What 00950 covers
Culdoscopy is an endoscopic approach into the pelvic cavity through the posterior vaginal fornix, used to inspect or access the cul-de-sac. An anesthesiologist or CRNA reports anesthesia for this procedure; the procedural clinician reports the operative service separately.
Select 00950 when the operative record documents culdoscopy, rather than a nonspecific vaginal procedure (00940) or hysteroscopy or hysterosalpingography (00952). The operative report should identify culdoscopy and its route, and the anesthesia record should support anesthesia time. This code has 5 base units; Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. Time is counted in minutes and converted to 15-minute units to one decimal place, from preparation until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; conversion factors vary by locality.

00950 billing questions
When should I choose 00950 instead of 00940?
Use 00950 when the operative documentation identifies culdoscopy through the vaginal fornix. Code 00940 is for vaginal procedures without a more specific anesthesia category.
How is 00950 different from anesthesia for hysteroscopy?
Culdoscopy accesses the pelvic cavity through the vaginal fornix. Hysteroscopy or hysterosalpingography accesses the uterine cavity through the cervix and is represented by 00952.
What should the records show?
The operative report should identify culdoscopy and its vaginal route. The anesthesia record should document the anesthesia service and support the reported time.
How are Medicare anesthesia units calculated for 00950?
The code has 5 base units. Medicare adds time units, calculated from minutes in 15-minute units to one decimal place, then applies the anesthesia conversion factor for the payment locality.
Is the surgeon's culdoscopy included in the anesthesia claim?
No. The procedural clinician reports the culdoscopy separately; 00950 represents the anesthesia service for that procedure.
