What 01922 covers
This service covers anesthesia during noninvasive imaging, such as MRI or CT, and during radiation therapy. An anesthesiologist or CRNA provides the anesthesia when the patient requires it to undergo the procedure. The imaging or radiation team performs its own service, while the anesthesia practitioner reports the anesthesia care.
Choose this code for anesthesia during noninvasive imaging or radiation therapy, rather than for diagnostic arteriography or venography (01916), cardiac catheterization (01920), or therapeutic interventional arterial radiology (01924). The anesthesia record should identify the procedure and document the anesthesia care, including start and end times. Medicare assigns 7 base units; payment is the sum of base and time units multiplied by the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place, from preparation for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
