How are anesthesia codes grouped?

Anesthesia codes are grouped according to the type of procedure performed. The main groups of anesthesia codes are:

* General anesthesia codes (00100-01999): These codes are used for procedures in which the patient is completely unconscious and unable to feel pain.

* Regional anesthesia codes (02000-02999): These codes are used for procedures in which a local anesthetic is used to block pain in a specific area of the body.

* Monitored anesthesia care codes (03000-03999): These codes are used for procedures in which the patient is given medication to make them drowsy and relaxed, but they are still conscious and able to breathe on their own.

* Conscious sedation codes (04000-04999): These codes are used for procedures in which the patient is given medication to make them drowsy, but they are still awake and able to respond to commands.

* Local anesthesia codes (05000-05999): These codes are used for procedures in which a local anesthetic is used to block pain in a small area of the body.

Each group of anesthesia codes is further divided into subcategories based on the specific procedure performed. For example, general anesthesia codes are divided into subcategories for procedures performed on the head and neck, chest, abdomen, and extremities.
