What 00851 covers
This code covers anesthesia for intraperitoneal tubal sterilization. Laparoscopic approaches may occlude or destroy the fallopian tubes; the surgeon reports the sterilization procedure separately. An anesthesiologist or other qualified anesthesia practitioner reports the anesthesia service.
Select 00851 for intraperitoneal tubal ligation rather than other lower-abdominal operations. Code 00840 is used for other intraperitoneal lower-abdominal procedures, while 00860 applies to extraperitoneal lower-abdominal procedures. The operative report should identify the sterilization procedure and approach; the anesthesia record should support the service and its start and end times. Medicare payment is the 6 base units plus time units, multiplied by the anesthesia conversion factor, which varies by locality. Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place, starting with preparation for anesthesia and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.

00851 billing questions
When should I choose 00851 instead of 00840?
Choose 00851 for anesthesia for intraperitoneal tubal ligation. Use 00840 for other intraperitoneal lower-abdominal procedures that do not fall under a more specific anesthesia code.
Does 00851 include the surgeon’s tubal procedure?
No. 00851 represents the anesthesia service; the surgeon reports the tubal ligation or occlusion separately.
How are units calculated for 00851?
The code has 6 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, then multiplies the total by the locality’s anesthesia conversion factor.
What should the operative and anesthesia records show?
The operative report should identify the intraperitoneal tubal sterilization procedure and its approach. The anesthesia record should support the anesthetic service and the start and end times used for time units.
How does Medicare handle medical direction of a CRNA?
When an anesthesiologist medically directs a CRNA, Medicare pays each 50% of the allowance for the personally performed service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
