Billing tips

Always verify whether facility or non-facility rate applies; 75743 has identical rates ($143.29) for both settings in 2025, simplifying billing
Impact: Eliminates site-of-service payment differential concerns, but documentation of setting still required
Do not separately bill catheter placement codes (36013-36015) with 75743 when performed for the same pulmonary angiography study
Impact: Prevents automatic denials; catheterization is included in the imaging supervision and interpretation
Bill modifier 26 when interpreting physician is different from the facility providing technical resources; confirm split-billing arrangement in advance
Impact: Ensures correct payment distribution; professional component typically represents 30-40% of total RVUs
Document laterality (right, left, or bilateral pulmonary arteries) and number of injections in radiology report to support medical necessity
Impact: Reduces audit risk and supports appeals; specific anatomic documentation prevents downcoding
When billing with interventional procedures, verify that 75743 represents diagnostic angiography separate from roadmapping or confirmatory imaging
Impact: Prevents bundling denials; diagnostic angio before intervention may be separately billable with modifier 59
Capture Work RVU 1.66, PE RVU 2.62, and MP RVU 0.15 (total 4.43 RVUs) in productivity reports to justify radiologist staffing needs
Impact: Supports resource allocation decisions; 4.43 RVUs at $143.29 represents moderate-complexity diagnostic study

Can I bill CPT 75743 with cardiac catheterization codes on the same day?

Yes, but only if the pulmonary angiography represents a separate diagnostic study distinct from roadmapping or confirmatory imaging for the intervention. Use modifier 59 and document the separate nature of the diagnostic imaging in the operative report.

What is the difference between CPT 75743 and 75746?

CPT 75743 is for selective pulmonary angiography with catheter positioned in pulmonary arteries, while 75746 is for non-selective pulmonary angiography with catheter in main pulmonary artery or right ventricle. Selective placement (75743) provides more detailed imaging of specific pulmonary vessels.

Do I need modifier 26 or TC when billing CPT 75743?

Use modifier 26 if you are only billing for the professional interpretation component as the reading physician. Use modifier TC if the facility is billing only the technical component (equipment and staff). Bill without modifiers only if providing the complete global service.

Is prior authorization required for CPT 75743?

Prior authorization requirements vary by payer. Medicare Advantage plans and many commercial insurers require prior authorization for pulmonary angiography. Verify with the specific payer before scheduling, as non-authorized services may result in complete denial.

What diagnosis codes support medical necessity for CPT 75743?

Common supporting ICD-10 codes include I26.xx (pulmonary embolism), I27.xx (pulmonary hypertension), Q25.xx (congenital pulmonary artery malformations), R06.02 (shortness of breath), and R91.1 (solitary pulmonary nodule). Documentation must link the diagnosis to the clinical indication for invasive angiography.
