Summary & Overview
HCPCS M0301: Fabric Wrapping of Abdominal Aneurysm
HCPCS Level II code M0301 represents fabric wrapping of an abdominal aneurysm, a surgical procedure used to reinforce the aortic wall during repair of an abdominal aortic aneurysm. This code captures a specific adjunctive technique in vascular surgery and is relevant for hospitals and vascular surgery groups managing complex aneurysm cases. Nationally, accurate coding for adjunctive aneurysm procedures affects procedure-level reporting, resource use classification, and payment pathways tied to inpatient surgical care.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context and service setting for M0301, plus an outline of typical coding considerations where available. The publication also summarizes what practitioners and billing professionals need to know about where this service is commonly performed and why correct use of this HCPCS Level II code matters for administrative and clinical records.
Content highlights include clinical context for fabric wrapping in aneurysm management, payer coverage scope (national payers listed above), and note of missing input elements. Data not available in the input: associated taxonomies, ICD-10 diagnoses, specific payer policy details, reimbursement benchmarks, and related codes. The piece is intended as a national-level reference for coding, billing, and administrative staff involved in vascular surgery reporting.
Billing Code Overview
HCPCS Level II code M0301 describes fabric wrapping of abdominal aneurysm, a surgical adjunct procedure involving placement of fabric material around an abdominal aortic aneurysm to reinforce the vessel wall. This service is a surgical repair/support procedure typically performed in an inpatient surgical setting or an operating room within a hospital, often as part of vascular surgery for aneurysm management.
Service type: Surgical procedure — vascular/aneurysm repair
Typical site of service: Hospital inpatient or operating room (inpatient surgical care)
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a known infrarenal abdominal aortic aneurysm (AAA) measuring 5.8 cm on surveillance imaging is admitted electively for open surgical repair with fabric wrapping of the aneurysm (M0301). The patient has a history of peripheral arterial disease and controlled hypertension. Preoperative evaluation includes CT angiography to define aneurysm extent and renal arteries, cardiopulmonary risk assessment, and laboratory studies. Intraoperatively, after midline laparotomy and exposure of the aneurysm, the vascular surgeon places a synthetic fabric wrap around the aneurysmal sac to reinforce the aortic wall and reduce expansion risk when formal graft replacement is not feasible or as an adjunct to repair.
Postoperatively the patient is monitored in a surgical step-down or intensive care unit for hemodynamic stability, renal function, and wound status. Typical clinical workflow includes preoperative consent and documentation of indication (e.g., enlarging AAA, symptomatic aneurysm, or adjunct to prior endovascular/staged repair), intraoperative operative note documenting use of fabric wrap and technical details, and postoperative progress notes documenting recovery, complications, and follow-up imaging plan.
