What 00940 covers
Anesthesia professionals report 00940 for anesthesia during vaginal procedures that are not assigned a more specific anesthesia code, including vaginal biopsy. An anesthesiologists or CRNA provides anesthesia in settings such as an operating room or ambulatory surgery center, while the surgeon reports the operative procedure. The operative record should identify the procedure and site so the anesthesia service can be matched to the work performed.
Choose a more specific anesthesia code for vaginal hysterectomy, cervical cerclage, culdoscopy, or hysteroscopy or hysterosalpingography rather than 00940. The anesthesia record should identify the anesthesia service and document start and end times. Code 00940 has 3 base units. Medicare payment is (base units + time units) multiplied by the locality's anesthesia conversion factor, which varies by locality. 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.

00940 billing questions
When should 00940 be chosen instead of a neighboring vaginal anesthesia code?
Use 00940 for vaginal procedures without a more specific anesthesia code. Vaginal hysterectomy, cervical cerclage, culdoscopy, and hysteroscopy or hysterosalpingography have distinct neighboring codes.
Does 00940 cover the surgeon’s vaginal procedure?
No. The surgeon reports the operative procedure separately; 00940 represents the anesthesia service for that procedure.
How are anesthesia time units calculated for 00940?
Report anesthesia time in minutes. CMS converts it to 15-minute units, computed to one decimal place, and adds those units to the code’s 3 base units for payment.
What should the record support when 00940 is reported?
The operative record should identify the vaginal procedure and site. The anesthesia record should identify the anesthesia service and document its start and end times.
How does Medicare calculate payment for 00940?
Medicare multiplies the sum of the 3 base units and the time units by the anesthesia conversion factor for the payment locality.
