CPT 00770: Anesthesia for Major Abdominal Vascular Procedures
CPT code 00770 denotes anesthesia services for major abdominal vascular procedures such as embolectomy, thrombectomy, aneurysm repair, bypass grafts and venous anastomosis. This code captures perioperative anesthesia care for high-acuity, invasive vascular surgeries that carry significant physiologic risk and resource use. Nationally, accurate coding of 00770 matters for clinical reporting, anesthesia staffing, and appropriate claims adjudication for complex vascular cases.
Key payers considered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and the Medicare program. Readers will find a concise explanation of the clinical context for 00770, typical sites of service, and how this anesthesia code relates to other anesthetic service codes for abdominal procedures. The publication also summarizes commonly observed billing modifiers and associated clinician taxonomies, highlights relevant ICD-10 diagnostic contexts for vascular occlusion and stenosis, and notes closely related anesthesia codes used for intraperitoneal and upper abdominal procedures.
The content is intended to orient coding professionals, billing staff, and clinical leaders to the purpose and clinical scope of CPT code 00770, provide clarity on common coding adjacencies, and identify practical reference points for payer discussions and internal documentation practices.

National Reimbursement Benchmarks
BUCA (average commercial) sits near the center of the national distribution for CPT 00770 with a mean rate of $71.60 and an interquartile spread from $49.90 to $91.70. Among individual commercial payers, Cigna posts a relatively high mean ($92.70) and a notably wide IQR ($121.70 - $68.00 = $53.70), reflecting greater dispersion in commercial contract rates. Aetna’s IQR ($102.70 - $44.00 = $58.70) is the widest, driven by a high upper quartile and a low lower quartile despite a mean of $81.50.
Blue Cross Blue Shield shows a tighter middle distribution (IQR $81.70 - $45.20 = $36.50) and a median ($57.00) close to BUCA’s median-equivalent, while UnitedHealth Group has one of the narrowest IQRs ($80.80 - $52.00 = $28.80) suggesting more consistency across contracts.
