CPT code 00800: Abdominal wall anesthesia, other lower anterior wall procedures2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 00800 covers

This code represents anesthesia for surgery involving the lower front abdominal wall when no more specific anesthesia category identifies the operation. An anesthesiologist or CRNA provides the anesthesia service and reports it separately from the surgeon’s procedure, commonly in a hospital or ambulatory surgical setting.

Select a specific anesthesia code for panniculectomy, lower abdominal hernia repair, posterior abdominal wall work, or procedures within the lower abdomen rather than this general anterior-wall category. The operative report should identify the operation and site; the anesthesia record should document the service and anesthesia start and end times. Code 00800 has 4 base units, and Medicare payment is base units plus time units, multiplied by the locality’s anesthesia conversion factor. Anesthesia time is counted in minutes and converted to 15-minute units to one decimal place, from when the practitioner begins preparing the patient for anesthesia until the practitioner is no longer personally attending and the patient can safely enter postoperative care; the conversion factor varies by locality.

How the 00800 rate is calculated

Payment rules and modifiers for 00800

00800 has no global surgery period, no multiple-procedure, bilateral or assistant-at-surgery adjustment, and no professional/technical split. What changes the payment is where the service happens: the place of service on the claim decides whether Medicare pays the office or the facility rate.
