovascular function is usually
maintained. An example of deep sedation would be a screening colonoscopy when
there is a decision to use propofol, so as to decrease movement and improve
visualization for this type of invasive procedure. Because of the potential for the
inadvertent progression to general anesthesia in certain procedures, it is necessary
that the administration of deep sedation/analgesia be delivered or supervised by a
practitioner as specified in 42 CFR 482.52(a).
“Anesthesia services” in a hospital NOT subject to the anesthesia administration and
supervision requirements at 42 CFR 482.52(a):
• Topical or Local Anesthesia;
• Minimal Sedation: A drug-induced state during which patients respond normally to
verbal commands. Although cognitive function and coordination may be impaired,
ventilator and cardiovascular functions are unaffected. For example, a patient
undergoing an MRI or CT scan may receive minimal sedation with an oral
