Definition:

Type of anesthesia administered on the patient during the stay. If during the stay, anesthesia is administered more than once, the level of anesthesia is reported in the following hierarchical order: General, Regional, Other, and Local.

Codes and Values:

     1.    "00" = No Anesthesia

"10" = Local Anesthesia

Administered by the infiltration of a local anesthetic agent at the body site where pain might originate during the procedure. Local anesthesia is typically administered by the surgeon or other health care provider performing the procedure. Anesthesia care providers sometimes monitor the patient during the administration of local anesthesia by the surgeon or other provider, in which case the anesthetic procedure is sometimes referred to as "local/MAC". In this term, MAC stands for "Monitored Anesthesia Care".

"20" = General Anesthesia

Administered by the intravenous injection of anesthetic agents, the inhalation of anesthetic agents, or (more often) a combination of the two. Anesthetic agents are sometimes (but infrequently) administered by other routes, such as via the nasal or rectal mucosa. General anesthesia involves loss of consciousness and loss of protective reflexes.

"30" = Regional Anesthesia

Administered by injecting a local anesthetic agent to interrupt nerve impulses on large nerves or nerve roots serving relatively large segments of the body. Included under the term regional anesthesia are the following: spinal anesthesia, epidural anesthesia, caudal anesthesia, brachial plexus anesthesia (including axillary block, interscalene block, supraclavicular block), sacral nerve block, femoral nerve block, and ankle block. (This list is not exhaustive.)

"40" = Other

Any anesthetic that does not fit one of the above categories should be classified "other". Analgesia or sedation that is administered to make a patient more comfortable during a procedure but does not involve loss of consciousness or loss of protective reflexes would come under this category.
