What 00846 covers
00846 is for anesthesia provided during an intraperitoneal radical hysterectomy in the lower abdomen and pelvis. The operation removes the uterus and cervix with surrounding pelvic tissue and may be performed through an open incision or laparoscopically. An anesthesiologist or CRNA reports the anesthesia service, commonly for an operating-room procedure.
Select 00846 when the procedure is a radical hysterectomy, rather than another lower abdominal intraperitoneal operation represented by 00840 or pelvic exenteration represented by 00848. The operative report should establish the procedure performed, and the anesthesia record should document the anesthesia service and its start and end times. Medicare payment is (8 base units + time units) × the anesthesia conversion factor for the locality. Anesthesia 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.

00846 billing questions
When should 00846 be chosen instead of 00840?
Use 00846 for anesthesia for a radical hysterectomy. Code 00840 is for other lower abdominal intraperitoneal procedures when a more specific anesthesia code does not describe the operation.
How does 00846 differ from 00848?
00846 identifies anesthesia for radical hysterectomy. Code 00848 is for pelvic exenteration, a distinct pelvic operation.
What should the operative report show?
It should establish that the operation was a radical hysterectomy rather than another lower abdominal procedure. The anesthesia record should support the practitioner’s service and anesthesia time.
How are anesthesia time units calculated for 00846?
Report anesthesia time in minutes; CMS converts it to 15-minute units to one decimal place. The interval starts with preparation for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
What base units does Medicare assign to 00846?
The code has 8 base units. Medicare calculates anesthesia payment using base units plus time units, multiplied by the conversion factor for the payment locality.
How is payment handled when an anesthesiologist medically directs a CRNA?
When the anesthesiologist medically directs a CRNA, Medicare pays each 50% of the allowance for the personally performed service. The anesthesiologist reports QK or QY, and the CRNA reports QX.
