CPT 75956Radiology

Xray endovasc thor ao repr

CPT code 75956 covers X-ray imaging performed during endovascular repair of the thoracic aorta (the main artery in the chest). This imaging helps guide the physician during minimally invasive procedures to fix damaged sections of the aorta using catheters and stents inserted through blood vessels.

Billing tips

Always verify the procedure includes all components of radiological supervision: initial diagnostic angiography, roadmapping, stent-graft deployment imaging, and completion angiography
Impact: Missing documentation of any component may result in denial or downcoding, losing the full $316.67 reimbursement
Bill 75956 only once per operative session regardless of number of stent-grafts deployed or imaging sequences performed during a single thoracic aortic repair
Impact: Duplicate billing will result in denial of second claim; all imaging is bundled into single code
Do not unbundle component imaging codes (75600, 75605, 75625) when 75956 is appropriate; the comprehensive code includes all thoracic aortic imaging
Impact: Unbundling may trigger audit and recoupment of approximately $150-400 in overpayments plus penalties
Ensure separate documentation of the radiological supervision and interpretation report distinct from the operative note
Impact: Missing separate S&I report is a leading cause of denial; requires appeal process delaying payment 60-90 days
Verify payer-specific policies on same-day diagnostic angiography (75600-75630); many require modifier 59 when medically necessary diagnostic imaging precedes intervention
Impact: Proper modifier use can secure additional $200-500 for diagnostic imaging when appropriately documented as separate service
For hybrid procedures involving both open and endovascular components, confirm whether both surgical repair codes and 75956 are separately billable per payer policy
Some payers bundle all imaging into surgical code; clarification prevents $316.67 denial

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 75956 in 2025?

The 2025 Medicare national average reimbursement rate for CPT code 75956 is $316.67 for both facility and non-facility settings. This rate is based on 9.79 total RVUs (7.00 work RVU, 1.42 PE RVU, 1.37 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Can CPT 75956 be billed with the primary TEVAR surgical code?

Yes, CPT 75956 is separately reportable with the primary endovascular thoracic aortic repair codes (33880-33891). The CPT manual specifically indicates that 75956 represents the radiological supervision and interpretation component and is not bundled into the surgical procedure codes. However, always verify payer-specific policies as some commercial insurers may have different bundling rules.

What is the difference between CPT 75956 and 75957?

CPT 75956 covers radiological supervision and interpretation for endovascular repair of the descending thoracic aorta, while 75957 covers the same service for the ascending or transverse thoracic aorta. The anatomic location of the repair determines which code to use. Both codes have the same RVU value and reimbursement rate.

Does CPT 75956 require a separate written report?

Yes, CPT 75956 requires a separate written radiological supervision and interpretation report that is distinct from the operative note. This report must document all imaging performed, interpretations, measurements, and findings including completion angiography and endoleak assessment. Failure to provide a separate S&I report is a common reason for claim denials.

How many times can CPT 75956 be billed during a single TEVAR procedure?

CPT 75956 should be billed only once per operative session regardless of the number of stent-grafts deployed or imaging sequences performed. All radiological supervision and interpretation during a single thoracic aortic repair is bundled into one unit of 75956. Billing multiple units will result in denial of duplicate claims.

What modifiers are commonly used with CPT code 75956?

Common modifiers for CPT 75956 include modifier 26 (professional component only) when the physician interprets but doesn't own the equipment, modifier TC (technical component) when billing only for equipment and technical costs, and modifier 59 (distinct procedural service) when billed with other procedures that might be considered bundled. Modifier 52 may be used for reduced services when complete imaging protocol cannot be performed.

Can diagnostic angiography codes be billed separately with CPT 75956?

Diagnostic angiography performed during the same session as TEVAR may be separately billable only if it is a distinct diagnostic study performed for different clinical indications and documented as medically necessary prior to the decision to intervene. Use modifier 59 to indicate a separate service and provide clear documentation of the medical necessity. Many payers consider diagnostic imaging performed immediately before intervention as included in 75956.
