Anesthesia Time and Calculation of Anesthesia Time Units



Anesthesia time is defined as the period during which an anesthesia practitioner is present with the patient. It starts when the anesthesia practitioner begins to prepare the  patient for anesthesia services in the operating room or an equivalent area and ends when the anesthesia practitioner is no longer furnishing anesthesia services to the patient, that is, when the patient may be placed safely under postoperative care. Anesthesia time is a continuous time period from the start of anesthesia to the end of an anesthesia service. In counting anesthesia time for services furnished on or after January 1, 2000, the anesthesia practitioner can add blocks of time around an interruption in anesthesia time as long as the anesthesia practitioner is furnishing continuous anesthesia care within the time periods around the interruption.


Actual anesthesia time in minutes is reported on the claim. For anesthesia services furnished on or after January 1, 1994, the A/B MAC computes time units by dividing reported anesthesia time by 15 minutes. Round the time unit to one decimal place. The A/B MAC does not recognize time units for CPT codes 01995 or 01996.

For purposes of this section, anesthesia practitioner means a physician who performs the anesthesia service alone, a CRNA who is not medically directed, or a CRNA or AA, who is medically directed. The physician who medically directs the CRNA or AA would ordinarily report the same time as the CRNA or AA reports for the CRNA service.


H
. Base Unit Reduction for Concurrent Medically Directed Procedures 

If the physician medically directs concurrent medically directed procedures prior to January 1, 1994, reduce the number of base units for each concurrent procedure as follows.

• For two concurrent procedures, the base unit on each procedure is reduced 10 percent.

• For three concurrent procedures, the base unit on each procedure is reduced 25 percent.

• For four concurrent procedures, the base on each concurrent procedure is reduced 40 percent.

• If the physician medically directs concurrent procedures prior to January 1, 1994, and any of the concurrent procedures are cataract or iridectomy anesthesia, reduce the base units for each cataract or iridectomy procedure by 10 percent.
