What 00840 covers
00840 applies to anesthesia for an intraperitoneal operation in the lower abdomen when a more specific anesthesia category does not identify the procedure. It covers qualifying open or laparoscopic work within the peritoneal cavity, rather than surgery limited to the abdominal wall or performed outside the cavity. An anesthesiologist or CRNA reports the anesthesia service in the operative setting; the surgeon reports the operation under its own procedure code.
Select this category for otherwise unclassified lower abdominal intraperitoneal procedures; use the relevant procedure-specific anesthesia category for tubal ligation or named extensive pelvic operations. The operative record should identify the procedure, site, and approach, and the anesthesia record should support the service and document its start and end times. Medicare payment is (6 base units + time units) × the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place, starting when the practitioner begins preparing the patient for anesthesia and ending when personal attendance ends and the patient can safely be placed under postoperative care; the conversion factor varies by locality.

00840 billing questions
How is 00840 distinguished from anesthesia for an extraperitoneal lower abdominal procedure?
Use 00840 for qualifying work within the peritoneal cavity. Code 00860 is for an extraperitoneal lower abdominal procedure, so the operative compartment distinguishes them.
Should 00840 be used for a lower abdominal hernia repair?
A hernia repair has a more specific anesthesia category, such as 00830. Do not choose 00840 solely because the operative site is in the lower abdomen.
What should the operative and anesthesia records support?
The operative record should identify the procedure, site, and approach. The anesthesia record should support the anesthesia service and document its start and end times.
How are time units calculated for 00840?
Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place. Medicare payment uses 6 base units plus time units, multiplied by the locality’s anesthesia conversion factor.
Is 00840 the right category for tubal ligation or a named extensive pelvic operation?
Use a more specific category when it describes the operation: 00851 for tubal ligation, 00846 for radical hysterectomy, or 00848 for pelvic exenteration.
Does 00840 report the surgeon’s operation?
No. It reports the anesthesia service; the surgeon reports the operative procedure separately.
