Thoracoabdominal Aortic Aneurysm (TAAA) Repair & Branched/Fenestrated EVAR (FEVAR) Medical Billing Services
Complex thoracoabdominal aortic aneurysm (TAAA) repair across Crawford Extents I–IV: fenestrated and branched endovascular aortic repair (FEVAR / BEVAR) with visceral vessel branch integration (celiac, SMA, renal arteries), open thoracoabdominal graft replacement, prophylactic spinal cord CSF drainage (62272), and multi-surgeon co-surgery.
Aethera Healthcare Solutions provides full-service medical billing and revenue cycle management to vascular surgeons, cardiothoracic aortic specialists, endovascular aortic reconstructive teams, and comprehensive aortic centers across the United States. We handle coding, claims, payment posting, denial management, and A/R follow-up end to end — so your team can stay focused on patient care while your revenue cycle runs cleanly.
Typical thoracoabdominal aortic aneurysm (taaa) repair & branched/fenestrated evar (fevar) CPT range we work: 33877, 34841, 34842, 34843, 34844, 34845, 34846, 34847, 34848, 62272, 36245, 37236, 99291, 99223.
Why thoracoabdominal aortic aneurysm (taaa) repair & branched/fenestrated evar (fevar) billing leaks revenue
Visceral vessel branch tier unbundling denials (34841-34848): Clearinghouses bundling multi-vessel fenestrated/branched visceral modules into single-branch codes, drastically discounting high-complexity 3-vessel and 4-vessel FEVAR
Prophylactic spinal cord protective lumbar CSF drainage (62272) bundling: Payers rejecting neuroprotective lumbar drainage catheter placement as inclusive to endovascular aortic repair
Vascular co-surgeon Modifier -62 matching failures: High-acuity open Crawford TAAA repairs requiring paired cardiothoracic and vascular surgeons failing reimbursement due to unaligned operative codes
Selective visceral catheterization add-on denials (+36245-+36247): Erroneous bundling of target visceral artery catheterization and bridging stent deployment into primary FEVAR deployment

Thoracoabdominal Aortic Aneurysm (TAAA) Repair & Branched/Fenestrated EVAR (FEVAR) billing FAQ
How are visceral branches coded under current CPT guidelines for FEVAR (34841-34848)?
CPT codes 34841–34848 specifically categorize fenestrated/branched endovascular aortic repair based on whether the endograft incorporates the abdominal aorta only (34841–34844) or the visceral aorta extending into the lower thoracic aorta (34845–34848), tiered by the exact number of visceral arteries revascularized (1, 2, 3, or 4 vessels including celiac, superior mesenteric, right renal, and left renal arteries). Each visceral artery revascularized must be explicitly identified in the operative summary.
Is prophylactic lumbar CSF drainage (62272) separately billable during thoracoabdominal aneurysm repair?
Yes. Prophylactic spinal cord protection via lumbar cerebrospinal fluid catheter placement (CPT 62272) to monitor and maintain spinal cord perfusion pressure (mitigating paraplegia risk) is performed prior to aortic cross-clamping or endograft deployment. Under CMS NCCI guidelines, CPT 62272 is separately billable with Modifier -59 or -XU, documented with pre-incision catheter placement and distinct physiological monitoring rationale.
