CPT 33882: Thoracic Branched Endovascular Aortic Graft Repair

CPT code 33882 designates a branched thoracic endovascular aortic repair using an aorto–aortic tube device with a fenestration for placement of an additional stent graft into the left subclavian artery. This complex endovascular service encompasses preprocedure sizing and device selection, nonselective and selective catheterization (including the left subclavian artery), intraoperative imaging guidance and interpretation, and balloon angioplasty within the treatment zone. The code is clinically significant given rising use of endovascular techniques to treat thoracic aortic pathology while minimizing open surgical morbidity.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national-level context on clinical application and coding scope, payer coverage considerations, and benchmarking and policy-oriented content where available. The publication outlines what claims administrators and clinicians need to know about service inclusions in the code description, typical sites of service (hospital catheterization lab, hybrid OR, or interventional radiology suite), and procedural components bundled into the code.

This resource provides concise guidance on code intent and clinical context, a summary of payer coverage landscape, and references to related services and coding practice. Data not available in the input is clearly noted where applicable.

Billing Code Overview

CPT code 33882 describes endovascular repair of the thoracic aorta using a branched endovascular graft system (endograft or stent graft) that includes an aorto–aortic tube device with a fenestration for placement of an additional stent graft into the left subclavian artery. The procedure may include extension of the graft downward toward the celiac artery when needed. The service covers device sizing and selection, nonselective catheterization, selective catheterization of the left subclavian artery, imaging guidance and interpretation, and balloon angioplasty within the treatment zone.

Service type: Endovascular thoracic aortic branched graft repair (branched thoracic endovascular aortic repair)
Typical site of service: Hospital-based vascular surgery or interventional radiology suite; commonly performed in a catheterization lab or hybrid operating room under fluoroscopic imaging

Clinical & Coding Specifications

Clinical Context

A 72-year-old male with a symptomatic thoracic aortic aneurysm involving the proximal descending thoracic aorta and an anatomically involved left subclavian artery is evaluated for endovascular repair. Preprocedural workup includes contrast-enhanced CT angiography for sizing and planning, cardiopulmonary risk assessment, and informed consent discussing a branched endovascular graft repair with possible coverage of the left subclavian artery origin. In the hybrid endovascular suite, the vascular surgery and interventional radiology teams perform intraprocedural digital subtraction angiography and fusion imaging guidance. The operator deploys a branched aortic endograft (aorto–aortic tube device with a fenestration) and selectively catheterizes the left subclavian artery through the graft fenestration to place a covered stent into that branch. Nonselective catheterizations and imaging for device positioning are performed; balloon angioplasty within the treatment zone is used to optimize graft apposition. The procedure includes device selection and sizing based on preprocedure measurements, and completion angiography confirms exclusion of the aneurysm and branch patency. Typical sites of service are an endovascular operating room, hybrid OR, or hospital-based catheterization lab. The service type is an endovascular aortic repair procedure (branched thoracic endovascular aortic repair) performed by endovascular surgeons, vascular surgeons, or interventional radiologists, with intraoperative imaging and potential postoperative ICU or step-down monitoring for hemodynamic and neurologic observation.

Modifier	Description	When to Use

`50`	Bilateral procedure	Rarely applicable; use only if bilateral paired procedures are performed in same operative session and payer allows.
`51`	Multiple procedures	Use when other distinct procedures are performed in the same session and payer requires modifier for multiple CPTs.
`52`	Reduced services	Use if the service is intentionally reduced or not completed as originally planned.
`53`	Discontinued procedure	Use if the planned endovascular repair is terminated before completion for patient-related or intraoperative reasons.
`59`	Distinct procedural service	Use when a separate, distinct endovascular procedure not integral to the primary repair is performed and must be reported separately (per payer guidance).
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the operation.
`66`	Surgical team	Use when a surgical team approach is provided and reportable by payer policy.
`76`	Repeat procedure by same physician	Use when the same physician repeats the procedure subsequent to a prior attempt in the global period.
`77`	Repeat procedure by another physician	Use when another physician performs a repeat procedure after the initial attempt during the global period.
`78`	Unplanned return to the OR for a related procedure during the global period	Use when an unplanned return to the operating room for a related service occurs during the global period.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during the global period.
`LT`	Left side	Use when laterality needs to be reported for payer systems that require laterality modifiers (e.g., left subclavian branch work).
`RT`	Right side	Use when laterality needs to be reported for right-sided procedures or branches.
