What 00870 covers
This service covers anesthesia for an open extraperitoneal operation that reaches the urinary bladder through the lower abdomen to remove bladder calculi. An anesthesiologist or CRNA typically provides and reports the anesthesia in a hospital or other surgical facility. The operative service is commonly a cystolithotomy, such as the operation represented by CPT 51050; the surgeon’s record should establish the bladder incision and stone removal.
Choose this code for cystolithotomy, not for shock-wave treatment of urinary stones or a lower abdominal procedure without a more specific anesthesia category. The anesthesia record should identify the procedure and document the practitioner’s anesthesia start and end times. 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 for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; the conversion factor varies by locality.

00870 billing questions
When should I choose 00870 instead of 00860?
Use 00870 for anesthesia for extraperitoneal cystolithotomy. Code 00860 is for an extraperitoneal lower abdominal procedure that does not have a more specific anesthesia code.
Is shock-wave lithotripsy reported with 00870?
No. Anesthesia for extracorporeal shock-wave lithotripsy is classified under 00872 or 00873, depending on the treatment setup; 00870 is for cystolithotomy.
What should the operative and anesthesia records show?
The operative report should support an extraperitoneal bladder incision and removal of bladder stones. The anesthesia record should identify the procedure and document anesthesia start and end times.
How are Medicare units calculated for 00870?
The code has 5 base units, to which anesthesia time units are added before applying the locality’s anesthesia conversion factor. Time is converted from minutes into 15-minute units, computed to one decimal place.
Is 00870 the surgeon’s cystolithotomy code?
No. It reports the anesthesia service; the surgeon reports the operative procedure, commonly CPT 51050 for cystolithotomy without vesical neck resection.
