Billing tips

Always verify the surgical code being billed (e.g., 33880-33891) does not include radiological supervision and interpretation; 75957 should only be billed when separately identifiable
Impact: Prevents automatic denial or recoupment of $271.39 for unbundling violations
Document all contrast injections, fluoroscopy times, and post-deployment angiography in the radiology report; incomplete documentation is the primary cause of medical necessity denials
Impact: Reduces denial rate from approximately 15-20% to under 5% with complete documentation
Bill modifier 26 when performed in hospital setting where facility owns the equipment; verify split between professional and technical components matches facility agreement
Impact: Ensures proper payment allocation and prevents overpayment recovery audits
Do not bill 75957 with completion angiography codes (75630) as this imaging is included in the TEVAR supervision and interpretation
Impact: Avoids denial for duplicate or bundled services worth up to $150+ in additional claims
For emergency cases, ensure documentation clearly indicates separate decision-making for imaging supervision beyond the surgical procedure itself
Impact: Strengthens medical necessity defense during audits, protecting full reimbursement
When billing with multiple endovascular repair codes, verify each imaging service has distinct documentation in the radiology report to support separate billing
Impact: Prevents denial of secondary imaging codes that may represent additional $271.39 per claim

Can CPT 75957 be billed with thoracic endovascular aortic repair surgery codes?

Yes, CPT 75957 can be billed separately with TEVAR surgery codes (33880-33891) as it represents radiological supervision and interpretation that is not bundled with the surgical procedure. However, verify payer-specific policies and ensure separate documentation exists in a radiology report.

What modifier should be used for CPT 75957 in a hospital setting?

Modifier 26 (Professional Component) should be used when billing CPT 75957 in a hospital setting where the facility owns the imaging equipment and bills the technical component separately. Without modifier 26, you may be billing for services not performed by your practice.

What documentation is required to bill CPT 75957?

A separate radiology supervision and interpretation report is required, documenting fluoroscopic guidance, pre-deployment angiography, post-deployment completion angiography, contrast details, device positioning confirmation, and any complications. This must be distinct from the operative note and signed by the interpreting physician.

How many RVUs is CPT code 75957 worth in 2025?

CPT 75957 has 8.39 total RVUs in 2025, consisting of 6.0 work RVUs, 1.23 practice expense RVUs (both facility and non-facility), and 1.16 malpractice RVUs, according to the CMS Physician Fee Schedule RVU25A released December 23, 2024.

What is the difference between CPT 75957 and 75958?

CPT 75957 covers endovascular repair of the thoracic aorta (chest region), while CPT 75958 covers placement of proximal extension prosthesis for endovascular thoracic aortic repair. Code 75958 is used for additional imaging when extending the original repair proximally toward the aortic arch.

Why was my CPT 75957 claim denied for medical necessity?

Medical necessity denials for 75957 typically occur when documentation lacks detail about the imaging performed, contrast injections, or post-deployment angiography. Ensure your radiology report clearly describes all imaging phases, measurements taken, device positioning confirmation, and clinical indication for the endovascular repair approach.
